Bringing my dad's car back to its former glory and beyond

[AndryBismarck]

Very good looking car!!! Nice work. Your father lucky guy

Long time no see! Did some things to the E30:

• Smoke tested the intake tract- no leaks
• Cylinder 1 misfire code is now gone- Hooray!
• Vibration at idle remains- Boo!
• Bought LED bulbs for the headlights- OMG so much better

• Installed a new keyless entry- the fobs for the old one stopped working
• Bought a larger front swaybar from Garagistic on a whim because of their Black Friday sale. Turns out it was legit 1mm bigger than my current cabrio swaybar... :sadface:

• Tried out AKG 70A poly motor mounts- no better than the Revshift

• Moved on to stock E36 mounts flipped upside down- took some work but they fit

• Went back to stock trans mounts as well

• Modified the mid-section of the exhaust
  • Cut out the huge straight through Magnaflow muffler

• welded up the pin holes at the flanges- oh the boogers!

• replaced the old muffler with a 3" race catalytic converter

• Reinstalled the driveshaft tunnel shielding

• Exhaust sounds even better- videos to come
• She continues to make advances, albeit slowly and with much expense

Re: revshift and AKG bushings, was it just the vibration that you didn't like, or were there fitment concerns?

I liked my AKG mounts, but I understand wanting to dial it down a little

Basically my plan is to switch from CondorSpeedShop solid mounts to current (3rd gen?) Revshift 75A.
There has to be a noticable decrease in NVH from that, but I'm concerned about turbo/downpipe fitment since they seem offset to the right side of the car.

How do you find the E36 mounts? I'm running the E28 black cylindrical mounts and they move too much for my setup, are the E36 mounts sufficiently stiff?

The entire thing was about vibration, which even after going to stock E36 mounts still persists. That said, the Revshift mounts sat the intake manifold SUPER close to the brake booster. Maybe a couple mm from touching. The AKG mounts moved the distance to about 1cm away.

The overall difference in vibration through the mounts is definitely less with the AKGs and then even less with the stock e36s. I'm happy with the e36 mounts, not sure how they would be too soft?

With the mounts I'm running and the rear sump setup, going from the Alu M52 to S52 the mounts have sagged very quickly to the point where the sump will contact the subframe over bumps. Being a RHD too, initially I had enough steering clearance, but now that they've sagged I can quite easily foul the steering on left hand turns. I have a pair of 90a Revshift mounts but they're too stiff, the E36 mounts flipped looks like my next solution.

I'm also running rear sump and had steering clearance issues with the Revshift mounts (until I went to an aftermarket joint). Haven't noticed any sagging issues with any of the mounts thus far, but I have very few miles on them all.

I wonder if this why it wasnt as much as a pain for me since the Alu M52 is 50# lighter than the Iron S52
