Question on stock style O2 housing and changing turbo's

[ssdragon]

Well, I'm ordering the VRS SS Turboback exhaust with the 3 inch o2housing that matches up to the stock turbo. I definitely plan on changing the turbo in the future but not soon. My question is, if i'm shooting for 400whp on a gsx, is there a turbo that is good that will bolt up to a stock style O2 housing? I prefer garrett ball bearing turbo's but if another is recommended then I will consider it.

I don't mind changing the manifold to fit it either but I want to retain the VRS O2 housing.

Thanks.

one option is the mitsu evo 3 16g thats not a bad turbo and it does not take too long to spool

can that turbo make the 400whp on a 97 gsx though? I thought pushing a 16g that high was not the best move?

I would go 20g then port a 2g o2 housing. Sorry I see you have the vrs o2, that would probably be better.

 

[ssdragon]

thats what i mean, with the vrs o2 housing its a stock fitting piece, so a 20g would fit on it?

All Mitsubishi exhaust housings have the same bolt pattern. I don't see any reason why it won't fit.

Any turbo with a mitsubishi flanged turbine housing should fit, the exceptions being the FP 30 series turbos, which come with a V-band outlet. Also, the Evo III can make 400 whp, but will it be easy? No, not really, I think if you want an easier 400 whp you should look into the 50 trim, the 20g variants, pretty much any turbo that flows a bit over 40 lb/min should meet your goals.

If you want a turbo that's capable of 400whp and is BB i would go with the PTE SC5031RE. It will bolt right up.

thanks for the good info. With the turbos mentioned, I have to change the exhaust manifold to use them right? Or is there an adapter kit?

 

[dsmconvict]

Nope they will bolt right up to the stock mani.

sounds good, 20g isnt ball bearing but might be the way to go for simplicty and cost. I havent checked that other ball bearing turbo out yet that was mentioned but ill give it a look
