I took a 1991 build e36 m50 non vanos cylinder head
added:
S52b32 vanos business with complete cam trays and cams from S52b32
to create a chimera of:
dual valvesprings + 7mm valve stems
+
s52 cam setup
+vanos
for reference:

notice a similarity between the front cover plate and an identical gasket shared between them?

The only way you can add s52 cams to that motor is o get a m50 vanos head. m52 might work but non the less you need a vanos head.

You can do what ever. Heads have the same casting.
If you are running s52 cams you just need to have s52 trays and lifters.
Motor I am building is using a NV block with NV head and S50 cams w/ Vanos unit.
M50 3.1L Stroker - TC Kline D/A
I think the head casting is the same. You would need to transfer the lifters, cam trays with the cams. not sure about the valve clearance with those lifters and cams.
try to get new valve guides.

Head @ machine shop. Will have it next week or so-
Are there any speciication difference between the nonvanos and vanos lifters?

Answer to your first question, yes. I actually just came across someones build, just like your, not too long ago on here. They even had the VANOS unit tucked into the non-VANOS cam gear cover and valve cover. So when it was all buttoned up and going you still didn't know it had VANOS inside it. Don't recall the link to the build though. If I find it I'll get a link for you.

This dosnt make sense- The vanos unit cannot fit in the nonvanos cam cover, You have to clearance the NV cylinder head casting a slight bit to clear the vanos assembly as it takes up more volume than the non-vanos fron head plate cover. Vanos head castings have more clearance there, it pretty much just profiles the front plate gasket where the NV head has more meat on the intake cam area side (simply didn't need the clearance).
What you saw possibly was a vanos motor with vanos deleted, nonvanos cams and carriers and sproketry in place with nonvanos valvecover, etc.

Nonvanos head bolted on s52 block with camtray, lifters, cams and vanos from s52 installed; plug and play. DME fired it up just like a S52 normal, no real big difference.

I did it all I had to do is switch the front intake cam cap and shave some metal off the front of the head. No rocket science. My dillema if anyone can help is the valve size and compatibility issues. If I have a non- vanos head wil +1mm vanos valves replace the ones in the non vanos, with a little machinist persuasion...
Im also running 95///l/l3 schricks

vanos valves have 6mm stems. non vanos is thicker at 7mm. The valveguides are the only thing that determines this, so if you are changing stem diameter - swap valveguides to match.
the 6mm valves have less mass and technically a tiny bit more flow, but they are also known to drop heads.

Any updates?
I recently got a cracked S50 head and will be doing the same thing:
-Convert to 413 with M3 harness, tooth wheel, all the sensors including cam sync, MAF
-Install vanos, cams, trays, lifters
So the end result: S50 head with dual valvesprings!
Anyone know if compression changes? What about valve relief with the duration changes from Vanos?

basically using a M50NV as base for build up:
you would + s52/m54 crankshaft or S52 shortblock for 3000cc or 3200cc
add s50/s52 cams / cam carriers+ lifters+ headers+ vanos+valvecover (or s50/m50vanos valve cover so you can keep the 4 bolt coil packs.
the head has slight difference in bowl shape, my machine shop examined them side to side after pressure testing my old s52 head and doing a valve job and seal replacement on my M50NV head, they said it wouldn't be much of difference, decking the head would do more impact.
402 ecu cannot run vanos.
but you could run double M50nv intake cams to have hotter cam setup and keep the non vanos setup, unless you really feel your application needs the vanos-
between s50/52 and m50nv all Valves are same diameter, only valve stems are different diameter.
you would do same as I did with my S52

Whatever happened with this thread? What are you revving your s52 w/ NV valve springs to 7500RPM?
I installed s52 vanos and s52 trays+ cams into the non vanos head; I drove the car a month- rev limit stayed the same as I was using stock s52 cams and dme.
Then I removed the s52 and installed a complete s54b32 engine from e46 m3. That one rev'ed to 8400rpm and was more worth the effort
Nowadays the cool thing to do is install dual vanos setup from m54b30 into s52 longmotor so one can spool up a larger turbo with dual vanos. The iron block is also stronger and takes heat stress better than the aluminum m54 block; 200cc additional displacement is also nice

Doing a m50nv with s50 cams and adding a m52 vanos (1996 328i) with an 413 dme and e36 harness. Afterr much reading should be a straight bolt on. I'm not taking the head offf and therefore valves of 7mm will stay. My question is in regards of a chip to tune it. Which chip will be best on a small budget for a DD sleeper? I heard the TMS chip but would like more input.
finalyy this will need to be BAR as a 1992 engine
