N52 Swap Discussion

Where's the Tesla booster? :P

Better? X3. I'm working my way up to Tesla.

With an EWS delete? I know Bob, and respect him well. But I had no idea he was doing swap support. Are you his first swap customer? Maybe it would be good if the two of us talked. :)

Cheers Nando.. am I right in thinking K-line is on pin 2 x60002 for the msv70?

I got it done through Bob at Stage FP and when he said he used a third party I suspected it was probably you. Will hook it up tomorrow and hopefully assess the mountain of codes that will be there

[nando]

For MSV70, you only need K-line hooked up. The calibration for swaps uses the E85 Z4 base coding, which doesn't use CAN for OBD2.

And actually, with the Z4 calibration if you hook up PT can it won't talk to the obd2 port at all, which is likely your issue.

Edit: all of this assumes you had your flash done by me, which I also assume because as far as I know nobody else has done it (not that I want to use my position to gouge people!).

Haven’t checked in on this thread for a while but you’ve really cracked on!

I finally managed to get my e30 to move under its new N52 power this week but I have a question about diagnostics/OBD2 which I’m sure you will also need to/have already figured out.

My donor was an early 330i but I understand D-can goes to pin 7 of the OBD from the body module/junction box. I obviously don’t have any other modules other than the DME so was wondering which signal needs wiring up?

At the minute I’ve got PT can going to pin 6 and 14 with a 120 ohm resistor between them but having connection issues with ediabas with multiple wires and a previously working installation.

Would appreciate some of the wisdom you all have!

I haven't had time to even think about E30s since the i3 master cylinder came in the mail. I still think there's an "easy" solution, I just haven't found it yet.

Since the thread has been so quiet, I have one new picture. This is the E46 M3 FPR. I fabricated a bracket for it and painted the engine bay while I was at it. Also Wilwood 260-12627 proportioning valve while I was at it.

So I pulled and weighed the M54/G260 combo out of my car today. 475lbs, and that's with 6Qts of oil in the sump and the heavier M56 metal valve cover, without those it would be closer to 460, which is within a few pounds of the N52 with GS6-16 6 speed (458lbs)

It's also missing the AC, has the lighter M50 intake and a small alternator.

I should have the final weight with new motor mounts and pan, but with the lighter N54 intake and A/C removed.

No groundbreaking updates. Mostly an opportunity for people to chuckle at MY welding. It sounds like Steve has his oil sump holding pressure. I'm waiting to borrow our sump closure pieces before I get too excited about mine. The whole think is seam welded, but I have at least three pinholes that I can see light through. This is the front corner of the "wing":



My pickup, tube, and expertly machined adapter look eerily similar to Steve's:



As does my pickup brace, which hasn't been zapped together yet:



The Rev-1 engine arms are nestled in the fixtures that I built from them here. Either side are the Rev-2 arms. On the port side (right side in the photo) the arm was widened to clear the center bolts to the block. On the starboard side (left in the photo) the arm was moved around 4" forward to clear some big tubey-parts that we might be adding on that side:



Here's the top side of the new starboard side arm... It's not as straight forward as the jump straight across to the motor mount, and unless you're looking for extra space for tubes I think Rev-1 works better. But hey. Some people like tubes:

What... ONE speed hole? ONE?!?

[hoveringuy]

Shouldn't we be on page 28 by now? hoveringuy where's that pickup, Steve!?!?

I get it. You want to make fun of my welding.

This started life as a Moroso #2480 pickup. There was some expert machining to turn the adapter bung and some minor fitting of the pipe.

Now that the pickup is done, I can fit the windage trays and close the open side of the pan.

Looks like there's two different versions of clutch slave cylinder. An early version that appears compatible with e30 clutch line and a late version that's plastic and uses a different fitting. Too bad about ditching the delay valve...

The e36 slave is also reported as compatible, p/n 21521159045
