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 think if you're in any sense a car enthusiast then you are gonna want to tinker with it, make it better than stock and generally put together a car that stimulates the senses and puts a smile on your face. In the case of the TT that can be as simple as sorting the suspension, steering, brakes and remapping it.

For many that is all they need or as in my case all they can afford (certainly at the moment). There have been times - specifically after I first drove Sam's car at Ace and then Wak's over at Staines that I have followed the threads to try and discover the route to reliability and big turbo thrills. Sadly, or fortunately, dependent on your viewpoint, I never did take the plunge and commit to doing it.

In retrospect had I done so, I'd probably be in a position now where my car needed big money spent on it to keep it running well, whereas (touch-wood) I have a reliable mode of transport that has cost me very little in the past year and yet still delivers enough punch and fun to make ownership a pleasure - after some five years or so.

But hats off to those who have and will commit great swathes of cash to push the boundaries. There can be nothing quite like extracting ridiculously high performance figures out of a car that was never built for it.

Especially if that is done against what is generally considered superior machinery out on the open road. 8)

Cheers

rich :p

Mines definately not a case of more money than sense, I've been toyin/saving with the idea for a few months and tbh it was my mum recently passing away suddenly that made me think... F*#K IT! Your only here once n if u wanna give it a go do it! :)
Even If it turns out to be a "bad idea" then at least I can say I done it. :D

And thankyou for ur gd luck! :)
 
#30 ·
Sorry about your Mum :(

No way its a bad idea as long as you know what you are getting into and go down a recognised route. You will end up with a great reasonably powerful reliable TT. Result ;)

Pity you didn't turn up to the RR day it was fun

Thankyou!

Yeah that's what I'm goin for!
Like it has been said, there's plenty to learn from cause of others leading the way.

Yeah woulda been a good day but I was so unorganised that day plus my TT looked brown instead of black where I'd neglected it the past few rainy days lol
Didnt wanna get shown up with all the spanking clean ones haha
U run urs?

Its all down to genetics, and mans desire to be better , faster and stronger than the next man.

The financial commitment to a BT build does put many of us off, coupled with fuel prices there is no economic sense in it.. ( for the average person).. Are these builds carried out because its economically sensible.. are they hell... If they were you would see threads such as - " ECO BUILD THREAD "- Big Eco Build...90MPG...

Frase, Steve and others obviously have the funds and a lifestyle to be able to commit to such projects. Its their cash and time and we as forum users benefit from the interesting build threads.. its like watching a film.. we want to see the end... Do these builds affect our lives..? - no they dont.. is it our money?- no.. most people have hobbies.. I have friends who spend thousands on Hangliders, fishing tackle, building projects, extentions etc..

There are no doubt forum members who are jealous, there are members who become annoyed at arrogant attitudes.. - there are the members who find it amusing when something goes wrong... There are probably members who are no doubt put off at the constant problems, delays , snags, and finally members who watch in detail as the build progress, with intentions of emulating the BHP, or going further..

Would Frase or Steve ever itemise their outlay of cash on the forum inc parts and labour? I very much doubt it.. Just like a gambler would not admit his or her losses.

Would I start a big turbo build thread... no. I would not want the added pressure of forum vultures looking over the pictures , and revelling in misfortune. I would post when the project was complete.. but each to their own on that front.

I think in some circumstances the abuse on build threads spurs the builder on to get it right / and prove the abuser wrong...
For me if i wanted a penis extension , I would save up for surgery.., or invest in an R1 bike.

I too take my hat off to the people pushing the BT boundaries, modding certainly with my own experience is that it's like a drug and you continue to feed your habit - as have said before sometimes I wish I'd just stayed with a Stage 2 and Forge DV but am way past the point of no return now, will I go BT? Maybe, maybe not - if/when my KO4 dies I'll take a view, in the meantime I'll keep strangling the life out of it and read in awe at the build threads of the moment that slowly make their way to our little forum!

Slow burner BT build 15k

Rebuild cost after I over boosted Janice 6k

Total BT cost to date 21k

This doesn't cover suspension, brakes and other non engine related mods.

I think my costs are pretty cheap compared to what Frase has paid but my build was always going to be a long one, where as a quicker build will always command a higher invoice.

I love reading the BT threads and people's ideas.

I went from a mildy tuned TT (280bhp) to a 340bhp Z4M and was bored quite quickly. I miss the tatting so I guess that says something.

