LS1 / T56 DD e28 BMW Build

[HighOnLife]

Damn Jake that wiring looks intense!

Looks like a killer project, +1 for keeping AC

New muffler came yesterday....I was able to gain 2" of ground clearance. There is about 3/8" between the driveshaft and the muffler. Debating dropping it down a little bit...The driveshaft can't really move tho...

What do you all think?




Here is the clearance to the drive shaft. Sorta hard to see but there is about 3/8"



I got the centers back from the powder coater. I am very happy with the color choice.


Got sot some mesh wrap for the harness.

I am able to adjust the exhaust up and down maybe 1/2-3/4" each way so if I end up being too close the to driveshaft I can lower it down a bit. Added some more tack welds to the exhaust and took it off the car before I weld it all the way.





More wiring done....

Wiring coming off the TPS and IAC


Alternator and PCM coolant sensor


Wiring routed along from the injectors, coil, evap valve. Tapped anytime a wire comes in or out of the bundle.


Goes along the back of the engine...you can just see the wires coming up from the trans (O2 sensors, VSS, reverse lockout). Then it picks up, oil dummy light, cam sensor, maf, knock sensors.



From the passenger side...You can also see the crank sensor, coolant gauge, and starter wiring coming up into the bundle.



Passenger side bundle....it's getting bigger. Picks up the other injectors and coil wires.



Here you can see the wires started to be plugged back into the PCM in its new location. Some of the wires are too short and some are too long. The short ones will have to be lengthened of course but I am debating shortening the ones that are too long.... Some are up to 12" too long and I could sorta fold them back on themselves in the bundle or I can shorten them..... Any suggestions which way is best?



All connections of wires have been soldered and then covered in dual walled heat shrink. Inside has a adhesive that melts and bonds to the wire to provide moisture protection.

The rest of the AC parts will be here tomorrow so then I can finish the AC pressure sensor wiring as well as the MAF/IAC wiring.

If anyone else is doing a similar swap and needs harness work let me know. I really enjoy this step.

I was hoping it would be running next weekend but I am guessing it is the following. One of the problems I have is when I start to see the end of a project I almost don't want it to end...it's like a really good movie.

I think it should be ok if the exhaust is close to the driveshaft. As long as the exhaust is very secure and wont bump into the shaft on a hard bump or vibrate on a brick road tapping it or something like that.

Wow very cool build.

but an E28 roasting its tires through 3rd would be a great ending to any movie

3/8ths might be cutting it close especially if the torque from the motor twists/shakes the exhaust around. Id just run it as is and if you do run into any problems, you could add 2 flex pipes up front and solid mounting the rear section if it does later down the line.

Cant wait to see this thing in action!

There is a wind storm here today and the school I teach at lost power so I ended up with a half day.

I had power at my house tho..
I was able to get the exhaust all welded up.


The rest of my AC parts came today....and once again one of them is wrong. The company I got them from knows what they messed up....new one should get made and on the way. But the part I needed to be able to route all the lines was correct so that is good.

A couple AC line pictures..still need to be crimped




This is the part that is wrong....for the second time. It should have a #8 beadlock with a high side fill port. This one has #10 and a low side port.


Started plugging things back into the PCM. Lengthening or shortening by soldering and covering with adhesive lined heat shrink. Matching wire colors as close as I can get .

[e30_neverstock]

nice work. cant wait to here this thing run.

[Schwarz325]

awesome project man! very nice work.


More info on the little fiat 500 (or whatever) that is back in the corner

[dirtysix]

This thing is fucking sweet.

[jakeb]

It is a 1960 Fiat 500... very rusty project I bought a few years ago when it popped up locally. It is a project for another day....maybe in the next 5-10years. Maybe sooner...but more than likely not. If I can find some time this summer I may try and cut out all the rot and brace it all together.

I bought a 67 fiat 850 spider last summer to use the engine and trans in the 500. I am still unsure if the 850 engine is going to be enough power so I have thought about turboing the 850 engine or ditching the 850 engine all together and using a VW trans mated up to a subaru flat 4....

Here is a link so some more pictures of the fiat and its rust.

A small update...been busy with life and I haven't had as much garage time as I like. Wiring is ALMOST done. The engine harness just needs to be wrapped and the chassis to engine needs to be connected at the GM fuse box and then some wires routed inside. I took this friday off and plan to get all the small things done and if all works out I will be firing it up. HP Tuners is in route so I can pull off all the unneeded stuff from the PCM.

Some pictures...



Where the engine harness will connect to the chassis side.




Wiring that will go into the cabin.... econ gauge, tach wire, check engine light, OBDII port, 12v (switched) 12v (constant), ground, and also 6 wires if I ever want to connect my wideband.





Where it connects to the BMW fuse box.



You can see how the AC lines will route and hook up to the drier here.

[slaterd]

too...many...wires...
my head hurt now

[The Volta]

I am so excited for this car, makes me want to pee my pants.
