1990 BMW 325is S52 Swap

The S52-E30 swap makes a lot of sense to me, and I hope to some day try one out – if not own one. We’ve seen examples that range from Eastern Europe-y to So-Cal slacker, but today’s silver 325is takes a decidedly more subtle approach. Yes, it’s modified, but the E36 DS2s look good, as do the Alcantara centers on the seats. Overall it’s a pretty great package that, if the seller’s claims of no issues at all hold true, make this an exceptional E30. My biggest issue with this sale is that the motor came from an M Coupe, which makes me sad. Maybe that M Coupe got was totaled… but let’s just pretend it got an S62 swap. Either way, this seller took an opportunity and did an E30 swap right.

I love the DS2s in general but they’re a little large in this application. Some OEM+ 16″ wheels would keep this extra clean with a little more of a sleeper factor. On the other hand, whatever! This E30 has 240hp out a silky inline-6; maybe it deserves a little extra show. Wheel preference aside, this is a clean, well put-together E30 in the low-teens. The mileage on the engine and general swap nature would keep me from paying the full $15k Buy-It-Now.

    DDing an S52 E30 is a riot. I do it every day, and mine last time dyno’d at about 230HP at the wheels. This probably will sell close to asking price.

    Very nice. My only issue, and I see I’m not alone, is wheels. To me, they simply look not right on E30. Some nice old style BBS’s would do the trick.

    I actually think that the DS2s look better on the E30 than they do on the E36. Very sharp.
