Hi JR, I too am interested in this conversion to a 99 TS - It has been done by an E European Indi - on Youtube (being driven).
So far all I have managed to get is hearsay ranging from ..you need to change so much it is not worth it ....to same floorpan, minor mods to eng mnts only...
I would have thought a cheap indi engine management ECU found in kitcar mag and race mags for c £200, custom half shaft mods, custom free flow exhaust + swap in complete 20vt with trick diff and box as a unit (clearance issues?)
Perhaps we can track down a suitable skilled enthusiast mechanic to carry this out - sharing 'development' cost will make it more attractive - sure we can source a pair of 20vt and have 'Flea' or similar check them over and tune to 340bhp (safe limit for std internals) - he has new super quick trick turbo unit and is one of the best for mapping them - he could no doubt source appropriate ECU and make interconnect harness to talk to Alfa system (not as if either are DBus!)
Really rather keen to do this if you are - where exactly are you, I am Corby Northants area - may be able to offer garage space to work on the 2 cars side by side if that helps keep mechanic cost down
This would have to be done on a very tight financial leash to reduce any potential non recoverable costs when sold - I would have thought: £500 for engine and box, £1k for turbo upgrade, ECU, map and used intercooler, £500 custom exhaust system, £400 eng mnts, gearshift + drive shaft mods..plus a negotiated private project cash labour rate based on doing 2 near identical cars (perhaps c £1000 / car?) - on top of this would be new discs and calipers plus suspension check / overhaul...already over £4k.... (£500 could be saved if a pre tuned engine in fair condition is sourced?) - without hidden costs it is already a little alarming as over half of that money wouldnt be seen again --- can you see a way of getting it done for less? D
Several people on alfa155.org have these engines in 155s, which is essentially the same underbonnet layout - could be worth having a check on there.....One of the guys who has done it is East Midland based.....Alfachris......
...i like the fiat coop too, however I prefer the GTV and...i like the 5 cylinder warble + turbo rush - If I find the right V6 GTV first I may indeed go the simpler route as power is no longer everything to me
I think the V6 Alfa engine sounds better than the Coupe engine, but overall the coupe was the better car.
The only thing is lacked was the Alfa badge.
The Coupe was more reliable (No exploding diffs), faster, easier to tune, more economical, had more room inside and was cheaper to buy new. I also prefer the Coupe seats and interior (Proper set of gauges including oil temp and pressure) and the seats were far more comfortable.
The simpler rear suspension made little difference in the real world to handling and gave the car much better practicality and made it cheaper to repair.
Styling wise both looked great, obviously some will prefer one, others the other.
I have had two V6 GTV's a 16V Turbo Coupe and a 20V Turbo.
All were great cars, but the Coupe has the fondest memories.
symon....dont talk me back into a 20vt coop...was always worried about rust which seemed far more prevalent on the Fiat...otherwise I agree with what you are saying.. - if someone was to underwrite a 20vt to be in excellent health, I would go to £2.5k (many half decent ones go at a quarter of this) - one clun car I missed was asking £400 and was 300bhp with plenty of work done...and in my favourite colour....darn it!
Only recently learned why so many Q2 conversions - thought it was strange so many considered spending over a 1/3rd of car value on an alternative diff was a good idea!
Sure I shall be delighted with either a 20vt or v6 that has been well sorted
Have to say I just cant stop oggling my silver ts gtv + red momo.....
