    i had to vote for S52, but I couldn't help myself. If I'm gonna have a modified car, I like taking it to car places and having something more unique that will create conversation with people. I think the S52 swap ticks that box a lot more than an M52. I tried to be objective about it for your sake based on your situation as you have described it, but honestly if the difference here is $1000 or less, then the S52 is actually the real no-brainer option. It's faster, more unique, and will make the car worth significantly more than the difference in financial cost between the 2 motors. 

    If money is an issue I will help you buy the motor and you can pay me back. 

    It is faster and cheaper to do an M52 (faster because you can source one locally right now and you may need to save money for longer if you want an s52)....but I just think if you are going to do a swap, you should go all the way and do a proper S motor.

      M52 with M54b30 crank is always an option? 
      Cheap way to get more displacement out of an m52.

      ...

              I know nothing about E30s or their market with non-factory motors in them.

              $1000+ for a measly 20whp is not money well spent in my opinion.

              PS: Put an N54 in it.

                however, his car will be worth at least $1000 more in the end, if not double that. (if that is an important factor to him)

                  exactly. 

                  S52 is the way to go especially if a parts car with engine, harness, and trans can be sourced - they usually don't go for more than $3k which is well worth it.

                  $1000+ for 20 whp is not money well spent to you because you're used to turbo cars where 75 hp can be gained with a tune =P  In the world of 200hp NA motors, 20 whp is a lot especially across the entire power band.

                    No replacement for displacement!!!!

                    Any S-motor is an upgrade in the eyes of an E30 buyer. 

                    For FI the M52 is a better choice leaving $ in the budget for a spare.

                      I vote s5x, or at least an m52 with M power valve covers

                          Makes me wonder how many M52 cars with S52 cams have been sold as S52 cars and how many S52 engines have been sold with M52 cams. Are there any markings on the block?'id thin there would have to be a stamp

                            Yes and no. Heads I believe are all casted the same (?)

                            Block should have markings

                            If not the vin is a give away "WBSxxxx" is ///M and "WBAxxxx" is non ///M iirc

                                          Thats a nice find, Earl

                                          Ive made offers on 2 cheap M3s but the sellers are holding them for other buyers.

                                          My friend in high school was told his E30 325is had "an M engine" when he bought it, hopefully this seller isnt also that mental
