AP1 S2000 SC HEAD BUILD? OR BONE STOCK?
How many of you ap1 owners have built your head, being supercharged or upgraded the oil banjo bolts to ap2? Or just running on a complete bone stock f20c? Please list your setups thanks!

Stock ap1 long block 315ish whp comptech s/C with over 50k miles untuned. Motor runs perfect. Doesn't burn oil (Motul 8100). And I've driven a 5 hr round trip and ran this car at the track twice so far. No issues yet.

Ran 8, 12.5, 14.5, 16.5psi on a completely stock '01 motor while revving it to 9k. Exhaust valve guides were shot at ~105k. Installed new guides, supertech inconel valves, supertech valve springs with titanium retainers and ARP head studs; making a hair under 24psi @ 9300 RPM now.

Cant beat OEM for reliability. I did a full head build, ferrea comp plus valves, BC dual springs and afew other tricks.... Just recently rebuilt my head and went back to ALL oem parts,the ferrea valves went out of round and caused the head to lose compression. We also noted premature wear on the valve guides, never had those problems with oem internals.

100 percent stock head and block. So far i am running 461whp at 16psi. No problems. Car is capable of doing 27psi but im having fun at 16. I run 19psi occasionally. As well. As long as the ap1 retainers are not over revved they are fine.
I bought supertech springs and retainers but opted not to install them because after reading more and more i found that oem is the way to go.
