carbed vtec?????

[85lude]

ok i plan to do a b16 swap in my 85 base prelude i have my dual dcoe carbs and the manifold for the b16. there were some guyes at prelude power that told me to come over here and ask to see how you juys got the vtec to work with a stand alone system. so im asking how do you get vtec to work???????

[89AcCOrDmike]

this is way out of my league but i'm not sure if we have ever had a carbed vtec on our sight...everyone i know has switched to fuel injection before a b16 swap

hey, i have seen a carbed VTEC engine. it had the dual weber dcoe's on it. i couldnt figure out why they would do it, but it was cool and fast just the same. well, this is the closest thing to a carbed VTEC. its a carbed GS-R integra motor in a civic hb.

Individual throttle bodies... not a carb on that b series picture.

vtec soleinod gets switched by ECU, so i don't know how would you switch it with carb setup.
your best bet would be to do NON-Vtec motor and build it up with high compression pistons and so on and on.

Try one of those rpm based swithches frm MSd and such. Don't really know about this sibjuect just throwing out an idea.

[POS carb]

yea basically you need a module that will send a signal after a preset RPM, a standalone ignition can probably be used to trigger it, hell you can probably do it with a tach shift light

With a vtec engine, an rpm based module should do the trick. If you jet the carb right, you could stand to make some hellacious HP.

those are carburators, or thats what they said. they are weber DCOE's. not individual throtal bodies. and considering i can see the braided fuel lines going into the fuel inlet on the carb pictured, i dont know where the fuel injecotrs are. if you can tell me, then ok. but those are DCOE's. dont believe me, look.

An external vtec controler is very easy to find. Be forewarned, its going to be a pain in the ass to get the carbs tuned right on vtec. There is something about changing cam profiles halfway through the rpm band that a devcice that meters fuel based on serveral small holes and the vacuume pressure of the air passing though it does't like.

so if i get a aftermaket tach and a vtec controler then i could hook the vtec controler to the solinoid to trigger it right??? because the vtec controler controls when vtec hits right??? so why not that way???

[2old_honda]

just like phydeaux said, you might be better off going without vtec. just get a more agressive cam.

[85lude]

no i want vtec i dont think it will be that hard to tune the carbs and to hook up vtec i'll just have to look it up some more if a gsr can run carbs and have vtec and run as good as having efi i think i can do it with a b16.

This pic still could be EFi

Weber makes a DCOE Throttle body with injectors.

I never said it coudln't be done, I just said it wasn't easy. I read a few pages on running one on a b16 trying to dig up a manifold for one to mod to fit my a20 a while ago. Thats the most I looked into it. Some have done it, I believe the easiest way is to have the vtec kick on as low as possible. If I were in your shoes I would have just gone with a b18a and cammed the hell out of it. But thats just me, I prefer things cheaper and easier.

Those are carbs in that pic. Look at the way the fuel lines hook up. Yes weber does make throttle bodies, and there are plenty of places that also make dcoe replacement throttle bodies, but those are carbs.
