E30 Zone

Hi all
i currently have a m52b28 in my E30 and i was wondering would a M50b30/M52b32 head fit on to my block?

Thanks

I think you mean an S50 B30/B32 head. The answer is no

The US M3 engine (S52B32) Is basically a stroked M50 motor, but don't think the head is any different to a normal M50, or if it is then it would be work you could do to your current M52 head

S52B32

This engine was sold only in the USA and Canada and is closely based on the iron-block USA-spec M52 engine. It differs in having an 86.4mm bore and an 89.6mm stroke for a displacement of approximately 3.2 litres. It shares very few components with the European S50. The S52 is essentially a large displacement M52 with minor upgrades to increase performance. It uses a regular M52 head with the same stepped VANOS system (on the intake cam only) but uses more aggressive cams. The intake manifold and throttle body is from the M52B28. The exhaust manifolds are the same between M52 and S52 but the S52 uses special muffler designed by Boyesen that is less restrictive. Even the connecting rods are exactly the same 135 mm units used in the M52B28. The lubrication system on the S52 is optimized for greater flow. Engine management is handled by the same Siemens system as the M52 but is tuned to the larger displacement and slightly more performance biased.

Physically, there are very few external characteristics that distinguish the S52 from its M52 brother. The "M-Power" valve cover is the easiest to spot although it must be noted that S52 and M52 valve covers are easily interchangeable. A more subtle difference is the oil filter housing. While the M52 uses a threaded black plastic cover on its filter, the S52 uses an aluminum cover held in place by a bolt. This is the same housing as was used on the 1991-1995 M50 series engines. As such, the S52 uses M50-style filter cartridges instead of the M52 style. Power from the S52B32US is officially quoted at 240 HP but many[who?] feel that this figure is understated. Maximum permissible engine speed varies from 6500 rpm to 6800 rpm to allow a margin of safety for the hydraulic lifters and the rest of the valve-train, although the engine can safely rev to 7000 rpm.

The advantage is the cams and an m3 cam cover

Very true, and a lot cheaper than schrick cams, but I wonder how much benifit the schrick cams offer?

I currently have the US M3 cams in my 2.8 i was just wanting a way of putting M3 throttle bodys on my M52B28. Is their any other way of doing this?
Thanks

By the way Andy you know your shit about these motors

M3 throttles will need a custom adaptor plate making, complicated design. Also an S50 oil filter housing and a proper remap as the vanos engine will run like a bag of shite with standard maps

I already have a s50 oil filter housing, and i use a vems ECU so that wouldnt be a problem

Whats the benefit of an s50 oil filter housing?

And I want some s52 cams for my m52
