    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.Ā 

        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.Ā

        $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 tuneĀ =P Ā 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.Ā 

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

                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

                                    True. Doesn't change the fact every sale ad should include an engine pic. Especially if you mention it in the title.

                                        I have never driven a swapped car so I can't comment on that part of it, but I think there is value in "doing it once" and getting the S52 right off the bat as they are only going to get more expensive.Ā No matter what you do with the M52 it will always be a little bit short of the S52 (unless you do an M54 rotating assembly), so if your goal is maximizing performance from an NA 24v, might as well get the S52 now versus wanting one later. If you can find a wrecked M3 for a reasonable price and have the time/space to take it apart, you can keep the S52/zf combo, part out the restĀ and end up with a decent deal on a motor/trans.

                                          I was honestly expecting more M52 votes. Extremely valid point about doing it right ONCE, which actually goes both ways. I could do an M52 swap right by refreshing everything and be able to get it together and driving this summer. To do the same for an S52 I may have to save my pennies andĀ shoot for completion next year.
