sub'd. Interesting ideas.

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.

hahahaha... Did they arrive yet?

Glad to see things are moving along for you man! Keep it up!

^They are here, cause I just went and checked the mail because of your post. They're preeeeeeeetty.

I also now have all of the pistons back in with fresh assembly lube. I guess I should go ahead and do the deed and order the gaskets and seals. Get them all in and sexy toward the end of next week.

Then I reckon I'll stick the tranny on and get the whole works into the engine bay so I can start getting the engine mount arms built.

Getting a little momentum.

Sounds like timing guides that have probably disintegrated. One of my M42s did something similiar when its timing rails failed.

I bet you will end up very close to being able to use a stock M20/G260 drive shaft...maybe have on on hand before you burn in your mounts and see if the whole drivetrain can be positioned accordingly? Obviously ensure that it isn't too far forward.

I would just like to acknowledge this post and generally agree with it.
:-D

I've never ordered from FCP Euro before, but their prices just seem incredibly fair, if not really good. I got that whole lot of gaskets and seals for $119 shipped. That's pretty much a full gasket set. I ordered the kitted bottom gasket set and individual top end stuff. Had I ordered the kitted top it would have been $150 total (including the bottom kit), and it came with valve stem seals and absolutely every gasket and seal for the motor. I mean, the head gasket was just $21 on its own. It is a Reinz, but foreals, that's fuckin' cheap.

Oh yeah, also, the oil pump sprocket from the newer e34 oil pump is smaller than the one from the old 735i. That means the e34 pump spins more per revolution (faster) giving more oil volume (and pressure?). So I'm gonna order a oil pump chain off of the e34 and give myself a bit more piece of mind there. It's 1 link shorter.

[Ether-D]

I just shot a quick email to FCP about adding the pump chain to the order I placed last night. Not 10 minutes later I get an invoice with the parts I ordered plus the pump chain added. I'm rather impressed with FCP Euro. At this point, I highly recommend them (no affiliation).

So I thought that while I wait for gaskets, I should go ahead and test fit some things. So I slapped the oil pan on and strapped that b34 up. Then I lifted it off of the stand and added a transmission. Then I rolled this little feller over to the patiently awaiting victim.







I gotta say, not having the core support in the way makes worlds o difference.





Rack clearance.





So, did anyone know this is gonna be sort a tight fit? jk lol smiley face.







I've got it in there at 1 degree steeper forward to aft than the angle of the m20 in my vert. So the rear of the motor is 1 degree lower than on the m20 car. Does that seem within acceptable limits?

Also, is it customary for the crank pulleys to be about a millimeter from the radiator?

Thanks fellers. That's it for today.

I'm thinking you're definitely going to have to massage that firewall a little bit. I'd be terrified to have the crank that close to the radiator.

I'm still waiting on the mounts I ordered for my m30 swap, so I don't know exactly how it will for, but I expect I'll have to hammer out space for the rear coolant pipe at the very least.

What radiator do you plan on running?

[Ether-D]

I have an e30 radiator. Figured I'd start with that.

So I'll have to "clearance" the tunnel a bit. I thought a couple of well placed blows would be useful.

[ThatOneEuroE30]

Lol it will be more then a couple. I had to litterly beat the shit out of my fire wall with a 5 pound sledge. A good 15-20 blows and the motor finally made it to the mounts. The head on the b34 had a rear coolant pipe on the head since that's there you gotta hit the firewall a lot right there. It's funny the guide says trans tunnel but I barley touched my trans tunnel. By the way I'm using QBANG brackets on revshift revshift motor mounts in the furthest back position.

[Ether-D]

Ok, I'll slap it around with my mini sledge tonight. How much are your motors tilted (on completed swaps)? I'm concerned with tweaking the guibo if I have it slanted too far down in the back.

[ThatOneEuroE30]

mines pretty level. which drive shaft are you going with? if you go with an 87 325e driveshaft I had to shorten mine and so have a few other people i know. from the pics i see your gonna need to hit the trans tunnel and the firewall but just a little on the trans so the top bolt goes in the tunnel.
