FS: Metric Mechanic 11lb M20 FW + Complete Clutch Assy

[bmwman91]

Very clean, nice work!

[bmwman91]

Nope, zero chatter ever. It is a stock cast M20 FW and stock clutch, so it drives as nicely as one would expect. On the M42 / G240 transmission, it does allow for a bit more input shaft rattle versus...

[bmwman91]

Sounds good, they would know for sure I think.

[bmwman91]

As far as I know, this will bolt up just fine to the M42, M50, M52 and M54. However, the starter ring has the late M20 fine-pitch teeth (137) which will only work with the M20 starter (or pinion gear...

I am selling my M20 lightweight flywheel & complete clutch assembly. It all works perfectly, has effectively no wear on the disc or friction surfaces and has just under 40K miles on it. The reason...

[bmwman91]

TRUTH.

Back when I designed a full audio system for my car, the first thing I did was apply Damplifier to the entire interior + 3mm closed cell foam sheeting. The biggest improvement came...

I had a Wavetrac unit built by member Wanganstyle on here. The Wavetrac unit was built into a Z3 medium case housing since it is stronger and lighter than the E30 ones. It is one of the single best upgrades...

If you have a proper tune and a functioning / fresh catalytic converter, you will be fine. I've been passing the tailpipe sniffer with flying colors for nearly a decade with my 2.1L M42 (11.5:1 CR, hotter...

[bmwman91]

Interesting. Well, the next most plausible thing is what roguetoaster said about checking to see if the throttle is stuck open. That would explain the idle, anyway. It would not explain the rough running....

[bmwman91]

Good times, I use the same techniques with SMT stuff. Thankfully these face plates mostly use 0805 or larger stuff, or maybe 0603 here and there, which is really very easy to deal with. Magnification...

[bmwman91]

I am super excited to see this. The ABS performance on my E30 has always seemed a bit lackluster, and while I am not sure how much of that is due to these being "early" systems, I am pretty...

[bmwman91]

The only way that the M42 will idle at 2500RPM is if too much air is getting in. If you have no vac leaks, then it is most likely related to the ICV. When I was experimenting with some tunes, some maps...

[bmwman91]

Cool, take photos if you go that route. I'd be interested to see how it works out.

[bmwman91]

The car still has the AFM, with a cone filter attached, correct? The IAT sensor is 100% required to run properly, and it is integrated into the AFM, so unless it was chopped out of the AFM, ti is still...

[bmwman91]

Yeah, I had to cut out the inner "ring" in the HVAC panel's radio opening in order to get my RMT-200 to fit. It's what a lot of newer radios seem to require. A 3D printed mount plate is a good...

[bmwman91]

Original cat? If so, then that is your issue. A Magnaflow weld-in replacement should run you under $300 installed. I have gone straight from having one installed to passing SMOG with near zero numbers...

[bmwman91]

Dead engine mount? Other than the vibration, are there any unusual noises coming from the engine to indicate a mechanical problem?

[bmwman91]

Definitely provide that feedback, he should get it sorted out pretty quick.

Yeah, Dinan E30 tunes are pretty barebones.

[bmwman91]

Tach is driven by ECU. If it was not tracking crank position or speed, it would not run at all. I would run this observation by Sssquid aa it could indicate a bad flag somewhere in the code.

[bmwman91]

I feel you on the cycle of feeling like selling the E30, and then immediately changing the mind upon driving it. I also have had mine since 2005, and all sorts of trials & tribulations with an engine...
