Schrick cams are the tits, but, they will cost you more than the car is worth :)

One mod is to swap intake cam to exhaust cam and buy "wilder" intake cam..

does that mean that two intake cams would be an improvement?

doesn't the s50 b30 provide upgraded cams for the m50?

Can anyone suggest how to test if the boot lights are staying on with the boot shut?

Yes, what i mean is that intake-cam profile is "wilder" than exhaust cams, so swapping it to exhaust cam and bying "wilder" cam to intake cam livens up your engine.

I'm not sure if S50 cams are straight bolt-on to M50, but definitely they're improvement.

So, yes two intake cams in one engine would be better!!!

No, it's not improvement to put two intake-cams on the engine. When you swap intake cam to exhaust cam you need to bolt "wilder" intake cam than the original, otherwise it won't work well.

Waste of time messing with inlet cams, and this can only be done on a Non Vanos engine. You are better off advancing the inlet but it will affect the idle and make it sound like a tractor. Unless you have a pair of performance cams there is no point changing them

Or if you have S52 cams sitting there that cost you nothing or very little.
