S52 head on a M52

[Bimmer_man]

I have been looking to see if a S52 head can fit on a M52. My moms 328iS E36 is leaking coolant and one of the possibilities is a blown head gasket. And if thats the case i was going to get my mom a new head and give her more HP. Can the S52 head just slap right on a M52 block or dose it need a lot of new crap on the bottom end?

I don't think just swapping the head will make any more power unless you include the entire valvetrain. In any event, do some research, but I believe the head swap will work without bottom end work.

ive been trying to do some independent research but all i keep seeing is M54 stuff with a S52 and visa versa. I keep looking though. But the whole valvetran will be from the S52. Maybe a cam er something. Definatly some port and polish work.

heads are identical

Different cams valve springs and seats, but otherwise the same.

Well that's nice combine that with a obd1 intake and the car should make more power too sweet.

Your mom is going to be thrilled with all this new power.

[Bimmer_man]

Can't be much more power like 20-30hp right?

I think she'll probably just want a turbo setup.

Definitely needs a supercharger.

[10Toes]

and some NOS too, and then you will have to get her some stickier tires.

Yup. M50, S50, M52, S52 all use the 400 casting.

Yup, add a tune and you will be close to stock m3 power.

Do a war chip. most reliable option, and it will give you at least 25hp.

[NbAmTwE]

who thought 20+hp. It's like 2hp maybe or maybe minus 2hp without a tune.

M52 and S52 heads and valves are the same. The only thing different is the cams. I have a set of S52 cam I would be willing to part with for $350 shipped. Let me know.
