My swap M50NV+S50 cams+M52 vanos......

[amcink]

M20 is out; another step closer to the M50

And the surgery begins!!! Should be ready in 2 weeks (due to my work schedule)

Awesome build! I just used dual intake cams on my NV to wake it up some

This is an interesting old school take on it -some overlooked issues

Hard to time properly.

No knock sensors.



The most drastic change between the NV and vanos is Knock sensors. This allows computer advance of spark till knock threshold- its an upgrade in processing power also

on the cam shaft sensor, which oring you used?

Emmanuel
I used the non vanos oring. I took it off the non vanos cam sensor and install it on the vanos sensor. It fits good only when i screwed back the sensor be careful since it fits tight once the bolt is all in.
Attached is a photo to compate the oring sizes NV small Vanos green ( too thick)

I was evaluating such solution. However i decided to go S50 cams and vanos to take advantage of the lower end torque for daily drive plus I'm getting a TRM chip off the shelf for $350 which only will work with a vanos engine and S50 cam set up. So if everything goes well I'm expecting a 205 hp engine approximately; until i do a dyno. More to come!

yes NV and Vanos are about 120degree off on the timing

you def need the vanos damper

Is there a part number i could refer to? I will cross check it at realoem.com
Ok i checked realoem.com and the non vanos damper has a number of 11231730311 and the vanos damoer is a different number 11231738620. Is this what you are refering that i need a Vanos vibration damper since the teeth space is in a different location? Then i need to go to pick n pull to get it. Valve cover and wire harness already have, the valve cover is the one on the engine already

[RobertK]

Forgot to mention this until another member brought up the question but be aware that you will also need the VANOS crank dampener (the space in the teeth is in a different location), wire harness, and of course valve cover.

Good thread. Nice to have something to refer people to when they ask.
