A Question About The Engines

nccrashnburn · April 19, 2006

I have my 02 is300 and i am wondering if it is possible to get around 450 hp out of the 2jz-ge motor. Would it be better to a supra tt motor swap or could i just build the stock motor. If so, would the axles and/or tranny be ok with the power jump? And last but not least, if i do build the motor what mods would be best to reach my goal of around 450 horses (i have been told to port/ polish the head, get better cams, valve srpings and retainers, injectors, spark plugs, msd ignition, coil pack, controller, redo the whole induction system (intake, throttle body, exhaust) get a turbo kit w/ boost controller. I already have a nitrous kit with a intercooler sprayer.

Any help would be great

Thanks

Also what is the best as far as suspension upgrades go ( i got tein lower springs, told to get coilover package though, sway bars, strut bar, and tower bar.)

You'll have to go turbo to get to 450 whp for sure.

I know this but what i was wondering is if the stock motor can handle this power or if i should go ahead and get a motor swap to the supra tt

Dont know them. But they seems price worthy.
