nutter 1 Report post Posted June 19, 2009 Hey there i have my Headers beeing Made up at the Moment Just letting you all know but i have heard something thats has got my attention Apperently my M50 2.5L dohc cams can be replaced with the ones from a M3 1994?(please correct me if it wrong) I was wondering if this is possible,do you get Much of a power gain,is it a straight swap,do i need new values or what will i need? Or what cams(M3,Hot cams?,aftermarket) would be best to use to get a good boost in KW and torque for my motor if there is any? Thanks Nutter Quote Share this post Link to post Share on other sites
BM WORLD 1283 Report post Posted June 19, 2009 yes they can be fitted , if you do , get the ecu remaped to suit. also while you are at it fit a m52B28 2.8L crankshaft and rods and lighter m52 pistons Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted June 19, 2009 Just be careful - its USA M3 cams, not Euro M3 cams. I have also seen Schrick and "Sunbelt" associated with M50 cams. Its a lotta money for not a lot of gain? Quote Share this post Link to post Share on other sites
nutter 1 Report post Posted June 22, 2009 (edited) So in Cold air box and header and exhaust would be best bang for buck to improve acceleration in my bmw ? Im really just looking for a faster off the line speed as a top speed of 230kmh is fine by me at this point as i dont offten go that fast any more If any ones Knows a good way to spend 3g on making my bmw fast off the line please help i have v8 brakes all ready they look like they might fit with the 2.5 disc is this right or do i need the v8 discs? thanks nutter Edited June 22, 2009 by nutterbutter Quote Share this post Link to post Share on other sites
Forrest 35 Report post Posted June 22, 2009 ^ Power to weight is the key to acceleration, you can have all the hp in the world but you still got a lard ass car to haul. E34's are heavy. You wana get off the line faster take some weight out of the car. It is a 'free' mod too. Quote Share this post Link to post Share on other sites

c.robertson00 11 Report post Posted June 22, 2009 Why dont you just buy a 535i??? More tourqe and more power... Removeing weight from the car will make a difference too and it doesnt cost anything Quote Share this post Link to post Share on other sites

Thanks Nutter What I have been told you can do, and what i want to do to my M50 is this. By the way mine is vanos. You get your inlet cam reground ( might cost a few hundy ) and get the INLET cam from a non-vanos m50 and put it on the exhaust side of a vanos m50. I am still doing research on it, but from what I have read that is the best idea, and cheaper than finding US S50 cams.. Quote Share this post Link to post Share on other sites

If you want the quicker times change the diff. Quote Share this post Link to post Share on other sites
