Which 24v should I use for a swap?

[Mr Two]

Well, technically the best in the long run would be a 2.3L M50 from what I understand, as the block can handle the most boost.

It really depends on your power goals and if you want F.I.

Do some research, there's a wealth of information here, and on other bimmer boards.

An s5x isn't that much more if you are doing the swap the correct way. I spent 2100 on the engine and around 6k total, most of the cost is in the other stuff. I think people manage to do m50 swaps for so cheap because they cheap out on it.

the swap really isnt expensive to do... most of the important parts (driveshaft, booster, mount arms/oil pan, etc) can be had at scrap yards, and mounts, whatever seals are needed, etc, are pretty cheap.

M50 NV is the best platform in the longrun. For boost etc. If you just want some nice power off the bat. do S5x

???

i cant think of a single way that a nonvanos is the best in the long run.

The OBD1 M52. If I were to do mine over again I would do the M52 w/S52 cams.

I think the M52 being a 2.8 liter non ///M engine would be the better bang for the buck. With the money saved you could then boost it and make way more power than the S50.

I've seen two threads counting this one from you that could have ben answered by using the new and improved search function.

obd1 m52b28

I don't think I would go the s52/50 route because I would imagine they cost a lot more since they come out of M cars. So which model of M50 or M52 should I try to hunt down?
