Will this work???

[Squizz]

Can you take an SR20 Turbo, swap the rear housing with a GTR one and bolt it back onto a GTR.

Obviously for both turbos, before someone says something silly.

Thanks.

[Squizz]

Surely I'm not the only tight-ass aorund here, someone must know something...

[sproosy]

That would just be like having 2 T28's wouldnt it?

[Squizz]

Yeah with steel wheels instead of ceramic...

[sproosy]

I cant see why not......... Sounds like a good cheap upgrade!

[Abo Bob]

So are you saying the SR20 turbo has a steel exhaust wheel?

[Beer Baron]

Yeah with steel wheels instead of ceramic...

umm, no.

the SR20 exhaust housings have a different flange. (they are T25, GTRs are T3).

aslo, how will swapping housings affect what wheel is on there? the exhaust wheel and compressor wheel are FIXED to a common shaft. replaceing the housings wont do f**k all about that. the ceramic wheel is bonded to the shaft and would be hard to remove in your back yard without the right tools and know how. then once you've done that and want to put your new wheel on you then have to somehow be able to spin it up to 100 000rpm (or some such) so you can balance it.

bottom line? not feasible. sorry.

better and probably cheaper to go to somewhere like GCG and have them rebuild your GTR turbos with steel wheels.

GTR's are not T3.

I am wanting to keep the GTR exhaust housing and mate it to the SR20 carriage and front half. So yes swapping the housing will fix the problem as I'm basically using an SR20 turbo with a GTR exhaust housing.

A bit clearer?

hmm, it seems i am as stupid as I look.

I read it the other way around.

yeah, should work ok. just gotta find 2 S15 turbos then.

BTW, I wasn't trying to say that GTR turbos are T3s I was saying that they flanges are a T3 type flange. maybe I got the number wrong but point is turbos for SR20 and turbos for GTR have different flanges where they bolt to the manifold. won't affect your plan though as you are going to use GTR exhaust housing.

go for it.

And I am saying that they are not. RB20/25/30 are all T3 Flange, GTR's are different. GTR's have the T25/28 exhaust flange.
