The croissant bill alone is frightening!
However, once you put in that special key and launch it at 4krpm and feel the tires grip immediately as it catapaults you into hyperdrive, you know that its worth it.
Oh, ahem, sorry... Dreaming out loud again. Darn!
Dont worry. Thats almost exactly what AEHaas would say, but replace 5W-40 with 0W-30
Hey how is that BMW going? I had one many moons ago. Yours is a MONSTER!
Ever had an E30 with an S52US swap? (The 3.2L 333HP one out of an M. Pretty sure they called it S52US) :drool:

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.

1996-1999 US-spec E36 M3
1996-2000 US-spec E36/7/8 M Roadster/M Coupe
