Turbo ST?

[SR5_GT-s]

Hey all, i just got myself a 1991 celica ST, and im thinking about turbocharging it. yes i know the 4afe isnt the greatest motor to turbo charge but i dont want to have to drop a new engine in it, ive been doing some research and so far i know i will need 4agze pistons and rods, as well as some heavier valve springs. while i have the engine torn apart im going all out with new brarings on everything and new gaskets and seals. im going to get a remanufactured 4afe head and painted valve cover. as well as some ARP head studs to handle the boost pressure, so heres a list of everything and i want to know if thers annything im missing or anny advice on turbo charging this car

-ARP head studs
-4AGZE pistons and rods
-aluminium head gasket
-4agze valve springs
-stainless valves (most likely manly)
-porting?

so thats what im going to do for internals to handle the boost, is ther annything else i need mechanically to turbo the engine? everything else like engine management i figure ill go with a programable AEM computer or something, or can i use the 4agze computer? anny feedback will be of great help to me, i cant wait to get this build underway!

Fuel enhancement via larger injectors, fuel pump and FPR. An intercooler system.
A stage 2 clutch to handle the increased HP and torque.You will not be able to use the stock ECU. Engine management of some type will be neccessary.
What are your HP goals?

yeah, i was thinking a SXT stage 2 clutch, and if i remember right the injectors are denso body, so to spool a T3 would be arround 500 ish cc injectors? and im looking to get arround 300HP

[MR2Jedi]

500cc could get you to 300hp. The T3/T4 runs out of breath at around 340-350hp.

so what about the 4agze internals? are they close enough to the stock 4afe internals that they could be bolted right in? or would i need to machine annything down or get a different crank? larger/smaller head gasket?

Not familiar with that engine, just turbocharging. Hopefully, someone else will chime in with those details.
