im pretty sure you can. the lsj guys are running theirs up to 9500-10k. i think theres a multiplier table for the rev limiter, maybe its only on the p12. never looked into it on the e37.

 

Well again that's not something anyone with a NA would be able to do easily. I don't think it's an option with the E37 either but I'll look later tonight. The Roush engine made power under 9k anyway. I'd think a smaller cam would be lower than that.

 

honda guys do it lol. we need better flowing heads and vtac

 

Don't gen IV engines have it now anyway?

 

Only on the intake.

 

So, UPDATE.

I'll be taking my spare cylinder head in later this week to have it milled. Guy says roughly $70 to shave it .030" so I think I'll bite. Then save for adjustable cam gears maybe? IDK yet. It'd be nice to have a spare car to drive while I take mine apart and measure PTV clearance but since I don't have that luxury it'll have to wait.

 

I just noticed my name was mentioned lol.

I know nothing about this so I don't need to comment.

 

For any of you in the distant future as crazy as me but with better luck, yes you can mill the head .030" no problems. You just have to not be a TOOL like me and triple check everything on install.

 

when you deck the head or block you retard cam timing
