non turbo performance

i have i 1988 non turbo supra automatic and i dont whant to do an engine turbo swap. i need to know how much horse power i can get out of it and list of parts i can get and where i can get them to make it have that much horse power . thank u

you could probably get at least 500 hp but it wount be easy and be very expensive at least $10,000 i would think. You would have to get new pistons, rods, valves, valve springs, crankshaft, cams, bearings, bored out at least .017, lots of porting, new intake and headers, throttle body, fuel system That might bring you close to 500 on race fuel with about 12 to 1 compresion. if you wan't more than 500hp get a very big shot of NOS with all that it could handel it as long as the rest of the drivetrain can. get rid of the automatic. and it would be alot easier to just get a turbo.
