thanks

I'm right there with ya. That's something I have been wanting to do too. I wasn't sure that the M3 cams would fit, and also worried about how much labor would cost to have a shop swap them. I have 110K miles on my engine, and was owrried that more lift and duration might cause already worn valves to break?


Anyone know someone who did this swap? Are there any other incidental parts that need to be purchased as well? Should the timing chain be replaced at the same time?

just search around... there is a cam kit for a 325 that gives it 240hp

m3 cams should be fine alone... but i suggest new springs and retainers.. and if you already have the timing chain off ... change it.... cause it'll be a bitch to take it off later if it does go bad...

but i agree with Ciscokid find a cam kit...

Do an M50 intake manifold swap first.

There isn't really much to gain from better breathing cams if the main bottleneck is the restrictive M52 intake manifold. Also, get proper software, like the Eurospeed/AA software, or the Conforti cam software.

I wouldn't worry too much about the timing chain, maybe do the tensioner. Regarding the springs and retainers, they're not necessary, but are good to do, swap for M3 or better springs. M3 spring if you don't plan on going above 7000rpm.

I already have my cams, I'm getting them installed within a month. I've already done the manifold swap

there is nothing elce you would need to change. m52 head has the stronger retainers and springs, so you're fine. I would suggest M50 manifold and AA software from Eurospeed. Their site is www.eurospeedperformance.com
nice car thinair, have you been on the dyno yet?

what is better about the AA software compared to the Conforti
