Oh, most likely you'll run into ignition issues, and you'll have to upgrade that too. Compare this to the Mkiv TT where all you need to achieve 500hp is a downpipe, a ten cent hose clamp, and a free fuel cut modification. Back to your mods though, note that a thicker head gasket in a 2jz-ge does not produce a combustion chamber with the equivalent shape and horsepower potential to a 2jz-gte. You also still may run into detonation issues at lower boost levels, since 1.3mm isn't a very thick head gasket at all. HKS made/makes a 2mm head gasket which may work better.

Here's an example of a complete na-T kit:

...and for $5250 you do get your 500hp, but on a car with substandard brakes and suspension. Based on your situation, I still say wait and get a TT. Doing all of these mods to turn an n/a into an na-T is something a student probably doesn't have time for. For what it's worth, I say take more courses and get your degree done sooner, or get two part time jobs and save up for a TT quicker. *shrug* Either way you go, I do wish you the best.

Phil! You mean I can get the modified RZ 6MT I told you about to 500HP just by doing those few things??????

Speechless...I my favourite car even more now!! Supra never ceases to amaze.
