IS300 Turbo or Super Charger?

[Sluttypatton]

The heat created by turbochargers isn't due to the fact that they are exhaust driven, it is due to the fact that compressing air creates heat. Heat transfer from the exhaust housing is fairly minimal. Superchargers create heat just like turbochargers, just as any compressor creates heat. Also, turbochargers are actually superior in drag racing and would dominate the competition, unfortunately there are numerous rules discriminating against turbocharged drag cars for just this reason. Turbocharged drag cars have a far greater potential since they do not suffer from the effects of parasitic loss of power from the crankshaft. Supercharged drag cars loose a HUGE amount of power to driving the compressor, it really is mind boggling how much they loose.

About stages

actually turbos would beat superchargers in drag racing if the governing bodies would allow them. and im not talking about the import front drive classes. im talking about top fuel. who cares about straight line racing anyhow. thats all kinda boring

[engineer]

yes straight line racing is boring.... go with turbo because:
1) as said b4, toyota engines are very strong
2)in a way their characteristics are more user friendly as long as the turbo is not 2 big/wild
3)u dont need to change pulley size to change boost
4)it is a japanese car and u will find much more turbo products as the japanese spend 99% of their forced induction R&D, OEM and aftermarket, on turbos.

by the way, i might be wrong, but didnt the toyota altezza (same as is300) RS200 come turbo? which means u could just get an engine swap and also means there will be heaps of info about turbo'ing this engine and upgrading other parts of the car

[Reed]

i think a common swap for teh is300 is the 2jz-gte turbo supra motor

[engineer]

i think 1jz would be better... 2JZ has too much torque... it could be hard to drive etc. before u jump on me, dont forget that the top secret supra, the one they used for trying to break 200mph on british highways and so on, had an RB26DETT in it, swapped in for the same reasons.
