About 12 grand. The compression has been raised to 12.5:1. Forged pistons and rods bored .020 over. I'm running a custom grind cam from crane. 273 degrees of duraction, .400 lift on exhaust .395 lift on the intake. Custom intake manifold and exhaust manifold. The head has been race ported. It has all of the usual bolt ons, UR udp, and cam gear (yeah it's a sohc

) along with a custom cold air intake. For engine management I'm running a custom AF/X race ecu and using the Perfect Power SMT-6 to do the fuel tuning. Redline is 8100. It has a nasty lope at idle and doesn't like running under 3k. Above that it's literally a monster. The car is also gutted with no ac or ps. It weighs 2337 lbs without me in it. I'm also shooting a 50 shot of nitrous through it for some "just in case"

So right around 12k in the engine, drivetrain, and electronics... Worth it? Probably not. But I "currently" have the worlds most powerful single cam second gen neon. Plus it's driven over 70 miles a day.
