hey , my freind is about to buy an Rx7 s4 rotary , my supra is fast but im not sure if it would be able to beat his rx7 , what mods would i need to get to beat it , im gettin a new Intercoola and new exaust with a 3.5 inch dump , is there n e thing else id need to b able to beat it easy?

I have an idea, why not just take it to the drag strip and find out, honestly I don't see what motivates people to post things like this. As for your first mods, you should do alittle more research first, a 3" turbo back exhaust (including a new turbo elbow) and a few washers (roughly 1psi increase per 1mm washer) shimming out the WG will beat a TII easy, now if he has mods then your in trouble cause a 2500lb car doesn't take much to make it faster. That's just my 2 cents though.

i was thinkin of gettin a cat not a turbo back but hey ur the expert

thanx for all this , ur like the most helpfull guy on this forum ey cheers bro

Well it will be worth the extra money to buy the down pipe and turbo elbow if it's not the one peice kind, with only a cat-back the DP and elbow will be the restricting point, about 2.25", meaning you will gain very little HP from just a cat-back. Just remember not to get the HKS down pipe, it has a flex pipe that narrows down to 2.5" on the inside. I'd reccomend the "becauseican" DP if you can't make your own, it has a turbo elbow and DP in one, and the price is decent, here's his site..
