I'm thinking about upgrading the turbo. I have a 95 3sgte motor with the ct20. Any suggestions? I'm looking at the garrett gt28 or maybe the stage 1 or 2 ct20. All my internals are stock for now. I figure if I upgraded the turbo I'd keep the boost low until other mods where made.

dont bother with ct-series based upgrades.
unless they are machining the exhaust housing, like ATS does with the ct-27, compressor side upgrades are pretty much usless, youll loose alot of spool, and not gain much HP.
what are your goals for the car?

I'm looking for around 300.

GT28RS. Look into the Speed-Source.net upgrade kit, it's good quality and you can probably still use the W2A IC if you still have it.

I took a look at that kit and it looks pretty good Thanks for your help. Anyone else use this kit or know anything about it?

jgreening had the prototype for the gt-28rs kit by speedsource.
it is IMO by FAR, the best '28 kit on the market.
IIRC j made ~270-80whp @~17 or somthing PSI.

I better start saving then Thanks for all your help guys.

It's the kit I would get if I was going to get a bigger turbo.

I too am, in this proyect , I would replace my CT20b for a GT28R, the question is also a need to exhaust manifold? or just a matter of replacing turbo

and saw this site,
