Big turbo? No thanks!

I've spent months dipping into the various big turbo threads, whether it be Fraser's E3YOB or Steve's V6RUL and one thing these threads seem to have in common is they way they have turned into absolute epics of aggravation. They appear to be a litany of trial and error, with success followed by disaster and changes of direction resulting in unanticipated additional expense and a history of wasted money. From the outside it so often looks like they have embarked on a journey of no return, which once started has to be completed or be left with what is little more than a very expensive but undriveable bundle of scrap only fit for breaking. After months and months of work and in each case tens of thousands of pounds spent (and I'm sure both would admit at times pounds wasted) neither have yet got a driveable car. Now hopefully both will finally get to where they hope to be some time soon, but without doubt a final bill well in excess of what they ever anticipated. And even then the question remains whether they are going to have a car that is any way relaiable? There's certainly plenty of history of big turbo conversions that have been anything but (Gizmo's, for instance) and even those that appear to have done well have their problems eventually (such as MattB's car that is currently 'poorly'). So does embarking on the big turbo route inevitably mean an endless journey of throwing good money after bad?

Now I don't know Fraser and have never seen his car or discussed his motivations, but I do know Steve and have had the chance of a ride in his car on one of the occasions it's actually been running and not in the garage. Yes, it is bloody quick! And yes, I do understand the desire to have a bit of a sleeper or even to wrap up supercar performance in the classically beautiful TT package. But at what cost, and is that dream realistically achievable? When Steve first told me about what he was planning and what it was likely to cost my first thoughts were, "Why don't you just buy a Porsche?" At least then you get the performance in a car put together by a team of some of the motor industry's best engineers backed up with the massive development budgets of one of the biggest car manufacturer's in the world, rather than the efforts of a bloke in a unit on a back street industrial estate somewhere!

Now perhaps you could make an argument that these specialist tuners know what they are doing, but reading through both these build threads suggests otherwise. If they were really that good wouldn't they be working for Porsche or some racing team somewhere? Hollie is about to have a go at it and I have to say I think it's a very brave move. Really, is there anybody out there whom you can trust to do a conversion on your car, get it right first time and with an agreed price and deliver you a car that has both performance and reliability? I have my doubts. We certainly see little evidence of it here.

People have been doing these conversions for quite some time, so you'd think with the Forum's collective knowledge there would be some concensus by now of what is the best way to do it. So if there is a definitive big turbo conversion where and what is it? And I'd love to hear from the pioneers who have given it a go. Knowing now what you didn't know then and what it's cost you in the end in both time and money, was it really worthwhile? In hindsight would you still have bothered, or would it have made more sense to have bought that Porsche after all?

In the end I do genuinely hope Steve and Fraser's cars come together and no doubt they will have something special and unique to drive and may even have enjoyed the process in some way, and I wish Hollie every bit of luck with her project. But personally I think it looks like a classic case of "more money than sense". Great if you've a bottomless pit of cash to throw at it, but a real money-pit otherwise.

It's not for me. What does everyone else think?

I struggle to understand the motivation to spend that much money on something that will ultimately be worse that the equivalent costing sports car. You might be able to propel a TT down a drag strip faster than a 997 turbo (although that's not guaranteed) but it's never going to handle like one.

I do get the desire to do something different and the engineering side appeals to me (at least Fraser has got his hands dirty with his, which sort of justifies it) but it still comes back to the massive expense. For a fraction of the price you could build a Caterham style kit car, which would give you a lot more satisfaction than handing your credit card to a tuner.

Comparing my build to Steves is like comparing apples and oranges. Lots of people do think, why don't you just buy a Porsche but for me the specifying and building is the fun part, even if it doesn't seem like that looking in sometimes :) I would not agree with you stating that my build is epic aggravation and I have not wasted any money. My engine build started in July and will be fully tuned come beginning December.

When you say tuners in my case there is has not just been a single company, there has been quite a few. The tuner is actually Morgan at Vagcheck who is currently writing the map to suit my engine and components. I am doing quite a few things on my car that I have not seen been done before and there is certainly a need for trial and error.

I didn't choose a simple route for my BT build. The YOB build does go someway past the average BT build. I get a lot of satisfaction from seeing a perfectly fabricated manifold, the roar of the engine on first start, the people and companies I have met on the way, the Rolling Road Shootout day etc. Building a car such as the YOB is expensive yes but imho much more satisfying than just buying a porsche.

Really it's horses for courses at the end of the day. My car will be done soon and then I have the whole of next year to plan where I am going to drive it.

I love learning things and I have learnt a hell of a lot doing the car and met some great people along the way. I think you are possibly looking at it rather simplistically maybe.

