The 2jz-g(t)e are great engines, but the ge, in the IS, is tricky to mod. Currently several companies are competing to produce a viable FI kit for the IS and almost all have failed to date. The issue is the blasted multi-link ODBII ECU that is proving to be a major pain in the ass. the work-around has been a stand-alone computer, and I don't think there's any way around this. FOr example, I have a piggy-back ECU that works w/ the MAF sensor in my HFI to alter the stock ECU's air/fuel ratio (more power) but the stock ECU, somehow, "figures out" what is going on and sllllooooowwwwwly starts to slide the A/F mix back to stock. So you have to unplug the Neg. terminal on the battery and reset the SOB every 2-3 months.Originally posted by scurry
I think you answered you own question. Especially if your looking for performance and not luxury. The IS300 is a sweet car and it does have the 2JZ-GE motor which can be modded like crazy. The draw back to this is the cost for those mods, and the question if the drive train can handle the mods. If you have the money and are willing to spend it I say go for it. However you can have less then $30K total investment in the WRX and be making 320hp. How much will it cost to bring the IS300 to this level? Not to mention the extra $6K for just the car.
