guys, anyone tried the N42B20 intake cam swap?
the specs look good, but physical instalment  did anyone try it?
i may get hold of one in a couple of days to check.

cheers

No sorry most of us have m42 heads, which pretty much stuffs any chance of using the later engines camshafts.

update, the N42 cams won't fit, so i'm settled on high compression ratio 11:1, port and polish of intake manifold, enlarge the high end runners and double the air box capacity for the high end runners, enlarge the second throttle to 57mm (i found a shop)...

the other alternative is to install an eaton supercharger from a mercedes on the stock compression ration and internals, but i'm still studying this option, as the main issue I'm facing now is remote tuning as the build will be custom....

i've been porting out and polishing my intake manifold, the amount of material to be removed was really significant, also i found out that the ports of the M42 are much more symmetrical unlike the ports to the head of the M44 that got 1 and 4 a bit chocked down....
will port match the three parts of the manifold together very soon, as they are not aligned together.....
really the casting quality of the manifolds is not that good, a lot of work to be done, but i enjoy it :)

very interesting info on Cat cams, the exhaust cam has more duration than the intake cam, but with the same lift!

STD249°/257° - 207°/209° - 9.70mm/9.70mm - 1.20mm/0.55mm

that's exactly what they have on their website... any idea if i can swap them?

one last thing, when you guys state your cam profiles, which digits you usually use? the duration@0.1 or the duration @1.0?

That's quite surprising since m42 standard are 240 deg 9.7 mm. Don't think anyone has longer duration cams on there exhaust.

It's generally longer duration on there intake cams.

I was shocked myself, but their data are supposed to be accurate

I just checked on their website now, they state this for the m42:
STD255°/255° - 207°/207° - 9.70mm/9.70mm - 0.90mm/0.65mm
