I think CR would be around 12.1-12.3:1 (11.5:1 is for the usdm model, non flat top pistons, 9.5 CR stock).

Nice setup. 189bhp here before mapping and running überlean -hope to be around 210-215 once steve@fctuning does some magic with Nistune-.



Would you mind sharing more info about setup?

No thread for the moment, I will create one once my car is tuned, including some videos.

Ported and skimmed head, polished exhaust ports, grinded valves, Supertech manganese valve guides.
Catcams 518.
Catcams camshaft springs and Brian Crower titanium retainers.
SR16VE pistons and rings.
SSAC 2.5" header (thinking about modding its secondaries or going to a tri-y, Powerland... who knows), decat and 2.5" catback.
AEM CAI (thinking about going a Hotshot 3").
Unorthodox pulley set.
Thermoblock spacers.
Exedy Stage 2 R-Type clutch + Fidanza flywheel.
Grounding kit + NGK 7 heat range plugs.
Nistuned by steve@fctuning with 8000rpm rev cut (pending).

I am running like 17-18 AF below 4000 rpm and around 14 over there, my ECU is crazy right now. In a trustworthy dyno, 189 bhp at 6800rpm and 210 NM (120 ft*lb?) at 6400 rpm :S

I need to do something with my brakes too (working on adapting an electric pump from a Pajero), since cams leave no free vacuum to the servo.

Running 310mm rotors at the front, will 4-pot Wilwood Dynalite, Z32 17/16" BMC and Goodridge brake lines. 279mm p11-144 brakes at the rear.

Crane Cams vacuum reservoir helped a bit, but I decided anyway to put a switch (next to the warning one) for the ABS on/off.

Regards.
