big power m30

[sideways7]

i had to change a lot of angles to make everything fit more easily. so, not much forward progress... but, i'm happier with it now. i also added the wastegate.

Looks awesome.

[sideways7]

thank you. i appreciate it.

[Kyle in NO]

Holy Jeebus that looks awesome. You are really planning this out thoughtfully and thoroughly.

[Mark 88/M5 Houston]

Impressive skills at work here!!

[e30isking]

Cool project... Using M30 crank?

[leadphut]

moar!

Thats some great plumbing layout for the space given. I really like how you have the wastegate tied in perfectly in line with exhaust flow.

Beautiful!
If possible I would try to raise rear to allow access to plug #6. I've changed a lot of plugs on mine through the years.
Your workmanship speaks for itself.

That's fine for an engine dyno, but I'm curious where you'll find a solid driveshaft and axle set made of depleted uranium.
A 1kw 7M creates so much torque it flexes the chassis, and the M30 creates more peak torque than the 7M at the same horsepower. Put it in a weaker chassis and I'm very curious to see a video of this at the dyno.

It would be plain stuppid to put loads of money and time into a M30 head when there is a 24v head available of the shelf which flows 3000 times better.

This 24v head wouldn't happen to be the S38 head, would it? You know that doesn't bolt onto the M30 block, right?
If there's another head, I'd love to know what it is. I don't really want to turbo a SOHC engine. Though I imagine if I port it really big, oversized valves, and a super aggressive cam, it might flow how it should on a high-pressure engine, but the same can be said for a 24v DOHC.

What ever happened to this?

Yes it does fit. My brother has it in his 537i turbo: M30 block, S38 head. But we only used this combo because the M30 block was already prepped.

I'd be very interested in how it was prepped then.
I've heard multiple accounts that the oil and coolant reservoirs don't line up from head to block, in addition to the obvious timing problems.

I have some wheels/tires for you, when you're ready.

Well, you heard wrong because a S38 block is basicly a M30 block. Only issue's where the oil return from the head which we made our selfs and the timing chain where we used the S38 timing components, this was basicly plug and play.

Which begs the question why there isn't a single documented build to be found. Just a few hypotheticals and second hand claims, and people looking to do this and being told it would require VERY invasive machine work on the block and head, the oil return, timing, compression ratio, and the bore doesn't match to name a few of the issues that I've seen.
Apparently you can mash certain parts, but not head to block.
An S38 swap looks to be cheaper than the fab work alone to get everything to work, never mind the cost of parts, and the end result would be less power than a stock S38 due to simply missing 200cc or so of displacement.

I'd be very interested in some build logs, if you made any.

What do you do about the bore/stroke? Or did you use an m90 block?

I keep coming back to this thread. It's better than porn.

Dear god, how did you fit that? I NEED to know. I'm knee deep in my project, and would love to run them.

[90e34535i]

Not sure if you guys know about it, but there's been a 1000+ rwhp m30 engine(1041rwhp) for a bit now:

And that manifold your making looks like art.

Daym!
Wish e30s could fit 315s. Maybe I should upgrade to an e28
