My E30 M50 Swap with pictures

Woops, just realized that "D" is not the 02 sensor, it goes to the MAF.

So im guessing that "A" is the 02 sensor then.

[nholm325e]

A: Blk, Brn, Yel, Grn ??

B: Grn/Wht, Blu/Yel ??

C: Brn, Red/Yel Reverse Lights ??

D: 02 Sensor (The one i purchased off Ebay, the 02 plastic connector is a female, and the engine harness is female also, and they are both shaped differently) I checked the ebay auction, and i deff. purchased a e36 325i 02 sensor, so maybe they sent the wrong one..

Not really sure what A, B, and C are exactly for...??

Where do i buy the wiring troubleshooting book(the wiring layout schematics or w.e.) for the E36??

[nholm325e]

alright thanks

Whatever you do with the driveshaft you need the proper CSB for your chassis. It will fit on the e36 driveshaft.

You can use the e30 driveshaft (I am) but you will have to extend it at the splines, and it's still slightly too short.

Use the e36 guibo either way. With the e36 driveshaft it will be perfect. With the e30 driveshaft, the bolts will wiggle around in the holes, you can buy bushings to fix this. (or just deal with it, which is what most people do.)

Thanks for the fast response, im trying to figure out what i need to get because i gotta get ordering

so because i have the post 5/86 driveshaft that means i should just use a e36 325i manual driveshaft and gueibo in order for everything to line up and fit??

Or should i just get the smaller gueibo, use different bolts and rig up something for that 1/2 inch gap ill still have??

I keep reading your guys posts im just making sure im following you guys right, Thanks

If you have a post-5/86 eta, then your driveshaft has a larger guibo (96 mm BCD) than the Getrag 250 can accept (78 mm BCD). So you will need a 325i manual driveshaft from either an E30 or E36.

The e36 one fits better. The e30 one has the wrong size bolt holes for the e36 guibo. It's also a little too short (as you already know)

I thought the "getrag" transmissions only came stock on the m20 engines. I thought the m50 engines used "zf" trans...guess i was wrong

Anyways mine is a getrag(doesent look a thing like my old e30 trans) and i noticed when i was fitting my e30 guiebo on that it just rubs the bottom of the shift linkage and also their is about a 1/2 inch gap still between the trans and driveshaft after i slide the guiebo in.

--Am i sapose to use the e36 guiebo and are they thicker and/or smaller in diameter, or do i have to do something with my driveshaft??

ehh, well i havent driven my car in over a year and im gettin a little excited. Im more concerned with fixing all the little problems and getting all the kinks worked out before i waste my time cleaning. Gotta keep priorities straight...

Plus im gonna boost it this winter, so i gotta tear most of it down anyways so i thought that would be a perfect time to start doing alot of cleaning, painting, and the rest of the final touches sense the motor will be out again anyways.

Its deff. gunna be show car material by spring..
