My M20 Swap

I just fallowed that DIY thread, and then added the flocking part onto it.

I have an extra bottle of the SEM-Weld if anyone wants to by it off of me.

Well... I got a few things done today. Got the front brake calipers and rotors back from a friend after sand blasting and painted them up in bright pink with yellow polka dots...

The engine is also technically in the car. I got the pilot bearings in the mail (in picture below old smaller one on top and newer bigger one on the bottom). I decided to put the engine in from the bottom. I just bolted the trans and sub frame to it, dropped the whole thing on two skateboards and slid it under the car. I guess tomorrow Ill find out how the trans fits in the tunnel

Exciting!!!

Keep that BFH on hand.

[Deutschman]

Oh I will! lol

[tinkwithanr]

Oo, that's gonna be fun. For some reason I thought you had test fit the trans before lol.

Hey! Engine in!!!

I need some help getting the engine wiring harness plugged into the right places. Any local SF guys want to lend a hand for free beer? I need some help from some one who knows m20 better then I do.

Future turbo space?

The 6 into 2 does go wiring directions are pretty good. Got everything but my tach going, and I think that issue may have been preexisting.

[Deutschman]

Ill check it out. I did print it out for my self, just have to find it.

[potentialm20]

If you can't find it I can send it to you.

[Deutschman]

All I can say is wiring is a bitch! Still working on getting everything hooked up. I hope this thing is running by the 5th! I have an event to go to.

Nothing new for the '02 but I got some swag for the 135i!

Now that the engine is in and I am wiring I have run into two problems. 1 the starter is not contacting the flywheel and just spins, and 2 the steering linkage is now not long enough to connect to the steering column even though it was perfect before the motor was in.

Im going to pick a 318i starter up on Monday. The steering linkage is a much bigger problem.

Got the motor to crank today! Now why dont I have any spark?

So the plugs I got from Blunt had the wrong sized nipples that did not fit in the spark plug wires. Right now I am running the spark plugs with out any of those metal nipples on them at all. Could that cause them to not spark?

[Deutschman]

On a little side note the girl friends car got the new wheels today!

VMR V718 wheels with some Hankook Ventus V12 evo K110 XL in 225/40ZR -18 front and 245/40ZR -18 rear. I am really digging it! Now the car needs some H&R sport springs to bring it down maybe an inch or so.

I am still having a hard time getting spark. The fact that I have a very limited understanding of how an ecu works and exactly what it does, mixed with the fact that the e30 engine harness is being mixed with a Painless wiring harness has me walking in circles right now.

I got a pin out chart of the ECU, so tomorrow I am going to start at the ECU and work my way forwards. First I just want to make sure the ECU is getting the correct ground and power. Ones I know that Ill work up to the wires that go from the ECU to the coil and see what kind of power they are putting out. Then coil resistance test, spark plug wire test, and points test. Man what a head ache.

I am asuming that the ECU dictates when the coil fires. Is this right? So if the ECU were bad the coil might not get power.

Does the coil get its power strait from the ECU? I think there is a yellow/black wire that goes from the starter solenoid to the coil. Man this shit rubs me the wrong way. So much to keep track of.

I know I have fuel at the rail. How does one check if the injectors are firing?

[tinkwithanr]

Correct me if I'm wrong, but doesn't a stock M20B25 have a distributor run of the front of the camshaft. If that's the case the spark should be controlled by the engine turning and not the ecu. I'm not sure how to check if the injectors are firing short of reading the signal with an oscilloscope. If I had to guess I would say maybe your ecu isn't getting power, which is causing your injectors to not fire.

Let us know what you find out.
