anyway i asked one of my friends to make sure about it and it's HP Gain
when i have any news, i will update here :iagree:

Subd

Interested..

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 know the labor will be a real nightmare

Hahaha... yeah kiss the warranty goodbye with this mod. Lol

Useful without being able to tune VVEL???

Interesting...

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

willing to take a chance on these, but need to know the following, what kind of labor is involved? what is needed to be done to fix those, how many hours of labor are we to expect with and experianced mechanic? And will the car need to be tuned when these are installed? if so will uprev do, please someone chime in, btw where can i order them from?

and one more thing, how difficult is this job on a scale of 10

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

Hmmm.

well ... i can't tell but believe me it needs a professional mechanic to install them perfectly
don't try install them by yourself :gtfo2:

and if you want to order them, i have a japanese friend in facebook and he is doing a good business by exporting Parts from Japan
i can give you his account if you are interested

Hmmmm .... I have an idea
you can install them and do the comparison :tup:

anyway i want to know how much HP i will gain if i install them on stock engine
maybe we have to wait till someone install them :icon17:

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.
