1995 M3 S52 track drift car build
-
ok so i tore the block down and i was looking at everything it looks pretty good, i have several questions
1 are mahle pistons stock for the s52?
2 what do you guys recommend for piston rings for boosting it
3 should i get new lowered bearings? (they have minimal scuffs that can see but can't feel. i feel like i should spend the dough to get the super good ones.
4 is getting the crank micro polished and lightened worth the money,
5 should i upgrade the valve train, (valves, springs, retainers) and also would it be smart to convert to solid lifters?

There is no such thing as "super good ones", coated ones are a waste of money and have no benefit, come to think of it I have only heard negatives lol.
If you wanted to you could replace them with oem ones.
A piston ring is pretty much a piston ring, there are no rings made for boost or NA
I wouldn't mess with the crank, they have harmonic issues at high rpms as is, can't imagine lightening it would be better.
Solid lifters cost a lot and require grinding of shim caps to set lash.
How high do you want it to rev? High RPM's is where it's harmonic issues will really start to shine, and you will need to purchase an aftermarket vibration damper (~$850)
Food for thought.

Wonder if it is Andys old car
How many black E36 M3's has he had?

anyone know someone selling s52 cams and trays???? the guy i bought the car said he was going to get me some but thats if he remembers and when oh god i don't want to know so plzzzz it'd be a huge help
I'm not sure if I missed something but what happened to the original cams?
-
That wouldn't be good. One thing that is on my list of ideas is making something similar to the factory tool that pushed down on the cam and tray evenly so you don't have to sit there for 2 hours trying to slowly tighten the damn things down.

I did my intake cam without any trouble without special tools. I turned it so only cylinder one had pressure on the valves and with someone holding the square with a crescent wrench so it wouldn't turn suddenly removed all of the other caps. Then I released cylinder one a quarter turn at a time. I don't know how close to the line I was though? I removed my m50 intake cam and installed an m54b30 cam in it's place.
-
so i picked up some 328 cams for cheap with a whole motor that ate a couple valves to put in the m3 to get it running because m3 cams are just ridiculously expensive and the duration is slightly longer with the 328 cams with a slightly shorter lift but i think i'll live with it once i get my tax return back, I'm ordering piston rings, new bearings, get the block hot tanked, and honed, and possibly port and polish the head. and probably coil overs on the suspension side of the project
-
Ik it will probably hurt power but I'm just going with it for now to get the motor together with the turbo and completely rebuilt. from what i've heard from some people is that the cams may help with the turbo setup with the slightly longer duration. but this is my first go round i want to get it together, and see how i like it and go from there

Don't waste your time or money on the m52 cams
-
meh not so much a pipe dream just saving up to buy what i need, i have a lead on a full AA turbo kit and am waiting on a response so thats where i stand right now, i've decided to stick with stock internals for this year and keep the power when done around 500 i think that'll be enough to mess with. I've been so busy with work its been hard to give the car any time but once i get the parts i'll make time for it
the body looks clean from the pics.
