m30 matchups thread

[euroshark]

The M30 is around 15lbs heavier than an S50 iirc, the M30 is 315lbs.

cool thanks for answering my question

how is oilpan clearance compared to the m20? also whats the fuel consumption lookin like? compared to the m/s50

[Funkmasta]

I got 21-23mpg beating the holy living hell out of it on the trip to Bimmerfest.... I wouldnt be surprised to hit 30 behaving.

[euroshark]

Yeah, I bet 30mpg is very possible in an E30. My 3200lb 533i gets 27+mpg on the highway with higher flowing injectors and bumped up fuel pressure.

[Funkmasta]

which diff do you have? 325?

[euroshark]

I think all 533is came with a 3.45... I've never checked mine, but I'm doing around 3150rpm @ 80mph in 5th for what it's worth. 225/50/16 Yokohama AVS ES100s.

yeah, i have 3.25 running 215/40's and i'm doing 67mph in 5th gear at 2500rpm. You're running a tiiiiny bit shorter than me.

[Funkmasta]

M3fan, how did you get your tach to work? which motor wiring harness are you using?

[sticksdaman]

any measurements as far as oilpans are concerned? like distance to the ground at stock height?

[euroshark]

I didn't think the oil pan looked much lower than stock honestly, I thought it had adequate clearance. I'd still go with one of the 666 skid plates or something though if you plan on running really low.

It pulls HARD, omg and wow went through my mind a few times :). Its a new world from the M20, especially from the eta.

I'd imagine they didnt put the m30 in the e30 because no one would buy an m3.

Probably so but if I am not mistaken I think Alpina did offer a e30 with the m30 in it

I'm using the Engine harness from the car I bought. the '88 325 supereta engine harness. it's already motronic 1.1, so it's completely compatible with the Motronic 1.3 from the E32 engine.

Just extend some of the wires in order to reach the sensors on the M30 engine that are in different locations.

[Funkmasta]

hmmm, I used the M30b35 harness with an adapter. Even though the correct pins are in the c101s, mine still doesnt work. sigh.
