Jason great stuff congrats. I can believe how appealing that S54 swap is. Makes the S50B32 swap look like ancient history. Euro engines are now so last year.
Any updates you want to share?
just got a package of AST 5100's, e36 fronts, z3 rears. new hubs, bearings, etc.
Also re-worked the rear subframe. I had the rear subframe lifted 10-12mm (which helped a TON) but I wanted to go up even farther. Mocked up a jig, and moved the trailing arm pickup points about 25mm. it just pokes through the rear deck. I am hoping to finish it up this weekend. will try to post some pics.
edit: forgot to mention i got a dual orbital last fall. had to try it on my not-so-shiney paint. wet sanded the whole thing, cut it, buffed it, then put it away.

New throttle pulley. Better than expected.
Converting to throttle by cable is NOT as easy as I thought. After trying 5-6 different pulley / bell crank systems on the original build, I finally got the pedal to feel good. (it looked ghetto, but it worked well.)
Fortunately for us, Alex has made some REALLY slick hardware.
Tip in is perfect. No on-off throttle!
Breeze to install, no interference.

Looking good. I'm glad I kept the FBW.
Last time out, I got a MAJOR engine vibration. I immediately thought it was the bearings. As it turned out, I distroyed the harmonic balancer. Apparently, the balancer should get a duct of fresh air to keep it cooler.
I found a good balancer, replaced it, much better. However I still get an occasional VERY slight vibration. Not sure if its my brain playing tricks or if the bearings got cooked. I am getting ready to run a compression test and pull the pan to check the bearings. Any insight? cheers, jason

This has been a known issue going back to the euro3.0 and 3.2. The long 6cyl cranks have all sorts of harmonics at high RPMs. I lost mine on my 3.2 which shook the flywheel right off the crank. I contacted ATI a little while ago, to commission a custom damper for the S54. They were happy to make one for me, but at the exorbitant cost of $800+. I told them that there was no way I would fund their R&D for a product that would later retail for 3 or $400. They said that they might consider a volume discount, but I wasn't willing to shell out for the 25 or so units it would take.
In the interim, we're stuck with preventatively replacing the OEM damper at the tune of $500 a whack.
If anyone was going to arrange a GB for an ATI balancer I would be on that list. I too looked into these but the $800 price tag was too much for the current budget.
If anyone wants to run with this, here's an alternate. We know what ATI will do for us, maybe these guys have a more favorable option:
Fluidampr by Horschel Motorsports
180 Zoar Valley Road
Springville, NY 14141
(716) 592-1000 phone
(716) 592-1001 fax
I believe there is a market for the product, I just don't want to be the guy to finance the R&D.
Is this damper thing a track car only issue or are all e46 M3's prone to it. First time I see that happen.
any high RPM six cylinder is prone to the failure. Usually track cars experience the issue due to sustained high RPM/ high heat conditions, but it could happen to a street car as well.
