m42b32 Posted December 6, 2017 Author Report Share Posted December 6, 2017 Was out of town for two weeks and then didn't have any time to work on the car, but I finally got to my garage this past weekend and started tearing down the engine and got it on a stand: Got a bunch of unnecessary stuff stripped off like the AC and SAP, and pulled off all the accessories to start cleaning things up and get access to the oil filter housing. The donor car was hit in the driver's front corner and it caused the power steering reservoir to crack and dump all it's fluid onto the alternator, hopefully it didn't damage anything and I can just flush it out with some brake cleaner. I also did a test fit on the shorty headers, might have a problem as the rear manifold contacts the block slightly. There must be a slift angle difference between m52 and m54 exhaust manifold mounting surface, so I'll have to do some massaging. It might be easier to just get some M54 specific long-tubes.

Once finished, A dragster race between your car and Dan's car would be quite interesting. I'm definitely interested to see how they compare! That and I'd love to make a 1/4 mile pass or two, just for fun! Progress has been slower than I want at the moment, but once I'm past the new year I can start really getting into it Quote Link to comment Share on other sites More sharing options...
m42b32 Posted December 27, 2017 Author Report Share Posted December 27, 2017 E38 M52tu oil pickup tube on it's way from Europe, hopefully I'll have that soon to test it with the E34 oil pan. Fingers crossed it fits! I also finally have everything I need to properly order the adapter harness. This will integrate the drive-by-wire/OBD2/Fuel pump relays/Tach/etc into the E30 chassis and save me TONS of time as opposed to modifying an entire e39 body harness or messing around with making my own harness. My goal is to have this swap running as seamlessly as possible, but because I don't have a check panel, I'm going to skip the CAN integration, as all it would gain me is a working check engine light on the cluster.

It's the only front sump option that uses a similar oil pump to the M54. I've found info online that says it will work for this swap (and photos proving it will bold up to the pump), but they're usually in Europe and also have the E38 oil pan. Nobody could confirm if it works with the e34 pan, so I figured I'd take a chance and find out. I'm going to be ordering a harness from this guy: https://www.r3vlimited.com/board/showthread.php?t=275468&t=275468 I've been back and forth with him over the last few months and he is very knowledgeable, and has made quite a few of these. The cost is a bit steep, but more than worth it compared to the time saved. Quote Link to comment Share on other sites More sharing options...
B C Posted December 27, 2017 Report Share Posted December 27, 2017 So the E34 M50 pickup tube has a different flange then? What setup do most e30 guys do? Just convert to rear sump?? As far as the CEL. Take a look at the ecu pinout. If its like the OBD1/413 DME then its just a single wire for the CEL signal. Quote Link to comment Share on other sites More sharing options...

The CEL is communicated to the dash over canbus on the m52tu and later cars if I am not mistaken. There is an aftermarket canbus box that can be used to read the CEL over canbus and output to the light on the older cars dashboard.

Most people with an M54 swap cut and weld the existing rear sump pickup to work with a front sump like this: 3 minutes ago, jc43089 said: The CEL is communicated to the dash over canbus on the m52tu and later cars if I am not mistaken.

Since I don't have the check panel, cruse, or AC, the only thing I gain by having this $250+ module is a working check engine light. I'll have a working OBD2 port so I can pull that info from the DME that way, maybe with one of those bluetooth readers connected to my phone or something Quote Link to comment Share on other sites More sharing options...
jc43089 Posted December 27, 2017 Report Share Posted December 27, 2017 I have an OBDlink MX bluetooth reader, it was more expensive than ebay ones but it works very well. Logging is around 300ms refresh if looking at only one data point, I have read that the difference between good ones and cheap ones is the speed. m42b32 1 Quote Link to comment Share on other sites More sharing options...