Look at James BT conversion. 2 weeks start to finish... There is an answer to your question I guess. If you want a BT build completed quickly and want moderate power, the tried and tested route, go to the TT shop.

My build has gone how I have wanted it - but obviously I would have liked it to come together quicker. I cannot really agree with most of what you have said though as there has not been good money after bad, it has just been time. It is like any big project that involves multiple companies. It needs project managing.

I think it's a great idea! Lol!
Yes, you do need to go into it knowing it's going to cost you lots of cash, but that's a decision that you take when you start the process! I could have bought whatever car took my fancy, but liked the challenge of making this TT quick! When I say quick, I mean really quick!
It was all about the challenge for me, to see what was possible!
Yes I could have gone and bought a Porsche 997 Turbo but that wasn't what I wanted!
Anyway, having completed 3 BT conversions to date, on the same car, I believe I have reached the end of this specific route for this car! So I'm now selling mine, although its highly unlikely I'll find a buyer at the price I want, that I can then spend this money again in doing the same thing all over again, although this time in a slightly different way.
For me it's all about the challenge!
I've had fast cars all my life, TVR's Porches, Merc AMG's but the driving I've really loved is in the cars that I've been able to 'play' with. It started on original mini's dropping in Metro Turbo engines and playing around with Jack Knight Dog Boxes etc etc. That was fun! I was a member of the mini owners club and surrounded by people all round the country that you'd share ideas and development possibilities. It was fun and gave a great sense of belonging, no different to the TTOC!
So back to your question, I think this route has now been suitably developed with a GT28 and standard internals that give good gains with a good level of reliability. This has only come from the development that had been tested over and over by the likes of Sam, Caney etc. The difference with that to what Steve and Frase are currently trying and what Caney and I have done with ours is push the boundaries! The more people try these conversions, the more we learn, the more likely that reliability will follow, but this will take quite a number of cars going through this development process.
So the way I see it is we're the pioneers and from this will come the knowledge to allow others to follow and to me that's exciting, fun and fulfilling!
Try putting your foot down at the end of the drag strip with 550bhp under the pedal and tell me it's not a massively exciting experience! I know both me and Caney feel the same everytime we pull up at the end of the strip and in a car that we've pushed the development of it just makes it even more of a thrill.

If you want reliability, buy a Honda not a TT, if you follow a BT conversion just make sure you know what your getting yourself in for and be sure it's the route you want to take!

Anyway, if you want a reliable BT TT with huge power, just take a look at the for sale section, I'd be happy to hear from you!

:)

Wow didnt know their was such strong anti BT feelings among our fraternity. Obviously I disagree as I am one of those that has had it done. All at the TT shop I might add , and a mighty professional job they did too.

I have had many characterful cars RS4 , S4 etc etc but I wanted something different that was tuneable and found it in a QS.
Just buying a porsche 911 isnt the answer . Wheres the fun in that ? In my experience a lot of supposed performance cars are not as good as the maker claims e.g Boxster , Z4 , Lotus Elise ( A pile of **** by the way ) etc etc.

In reality the one thing a TT 1.8T lacks is character and the BT conversion injects this into the car giving it a personality that a plastic bath tub with a rover engine will never have IMHO. I love the old school power delivery and its addictive to drive.

And you can make them handle and stop like a 911 too. Just needs some thought and money to make it happen.

And last but not least it makes the TT a huge bundle of fun that I reckon takes some beating.

May I just say, that it is each to his own and we are not all the same and it is great to see two people with opposing opinions on a subject eloquently putting their point of view without running each other down or argueing.

Long may we continue to have a varied membership who all get on.

Personally, I am of the same opinion as the original poster, but I really enjoyed reading Steves write up and what motivates him to do big power conversions, and I would defend his right to do that.

I think if you walk into the likes of the TT Shop and throw them a loads of cash then you'll end up with a nice big power increase with added reliability but... I have huge respect for the over 400bhp members that have endeavoured to go that bit further and push for more exciting builds, often moving the boundaries and testing out new ideas :)

I though the TT Shop only produced BT Conversions around the 330 - 350 mark!?

Don't get me wrong I think that these are great as they do bring a level of reliability!

