S54B32 swap?

Anyone ever tried a swap N52B30 - > S54B32 in e89?

Dimensionally I guess this should not be an issue as the late e46īs had both....

The E46 never had the N52. That said, it should still fit the same.

A supercharged S54 could be fun in this chassis.

other than the noise/sound, what is the advantage over a modded N54? with some mods and better engine cooling, N54 can be a monster

I agree. I have the same conversation with my buddies about V8 vs N54. The NA sounds nice, and has great throttle response but it pales in comparison to the FBO N54. Plus it takes a TON of cash to of cash just to get into the 400-500rwhp and still no chance to get any serious torque.

The N54 power band is much broader. If only we had better cooling and LSD from the factory.

I think Z4 is an expensive car for this kinds of swaps. I would go with old 3 series, less expensive parts, lower risk when you sell your car.

Well, I do NOT inted to sell my Zet... ever.

Yep, I am being conservative, but... I simply love the feel, nobility and linearity of straight 6valves, naturally aspirated. Maybe, just maybe Iīd fall in love with V8 or V10, but always and forever N/A....