Bassboy3313 Posted December 28, 2017 Report Share Posted December 28, 2017 I have a cheap ebay bluetooth OBD2 reader to talk to the Torque app on my phone or android headunit in the saabaru. Havent tried datalogging with it, but for just reading codes and seeing live data it works perfectly fine. Quote Link to comment Share on other sites More sharing options...
m42b32 Posted January 8, 2018 Author Report Share Posted January 8, 2018 Worked on this today now that the weather warmed up a bit. Against my better judgement, I bought some roll-center spacers from Garagistic since they were the only ones who still sell a 1/2" spacer (anything larger requires 17" wheels), and after fighting with them for over an hour, I realized that the hole pattern doesn't match up with the pattern on the struts. Not only that, but the ridge on one of them is too tall for the groove on the strut housing. I can probably enlarge the holes and shave down the ridge to make them fit... After I gave up on that, I went back to working on tearing down the engine. I am swapping the e46 engine harness to an e39 harness that will allow me to run the DME in the stock location, so I went through and labeled everything as I removed it to hopefully get it right on re-assembly. I also pulled out everything related to the CCV as I'll be converting it to a catch-can/pcv setup. Did a bunch of other random stuff as well, here's how it sits: Jdesign 1 Quote Link to comment Share on other sites More sharing options...

That's whats taking me forever since I have no good way to clean parts. The current method is to bring them home and scrub them in the bathtub haha. Can't do that with the block obviously... so I'll have to figure out something else there. I was thinking that since everything is aluminum I was just going to clean it well/leave it bare, and just paint the various steel brackets.

Jdesign Posted January 8, 2018 Report Share Posted January 8, 2018 Buy a case of brake clean. If you buy from Orielly they will price match farm and fleet @ $1.98 a can. KaiserRolls and m42b32 2 Quote Link to comment Share on other sites More sharing options...
The Full Banana Posted January 8, 2018 Report Share Posted January 8, 2018 I also found that NAPA "Aluminum Brightener" in a spray bottle does a good job of shining up aluminum parts, once the gunk is already off. It's pretty nasty stuff. m42b32 1 Quote Link to comment Share on other sites More sharing options...

m42b32 Posted January 8, 2018 Author Report Share Posted January 8, 2018 6 minutes ago, Snap said: What is the deal with that fuel rail? Air injection manifold? That's a vacuum distribution piece, basically just a secondary manifold that connects all 6 runners of the intake to the CCV system. It's disconnected and sitting there in that picture, it would usually connect to those 6 holes that are plugged with blue paper towel.

m42b32 Posted January 17, 2018 Author Report Share Posted January 17, 2018 Finally got my diff! It's a clutch-type 3.15LSD from a Z3M, I didn't get the finned cover (just a standard e30 one) but that made it much cheaper. Unfortunately, it appears that UPS dropped it on the input flange and destroyed the bearings. There is a ton of axial play, gear oil leaking out of the input seal due to all the slop, it's notchy to turn by hand, but hopefully there is no damage to the ring/pinion. Won't know more till I start taking it apart. Looks like I'll be learning to rebuild a diff Quote Link to comment Share on other sites More sharing options...
B C Posted January 17, 2018 Report Share Posted January 17, 2018 super sucky news! If it were me, I would pull the front cover and and look for tooth damage, then mark the input shaft nut/flange/shaft prior to removal, replace bearing, replace the seal, install the nut and flange to the same position as original, then you should be good to go. I would be very surprised if the flange ears themselves didnt bend but somehow the input shaft did. nothing should have deformed so the original nut position on the input shaft will be valid for setting it up again. m42b32 1 Quote Link to comment Share on other sites More sharing options...
Earl Posted January 17, 2018 Report Share Posted January 17, 2018 That sucks=/ It seems the safe way to ship a diff is to make a crate out of 2x4's Quote Link to comment Share on other sites More sharing options...
KaiserRolls Posted January 17, 2018 Report Share Posted January 17, 2018 Can you not file a claim? I received some shit from eBay that showed up damaged because it was packaged poorly. Filed a claim, sent it back, got money back Quote Link to comment Share on other sites More sharing options...
