My D23 is all stock internals, 67mm TB, 2.5" MAF, F2 Header (wrapped), focussport stealth exhaust minus the front resonator, the exh ports on the head were matched to the header, EGR deleted and custom tune by me using SCT pro racer.
I'm running 4.06 gears and a quaife.
I actually think I got a small jump in HP by installing an oil cooler!.
When I got my oil temp gauge installed earlier this year, I learned that my engine was running about 290F on the oil temp after about 10 laps flat out.
I installed an oil to water "mocal" style cooler and now it runs @ 220F. Since the engine squirts oil on the pistons to keep them cool, lower oil temps means lower piston crown temps, which keeps the clearances looser and keeps the engine from pinging etc.
The car was just an animal out there........
and as an FYI I'm running castrol full synthetic, 5W20, which puts my oil pressure at a solid 60 PSI on track.
