[QUOTE="Vanquish, post: 151986, member: 84"] Thanks for clearing that up, E28driver. My apologies for the oversight. The S52 B32 engine was for the post 96' North American M3 models .... including the Canadian market as well. The S50 B32 was the engine found in all Euro and Asian market M3 models - itself an evolution of the famed S50 B30 engine. The S52 is essentially an evolution of the standard production M52 engine. However, it incorporates the following changes over its S50 B30 USA predecessor: -Increased bore to 86.4mm (from 86.0mm) and increased stroke to 89.6mm (from 85.8mm) for a total displacement of 3,152cc (from 2,990cc) -More finely balanced camshafts -Valve lifters, springs and spring seats with reduced mass -Revised intake and exhaust systems -OBD II (On-Board Diagnostics, version II) compliance -Horsepower unchanged at 240 hp (SAE) at 6,000 rpm ( this one pissed our American brothers much ) -Torque increased to 236 lb/ft at 3,800 rpm (up from 225 lb/ft at 4,250 rpm) Well, Dave - since you already have the hardware, it's best that you start talking to a few of the regular workshops that may have handled these sorta transplants. I'm sure you'll hear more from the resident piston-heads here as soon as they log in. Cheers, [/QUOTE]
