The One That Didn't Get Away [100K Mile E30 325is]

My vote is MS2 pnp. Not sure if they made an MS3 pnp for the m20?
-
Here is how it will play out: you grab a bimmerheads ported and polished rebuilt head with a cam, attach some ceramic coated headers while you are at it, Drop that in sometime in June. then work on a stroker bottom end build and preparing for MS2 over the winter.
i kno, rite?

Orrrrrrrr, k24 swap it & add cams. Better weight balance, more power, wasn’t brought to the US on the mayflower, etc.

245hp at the crank after playing with the smoothing and correction factors, deleting the lot of 237bhp plots that preceeded it and dry-icing the intake.

I honestly wonder what the cost difference would really be between building the M20 already in your car vs swapping a K24. The adapter plate is like $1500 alone.

Oil pump location on the K motor is right in the middle of the subframe on an e21/e30. Not that it can't be done, but it's not pretty and there is some fabrication involved.
Luckily kmiata exists and takes the headache out of the swap. The e30 k swap is much simpler than the Miata k swap.

I'd rather stay with the M20 platform at this point.
My original point was with the time/cost you’ll sink into a high strung 3.1L m20 would probably be close to putting a k in. Not to say the K is a cheap swap, but neither is building a motor.
that being said my vote would still be do whatever you want because a high strung stroker m20 sounds sweet

Completely understand, it would definitely be a pricey build. I very much like the idea of retaining the M20, while being a modified variant, would adhere to the vast majority of maintenance, repairs, and trouble shooting sequences for a normal M20
I vote m20 stroker because it is OEM + and I am all for OEM +
I agree.

With a car as clean and low mileage as yours I'd definitely be inclined to keep the original engine. There is absolutely no shame in liking an M20, they're pretty hard to hate! I'd love one to play around with again at some point.
I totally agree that M20's (and the M30) are some of the best sounding BMW engines too, anything newer has absolutely nothing on them.
The M30 is one of my favorite engines and I would absolutely buy a 535i just because of that but I also take exception to that last sentence...

I'm glad to see the boat anchor is still going strong in this group!
I think doing any engine swap on this car is dumb.
It is a low mileage, low owner vehicle. While I do believe you should enjoy the vehicles you buy, I think if you wanted to build something swapped I would sell this one and build it off the profits. -

Correct
Though that thing has been bouncing around like a bad case of VD.
Not that I helped the situation any! -
Here's my YouTube click baity post of the week. Going to be picking up something for the car in Madison this weekend that I kind of fell backwards into. Something I've wanted for a long time, and, even appears to be the same color as my car. Also a great deal that I couldn't pass up.

I was thinking 6 cylinder engines. Anything v8 isn't a fair comparison haha
