Yeah, it seems like old school cars, and hondas are nearly the only markets who buy cams in "stages"
I know that with toyota parts, especially for the 4AGE they are always refered to by lift.

i do believe most high end competition honda engines remove the vtec system, especially in the sports compact racing series, drag or track
Not suprisingly, Commodores do everything in Stages.. Haha
Stage 2 Head Package! Stage 1 Gearbox Upgrades! Stage 3 Turbo Package.. God damn they're useless lol
Mugen_ctr i'm fairly sure that's correct, but they don't remove it.. They lock the VTEC permanently on, because the changeover when hitting Vtec would do serious damage to your engine with a really serious Cam!
whats the point of that? you might as well have a SR20 or 4age20v with the same lift and duration cams as what a competition B series would have?
Go look up vtec killer cams.
Sent from my Xoom
i know 'bout them. i just dont see the point of getting a VTEC motor to swap out a great design. to then swap in an less efficient design
low cam is just for drivability/ fuel consumption/ emissions
how exactly do you lock VTEC on? Technically, if the cam profiles don't change, it isn't VTEC. It's no longer variable valve timing.Quote:

You take away the ability to run 2 cam profiles (economy/perfomance) and are stuck with just the one profile (performance).
In theory, you could they remove *ALL* of the VTEC hardware, sensors and circutry because you basically just running a simple DOHC motor.
that what i meant. The concept of locking vtec is absurd.Quote:

(just had to ask)
Same story. SOHC VTEC still have two profiles (economy Vs performance). Install a VTEC KILLER cam and you've basically swapped out the 2 profile cam for a cam with only one profile ---> performance. No longer need a VTEC system to switch to another profile (cause there isn't another one), so you just plug up & disconnect VTEC.
