Need help on 2.7i build

[SirWolfian]

Well I've been looking for some information on a build, since my 2.5 engine is having problems getting oil on 2 cylinders and making it smoke a lot at high revs (+4k).

I already have been told by a friend to make a 2.7i build. Using Seta pistons, 2.7 crank, idk which rods, 2.7 block, 885 head(i head), i intake manifold and other parts.

Well guys if you can help me I would be eternally grateful.

That is one recipe. Several ways to get there.

http://www.e30zone.net/e30zonewiki/i...Building_a_2.7 is a good read

My build is a 325e lower with the EU 323i head. The rest is all 325i parts.

Bought an m50 and because my bad luck it was pretty worn out and the cams were damaged so I sold it for scraps, hell i spent bout 250$ on that engine alone, which came form a 525i 92' regretted buying that engine.

I'm trying to stick for an m20 stroker at the moment. If in any moment I struck gold with a decen shaped m50 or s50 obd 1 I'd be the happiest man alive

Glad you posted this link I was always under the impression that my early eta motor mated with a 885 head would produce 8.8:1 The link says it would really be 10:1

I've never heard 10:1. I've heard 8:8:1 in basically every thread

euro motors are higher compession unless you have a euro spec motor you wont get 10:1

Guys, another question, if I run a 2.7i system with full short block e (pistons, crank and rods, and I head with I intake manifold throttle body, what set-up should I run with, turbo or N/A?
