b16 eliminate vtec???
so this may be a dumb idea... but lately iv have been liking the idea of ls non vtec turbo.. but due to the ls head design vs b16 what if you use the b16 head(for flow and rocker arm design) delete vtec rocker,solinoid etc and run a cam from web or crower????

Re: b16 eliminate vtec???
Doesn't work like that. I guess you may be able to make a spacer to keep the primary rockers seperate... but why waste your time? The only real option is something completely custom like a VTEC eliminator kit. Really your goal is nothing new, the route you are trying to take is unconventional...

lol.... versus an ls head for turbo.. same cam profiles or even alil more agressive. the b16 head flows better and has a better rocker arm design. again for lsturbo guys. not everyone wants vtec.

Re: b16 eliminate vtec???
Why would you do this? Even with a turbo you will loose a lot of top end power by removing Vtec especially if you run a cam profile similar or "a little more aggressive" to a LS cam. Vtec Killer kits are normally used on high HP race cars and most are drag cars and top end high rpm power is the goal. IF you want to go non Vtec for whatever reason then get a B18B. The Ls heads are not really known for throwing rockers So I would not worry about that too much. I just would not rev it past 8K and that is with stiffer valve springs.

Op, check out the prices you should expect
http://www.team4piston.com/camshaftsB.html
Bare minimum, $1,800. You'll still need valve train......

Re: b16 eliminate vtec???
I would also like to know, I'm going to be using a ecu that doesn't support vtec for a lsvtec setup using type R cams and was wondering how much is not running vtec is going to hurt the setup? Is there any other way of controlling vtec without the factory ecu?

Re: b16 eliminate vtec???
actualy its the same concept.. an aggresive non vtec cam.. the webcam comes with rockers to support the cam profile. seems like the only way to go bigger than what a ls head can do. my original thought of having an ls cam profile was def not a good one..

Re: b16 eliminate vtec???
As I already stated, unless you eliminate the VTEC rocker, you will destroy your valvetrain/head in short time revving it much past 6.5k RPM... It is either a VTEC eliminator kit or nothing...

Re: b16 eliminate vtec???
Im kinda curious if this is going to be an all out race car or power levels desired? I dont see the point to go through all the headaches my self as Vtec has been proven to work well in any application it isnt like it would be hindering.

Re: b16 eliminate vtec???
yes your right about that.. my original thought was of vtec killer but on a smaller scale for the cam profiles...... and it would be a waste of money to do all this work to a vtec head. my original thought was about doing ls turbo and than started thinking that utilizing a vtec head with out vtec would be another option or modification to a non vtec turbo build..
so why would anyone do this????? what about the ls/b20 turbo guys?? why wouldnt they use a vtec head??
i like the idea personaly.
as far valve train... how would running a cam of similar lift duration to an ls/b20 or anything that the ls/b20 turbo guys run, in a b16 head destroy the valve train but not in ther heads??

Re: b16 eliminate vtec???
current is 198hp b16 that i built.. previous to that was 440hp e85 turbo b16(on stock cams). wich is what im wanting to do this to... end result being a nonvtec turbo..
I like the idea of nonvtec turbo.. thats simply personal.. since i already have the whole turbo engine- golden eagle sleeved block, arias pistons, eagle rods, etc i was wanting to eliminate vtec, and use a mild cam profile.

Re: b16 eliminate vtec???
You obviously don't know anything about VTEC heads. I have already stated why the head would get the living crap beat out of it. The center rocker isn't designed for for free floating high RPM use. I see this discussion is going nowhere... Why not just disable VTEC and rack it out to 9k RPM everyday and find out what happens for yourself then? Have fun.

Re: b16 eliminate vtec???
obviusly i do since i stated to delete the vtec ROCKER.... same concept as the webcam kit.. but with a reasonable cam profile.. the reason the webcam comes with its own rockers is to accomadate the rocker pad for the large swipe of the lobe.
so regrind a stock cams nonvtec lobs, remove center rocker and lma spring (insert spacer), retaining stock rockers
other than a regrind cam ther isnt much money spent.
no trolling here. just wasnt sure if i was overlooking something or just general ideas to using this head

Re: b16 eliminate vtec???
If you're going the route of using the OEM outer rockers, here's an off the shelf solution, though profiles are probably far from optimal for your intended use.

You're gonna need custom grinds to make this worth while, which even then I just don't see the point.
Also gonna need this stuff as well.

Re: b16 eliminate vtec???
This is stupid as fk... Sure there's frank builds but to mess with the original design of a b16 and make it non VTEC that's just a waste of time. My curve the cross over is so smooth you'd need glasses to see the line dip and pulls all the way and beyond 8k . Why change that

Re: b16 eliminate vtec???
awsome find!!! thats what i was imagining... being toda it may be pricy but also worth it.
i understand the original concept for that was aimed at a specific racing class that didnt allow 2 cam profiles.
and i understand that running a large cam profile ALLLLL the time isnt good for the long term.. thus the rout of a regrind mild cam profile.
