Anyone have any shops in mind to do the port matching? I have one shop who is giving me estimates to port match the intake, head, and exhaust together. I was curious if anyone has done this. Urge seems to have a bunch of expertise in this area. Too bad their head work would put us in SSM

The more I've read this thread, the less I'm inclined to build my Z3 for BSP. It is amazing what you guys can fit or do to make the cars legitimate BSP contenders. I'd be lucky to fit 17x10's with flairs. I'll always subscribe to this and other S2000 threads as I find the amount of info and input off the charts but am probably resigned to STR but am very impressed. Keep it up and I'll always have something to shoot for.

Were going to skip the head/intake work for now. Don't think its worth spending $500-$1000 on that stuff. Our car made plenty of power in str trim and we are just going to retune since we haven't after the decat. I'm going to customize the Berk 3" exhaust slightly for weight and sound purposes and then retune. Look back in this thread at my str dyno chart. The car has plenty power. By the time were done probably pick up another 10-15hp and 5-10 tq throughout with the stock setup

port matching will not gain you anything on this motor, at least that is the case for the intake. any enlarging within bsp trim will lower your air velocity during a critical period when fuel is being atomized. For the exhaust side, it is possible to gain something. But from what urge and church have told me, gains would be smaller then what can be seen on dyno is non existent.
but hey you never know! maybe ill try something next year.... so far i polished the last inch of my exhaust ports. intake ports left rough for atomization.

Sorry to hear. I have some leads on a theft recovered S2000 if you are interested on a cheap start!
