Bronzit E30 - OBDII S52 shaved bay - weekend/autox toy - Journey

Hey, I am going to recommend the high volume vac S54 oil pump.

Save you some time, and noisy lifters..

And for good lord, use the AKG swap mounts with Rouge trans mounts. Those Delrin rigs with buzz bomb the car apart. :)

I seem to be having fitment issues. Angles don't really line up. I followed AKG instructions. Set everything up loose. Still sits wonky.

Well for most swaps, that means a little extra room for a brake booster.
You have a chassis-mounted shifter, right? Does that setup have enough play to allow for the engine's shift? (pun intended)

Yea shifter will be fine. Ill probably have to adjust it though.

akg mounts shifted the engine about 1/2" to the passenger side

5lb flywheel, and what's the clutch pack weigh? I bought the lightweight kit from UUC and I was warned that the transmission would rattle due to less inertia, and they were right, the damn thing rattles every day once the car warms up. They said to fill up half the trans with a quart of thicker oil (I don't remember which exactly) to reduce the rattle. It's still pretty annoying. But it will stop once I press the clutch in. Kind of makes me think the TO bearing is junk.

So I'm wondering, do you also have that problem with a lightweight setup? Transmission rattle when the car is idling?

The whole unit is ~18lbs. And yes it rattles and vibrates like a mofo. Pushing the clutch in also quiets. Doesn't sound like anything wrong with your setup, especially if you don't notice any performance issues. Ive literally had a few people warn me that "my car is broken" Ha!

Sounds great. Turbo/WG/downpipe is all super tight, so any info you can gather on position delta would be huge.

Forgot to include I'm on a cheap-o FX racing ""stage 3"" single mass/6-puck/Sachs HD setup. Lighter than an M20 flywheel but nowhere near 5lbs.

Ill report back with some review.

I also have ball jointed control arms. But running a normal guibo, and 5lb flywheel (clutch masters small twin disc).

I had the FW/PP balanced before install but they didn't remove much.

So this whole oil pan repair has become quite the project.

It has snowballed into replacing the power steering pump, fuel lines, engine and trans mounts.

Ive known my power steering was dying for a long time. Its the second used zf pump. New ones are NLA. Last time I tried to buy one there were no options. This time I stumbled upon a new AAE unit offered through bimmerworld, so I'll give it a shot. I also saw rockauto offers rebuilt units.

I run Condor engine mounts/stock e30 trans mounts, and besides the most minor vibration through the wheel at idle, it's only really noticeable if I bog the engine (keep in mind THR eyeballs and solid steering guibo probably make it worse than the mounts themselves.)

That said, I have some logged knock at light load areas, which doesn't make sense unless it's false knock.
Maybe electrical, maybe noise from the mounts and I really have no way to tell other than trial and error changing mounts and whatnot.
So I bought the newest Revshift mounts, and while I'm a huge fan of Revshift's bushings and other mounts, I can't run these mounts because they move the engine further to the passenger side and I don't have room to do that (The claim is that they 3d scanned original/24v swap configuration and found it needs to move further to the right, I guess due to the increased lean angle?)

So I'm mentally preparing to buy a set of AKG at some point when my car is closer to the road, but they historically have spent way more time sold out than available. Probably why you didn't buy them originally, and was why I ended up with the Condor mounts as well.

Yup you are correct. I found my emails requesting lead time a few years ago. Got lucky this time around and got my hands on a set, along with their matching Trans mounts. Ill report back with some review.

The S54 uses a different size sprocket and volume pump. The "High volume" setup just puts the M50 pump gears inside of the S54 housing, so your ratio to pump volume will be back to normal.

Yea I remember the general mechanics of it. At one point a few years ago I was going to try to have a local machine shop machine the pump cavity, and the I'd just stick a spare M52 pump gear in it and save myself the $1500 VAC charges. But I don't have time for that, and am out of budget for this unbudgeted project. So I hope it won't be too bad for now. Maybe I'll try to source another used s54 pump and have it machined to be installed at a later date. I also stripped a bolt going into the rear main seal housing at the back of the pan. So I may already have a reason to open it up again in a few months.

Are they that bad in an E30? I used condor UHMW mounts on the engine and their poly mounts on the transmission of my E34 and it's fine as a DD even with the all aluminum twin disc setup. S52, 3L M50 stroker, vibration wise they're the same engine. Granted for me it's 100% necessary because of how little room there is for the engine to move and I'm making 2x+ S52 torque.

I'll let you know in a week. Just ordered the AKG mounts. I don't think it's that bad, but yes it is a bit buzzy and I do get some vibrations at certain RPM.

I recall ages ago I was trying to purchase those exact mounts - both the AKG and rogue for the same reason (less vibrations). I don't recall why I didnt. Maybe they were out of stock and I was impatient. Ill see if I can order and receive them quick enough to change them out now.

Regarding the VAC pump upgrade... is it really that needed?? I spent too much on this side project already. That's another $1500+ 😭
