My MR2 Project

[Mike Lowrey]

why not use an AFC for anything under 300whp? ive never seen a problem with them on other cars.

anything over 275-300, id gop straight to a powerFC or AEM

The stock ECU will add lots of timing when you tweak the tune via the SAFC. There have been a few successes, but many, many bad endings.

My path to what he is looking for, power wise is:

ATS CT27 Turbo
ATS Cam Gears
ATS ROM Tuned ECU
ATS Bored out fuel rail
ATS modified fuel pressure regulator
HKS 264/256 Cams
KO Racing TKO 2.5" Exhaust w/7" Cans
KO Racing DP
Blitz SBC-iD Boost Controller
Apex-i Intake
SPEC Stage II Clutch

Dyno'd @ 260 rwhp (90 degrees air temp) @ 15 psi

I had an ST205 A2W IC ready to install, and was planning on running at 17 psi which was expected to yield ~280rwhp.


This would be a safe and reliable setup.


Do it right. Don't use SAFC.
