Sorry. No offense. Since it is a 4A-GZE engine, I thought he would have better luck there. Celica doesn't use supercharger (well, at least in stock form). I just think the resources is limited here. I apologize for any rudness.
anyhow, an engine is an engine.....so the same stuff aplies to all of them... I found out my mr2 needed a rebuild...so I droped the engine, and did some research... I pulled it down to the block and stuffed it full of forged pistons, carrillo rods for a 1.8 liter, and a 1.8 liter crank. I also used pistons with a higher wrist pin height
I built me a toyota stroker motor... I got my head reworked, intake & Exhaust port polished, intake manifold extrude honed, and the stock manifold replaced with a header. I will be running a k&n cone filter, along with an msd blaster 2 coil and magacore wires....
I'm just amazed @ the parts the make for this thing....its so awesome.
a supercharger is gonna be almost the same as a turbo as far as bang for the buck mods, the best and easiest way to get it done will be good intake, exhast, and ingition. those together will spare you a decient amount of hp, well who doesnt know that..lol just wanted to post again. hehe
The Mr2 is complete, and broken in...I got my new interior in, my sound system in and the engine is all done
Here is the route I chose to go with it.
Forged Wiseco pistons
Total Seal rings
Full Port Polish from throttle body to head to the exhaust manifold
Accel Supercoil with MSD wires
Supercharger Rebuild with/HKS pulley to make it build more boost earlier
15degree btdc timing
Stainless steel intake plumbing, with K&N cone filter Routed to bottom of engine compartment
HKS Catback exhaust
Celica (5S-FE) injectors swiped from my old motor
Ford Mustang GT airflow meter that Wynne Speed modified to fit
Billet Fuel Rail, and Supra Fuel pump
Its broken in and has made about 3 passes
Ran a 13.68 on premium gasoline and Toyo T1 Tires