Just to follw this post up:

neilc said:
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.

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

How do you make a Mk1 TT handle like a 997 turbo or an Elise?

Having had all the major handling modifications on my TT I would have to disagree in every single way. lol

Power yes
Stopping Yes (ish)
Handling (Sorry but not a chance in hell)
The TT is nearly twice the weight of an elise/Vx. And the 997 is in another league again.

Just the discussion I was hoping for. But don't those build costs just make your eyes water? Have to admire your commitment to the cause!

Of course I understand the enjoyment you get out of the process; the sense of challenge and the achievement of completing a project that has pushed the boundaries and exceeded expectations. It's a creative process and like any other has value in its own right. But I guess at times it looks like a process that can never end. When people talk about doing 3 BT builds on one car - three! - before getting something they are happy with it does make you wonder whether people are actually chasing an impossible dream. Steve and Fraser will be driving their cars soon enough but I wonder if they will ever be satisfied?

And now even VSPURS is up for sale - possibly the most succesful BT build ever done. We're told it is being sold to fund another TT project, so it seems even perfecting the job isn't enough! It's been described as an addiction and I think that sums it up. It certainly costs as much as a decent heroin habit! :)

So anyway, much has been said about how these pioneering builds add to the collective knowledge so do you think we can reach a concensus? What does the Forum collective suggest would be the perfect BT conversion?

Let's presume we're not wanting to push the boundaries and make the most powerful TT there's ever been. Let's say we're going for a balance of power with reliability - a Porsche-beater that you can drive every day with confidence and still manage to find insurance for. I'm guessing something between 350 and 375 bhp? Exactly what parts would you use and where would you get it done, to be sure it was done in a fixed cost and they got it right first time. And how much would it cost, all in?

Suggestions?

Interesting thread.
I have done the modding thing with my old TT and took it from boggo 2000 plate silver TT to full on stage 2 spec car. Bought the car about 5 years ago for 11500 and had receipts for over 10K in mods and maintenance (a lot of both). Sold the car with 130K on it to my good mate Lee (L33JSA) for a bargain price - (you know thats true buddy).

I had been looking into big turbo for a long long time, I have emails from my enquiries 3 years ago from Backdraft, Jabba, Badger etc, but never really had the spare cash to chuck it all at the car, plus none of the above are anywhere near me in West Lancashire. There was always something else to spend the money on, you know how it goes, house, extension, nice holidays, other car, two kids blah blah blah blah. I also have a 50 mile daily commute and didnt really want to lose the car for a number of months. I really had wanted to keep my car and big turbo it but it had 130K on the clock and it seemed to be a gamble.

Then the BD car came up for sale at 12500 and it just made sense to buy it. I could keep the other one for a bit and swap over the bits I had that would start to make the car feel like my own. I will be honest for about 6 months it didnt feel like mine.
Lee and myself swapped over the interior from the old one, my stereo system speakers, amp etc (carefully ripping out every inch of the bose install), rear lights, wheels, defcons (Lee), rear brake conversion(Lee) exhaust system(Lee), lights, orbit ring, big nob, was number plate lights etc. Again it didnt really feel like my car.
Then I started adding some more bits and pieces of my own, water meth system, cf rear spoiler and more recently revamped front end, V6 bumper, sprayed grilles, painted inserts, tinted corners etc.
The trouble Mark referenced was two fold really, some electrical problems (fried wiring loom) and the death of the turbo. Now these things have been a problem, but I think during the act of helping Lee to put them right I have really bonded with the car.
A new turbo was 799 +VAT but I opted for a WRC bearing housing upgrade and a uprated heatshield which added 150 +VAT to the cost (original failure due to excessive heat so well worth it), came in a touch under 1200 quid in my hand. Coil pack harness about 28 quid (20 quid for a pin removal tool, but to be fair hammered flat and dremmeled paper clips are the tool of choice) Oil pressure gauge around 150 quid, Gaskets, nuts bolts etc about 50 quid, Oil Filter, Power steering fluid, coolant and a regas of the air con about another 120 or so, and about three weekends of really hard work and the car is back.
Went to Lee's tonight for a little tweak to the exhaust position, a fluid check and some logging and came back with a massive grin on my face. Adding my own mods had helped me to "bond" with the car and I was especially proud of the new front end, but these last few weeks I have got really intimate with the car, I am really proud of what we have achieved and I now have a fully working car and its been well under two grand for the repair. Obviously not everyone has a friend with the skills and patience of Lee, and I am very fortunate that this has worked out this way.