Simples... Hes never been in owned one! All my cars drive fantastically well... I ve not had any running down issues ie breaking down and rebuilding... Just slowly does it a bit at a time... As for the V6 route I think speak to any tuner... This is the hardest one to get hugh power... However without the issues people like Steve Collier and Frazer have gone through and a different untried route... Not only for there pleasure but their experiences they have shared along the way, Without these kind of individuals most of you would have never known what a BT Car looks or goes like... Or have any idea of issues or problems these individuals have encounted. I ve driven the slower version of both V Spurs and Caney at 450 BHP and the car drives really well and can easily handle the power, if not only the build is done correctly, but the suspension, brakes and handling side are done alongside, the car drives, even better than most manufactured cars. I m one of the only Individuals on the forum to own two of the best tuners cars and can tell you of the high build quality. I am aware of the issues some people have suffered using old type models to do these conversion, through ie the management system etc. As the BT conversions have moved on, so has ghe quality and the reliablity, and I am also aware that numerous of the companies have added or enhanced there performance kits. As for a porsche, there totally boring and unless you have 130k plus all cost for the RS Models its a pointless debate... We may as well be talking about R8s and M3s..... Most could have a TTRs but again, heavy porsche money.. And not as enjoyable to drive. How would I know... I only bought one and sold it, as its in no way the same bracket as the MK1. I ve done many a debate on this forum, and from what I know is going on behind the scenes with numerous forum members and numerous tuners, I can say theres more excitement and debate to follow.Small examples better turbos and enhanced engines..at a reduced budget.......

cmon lol TT handle like a 911........ thats where you have to draw the line, go and stop like one ofc you just spend money but you wont get handle like one.

I think the reason half the people are on the forum is to modify their cars, and a BT is just another modification so im all for it in that sense. Would i pay ÂŁ7k for 350bhp when i can get 280bhp from a remap and couple of bolt on bits and have lower down power band which is much more useable day to day no. Main reason is why would i spend the same value of the car on a mod? but for those who do i enjoy reading about the ups and downs :D

That's what I meant mate... still a good increase over the usual Stage 2 figure (tony not included, lol) :wink:
How's yours coming along, any developments since we last spoke?
Not really done a lot this year as most of my time and money has gone on silly maintenance costs for abnormal issues. Still one thing to finally sort and fingers crossed that will be at end of month when I change the fuel pump.

I started with Mini's too. Bought mine at 16 and built it from a shell. By the time I was 17 and passed my test it was finished. I just loved the moment I was able to drive it. So I supposed nothing has changed. I am 17 again and will be getting into my mini for the first time soon after building it. :lol: :lol: :lol:

YES!

The thing with the TT is that you still have the capability of playing with the hardware more so than than the new cars today!

Its quite an interesting topic this one and thanks Mark for bringing it to the fore..

My personal thoughts on why..

When i first came onto the forum my TT was standard, which was May 2009 and i was working in Manchester and living in Liverpool, so my TT was my daily. The contract i was on came to a natural end and i was left looking for new opportunities.
Unfortunately i was only offered offshore work providing i got all the nessessary training in place, survival, medicals [coet], MIST and COMPEX, after a few weeks all was in place and off i went offshore for the first time. This was an eye opener for me as there was nothing on board that floated my boat and the boredom set in quickly. I decided after this work period that there was no way i could go offshore or away from home unless i had a crutch in place to take my mind off the monotony whilst not at work.

This is where the TT [Cecille] came in to her own, she would be used as my crutch whilst i'm away, with the instruction to the indie that pictures would be taken and e-mailed to me so i could build up a story board and interest for me to keep me occupied, which had a secondary benefit to anybody that wanted to be bored with my info.

I have and still am away from home over 2 years later, after working offshore,Nottingham,Holland,UAE,Macedonia and now back offshore again off Aberdeen on the Montrose where i expect to be here for the next few months. [When offshore i do not work more than 3 weeks without coming home for at least 1 week].

This working away from home has earned me a lot of money and i choose to spend that money on something that floats my boat and keeps me occupied which just so happened to be the TT. This could have been any car that i owned at the time, whether it be a Porsche, Merc, BMW or Audi, it would have got the treatment. I have always been interested in cars and as a youngster i sought higher power and louder exhausts and frequented the boy racer scene, but for the last 20 years i have been focused on other priorities, but working away from home has brought me round full circle again to something that i enjoyed as a lad.

So, for me, my reasons for butchering my beloved Cecille is more about lonliness rather than chasing numbers, but i must admit however that since the turbo build started i have decided to join the "how fast" club and experiance a different type of fulfilment with, the renamed [Janice]. Im up for pushing the boundries and trying to set higher standards and bring the TT to the fore in the tuning world, as we seem to be left behind in certain circles..well, the V6 TT anyway..well, thats about to change.

With regards to cost and setbacks..who gives a f.ck its all about the journey.
The sweet tastes sweeter, the more sour its been.

