Should I go with the GT42R or a T88 turbo for my future planned 20bt? I'll have a large streetport and Haltech.

 

depends on youre horse power goals and what the car is going to be used for drag/track/street, GT42R from what i understand is a great turbo , i have no personal experience with it though , and which T88 are you referring to the Greddy (mitsu) turbo or the netics/garret turbo?

 

I have the GT42R, if you can afford it, do it.

 

first save your $$$ til the car is about done. Trust me, youll probably need it for the 20b setup

 

worry about the exhaust manifold, turbo and WG last - get the engine in, fabricate everything else, hook up gauges, wiring, etc, than worry about that.
