M30b34 E30 twin-screw supercharged muscle car

[Andy.B]

Your plan sounds like my plan. I've replaced the consumables (spark plugs, manifold gaskets, hoses, etc) for my m30 swap, but haven't bothered pulling the head, or even separating the tranny from the engine. I know if I do I won't be able to leave well enough alone, and it will take months and thousands of dollars before I have it running, vs just rolling the dice, installing it as is, and then making repairs as needed.

As far as the head bolts being reusable, I can't say for sure, but I have not once heard of stock head bolts that were reusable.

Also, anybody know off-hand if the m30 head bolts are re-useable?

they should be

edit: edit:

So I got my "full gasket set" in my cart at fcp euro with:
Head, valve cover, water pump, timing cover, exhaust, oil pan, intake, and thermostat housing gaskets
And cam, timing and rear main seals.
All for $110. That seems like a deal.
No drippy.

Alright. So should I buy the upper and lower gasket and seal set for $150 and just put this motor back together? Then rebuild it later if needed?

Or buy the Maxsil Piston kit from bavauto with rings for $584 and go ahead and have it bored and put all back together all new like?

The difference is basically a delayed project start time and more out of pocket on the upfront. If I go ahead and put her back together, then I can get to engineering the supercharger and get the ball rolling on the whole thing. But maybe have to re-buy the gaskets later if I need to rebuild.

If I have to buy pistons and have the block bored now, that will be mo money which means mo time before I can get to gettin', but it also means I won't have to do a rebuild later.

It helps me so much just typing this shit out. I think I'm gonna do the quick and dirty start plan. I wanna get some damn motor in a damn e30 already. If I need to do a ground-up rebuild later I will.

Nice riiiiight?

[Ether-D]

Got my oil pan and pump from the e34. Thank you Red88! It's nice and clean, and was well packed and shipped quick.

Got the comfy polly motor and transmission mounts ordered and on the way from G-man the visionary. Thank you too sir! What a wonderful communicator! I've heard he smells of fresh baked bread. I cannot confirm this.

I ain't gonna do one of those remote supercharger mount jobs. I really like the manifold-mount variant, and the water pump is right where the snout wants to be. There's also coolant hose(s) near there in the way.

Anybody (slammin) know if I should hone the cylinders and re-ring it, will it be worth it? Or get the Maxsil pistons and get it bored at the mech shop. Or just hope for the best the way it is and fuck with the whole rebuild later (or not at all).

[slammin.e28]

Also, logistically, this motor is gonna be heaps harder to supercharge. That damn water pump is slap in the way. Can one use an electric water pump? I kinda wanna cut this one off to make my fabrication a bit easier…

Whuut?

Shouldn't have to do anything to the WP on an M30 to slap an Eaton on.

Interested to see your plans.

Alright I pulled the head off of the b34 cause I just had to know what it looked like in there. And I found something I'm not too keen on. One of the pistons had a pretty good sized gouge in the outside edge. I can only guess something crazy happened and a valve hit a piston (or two, see pics). Maybe a valve broke off or the motor ate some gravel or something. There is a bit of a chafe on the cylinder wall corresponding with where the piston deformed when the gravel, valve, denture partial was consumed. The exhaust valve on that cylinder was also the only oily-ish one in the lot, so I reckon there's a bit of blow-by in that cyl. I think that I'm gonna be ok with it all though. What's a little blow-by in the grand scheme?

This m10 clutch can handle 283 hp and 291ft/lbs and is $146? Does that sound right? Seems cheap to me.

[Ether-D]

Removed the timing cover(s) and looked inside to see that it has a new timing guide on the tension side and what looks to be old on the slack/spring side. I managed to mangle the head gasket where it continues on to in-between the two timing covers so I'm gonna get one and just replace it while it's easy. Hell, I might just do all the gaskets and shit while it's on the stand.

Btdubz, does anybody know how similar the m10 and m30 are? M10 just looks like a m30 minus 2 cylinders. The oil pump chain is a bit smaller on the m10, but a lot of stuff may cross over. I think I've read that the rod and main bearings are the same and rods and such.

Got my steel for the mounts in the mail, and ordered an oil pan and pickup from a e34 from Red88 here on r3v. Creeping forward...

[Ether-D]

Ok, so, I took out the timing chain tensioner and the grinding noise stopped. Now it turns over all smooth and silky like. So I reckon that means I need some new timing guides. No big whoop.

I'm interested in this. I may could want the whole motor/trans combo if it doesn't already have a home.

Yeah, you got a good brother. He's a damn good dude. And I right like Donnie as well.

The car is at a junkyard, so if you were really interested then we will pull it. 5spd for sure, but the motor would depend on if the yard will help us get the motor out.

On that note, I can also get some ellipsoids (not perfect), black leather e36 seats already mounted in the e30. Houndstooth coupe door cars and the rear houndstooth seat. Eibach springs but those may hard to remove.
