I've been looking for something like this for a while. I can dig it, good work thus far. Thanks VQman.

thanks but it's mostly a cut/paste job from the old forum..

S3, S4, S5 cam comparison - SR20 Forum

Dang, I never tried looking there for this. DOH!

Stickified

Looks like BC cams are more closely related to JWT C grind cams.

Wouldn't have thought that...

yeah, almost copies.. I think i'll be doing BC stage 3's if I can ever get around to it..

Stock GTI-R DET cams (IN- .394 LIFT / 248 DEG.DUR - EXH - .394 LIFT / 248 DEG.DUR)

^So who is running a GTi-R exhaust cam in their highport/lowport? I have a set, but never tried this combo.

That's what I ran in the DET. Could have sworn they were closer to S4's though, didn't really pay any attention.

yeah I was noticing that the GTiR exhaust cam would go nicely with a highport intake cam in the better flowing lowport head.. (if you didn't want to shell out big cash for a set of aftermarket cams.
