    Hi,

    Been looking around and I know that US spec M3 cams are a good upgrade for the M50B25 engine. But would they work well with a turbo'd engine or would they be too aggressive?

    Plenty of people in the US turbo their M3's so I don't see it being a problem, you should get the car chipped any how after you have fitted those cams to get the full potential so the same applies if turbo'd, unless doing it on the cheap.

    Ah yeaa, good point. And I was just gona put the cams on and leave it untill the engine comes out for a full rebuild when a nice GS-racing snail gets strapped and I would be running stand alone. Would get some1 who knows what they are doing to map it unlike me. Never done it before and dont wana bugger it up

    The US cams will only further enhance the setup, But the M50B25 can already flow enough to break the pistons and rods. So not really a gain per say unless you plan on going further then 500hp which is in general considered the upper limit of the M50

    I dont think i would want more then 500 bhp to be honest. I already got the cams and nearly installed just hit a couple of snags with the inlet gear bolts deciding to strip when tightening to stage 2 of 22 Nm but a trip to the scrappy tomorrow should do the trick as everything is timed up just need the inlet gear securing

    Well since you have them install them,

    Then when you go turbo you´ll just need to run less boost to achieve whatever powerlevel you want. Which will make said powerlevel more safe on your engine due to the lower intake temps.

    ah, i didnt know cams do that i heard about the 3.1 stroker kit that consists of a 330 ci crank, etc on this forum and was thinkin of doin that because i wud get more power from displacement and wud not have to screw the tits off my engine. i want a canny bit of power but safe power definately want more then 310 bhp as I drove my mate's 350z GT and I am determined to make my car faster then his for less then he payed for the Z

    How do you plan to get more then 310hp ?

    It´s not going to be easy using a M50 as a base no matter what size you make it.

    I´d actually reccomend you a turbo. When you have been in a bmw turbo car you´d understand
