Ever hear about condor speed shops mounts? They are quite cheap.
I just looked those up. For the price of AKG mounts, you can get both engine and trans mounts. I might end up going with these with AKG subframe mounts, since they're only $15 right now

AKG Motorsport has the subframe mount reinforcements. I have a set waiting to go in. I got pretty annoyed with the solid mounts on another car, but it wasnt a smooth BMW 6 so that may help out substantially.
What exactly bugged you? I know vibration annoys a lot of people, but the car wont be on the streets (that much lol) so it might not be a big deal

Launching the car was awesome
Cold idle made the car feel like it was going to eventually shake all the interior loose, and it made the B-pillar resonate at over 4000rpm.
If it was me, I would probably run a set of very stiff fail-safe polyurethane mounts (ones that will not fail catastrophically) along with the reinforcements and replace the mounts as needed. They are easy enough to change and are a better "weakest-link" than the subframe itself.
That is just me though. I am not as hardcore.

Actually poly mounts with reinforcements doesn't sound like a bad idea at all. Almost perfect actually. I don't want the inside of my car to resemble an earthquake, which is what I've been reading lol. Either way, can't seem to go wrong with the subframe reinforcements. And with brand new mounts I wouldn't think they'd have to be changed too often.

I run OEM rubber mounts for the engine + trans. I would say I probably gave the car a good 10-15 hard launches, 2 hrs of track time, and a handful of slidey corners this last summer and they are holding up fine. Clutch-kicks are another story. I don't do clutch-kicks but I think that is where OEM mounts would get really angry. If my OEM mounts last are able to last 2 or 3 summers between replacement then I will be satisfied. I do know that Bimmerworld sells a stiffer rubber mount that I may try next time.
I absolutely love the sig pic btw!

In that case I think I'm going to stay away from oem mounts then. Many clutch kicks and hard high revving shifts are in store. Last thing I need is for a mount to rip lol.
And thanks! It's actually going to be the "December" page for a British drift calendar... But that's a secret

Sure thing.
Woah, those are cheap. You werent kidding man.
Some more work tonight. Cleaned this guy up a bit. I wish I took "before" pictures, because it was literally black.
I might start scrubbing the block a little bit. Or I might just go home. Idunno lol

Something wrong with that?!?
Do you have a parts washer? I need to get my diff cover cleaned up and dont feel like scrubbing for an hour. I may end up taking it to a coin-op carwash.

No disrespect Rev Sharpton, and imma let you finish, but I had one of the blackest oil pans of all time

We have a parts washer, a sandblast cabinet that isnt set up yet (
), and my favorite.. wire wheel attachments. Which I did my oil pan with. Degreaser and wire wheel, which only took about an hour or so? The hardest part were the grooves. Youre welcome to bring that diff cover over any time. Except tomorrow. But any other time works. -
It was bound to happen sooner or later... and it has happened now. I am stuck. How do I remove this pulley/balancer doo-dad?
One of the major points of this tear down was to replace this timing cover seal because it leaks. This is the last thing to remove before I attempt to put it back together, and Im stuck. Haaaalp

Lock the crankshaft in place and use a breaker bar and cheater tube/lead pipe on the center nut.
-
On my E30 I put the car in gear, applied the park brake and used a breaker bar with a cheater bar. On my Camry I let the breaker bar wedge against the ground and used the starter motor to spin it off. Obviously these options dont apply for you in this case but be creative. I personally would probably get a steel angle (decent size, maybe 1" by 1" with some good wall thickness and about 3ft length. and drill 2 holes in it to where you could put the flywheel bolts back through it and secure it to the tail end of the crankshaft. Then have a friend hold that as you remove the nut on the other side.
I would avoid wedging anything internally such as a block of wood between the crank and block since the wall of the block could break-out, and I would refrain from holding the crank still by anything that is applying force to the pistons or connecting rods (such as inserting a wood block in the cylinder, resting the block upside down on the floor and having an obese friend sit on the block). Torsional reaction loading on the crankshaft is the safest bet.
