Hey All. My son races in a 4 cyl Pure Stock division with a 1994 Integra. It has a full cage, racing fuel cell, but a fully stock drive train. We had some good success last year (four thirds and 2 seconds), but I need to learn some performance tips to get a few more tenths out of this stock motor. It's a B18B1 out of a 96.

More pictures and info facebook.com/67BLR/ . Hit me up with questions on the car. I'll be searching around for perf tips.

Looks like fun -- we race a 92 Integra in Champcar with a stock B20.

I'm sure your rules are very restrictive but here are a few ideas, probably all illegal for your series

  • port match intake
  • extrude hone intake
  • run a larger throttle body and port match it
  • port match exhaust
  • head work, open the bowls, polish
  • regrind cams
  • run thinner oil
  • chip and tune the ECU
  • ARP rod bolts and run a higher redline
  • deck the head
  • high compression pistons
None of these will do much on a stock drivetrain though

All good suggestions - but all but thinner oil, I think, wouldn't be legal. What about removing the airbox resonator, bigger injectors, plug recommendations, etc.?
