Want to do an M30 swap

[george graves]

Fucking christ... lol

So I need an eta manual tranny front half, of I have to pay $100 to have my 6 series front half cut down 2 inches...

Don't whine - I paid $250 for a e30 m3 shaft, then anoter $400 to have it shortened, rebalanced and rebuilt.

The auto tranny/ driveshaft has 4 bolt holes, the 5 speeds have 3.

As long as the front half has the larger flange on it to match the M30 tranny.
BUT
I hear that the automatic driveshafts have different mating surfaces, so it may not be eligible.

[euroshark]

And which driveshaft / combo did you use?

Is the 325e the right size and everything, or is a front half from an automatic necessary?

[rs4pro3]

I had mine in position three, getting the drive shaft on was a little tricky but doable

[Funkmasta]

Oh so an 87 325e has the bigger diameter input flange? Right now i have a 90 325i trans and front driveshaft in my 86 325es.

exactly

If you use the stock e30.de type II (e34/e34 engines) mounts, I used the position II and it fit, but didn't have that much driveshaft spline contact. It worked, but i didn't feel very confident.

Since i found it very difficult to fit the engine in position III, I drilled a hole in the middle of the two holes (position 2.5) and the engine fits more than a half inch farther back, the driveshaft fits much much better (stock 87 325e or 88 supereta DS), and the new engine position allows (3/4") breathing room between the radiator and the igniotion distributor unlike it once was in position II.

But it's more than position with the driveshaft. It's also the input flange diameter. You need the bigger flange which was coincidentally offered on the two models i just mentioned. you CANNOT use the 325i driveshaft. The tri-hole input flange was too small to fit on the output flange on the M30 tranny.

[JoeMadoo]

Oh, duhhh. Haha, what does that have to do with the ecu?

Also what position did everyone use that allowed them to use the stock ds.

[Garageaholic]

Cool thanks. What is the stock tranny called? Is it Getrag 260?

Sorry but what does acc power mean?

acc power means the power that's distributed throughout the car with 1 click/turn of the key in the ignition. Such as the radio, lights, stuff like that.

[JoeMadoo]

Thats ok, Im from victorville.

[Garageaholic]

mine too. easy as pie. no DS modifications and it handless the torque well

[rs4pro3]

I used the standard m30 tranny, and bolted directly in an 87 325e drive shaft with no modifications.

[pineapplegti]

Is there a way to use the older style spark plug wires and put the sensor on it instead of paying 50 bucks more for the newer set?

sorry to hijack joe but what part of the high desert are u in.. im in palmdale
