I have searched for a while, and I have found some people saying to replace the ignitor coil. I want to do this, but can not find one compatible for my auto. Does anyone know anything that would work for higher performance. Also are there any other high performance tips. I have headers, catback, muffler, intake, and the underdrive pully. Any other advice would be great, thank you .

Have you tried port and polish on the heads, it's expensive but definitely worth it.

do an intake, a borla header with a cat delete pipe and a catless mid pipe with a high flow muffler. then add a msd ignition to it, port and polish the heads, and get a light weight flywheel. anything is possible, it just depends on how much money you are willing to spend....... if you do the exhaust, i suggest that you keep the stock parts for emissions.....
