I have been watching that motor for a long time too :)

I got an English to Swedish dictionary just so I could read some of the threads! Thats dedication!!!

A megasquirt V2 unit popped up in my local e30 group last night for $250 with the trigger wheel and harness. I haven't gotten around to doing my research on engine management but I didn't want to miss out on a good deal. I got a rough idea of what they go for and decided that was probably decent.

Anyway, looks like I'll be going standalone. I've got a lot of research to do.

Yeah I want a late model two door and Im trading a guy that has a 91 318is. motor will need work but pretty much everything else on the car is new. So looks like turbo m42 for me.

Plus there arent many m42 turbos and I like being different. Kinda like I'm the only one not running a front bumper lol

[MF DOOM]

Buy my head and injectors! Ill make you a deal Pretty stoked to hear you're going m42.

[Peattie]

I need to fix the bottom end first. lol .

[ccsdo5]

Hey guys! So I have a 1988 325ix now that I'm fixing/ daily driving. But I'm looking for a 318is that needs work because I wanna build it from the ground up and turbocharge it. Even though I don't have one yet, what do you guys think would it be possible to push 250-300 whp with a M42 if I fully rebuild it and what not.

Just kinda looking into this and wanting to get information from others that have done it.

[wazzu70]

Shouldn't be an issue. Get ARP head studs and an MLS if you want to drop compression.

What is everyone doing about the crank case vent? Catch can? Breather filter?

[e30guydownunder]

I'm going to run 2 -10 lines off the rocker cover into a 2l catch can with a breather.

[MF DOOM]

to tha flo.

I have a catch can that i may install someday..

[Leon T. Trout]

I read somewhere that having negative pressure on the valve cover/ crankcase was a good thing which makes me thing that having a sealed catch can connected to the valve cover and before the turbo would be a good thing.