Anyway thats a long way of saying - Big Turbo - Hell Yeah, its the only way to travel :) :-*Anyone looking at Steves car should realise that you will never get a cheaper way of getting into this type of car. Go for it :)

Just read the whole thread :roll: if you want to keep your tt reliable but fast then keep it at circa 350bhp for sure,my old jabba set up was awesome and the ihi turbo used to spool very similar to a Ko4! I have spent about 25k on my car over a period of 9 years so just under 3k a year so buying a 50k+ sports car is out of my reach anyway :) i could of sold my tt countless times and have had good offers for it but i can't let go [smiley=bigcry.gif]

I sum it up for myself as: "Everybody needs a hobby." My hobby is this TT . . . has been for 10 years. Bought it new, special ordered. With what I've paid over the years, I could have bought a number of other special cars . . . but what's the fun in that? 1st, I'm an Audiphile. Had a Cabrio for a number of years and kept it like it just rolled off the factory floor. Only reason I parted with it is Freeman Thomas' TT! Saw the prototype, fell in love with it. Secretary bought me the Maisto model of it. 2nd, I don't like Porsche's, never have. They all look like Schuco wind-ups to me. May handle well, but design-wise I think they are uninspired and resting on their laurels. Third . . . I love to tinker, make stuff, change stuff, adapt stuff, make it personal, etc. This car has been one big tinker-toy set for me. I'm not a professional mechanic, so some stuff I've had to simply pay to have done. But . . . I've been a lot more hands on than simply asking a dealership to give me a completed car for xx sum of money. This car (and the project aspect of it) has provided me countless numbers of hours of fun, satisfaction (and yes, some aggravation . . . but without skin in the game, what's the thrill? Jumping out of a plane when it's on the ground is one thing . . . jumping out when it's aloft is another. Aggravation, believe it or not, sometimes defines the level of satisfaction when it does in fact work.) And this car offers me different levels of activity . . . I can challenge myself, take the risk, and pull the front end off, pull apart the dash, changing whatever . . . or, I can play it safe on a quiet weekend and simply condition the leather, or polish some aluminum, or . . .well, you get the picture I think. For me, it is a hobby.

Build time total is est at 3 weeks but i have told them i will be back in 5.. Lets see.
I have faith in these guys as they do work for the other tuning guys incl Awesome and Storm, so lets see if they can produce the goods first time.
What do they have to loose apart from their rep, as everyone knows thats what generates sales.. :roll:
Steve
What are you saying Stevie it doesn't make any sense...

ÂŁ21k compared to ÂŁ13k how is that pretty cheap ?

I'm confused what happened to the ÂŁ45k you were talking about at the RR meet ?

Costs are relative to each owner, what might seem expensive to you, might not be to the next person.
Someone else might well think, "damn I'd rather spend that money on boats n hoes" or as said might consider it a hobby.

It's been a great discussion to see both perspectives, and I still can't make my mind up. I'm a relative noob when it comes to cars as hobbies.

I still can't decide on whether I'm gonna keep my car and spend the time & money on it to get it to either the 350 or 500bhp mark, plus additional aesthetics or just be lazy and buy the porsche; not my 1st choice, next car would then be either rs4/6 or m6, with minor upgrades and rest on running costs.

If I keep her and start, there's no going back for me, its all or nothing so it's not a decision I can make lightly.

Your right, it is a bit of an addiction, as anything that you enjoy doing in life, you'll want to do it again.
As you say, mine has been successful but taken a lot of development to get it that way and to a degree I think I've got it finished to a point that I don't want to be making wholesale changes to it in case they don't work messing up the cars current power and reliability.

I have however, during the development of this car come up with, and identified, other ideas that I'm not willing to try with this car as it could be even more expense and have no guarantee to work, so I'm going to buy another one and start again on a way that hasn't yet been tried along with a few other mods that as yet haven't made their way onto a BT TT build. By selling this one, I'd be able to make rapid progress with this new project but by keeping it I'm not going to help my addiction as I'm not wanting to make further big changes to it!

It can sit in the garage and come out every now and again as it does at the moment but my thoughts were that if I could get a level of cash for it that would give me a focus on doing something else then why not! I've certainly had huge amounts of fun in the car from Santa Pod to Stelvio it's been a blast. So let's do it all again!

Ok, I'm an addict! Lol! :lol:
