hello everyone,
Today i purchased a 1998 white GSR with a 18G greddy turbo kit and intercooler. the car only has 16k miles and i look forward to all the knowlege i will gain from this forum!

Question: The car now has a Mugen Twin Loop exhaust that i believe is 2.36 or 2.5 inch piping. will a 3 inch exhaust be more suitable for my set-up and yield more power? The Blitz power meter measured around 245 whp at 8.2 psi - i am planning on running Hondata s200b and getting it dyno tuned soon.

thanks

 

3in ex will make more power.....

 

what kind of ignition would be good for me?

 

The 3inch will yeild more power. If you are going with a stand alone setup I would go either MSD Digi 6 or maybe the 7(haven't read much on the digital 7 yet). Good luck with the build up.
