All vtec killer cars ive seen go full billet engine mounts/super stiff suspension/open exhaust/2000cc or bigger horrible idle injectors/aggresive clutch/70mm plus sized throttle body and huge intake manifolds and that really makes the car unstreetable. But ive yet to see a dyno graph of a vtec killer set up to get an idea of how much they affect everyday street driveability.

I'm waiting on my cylinder head but i'll post up video comparing idle to 5k runs with vtec on vs off when i get my car back on the ground. It's a matter of how much noticable power is lost and if its worth the sound and how the lumpy idle 'shakes' the car vs the hp loss. I have a twinscroll setup so i think it'll help even out some of that lumpiness, might even help kick that turbine and spool it up abit quicker idk

we have high and low cam lobes a.k.a. vtec. Ive been trying to figure out if any company keeps oem low cam lobes oem and makes high cam lobes more aggressive only giving us the best of both worlds.
