Common mods for M50-swapped cars?

[CleanAzzE30z]

Im not planning on it right now since Im having so much fun with it at the moment (325e), but Im thinking Ill want to still mod this engine at some point. Just wanted to know a few common mods, since I feel like Ive started fresh with a brand new engine to play with and start from zero. I already have a set of ///M3 cams that are going into the car soon. Thanks in advance.

21.5# injectors, 3.5 MAF, eBay headers, bimmerworld sells the samco 3" to 3.5" intake boot adapter, look at TRM for chips...

[CleanAzzE30z]

Oh I have the headers, injectors, and a custom chip. I just thought that was required so I didnt list it as a mod. Nice to know though.

m50 mods = lots of boost! :mrgreen:

it'd be one bad ass 4 door.

3.5 (540) MAF. make sure the chip is for all of these. pulleys add a little. if you dont have one already id recco the stewart performance water pump. not really a hp mod, but its always better to run cool.

farbin pretty much covered it all.

I've got an underdrive PS pulley from Unorthodox Racing I'll sell you for $50 shipped :)

Do not run a crank pulley though, the others are fine, but some engineers like to think harmonic balance is handy.

I didn't get the specialness of that pump, I'd rather just go buy a metal impeller a/m one.

remember you have to smog it

didnt own on personally. ive seen the diff though between my old m52 swap and E30Groupies s50. there is a difference in running temps. if you look at the actual design of it, theres a huge difference.

Turbo is the only way to go on an m50. ;)

s50 is a popular mod for m50 guys...hehe

just grab you some m3 cams to go with the MAF + inj +software upgrades.

true, the money you spend making more power out of a m50, you could of just bought a s50...
