If you're happy with the performance, then there is no reason to go into the engine for upgrades. Save up for a D1SC from Procharger, then invest in an EBL-P4 to control boost. Would be an extremely neat and clean install, and, depending on how much boost you run, will just about double your power output. Nice looking car by he way...
i have thought about a little about boosting just not sure about reliabilaty all i do with the car is normal fluid changes and tune up and put gas in i have no problems doing any work on the car i know my way around inside motors quite well and i would run as much boost as possible
Nice thing about the EBL-P4 is it is essentially a Flash oriented system, installs in the factory location, and you can tune on the fly. I went with one and will never turn back to burning proms, and boost is a breeze; 2 Bar, 3 Bar, you name it. Controls everything your stock ECM does, but no more chips, and with many more features...
