EBay would work I guess, but if you're going to do it, then please do it correctly. Check out some websites such as SP Engineering, Horse Power Freaks, Titan Motorsports, and WOTM.com...all are great companies that will really help you get the most power out of your Supra. Good luck!!

The EBay company is probably XS Power or something similar. A buddy of mine has thier turbo kit on his Civic and has had to replace the manifold due to cracking issues, even after re-welding, and now the turbo is smoking. Not sure how many miles he has had it on for, but it shouldn't be smoking this soon.

Good luck!!
