Right there must be a way to fit a turbo to my GTV without it costing £5000 and I really like the idea of fitting a turbo and not a supercharger !

Now it occurs to me that there of course 2.0 V6 Turbo's knocking around in Europe so why could i not pick up one of the turbos off 1 of those and fit that to my car ?

Would love to hear from you all on the pros cons and hows this can be done !!

Les see if between us all we can up with a good plan :)

thanks all

the v6 2.0 is a single turbo after a long length of manifold.

you would be better off with two smaller turbos if there is room for them.

Without major engine mods you wouldn't be able to run much boost...

So why not look at supercharging?

Yo Franky! You getting greedy for power? Me too! Remap was good and still is but when is enough actually enough? NEVER *evil laugh!!!!*

When I saw the title of your thread I automatically thought "this guy as 5k burning a whole in his pocket ... good luck on your search ...

What knowledge and experience do you have regarding forced induction? If it is limited then unfortunately it will cost over 5k. Buy a car with a turbo already fitted.

You dont approve Chris?:lol:

I will say Franky its not worth doing things on the cheap though. I am no expert but all that extra boost, bhp and torque would surely blow something.

Your going to have to lower the compression ration if you want a meaningful power gain. Then sort out the fuelling so it doesnt lean out and melt everything.
But before all that you need to plumb a turbo in to be fed by both banks - not easy. A 2.0 V6 turbo would give some good hints but they are rare over here. Then you would need some very nifty plumbing of custom pipes to get it back round and up to the inlet.

All in all, spend £5K when you have it or it will be a long expensive process with no back up :(


Sorry to hijack: @ Chris, could you have a look at my thread in the 164/166 tech lounge, got a feeling you will have some advice to give ;)

OK, you'll not get what you spend on doing this back.

It would seem likely that the 2 litre V6 used in the turbo has some differences before being turbo'd - lower compression ratio, sodium filled valves etc.

What about getting a turbo'd V6 engine from the continent and after modding and cambelting that drop it into your GTV. There must be loads of stuff on European forums on tweaking the 2 litre turbo?

Will anything foul the RHD steering gear? GT-R only ever been RHD, a LHD version would have fouled the turbos.

Fiat 20V Turbo it, but symonh2000 tells me Fiat driveshafts don't mate to Alfa hubs, or perhaps it's 'do-able' in the GTV, where it isn't in the 156 as both the Fiat Coupe and GTV have Macpherson strut front suspension?

The easiest route would be to get a Fiat Coupe tweaked like symonh2000's.

That has Poooooooowwwweeeerrrr

I thought the 156 and Fiat Coupe 6sp shared gearboxes...

Anyway, dropping a 2.0 V6 TB in to a 3.0 V6 car means he is already about 20-30bhp down, it will need a better chip to get it back up to the same power output but with the beautiful drivability of a NA Alfa V6 gone...and then aftermarket turbo time, stronger head gasket, new map for the ecu....lots of potential if the engine can take it :D

How do they make the capacity difference between the 2.0 V6 turbo and the 3L? I assume it is bore rather than stroke? Just wondering whether it would be easier to get a 2.0 turbo and put a different crank on, than try to turbocharge a 3.0? Also need to think about turbo size, a 3.0 will put out 50% more flow than a 2.0, so the turbo probably isn't big enough........

is the compression ratio really much of an issue? - as the 3.2 can run some boost ok and it has a higher ratio than the 3.0

Hehe i thought this might raise a few results :)

Its nice to see that people can give positive answers as well as plain old RUDE ones aswell !!

I love my GTV and dont wish to change it however i do wish for MORE POWER !!!!! MUST HAVE MORE POWER lol

Also i have only seen places doing superchargers for the GTV not turbos so if there are garages ( not autodelta ) that do turbo conversions please list them for me :)

thanks all

With a bit of inginuity and some engineering skill (or some good friends with engineering skills!) you can turbocharge any car, most modern engines can take about 6psi of boost without internal modification, and you should be able to remap the standard ECU to cope with that.

Then again, if you know where to look a set of forged pistons can be bought for around £400 (for a four cylinder), so why stop a 6psi???

You shouldn't need to go mad on upgraded internals unless you are planning on driving it like a hoon all the time. (May be difficult not to!!!)
