Hey, anybody does bigger cams for vvt engine? There are few different brands with many durations available and its almost impossible to find some builds and impressions of bigger cams in vvt, i Just Will find some info before i decide to does mine, i Will reach power spike in 5k to redline and maybe spin engine Little bit higher, i have many other mods already like honda intake with throttle body, adjustable exhaust Gear, depower steering, electric water pump, light weight flywheel, free Flow exhaust and of course standalone, all mods for fast revving and agressive response engine, i think about cams With stiffer Springs can do alot with this build but im curious why i can't find anybody who does bigger cams in vvt

 

Maruha does, at least i thought.
by what i understand, aggressive springs and cams lead to the VVT system being hard to control if even usable.

 

Maruha does, kelford, catcams, many other also does, i have camshaft workshop in my country with big expirience, they can regrind mine or do custom ones, for example i thought to do set of 268/260 with +1mm lift, and vvt have 44 degres advance, they can do for me intake where zero Point Will be at 22 degre which Will give me another 22 degre of advance and 22 degre retard, and with it i Will be able to tune Best power band in whole rpm range, but maybe there are some cons which i dont understand yet

 

Biggest "problem" is to mechanically reduce the sweep of the VVT to prevent piston/valve contact when you loose perfect control of the advance.

I have not heard of anyone doing cast blanks in a long time, but I have not been hunting that actively since I got mine (second last one from Mazda back in 2012 IIRC). Custom in steel is always an option.
