Been a long time since I up dated this thread, since the last post I spun a being at the track, had the engine rebuilt. That's what the track is for, to break things. Over the winter got a chance to clean up some things that I fast handed last year just to get it on the road. The last oil analysis reported a lot of sand and dirt in the oil so I got rid of the K&N filter and picked up a real paper filter from a 2008 Mustang,

What did you put on the front lip?

 

That looks great btw!

You know I never liked that splitter that I made last year, it wasn't wide enough to reach to the sides, so had another go at it.

I'm going BOSOZOKOU ! :lol:

Made some new clam shell pieces to clamp onto the bottom lip of the air dam,

Hi Jeff,  I'm near Tottenham, north of T.O., have you started your build thread yet? We are all about the pics around here, can never get enough.

Edit, yes I found it, looking forward to your build.  If you are interested in more detail on the ///MZ you could have a look here, https://www.classiczcars.com/forums/topic/50240-thinking-about-installing-an-bmw-m6-engine-in-my-z/

Wow, that looks great!  Does it simply clip over the top and bottom of the lip and capture it?  I also have the same flimsy urethane air dam.

Yes, it's very simple or maybe even crude but it does keep the urethane air dam from bending at speed.

Okay so I'm dragging this one back out because big changes are happening, the S38 engine experiment was a success in many ways and in a few ways not so much. So I pulled it and sold it on BaT, wonderful engine but it is just not supported anymore.  I have rebuilt the e46 S54 M3 engine and that will be the new power plant.

So far the swap is going well, the engine is in, transmission and diff are lined up and the custom driveshaft is being built right now. I should have it back in a week,  next step is to have the BMW ECU re programed to eliminate all the extras that aren't needed and set to wiring it up.

I finally got around to making the top of the radiator support removable, considering how often the engines come and go it will be a big help, just have smooth it out, do some filling/sanding and try to match the paint. The original intake airbox sticks right out into the shock tower and also had problems with the #1 and #6  cylinders having uneven access to air so I have opened it up will try to fabricate a custom funnel to the air filter.

@carbuilder723, was nice enough to sent me the drawings for Ron Tyler's BMW engine mounts and after making cardboard mock ups of them I could see they just weren't going to work for my swap, not sure why.  So I made a couple of rough mounts and once the bulk of the work is completed on the swap I will take them off and clean up the welds and finish them a bit more.

Moving along, trying to get this swap finished before spring. 

I got the Silvermine brake kit installed, I ran into a couple of bugs that should have been worked out before shipping but all in all, pretty happy with it so far.

The stock plastic airbox elbow runs straight into the D/S shock tower so I had to come up with something to bring the fresh air in, this aluminum contraption might do the job but not sure yet. I haven't come up with a way to attach it yet so I'm open to suggestions.

The radiator is from  bmw M Roadster so a little narrower and fits well in the Z and with the Spal 30102082 fan I shouldn't have any cooling problems.

I couldn't bring myself to push those plastic cable ties through the cooling fins of the new Rad so made up a couple of braces to suspend the fan.

 

Kassel Performance did a great job on the PnP wiring harness, also deleted all the unnecessary programs from the ECU and added a tune that should boost the power, most of that is installed now.

I stayed with the original MAF for now as I don't want to spend the summer chasing potential problems with the CSL program, it seems some guys have no problems running the CSL program on these engines but many others can never get it right. 

The MAF will get me on the road the soonest I think and if more power is needed I can change over next winter.

I think I'm almost ready for spring, the new cooling system is in and the oil cooler, installed the "drive by wire" gas pedal(not thrilled about that but we'll see), the rad support cross over is finished now, exhaust system in place.

Just waiting on a fuel regulator to come from Germany before I can start it up.  Still have to hang the fenders, hood, grill, bumper and spoiler.

This is probably the cleanest this engine will ever be so posted extra pics.IMG_0604.JPG.745a0f163a5fb48de667894ce078bed6.JPGIMG_0606.JPG.79fcbfe2701c83a7b44d7a2bcb35c934.JPGIMG_0625.JPG.22c2343910501771a31e6f1cb8e18259.JPGIMG_0662.JPG.2d3b6a8c22deba2e7ac1aadc2a350a2d.JPGIMG_0652.JPG.06c2a60e49e8a3789413d32c4c8b0189.JPGIMG_0673.JPG.8198dfc4fe18914fba8d202278786865.JPGIMG_0697.JPG.9f40e5b3ab42862d730ec5d90c8c3e6f.JPGIMG_0698.JPG.f1bd439ade2d7f42f77a48b3612b5c3e.JPGIMG_0699.JPG.724f550762865f6cff4a43ebf2da7e17.JPGIMG_0700.JPG.0dcdcdfbd386032b65a9920edd8d2864.JPG

Looking great!

 

Is that an OEM part or some after market that you've plugged what looks like a water temp sensor into, that's attached to the radiator inlet?

Thanks, that is the coolant return to the pressure tank that sits where the battery use to be,  BMW makes a plastic piece that inserts there but it is known to crack easily so I turned one out of aluminum on the lathe and screwed a brass elbow in so no more fear of cracking.  The temp sensors are hidden behind the oil filter canister.

Of you don't like the floor mounted pedal z3's use a sensor that connects to a hanging pedal.  They are expensive new but should be cheap form a salvage yard.  Just make sure it's new enough to be drive by wire.

Hey, thanks.  I will check that out.
