I really, really appreciate the info, TalonBoy, thanks a lot!
I tried
http://www.GarageSPL.com and it turns out that this is their website, it has all those cars you mentioned earlier.
I got their address from there too, and will definitly stop by today.
I hope they can also tell me what's wrong with the whole blow-off valve thing on my 89 Supra Turbo.
Thanks!!!
