FS: M20 Performance Camshafts from BimmerHeads

[ninjaotter]

Marked for later! I think this would work great in my rebuild.

Sounds good! Bump.

What would it cost for a m30b35 regrind, what specs would I be looking at?

I know this has been asked, but I'll ask again... Any dyno numbers for the m20 regrinds? Or any dyno number for similar spec cams?

Let me see if we have any B35 cores left. If we do it will be the same price! We usually do a 284 for the M30.

Sorry but I don't have any before/after dyno numbers to provide. I wish I did but none of my cars are even close to stock. Gains from a camshaft are also dependent on the exact engine and its supporting mods.

For the sake of conversation, let's say a well maintained stock internal m20b25 with the following:
Mark D 93 octane chip
17 lbs injectors
Ebay headers
Cat delete

I'm not looking for hard numbers, just rough guesses. Nothing I would hold anyone to. You can PM me response if you don't want others taking your reply out of context or trying to apply it as fact.

[MR 325]

Sorry but I just don't want to make any guesses.

Bump it up!

Understood. Does the cam timing stay true to the OEM specs?

Yes. You will not need an adjustable cam gear.

Any further questions please PM me!

Will the 274 require upgraded HD valve springs? Or can the stock tired springs handle the valve float?

Valve float? Stock valve springs are FINE.

I am running this cam in my 267whp M20 with original (good) valve springs.

YES, valve float.

I once installed a schrick 284 with OEM stock (brand new) springs and the springs couldn't close the valve fast enough ie. valve float. The valve was hitting the piston slightly. Fixed it with schrick springs but had to tear the whole thing apart which sucked. Anyway, will contact you guys in a couple months for a P&P head and cam.

Thanks, I am aware what valve float is.

A Schrick 284 cam is more aggressive than the cam I'm offering in this thread.

Please PM with any further questions. Thanks!

Going to have you guys supply me with S14 cams once the time comes!

Awesome, awesome, awesome.
