Kool. Don't know much about cams on the Z... hope to learn a lot from this thread and possibly attempt to make this mod if it benefits me? I know the benefits are mainly with torque which we desperately need. But I'm wondering if there are any drawbacks

I wish they had tuned power comparisons on a stock Z instead of one with 12.3:1 pistons

Apparently they used different (bigger?) fuel injectors too.

Hmmm.

I think vendors especially GTM should do the independent install and dyno to increase the market of this thing

Cams installation is not that difficult as cams are the top part of the engine so accessing it is pretty straight forward. But fast cam mod is definitely something not to be DIY, best get a good mech to install it as cams install requires clocking tools. As the cam durations are different from oem cams, your exhaust note, idling will all be affected and a tune would most likely be required although you may get away without a tune but you will suffer erractic idling and even occasional stalling when you clutch in. Something to think about for those keen to install.
