M54 Madness, the remix

[hoveringuy]

It all seems to fit.

As a bonus, the sway bar is relocated to the front and the subframe is narrower, so fewer issues with the headers. Raceland, in this case.

Nice work by Tyler at the Arc Asylum.

Damn, this thing is going to be quick

Cams are installed.

The intake is a Schrick 264 degree/10.5mm. Stock was 240/9.7

The exhaust is a Shrek cam. 254 degree/9.7mm. Stock was 244/9.0

so it looks like you are almost ready to put it all back together???? Are you going to have it ready by the picnic?

Doubtful.

Still need to install cams but mostly I'll build a wiring harness from scratch for the Megasquirt. I could use the harness off the existing motor but it would be too much swapping around..

Upgraded oil pump shaft from Achilles Motorsports. No more nut to come loose and the shaft is tougher. They even pressed it into my pump rotor.

Pan is back from Tyler. I'll have an improved oil pump shaft today and then I can get the bottom buttoned back up.

I also have the cams. A Schrick intake and a Shrek exhaust.

Do you have any photos to show why?

Photos? No, but I work on e30's every day for a living and have replaced/welded stupid amounts of oil pans.

They last longer if they aren't the first thing besides a lip to hit something.

There are a lot of advantages to having a rear sump, specially in a swapped e30.

Presumably this is tyour e39 sump carved open?
Are you having the e39 sump re-worked?
Would it be easier to get an e36 sump altered (M50B25), as the oil pick up is then at the rear avoiding the cross support? - and presumably would be a straight forward fit into your e30?

Mike

You may be correct, but I haven't compared the e36 pan with the e39 pan. I can say that the oil pump and pickup tube is unique to the M54. The e36 pickup wouldn't work with an M54 pump.

Tyler has my oil pump and pickup tube and will need to extend the pickup slightly to clear the subframe.

I'll have more detailed pics in a few weeks to show his modifications.

Tyler sent and update with this picture.

[hoveringuy]

Update. Head is finally back from machinist and bolted back on. Machinist didn't do anything radical, but replaced the exhaust guides and completed a firs- rate valve cut. He also drilled the exhaust ports so I have 4 studs per port.

I have not yet installed cams because I'm going to hold-out for Schrick cams. Anyone have a set to sell me??

Next up is mailing the oil pan and subframe to Tyler for mod.

hello. Another M54B30.
I am running a M54B30 on the bmw 413 ecu with hoveringuys vanos board.
I have made a lot of changes on the board like controling the cam
angle from the ecu. I started with a TRM chip but never got it running
right. The problem with the TRM chip is the way he rescale for the
bigger fuel injectors. After i figure out the rescaling it was just
like tunning a megasquirt (i have change the code in the 413 ecu so i
have datalogging). Now it runs so smooth, idle nice with a light
flywheel. pulls hard from 2000rpm lose breathe at 6200rpm.
I am very happy with it.

I'll just add that I run with 540 MAF and ebay headers
