New Billet camshaft for 156/159 video by Tasos
There are billett cams for other engines and it wears the buckets hard.
Cams need to be coated with some slippery coating.




In the M156 the issue isn’t just the cams it’s a combination of the lifters, cam adjusters, AND cams. So do all and like it’s been mentioned if you open the head up you need to replace gaskets and the adjacent parts like bolts and whatnot. Some bolts are TTY! I will agree to do it properly it would cost 10k at minimum. That also depends on how much the gulf-performance cams cost if you go that route.
if you work on it yourself you’ll need the special timing tools and knock on wood you don’t screw that up and end up with a larger bill.

so if you think there is going to be a cheap route of increasing your hp on a M156 it's never going to happen. Yes you might have a supercharger, longtube headers and throtle bodies to get 600 - 650 the difference is that none of the other motors will never have the M156 sound

But billetcams are made from non 'selflubricating' steele. and thereby wear the buckets harder, or if unlucky it wears the cams faster.
Seen it often in other engines.
billetcams are good in the m113 engine thou, due to roller rockers.

The low friction properties would reduce wear on both surfaces, even the uncoated one, because friction will be significantly reduced. I definitely would at least go for the SLS Black Series buckets if I were to drop the coin on these camshafts.

I like how hes fully documenting everything with the car, as in maintenance and all specs etc. Hes not just trying to sell cams. Hes trying to show what these cams will do given all other variables the same. Which is the way it should be.
He could of just put the car on the dyno with bad adjusters and worn cams and been done with it but chose to fix it first.
