Hello all, i would like to ask about exhaust housings from t34,so which is the best choice for 1.9bar peak and 1.5bar hold (about 350-370hp)with greens injectors, the .48 or .55 exhaust housing?also the .55 does it fit on T3? thanks a lot

You can get a .48, .55 and .63 turbine housing to fit the T34.
I would personally use a .48, you will get the power you want from this, but almost defo not on greens though, the smaller .48 will give the least lag, and makes a really nice road car.

You sure Tab, a .48 at nearly 2bar of boost? It'll be screaming its knackers off.....personaly at that sort of boost I think I'd be looking at greys (if keeping it old skool) and a .63.

I've driven all three housings.

Out of the three obviously the .48 spooled up quickest. That was on my old cossie running 350bhp (car was on greys)..was a really nice punchy set up for a road car.

My mate has the .55 on his (siemens blacks) and that too is a really nice punchy set up, slightly more lag but pulls harder when on boost.

My car is runing the .63 (again siemens blacks) and it is really quite laggy...HOWEVER it pulls like a train when it comes on boost!..only problem is it doesnt make it's full 2.2bar until over 4.5k rpm

I'd say the best comprimise between the three is the .55 with siemens blacks. My mates car is running 360bhp on that set up..cant remember exactly but I think he's running 1.7bar

Hope this helps

my old one cossie was on a t34.55 @ 2 bar off boost and siemens blacks, very very good road car.

been in 2 other saff's with a t34.48 and they ran out of puff top end.

you will need either grey injectors or siemens blacks, i wouldnt risk greens personally

i want to ran the car as it is with greens,and the same chip,so i'm wondering which of both housings work better with the same bar boost and greens!!

English

If you change the turbo, you will need to change the chip

You are best to change the injectors at the same time so if you want more power later, you can use the same injectors

Do it all at once. Do it right.

Saves money in the long run

if you want to keep greens then its got to be a t34.48

i am currently in this dilemma, however, i think im going to fit a GT28 to overcome this, along with a 4x4 exhaust manifold

I had a T34.48 on Greys NMS Live map on my old 3dr and it was superb as a raod car as people call it, very punchy did ease off at the top end.

My car is now with Karl having alot of work done to it which includes a new TT T34.63 with Siemens etc etc so i'll let you know how it feels..

Quite lively i'd imagine with 2.2bar peak up it's ass.....

Hi Andy,

Yes it's gone now mate, the Gunship on the T3 is/was superb don't get me wrong, but the lack of grunt/power after 6k is so noticable mate and tbh running it @ 27psi i don't think it had long left...

I'm looking forward to my drive home next week though...

I didn't see the greens refference, but as said will need higher flowing injectors, and a complete new chip to suit injectors and turbo sizes if changed from current spec.
380 is no problem from a T34 .48, CR turbo's even ran this set up on his 2wd sapphy.
