Has anyone used or heard anything about these? They sure look nice! http://www.cranecams.com/import/hvteccomps.htm

 

I can't help but notice that they say you can't use these with stock cams, I was wondering if they are alright to use with Skunk2 stage2's?

 

Most aftermarket companies dont have the technology to build a vtec setup.. I wouldnt trust them to try and mirror hondas design..

 

how are they trying to "mirror" hondas design with a roller setup?

ive herd of a people using the skunk2 stage 3s with these..dont know if i would try it but i know they have done it..maybe they grided down the 1st and secondary lobes?..or maybe they didnt have to? ..oh well i would just use the roller cams i guess ?

They are using completly different rocker arms which is where most of the vtec system is.. As far as the vtec pins locking and unlocking the rockers..

there isnt supposed to be locking pins for vtec the rollers are made to eliminate vtec (basically vtec engaged all the time) thats why u use "vtec killer" roller cams with these....and there mirroring hondas design how?

Ahhh.. Didnt know that is eliminated the vtec setup all together.. I thought this was a roller rocker vtec setup that they were selling.. My mistake..

 

thats what i started to realize...it would be nice if someone did make one though..u think? or do they?

I've never seen one out there if they do.. Would cut down on alot of drag in the valvetrain though..

 

So i guess these things just convert your b-series dohc vtec head into a high flowing ZC head then..

 

well dont the zc and ls have those "ball joint" type rockers?..i would imagine they arent as safe or stable at 9000 rpm and up then the "shaft" vtec rockers..oh well maybe im wrong?

 

Not sure what you mean by ball-joint.. I was refering to the fact that they turn you b series head into a dohc non-vtec like the ZC head but flows alot better then the ZC head.. I wonder how crappy the idle would be with this setup..

 

sorry i wasnt more clear...what i ment is u see how the rockers in a ls or zc head basically are secure by the rocker just sitting on a ball joint and the cam lobe as to the vtec rockers are secure with a shaft.

its very lopey!

 

I have to wonder why my H22A doesn't have roller rockers. My F22B1 has roller rockers...

 

There are a few other post on this board asking the same question and nobody seems to know anything of them. Too expensive of an upgrade I guess.

From what I understand they kinda work off the same principal as todas vtec killer camshaft kit. EXCEPT the cranes ride on the vtec lobe while to todas ride on the primaries.

If you looking to lose weight. Spoon made/makes a lightweight follower kit for the b-series. But like most spoon parts they are pretty much warmed over stock pieces that are a little lighter, maby stonger and cost mucho $,$$$.$$.
