Just the usual bolt-on's: Mugen Intake, Skunk2 IM, Z-Speed Camgears, DC Sports JDM 4-1 Header (2.5 Inch Version), Spoon Street Muffler to shut it up, Tuned via Apexi Power FC ECU

Everything else is OEM Honda.

What pistons are you running and with what compression ratio?

I'm planning a rebuild on my b18 now, nothing extreme just bore/hone and head reco. I'm thinking if using p73 usdm pistons which will bump the compression up slightly but keen to see what you used since your results seem pretty good with a near stock build.

OEM 81mm PR3 B16A pistons, with P72 head= 11.3:1 static compression.
