S50 cams in M50
Hey guys quick question, can you run S50 cams in an M50 without a tune? I know you'll have almost no power difference without it but is there any negative side affects other then that?
Thanks
P.S I do plan on getting a chip but 350$ for a custom one from TMS is a bit pricey right now

Look up E.A.T chips from Mark D. Ive got his chip on an stock M50 and very happy with it. I know he does have a chip for the s50 cam set up as well. His price should be better then $350

Who told you there won't be a power difference? It's still going to be a huge difference.
You don't "need" a tune.

Yes, you can run the cams without a tune. There will be a power increase, but a proper tune will give more power. I just installed s50 cams into my e36 last weekend. I used a Mark D chip. Very nice power increase.

im a complete noob so please take in mind.
-- does installing higher quality cams ( S50, S52 cams ) give you the ' rumble ' idling sound?

I've never noticed his car do it and I've been in it/driven it many times. Compared to a small block chev it doesn't make that noise but what are we comparing it to?

From a blown S50 motor, or someone who has upgraded cams in their S50.
Post a looking for thread on BMW sites and cruise the for sale sections, most have a search function.
Performance cams can be ordered new from companies like sunbelt as well

I'm running a high duration Schrick intake cam meant for an S50 with tube Supersprint headers and straight through cat-less exhaust... I get a blugblugblug sound and a shaky car at idle xD
lol actually sounds like shit, but I'm pretty sure my exhaust is leaking somewhere too.. :/
