I'm looking into getting an SC300 and I had a couple of questions...

I know that the SC300 and the N/A Supra both have the same engine, but what about the TT Supra? Did they use the same engine and put two turbos on, or did they use a slightly different engine?

Also, did Toyota use the Supra chassis as a base for the SC300? I just want to know if I can use suspension mods for a Supra on the SC300 (I think the weight is similar for the two cars).

Thanks...
