That blue widebody car that was at sema has an s52 turbo. It kinda looks small in the engine bay. But i dig how the valve cover looks in it. What part of florida are you from Albert?
The same gentleman who did Josh Stern’s S54 powered e9 has done an S52 swap into an e9. His name is Jeff Tighe. I spoke to him a long time ago about the S54 swap and he advised against it; basically said it was the wrong motor for the coupe (high rev’ving) . He said that the s52 is a better choice if going that route.
I had a similar opportunity not too long ago and ditched it. In part based on Mario's explanation in older threads about how hard the swap was into an E28. Note there is some difference in his thoughts between his earlier and later posts (which I'm having trouble linking): https://e9coupe.com/forum/threads/m3-engine-5-speed-tran-upgrade.3533/#post-20412 https://e9coupe.com/forum/threads/1973-3-0csi-conversion.5683/#post-34604

This was done recently in my area. Not sure if this is E36 or E46 M3 motor.
Will the S52 swap require reinforcement of the unibody to compensate for the added torque? Or will just a strut brace add enough rigidity?
Depends on how safe you want to play it, my coupe had stress cracks in the body running from the diff mount all the way in under the rear seats + the diff mount itself had shattered where the bushing gets bolted, and that's with the original 3.0. With a S52 alone, without turbo, I'd definitely go for the e28 rear subframe and diff paired with some serious reinforcement of the body. Add a turbo and I wouldn't personally want to drive it without a cage (for my own safety), not to mention brakes, steering, suspension, etc that would also have to be upgraded to really get anything out of the turbo setup except for just beeing cool.
With that said, I'd love to have a S52 turbo coupe
Mostly for the technical challenge to create it, but there's no way to do that legally over here..does anyone know much about this setup?

Here you have some photos of the pfaff kit, I don't know much about it but if you search the forum you might find some more info on it.
PFAFF Twin Turbo BMW 6 Cylinder System e9
SOLD This is a set of very rare vintage turbos and manifolds for an E9. These were built by Pfaff Turbo inc in 1981 and were sold by a dealership in California and by Dinan. These are very low mileage, have no shaft end play and spin up nicely with shop air. It comes with full set of new rods...
