What cams would you go with?

[cossack]

What cams do you guys recommend i go with. Seems to be a couple options.

I plan on installing the cams and the airbox hopefully at the same time. Followed by vac throttle bodies, and vac pulley kit. Also planned is the 3.91 gearing as well.

Someone please confirm info below to that of what you know. Below are the cam degree setup that I'm having a hard time narrowing down to.

1. 280/272 - Stock US?
2. 280/288 - CSL?
3. 304/296 - Schrick Option

Are any of you running non csl cams, if so why. How has it affected your performance, and why did you get different cams.

I know the 304 296 make no difference to pace with the higher lift, but some like to get them because they have the thickness to custom grind the cam for high power builds:thumbs:

No point going for Schrick CSL spec cams.

I will be going for higher power once my engine shits itself. Might be tomorrow, might be 3 yrs. Who knows. But it WILL be staying NA. I dont think SC would have longevity for track work.

[shane@mbtech]

Just seen its a normal M3, so CSL spec cams would be a worthwhile upgrade.

[83SY]

Correct if I'm wrong but throwing all this money on CSL bits and pieces, would it be cheaper to buy a CSL???

OP's in US and BMW saved them for the countries with twisties :D

:hahaha: I thought anything under 6 litre in the states and your a pussy!!!

[shane@mbtech]

not allowed in the US, not emissions approved.

and probably also considered a cheap run around:banghead:

So if you were a yank you couldn't even import one? Or would you pay massive import duty ?

Sy is that politically correct whet you just called him :whistle:

[bryce]

I heard a rumour once that a rich dealer imported one for his daughter.

[Mark CSL]

Juan Pablo montoya has 1 but cant drive it on the public roads legaly

The CSL is not allowed in the U.S. without massive Federalization requirements which would make it cost prohibitive.

[LeinsCSL]

Wasn't there a similar thing with the 959? Didn't the Microsoft boys get around it somehow, although possible with a load of cash?

If so, OP go send Billy Gates a few pics of a CSL!

[cossack]

I'm going with the CSL cams and ratio of 288/280 degrees which most of you guys luckily have as standard. Figure hell with it, go even further oem csl with my car.

Yes, as some of you stated we cannot get the CSL in the U.S. However two people have somehow imported them, but from my understanding they are not street legal. For me it just made sense to take a CS (ZCP) M3 which had some csl components already and finish the transformation. I've spent over $30,000 USD total so far in all modifications. I'm not done with the project, but what i ultimately want is a full transformation down to the damn cardboard trunk liner.

Luckily I may have an individual who I'm dealing with about the oem csl airbox right now, awaiting on pictures.

Not possible for the next 16 years easily, in 2028 it will be available to bring in as a classic. Until then we are SOL :banghead: even if you do bring one in somehow, the smog/emissions without paying someone off you will fail the visual check even if you pass with the csl cats. Too much risk, and too much money to try to bring a real csl into the states to only have to dumb it down for crash testing requirements as well. I believe there was also a rule about having to crash test the parts or the car to allow bmw to bring the car to the U.S. market. I believe that is why BMW avoided the U.S. market with the CSL.

For me doing the transformation has allowed me to retain the valid registered vin of the m3, even though i've added most of the csl parts. Just in case you say why not bring the csl and swap vins well this may be a good reason not to. If i get into an auto accident, the vin is valid and registered as an M3 and not a csl or a csl that swapped vins with a wrecked M3 which would land you in jail if you get caught. The possiblily of being in an accident to have someone find out you swapped vins is worth fleeing the country, so the risk is not worth it.

Just out of interest....where did you get your info on what the standard cams are....as the 288/280 ones are not standard...they are an upgrade from schrick...

280/272 standard

288/280 will need schrick springs/retainers etc

But a worthwhile upgrade.

[shimmy]

280/272 standard

.

I thought that was stock M3 cams not CSL.Nth out CSL was 280/280

[cossack]

Link below is the only place that stated the degree of the cams. In the link you'll find the stated 288/280 degree setup as standard. I hope none of you replaced the stock csl cams for schrick one of 288/280 then if that's the case.

http://www.evolve.ae/forum/index.php?/topic/4044-bmw-owners-modding-your-e46-m3/

For whatever reason i don't know anyone who knows for sure what degree the csl cams are. So far not turner motorsport, nor any of the enthusiasts I've talked to so far. The verdict is still out on this one.

[cantfind1]

That's what I understood it to be.......however you can use your standard springs and retainers you just need to replace the rocker arms... as long as the 280/288 ones are standard lift.

[cossack]

Below is the link of the lift duration on the schrick camshafts i believe. It's the same on the csl as the std m3 at 11.6

The difference in the standard vs csl m3 is the 12 exhaust valves, which are the same length however are made out of lighter metal on the csl. As well as the camshafts which have a higher intake and exhaust degree spread. Part number can be found on realoem.com. I believe the csl cams are the 280/288 setup, from doing more reading and digging of all forums and posts. I believe the stock cams are 260/260 on U.S. and standard Euro M3's. Again I'm not even certain. Even when i get the csl cams to my house i don't know how i'll be able to measure the degrees on the cams. At this point all i know is its more aggresive, and will be better for me then what the car came with.

First Number is: intake / exhaust.

Shrick sell 280/288 as an upgrade to csl implying that the oem csl cams are lower in duration, they also sell 272/280 as an upgrade to stock m3.

I believe CSL comes standard with 272/280 standard M3 264/272

This is my understanding too.


What's your engine spec?

Wouldn't you like to know! lol:beer:

and which engine?

Just curious, have you just had cams fitted or a built motor?

Dont bait me or ill mention your shite tyre choice again:partyman:

[cossack]

I figured for 475 pounds OEM csl camshafts were at a decent price that I'm paying.

In any case I know it'll be better then what I have now with the stock U.S. Cams. :-D

[0-60Motorsports]

I will be going for 288/280 or oem csl cams, whichever ones come up first :)
