Upgrade CT-26 or New Turbo

MK3Turbo · 06-04-2005, 06:13 PM

I have a sweet '89 Supra with a bad turbo. I've done a lot of work on the motor and seeking advice on which way I should go with the turbo... specifically, should I upgrade the CT-26 (rework the housing and larger compressor) or go with a completely new turbo?

This is a daily driver, but I've done the following to the 7MGTE:
- HKS 2mm MHG
- Ported and polished head
- ARP head and rod bolts
- JE pistons
- 3" downpipe and exhaust
- Apexi intake.

I'd like to take advantage of this motor, but I don't want to get silly (keep it a fun, daily driver). I plan to upgrade the fuel system (Lexus AFM + 550 injectors) and stop there. I'd like to preserve the stock manifold/downpipe configuration, if possible, but willing to upgrade if necessary.

Various companies say their upgraded CT-26 turbos (stage 2 / 3) offer outputs of 450 to 600hp. Realistic? (I hear 350 is max). Should I waste my time with an upgraded CT-26?

**What is the best option for the car? A new turbo?

Thanks for your professional advice!!
