325i Engine Rebuild - BMW Forum

Avlany · 07-21-2005, 04:38 PM

Well, its time. Me and few of my friends going to stack my car in the garage to remove and rebuild the engine. I just started this thread to ask some advice. If you did this kind of job before, is there anything I have to have or know before we begin? Anything vital? Any input very much apreciated.

Be careful with the cams. You can break them pretty easy. Other than that, just make sure not to cut any corners. Also, the grey form-a-gasket is wonderful for sealing metal to metal parts. Other than that, have fun!

I don't know if they have to be machined, but they should fit definetely.

Do you know any rough price estimate on those by chance ?

I would try going in the classified section of bimmerforums.com for some used ones, a lot of people part engines, make sure to get s50 tho.

Before you start doing this do A LOT of research man, theres a lot of really good mods that can be done once the motor is cracked open, s50 cams for one, uprated valve springs, etc. Also if you are interested look into the 2.9L stroker option, i beleive all that is needed is a s50 crank and rods. Also... look into knife edging the crank too, you can make a super fast revving motor doing this (its basically like the ultimate in lw flywheels, haha). Balancing and blue printing the crank to 10k rpms is also another good mod if you want to try to turn your motor into a high revver. Oh god the list of mods is endless, so many things can be done...

Good luck man!!

BTW - s50 cams can be had extremely cheap if you look around. I have seen a set go for as little as 160 bucks. The average set ussually sells for 250-300 though.
