It's a dog down low and while great fun, is not a streetable car (triple plate etc) Buy parts that will work for what you what if it to show off but the shiney bits. Phil


Where there's a Phil There's a way

No I have a mk3 supra the standard engine for the mk3 is the 7m series. I have a 7mgte.

Sorry it took me so long to reply I wasn't notified that someone posted.

That's funney iv heard the opposite everywhere iv been. On a turbo cxar biger is better to allow the exhaus to escape faster and to alow scavenging to occure in the piping. The more free your downpipe and exhaust is the faster your spool is because there is leas back preasure. The faster you can spool up the quicker you get your power. I have also been told that you can see gains of 1-3 psi and 30+ horsepower just from a 3" high flow exhaust.

Someone correct me if I'm wrong please
