Why would you go obd1 to obd2? I would do it the other way around. Obd1 has plenty of advantages.

Same question why would you do that? Obd I has great advantages to it not to mention no ews2 to yet in your way.

If you are putting a 99 motor in a 95 you don't need to make it obd II

im going to have 2 cars obd1 m3 and  obd2 i wanted to swap each otherbcuz i want obd1 in my 99 m3, and put the obd2 into the 95

So just make them both OBD1. Why even swap them is my question? Why not just leave them how the are? The 95 is a better car. It has better steering and a few other perks. Plus it looks better since I hate the facelift grills.

Cuz then ill have to swap my rotors suspentions brand new control arms i bought for the 99the and tie rods and sway bar links ect.. all brand new

[Earl]

That's a lot easier than swapping motors. That can all be done in a day. Lol

yeah i'd rather do every suspension part on the car than swap motors plus OBD conversion.....even trailing arm bushings OMIGOSH

i dont get it tho, how is a 3.0 better then a 3.2? im confuse my bad im a noob but thats why im here to learn.

I think they are mainly trying to say that the amount of time, money, and effort required to do the swap, even for the more powerful euro S50, isnt worth the gains you would get if you are purely just looking to go fast. That is up to you to decide if its worth it or not.

[Earl]

Exactly what he said. The cost of you having someone switch the motors, with the hassle of converting them from OBD 1 to OBD 2 (vice versa), would be a huge waste of time and money. The 95 has better handling characteristics due to a different steering rack and some different suspension components (bushings, front strut mounts, ect.). I also believe that an OBD2 M3 isn't that much faster , if any, than an OBD1 M3. To me the handling characteristics of the 95 definitely make it a more solid car though.

the s50b30 (the 95) and s52b32 (the 99) make the same HP (maybe a tiny big more TQ in the s52, but its negligible)

the s50 is 3.0l and based on the m50 motor

the s52 is 3.2l and based on the m52

both make the same power (240hp)*

*Side note: BMW is ghey for giving the U.S. such a puss motor both times.

call Dinan and see if the supercharger stuff can be used on the s52, and then swap it over. i'd imagine physically it would be fine, but you may need a new chip.

or, swap your suspension goodies.  both are easier than switching motors and converting OBDI/II

I thought most parts from the s52 are interchangeable with the s50
