E30 with M30B35

[slammin.e28]

That's a B35 AFM with the OEM cover still on it.

Well it doesn't look like the AFM that I have and you can only see a little bit of it. I thought he had a mass airflow sensor. I'm trying to find out if there is another airbox I can use besides the huge regular one.(It doesn't fit very well with AC)

^ @Graveshaker, what airbox is that?

lol :p

[kronus]

You were able to keep the stock rubber intake boot? Low PSI non-intercooled, I'm guessing?

[slammin.e28]

That's the AFM.

Mine was pretty fast and loads of fun......

Any cam recommendations? My M30 is from an E34, so it has the big intake valves. I don't think I want anything too radical, but I figure that I should do a cam swap/head refresh before I shove the thing in the car this winter.

Go with a 288, i've built a few M30 engines with that cam and they all went awesome! it's lumpy but you'll love it :D

I suggest talking with Paul Burke...

If you want the most performance gain out of your new cam on an M30 then a regrind is not an option. It compromises the already lackluster valvetrain geometry.

A lot of older heads have bad cam journals and worn rockers...

There are plenty of decent cams I think but finding the "best" for your specific engine will require some discussion with M30 engine builders. I suggest talking with Paul Burke or others on mye28.com.

Schrick.

deltacam has a nice 284 regrind

3.25 is already in the car so I'll start there but thanks for the input. BTW my vert will be on the lighter side with attention to all areas of unsprung and reciprocating weight as well.

[LJ851]

Yeah I'll let you know how I like the B35 to. I'm currently waiting for my forged 10.25 CR pistons from Paul Burke to arrive to go with some other NA goodies I'v already aquiured for my 89 vert build. Got 3.25 and 3.46 diffs on hand to see which I like better. I think the 3.46 will probably spin my 225/50/15 Zeix 912's a little too easy though. We'll see:)

I had a pretty stout M30 E30 with a 3.25 LSD and i was wanting a 3.46 the whole time. Yes first gear is useless, but it just it seemed to want just a little more gear most of the time. I say start with the 3.46.
