HIPSI Stage 2.5 Engine

Return Back Home

This is my 2nd version of my AE92 Supercharged 1.6l 4A-GZE Toyota Engine with major intake changes.
The Engine is retired and hence this page will never be updated; so ends the Stage 2 and 2.5 Engine.

Original (1983-1989) 112 HP American 4A-GE engine removed and replaced with a JDM (1989-1993) 4A-GZE Supercharged Engine.
I have not Dyno'd it yet, but I believe it is producing around an estimated280 HP.
280 HP / 1.6 L = 175 HP per Liter.
2350 Lb car / 280 HP Engine = 8.4 Weight to HP ratio.

I have rebuilt the entire engine and completly redid 100% of the air intake routing. I moved the throttle body below the intake, running an 11% larger throttle body, 20% larger piping throughout, 20% larger supercharger, and a Normally Aspirated Intake manifold that out flows the Supercharged manifold maybe 2 to 1.
I also created an adjustable Boost Control Valve using a 3/4" water pipe Boost Return/Supercharger bypass system I fabricated. With it turned all the way on, Max Boost is 2 PSI. With it turned all the way off, max Boost is 17.5 PSI. Awesome. Just Awesome. I have totally reworked and redesigned so many aspects to the original engine.

The results are incredible to say the least.