Oh..by the way, Janice is fine and is sat waiting in a car park for me, for when i return to dry land next week and she will be driven 300 miles home..trouble free..

Lonely Steve

Notes from a small 371bhp but oh so happy BT boy...

I think some points Mark makes are very valid I do think that one or two of the BT boys have chosen badly with their builder and are "still" paying the price (literally) but that's their fault ultimately for choosing badly.

You cannot really compare the bigger builds especially Frase's and Steve's and I can understand why he bit at that comment.

You just have to look at the likes of the real BT builds done by Caney, VSpurs, Lego, Storms V6 etc etc and look in absolute awe at what they have achieved

But to dismiss the idea just because of a few issues is crazy nothing has given me more pleasure in 26 years of driving then the few grand I spent at The TT Shop a little while ago.

I thank the "groundbreaking" people that went before and enabled me to sit down discuss a mild BT conversion and three weeks later pick my car up snarling and making me smile like I have never smiled before, 0-60 4.7 secs pulling like a greyhound on speed to the red line with big smiles all the way.

Kamilla eats prob 98% of cars on the road and makes me smile and buzz every time I drive her.

If you want to play safe and sound then of course a BT isn't for you but your life might also be a little bit too safe and sound in my view, live a little or one day you might be thinking if only I'd done this and that I might have had a little bit more fun. Feel the Trainspotting speech coming on.... Choose Life

So kudos to all the BT boys who gave me advice and to The TT Shop for delivering what they promised (and more) almost off the shelf and to the timescale set.

To the doubters live a little life is far too short.

I wouldn't go for the kind of power like VSPURS and others have (can't justify the expense more than anything else) but I do believe there's a middle ground where around 270-300 bhp is perfectly possible, and at a reasonable cost, have a reliable TT with reasonable power. And rather drive a TT than a Porsche really ;-)

But I do follow the BT threads with interest. It's nice to follow the choices that others made when evaluating possible mods (big brakes here more than anything else). I do seem them as portraying hurdles more than stating that BT TT's are unreliable.
 
#23 ·
I think that it says a lot about the progress that has been made with the development of the BT Builds now as when I first started there was an effort from many to join the 300 Club as there were only just a few!

How this has changed now, with the price of the car being so much cheaper and the development costs for a BT GT28 build being more reliable we are beginning to see quite a few people achieving over 300 very easily and cost effectively!
 
#24 ·
Nobody in their right mind would by a TT if they used their heads! People buy it from the heart for reasons as simple as the love of its shape to a complicated as the whole package it comes as but its still mass produced to be average to accommodate the majority of jump in and drive owners.

The real passionate ones cant let go of the appeal the whole package offers so embark on the upgrade and aftermarket options to take it further than Audi wanted to bother with.

What you see is the individual experiences of those that have mostly learnt the hard way that the love of the car and enthusiasm to make it faster than it is full of pitfalls which are often down to a mix of component choice, quality of parts, installation and mapping, ultimately driven by a price point.

The other pitfall is in the level of attention to detail by all the fully trained , Audi qualified VAG specialist technicians you put faith into to do the work. How about 9 out 10 of those still kindly leave you coolant returns rubbing your brake feeds after a cambelt change. Some of the guys putting things together think its all bolt and go, they don't quite think about the consequences of hardware they are fitting and what it may effect.

On top of that you want to take 110bhp 1.8 technology from the 70's and push it to over 400+ along with its surrounding components and stick to the original service schedule then be reliable then you are fooling yourself. start pushing big power then you must drive with some mechanical sympathy and take a more sensible approach to servicing.

If you wanted to get it done properly then you need to find a happy medium that takes all the above into account.

You want some recommendations.... email me!

All I can say is thanks to the BT guys for pushing there cars into super/ hyper car performance territory 8) and for giving us a warts n all insight
I have been in MattB BT car and that was awesome :eek: so I just can't for the life of me get my head around what Steve vspur car is like
If I had gone down the BT route with the QS ( it was so close and it was Linda pushing me to do it also 8) ) I would have gone down the ttshop route, a tried and tested reliable power hike, and I hope one day little shag takes me for a spin :p :p :p

I love all the build threads, I find them fascinating - educational, emotional (!), but most of all I'm glad that even with c&cc mag gone, everyone is still up to the same old mischief!

If I was going to spend I would get something like a MEV Sonic7 as my project. Squeeze 400hp out of a kit like that and you are getting close to a formula ford experience on the road!

But of course Sonic7 is (and I better whisper this here) a zetec kit. If ONLY it was a VAG build with DSG oh yes my lord, that would be simply divine.

But more power to the big turbo brigade - life is boring - make it your own!!!!!
