How much for a m50 swap?

[plmichal]

Don't bother. The M20 is a nice engine and the M50 hardly gives you any additional power. I would not recommend swapping for next to no additional power, extra weight on the nose and all the work that goes with it.

I'd put in an M20B25, then. Seriously.

Seriously. I had a great M20 but it continued to snap rocker arms so I swapped in an M50. I'm glad I did it all because I learned a lot of valuable information, but it was NOT WORTH IT. I should have rebuilt the head on that car with the M20.

I'm speaking from experience man. Don't waste your time. If you want 24v, atleast do a S52. The M20 is a fantastic engine.

How much could I swap a m20b25 in it for and what could I do for extra power? Also how much do turbo setups cost for the m20? Is it worth it? I seem to see way more turbo'd e30's then i do e36.

Our stock 200k mile m20 with fresh head put down 154rwhp on the mce racing dyno.

i want to be closer to the 200hp mark, and an m50 with some s50 cams and other bits would do just that. I would just need to save some extra coin.

If you're worried about the cost to do a basic m50 swap then getting it to 200whp is gonna be out of reach. The easiest way to get (around) 200whp is to save up for a decent s50. Even a worked over m52 isn't worth the cost saving once you factor in your work.

Don't m50's have around 170 stock?

LOL, no it wouldn't. Real power power without spending a lot of money will be in the 170s. With the cams. It would be cheaper to put in an S50 than get 200whp out of an M50.

[Roysneon]

Probably not, unless it was very very well maintained. Maybe at the crank.

A local guy here had underdive pulleys, S50 cams, bigger injectors and a war chip tuned by a very reputable BMW guy, made 194 iirc.

Mid 150s.

[D-rock]

No I think its about 150

Just save up for an s52 if you want more power.

All of which cost approximately the price delta between an S50 and an M50 and made less power.

Cams: 350
Pullies: 200
WAR Chip: 350
Custom tune: minimum 200

Etcetera, etcetera. M50 swaps are a lot of effort for lousy returns.

If you really want an m50 (I think they're cool, regardless of the facts on power, weight, etc.) then go ahead, but if you want similar power cheaper and easier, I'd go with a decently maintaned m20b25. Use all stock e30 parts, no mixing and matching required and a lot easier. If you do want to turbo it some day, m20 will do just fine and are easier and cheaper to replace when the boost burns it up.

I always thought they were closer around 170 but if they are in the 150's then yea I'm just going to pick up a m20b25.

Is it possible to use the e36 LSD a well in the swap?

M52 will be close to 170rwhp with perhaps more torque if it has a fresh head and chip. Nothing beats displacement

S52 is ~220rwhp and worth the time if you think a 2800cc is not enough.

If you are experienced in domestic v8 usa car ring and pinion swaps you can interchange the guts from a e36 6 cyl into e30 housing case.
