Need suggestions on a small turbo for a 998cc 16v twin cam engine. It has to have a t25 flange since The manifold I have is t25 flanged. Looking for fast spooling and around 12 psi max.

What do you guys think of the gt17 off the saabs?

 

It'll probably work good on a 1L engine. Is this a bike?

 

it will spool, not sure how quick depends on your ability to adjust timing or not/ and what comprssion you have, and all that happy ----... but you will have a useable power curve

 

no its not a bike its a nissan micra lol.

its 9.5/1 compression, gonna be only 8 psi so not doing any work on the engine.

What do you mean by adjust timing? I can do it with the emanage piggyback i got (retard,advance)

The turbo I have on it right now is T25 .48 on the compressor side and the gt17 is .53

the part numebr for my old turbo is HC 1202A / 452047 - 15 and the new one 452204-4 gt17 9172123

Can anyone tell me the difference? The t25 I have now gives about 1 psi at 2200 and 5 at 5000 which si crap I am lookign for straight up 8 psi by 3000.

 

any idea which cars have a gt15 that have a t25 flange?

 

Just go pick up a gt12, bike turbo :P

 

go get a rhb5 off of a old 80's subi, or older mazda/ford & make an adapter plate

 

i'm not too sure but isn;t the rhb5 bigger then the gt17? It has the wrong flange as well. My manifold is fitted with a T25 flange.

 

I dont know how big it is but it was at full boost on my d16a6 by 2000 rpms

 

even then I can't use it unless I have an adaptor plate. I actually have an IHI RHB5 from a chrysler voyager as spare but It's impossible to find adaptor plates over here in the u.k
