I’ve been doing some research on m50nv cam upgrades. I read that people put an intake cam on the exhaust side which gives you a 240/240 setup. Would this be noticeable in a N/A application? Is it even worth it? ---

it’s all about the budget ballin’ and M50 cams are cheap and I don’t think you need to re-map the software. ---

Aren’t S50 cams VANOS? M50 cams are dirt cheap, Figured I could pick up an intake cam. All I can find is people doing this swap for boost applications, Which I can’t afford right not haha ---

> [@theblue](#): > > no, S52 are vanos. I thought S50 were single vanos? > The S50B30US was a 3.0 L version, which powered the US-spec E36 M3. Power was 240 hp (179 kW). Unlike the RoW S50, this engine used a regular M50 intake in lieu of the individual throttle body set up and hydraulic valve lifters in lieu of solid ones. The cylinder head and the VANOS system are also different on the US S50 versus the RoW model; again having more in common with the regular M50 than the Euro S50. ---

I’m confused now… looks like the 1995 did have single vanos, but it’s not on the chart on wiki: > **[VANOS](https://en.wikipedia.org/wiki/VANOS)** > > VANOS is a variable valve timing system used by BMW on various automotive petrol engines since 1992. The name is an abbreviation of the German words for variable camshaft timing: variable nockenwellensteuerung. The initial version (retrospectively renamed "single VANOS") was solely used on the intake camshaft, while the later "double VANOS" systems are used on intake and exhaust camshafts. Since 2001, VANOS is often used in conjunction with the valvetronic variable valve lift system. ---

Euro s50s came with double vanos. m52s got double vanos somewhere around 1998/99. All m50/m52 based motors between 93-98 were single vanos. ---
