FAQ:

Q: Is my S52 cylinder head ready for E36?

A: As part of the preparations for the S52 swap into my E36, I have to make sure the cylinder head for my S52 motor is well built and ready for boost. When I saw my S52 running in the E30 that is was pulled from, I could see a little smoke coming through the valve cover.

Q: What to do with a used S52 block?

A: Our used S52 block had some scoring in the cylinders due to the overheating incident so it quickly got sent to the recycle bin. In order to make everything go smoothly, Pure Performance offered up a block in trade for our soon-to-be-homeless M52.

Q: Is the S52 engine the same as the M3?

A: Here’s the crazy part of the M52/S52 family of engines, they all use the same iron block and aluminum head. Yes, you read that correctly; the S52 block from the M3 is the same iron block that’s in any of the 6-cylinder 3-Series models, as well as the same aluminum head. So what makes the S52 so much different?

Q: How much horsepower does a M52 engine have?

A: Our stock internal 2.5L M52, factory rated at 168hp/181 lb/ft torque… With the upgrades we’ve done; Intake and Software, Corsa Exhaust with M3 mid pipe, we’ve seen an increase of 10hp and 12 lb/ft torque totaling 150whp and 150 lb/ft torque, which all came from the exhaust upgrade…
