Since the block is the same as the Supra, with the right mods installed properly, the IS300 can be turned into a real boosted terror. It will cost you though....
The block in the IS300, as with the old SC300 and old GS300, is the 2JZGE. It is the same block, but not the same engine. Meaning, the IS motor wasn't built from the factory to handle boost, there are a lot of turbo components on the 2JZGTE that are absent from the 2JZGE. That being said, turbo components from the Supra will not bolt directly on the IS300. The ECU has to be controlled/tuned/even bypassed in an IS300 to make it into a turbo car. Here are a few of the manufacturers of quality IS300 turbo kits listed in order that I would purchase from:
1.) Toyomoto, Inc. - Miami, FL - http://www.toyomoto.com/
I rode in a 550 whp turbo IS300 from Toyomoto, and that thing was scary fast!
2.) Peter Farrell Supercars - Maryland - http://www.pfsupercars.com/
3.) Powerhouse Racing - Texas ?? - http://www.powerhouseracing.com/files/index.php
4.) Swift Racing Technologies - Maryland - http://www.swiftracing.com/ |
Good post jdub24! I'd add that the n/a (normally aspirated) head is completely different, which is why the 2jz-ge engine doesn't handle boost as well. On the bottom end, the only things that are different are the oil squirters and the compression of the pistons.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
