I want to upgrade my cam shaft on my E30. What products are good for reliability, performance and price? Who should I deal through?

They will custom make you a cam milled from a Shrick blank billet to your specs. Any specs you want.

$325 USD

I have one in my m20, and I'm very happy with it.

does that affect the idle? also what gain did that give you? i have just begun to get parts for the engine, i opted for a stroker kit and was going to go with that spec cam. 270 something i think it was 274, was going to go with the 288 but i dont think that would be good for the street unless i rag the crap out of the motor, rev limit, ha ha, that was funny but stupid my bad.

My idle is just fine with the cam. I also have a 12lb flywheel, so that further hurts the idle.

288 is too much for a 2.5l bottom end IMO, 272 or 274 are just right. 288 is more 2.8L bottom end territory.

Outch 325USD...I paid $150.00 cnd for a regrind 290/290 11.5mm lift and that was including shipping....

Got it done in Montreal for those interested...
I actually got 2 done ....the other one is a 272/272 11.5mm lift... very mild...

Idle is not bad at all with the 290 cam

I will try to get the info ....

i am going 3.0L or 2.8-9L i havent figured out yet. the guy i get my parts from has built many bmws. his shop is accually terry sather auto, and is a bmw shop. i still want the m20 because that is the time the car was built, you know? i want the car built to the time as opposed to a newer bmw motor. thank you though for the input, but what king of gain did you get from the cam, seat of the pants feel.

First you need to get a good working engine like a 2.7 and up with high compression for a cam like a 290....

I have not dyno the car and have done too many mods for me to tell what kind of hp the cam gets out of the engine....

I am sure there are numbers out there for such a setup...

Regrinds and new cams aren't exactly in the same ball park.

You mind telling me how you had a stock cam reground, and instead of loosing lift (which is part of the downsides to reground cams) you gained 2mm of lift?

regrinds cut off the cam, i never use those. we always use new ones in our vehicles. remember reGROUND.

That's it...grind on the other side which gives you more lift...
+ they add more if needed then they polish it ....

I don't see how grinding on the other side of the lobe would produce more lift... but whatever you think.

Welding more metal onto a forged hardened steel camshaft is a brilliant plan. Except its really ghetto.

Buy a new cam....

Yea yea.....I say try it and then you can tell the pros and con....

Don't just Skunk it from your unknown experience with the damm thing....

When comes time to put your money down for a cam you will think twice about it...

i have no problems buying a new cam. i run a mechanic shop and will never put my name on a reground cam. to put it in perspective i got toyota to custom build a cam for my land cruiser (85 egine no longer in production, its also the most powerful one i have seen.) and it took forever and then still the only way they would ship it was by boat and it cost a fortune for the cam and shipping. but because i could have gotten a reground one but wanted a new one i chose that way, also i got a billet cam that i never have to worry with or run different rockers, valves or what not. i have years of expirience building engines, when did i say i had no expirience. but if i spend the time to build an engine i will garrantee it will have new parts and not anything rebuild, reground, welded, it doesnt matter. 300 bucks is cheap anyway, but i never pay full price because i get a shop discount and ussually get jobber prices anyway. i am not saying that they wont work, i am just saying i would never run one.

I'm very familair with how the regrind process is done. The machine shop that did my head showed me how they regrind cams (in an attempt to sell me on the idea) but after seeing the process I went with new.

Regrinds are ghetto.
