just wondering, it might be stupid, but would a vtec controller work on a y5, cause its.....vtec-e???

 

can anybody answer these please....

 

Could you?... Prob but I dunno
Should you?... no
Will it help anything?.... no

 

yeah i'm thinking about putting a vtec controller on my car as soon as i put some more money into my D16Y5

 

about the only thing you're going to accomplish on a d16y5 (or a d15z1 for that matter) is wiring the vtec solenoid to a constant 12v, so that the engine now functions like a normal 16v sohc engine.

or, if you're a ricer, you can move the VTEC point up a couple thousand rpm so you can hear mad VTEC y0, but all you're really doing is choking the engine engine more so.

thanks for the input, and would hooking it up to a constant 12v really make it run 16 all the time...and if so, i would gain some low end torque? and also...i dont understand, moving the vtec point up...that would be done with a vtec controller, correct? sorry for being such a noob, thanks for all your help though.

Can you expain this to me....

 

Why put money into a y5 when you can get a y8 witch will get better power gains.

 

the y5 only runs off 8 valves until the vtec-e kicks in and activates the other 8 valves. Also, rigging the vtec solenoid to constantly keep the car in "vtec" mode will fry the solenoid, so don't try it.

I understand that...I want to know what wiring it to a constant 12v will do

If you have nothing to contribute to the HX, why post. No one cares what swap you think they should do. Some of us like to keep the stock motors we have and I have had LOADS of fun with a turbo Y5

Fry the vtec solenoid. They operate off a ground.

why get a y8 and put money into that when he could get a B18/K20/etc which will get better gains

why put money into a low displacement 4 banger when you could get a big V8 which will get better power gains?

It all personal preference, now maybe the a y8 swap or head swap would be a good option but if he wants to mod his y5 then let him.

As far as the Vtec controller though, he can if he wants but money would be well spent elsewhere IMO.

So am I missing something. The other guy is saying it will make it run like normal VTEC which I thought sounded stupid but if someoen can make sense of it for me then , but if it is going to fry the solenoid....how will it operate like normal VTEC...LOL

 

it wouldn't operate like a normal vtec. It would operate like a normal 16 valve engine. Pretty much just like a d16a6 or something. So basically it's pointless.

Well to get back to teh original questions

It IS pointless to get a VTEC controller on a Y5 if the only reason is changing the crossover and your car is stock or lightly modded and there will be no dyno tuning ( why would dyno tune light mods). If you MUST change it, at least get a P28 so you can have other uses besides just changing the vtec

 

thanks for all the input, what turbo set up are you running spec? what did it cost you?

First time I ran a greddy kit with the AFC hack. Cost me around 1400 or so.

Second time I built a custom kit and ran uberdata. I pieced everything together for aorund 1300 and that included a tuning laptop and a chip burner

 

im thinking 14b or 16g for turbo set up, anybody have any suggestions?

FYI there have been some dyno charts floating around here a few years ago where a D16Y5 with the same mods as a D16Y8 laid down MORE power than the D16Y8.

What sucks *** on the HX is the horrible transmission - the gearing is so long for mpg.

First mod for any HX with spped in mind should be a Y8 tranny - hands down the best bang for the buck mod.

You could boost that Y5 into oblivion and still be ****-*** slow due to the terribly long tranny gearing.

Oh and the original question?

I'm not 100% sure, but I'd be willing to bet that you'd throw an array of check engine codes after you hook up a V-AFC to a D16Y5 because they are OBD2, and also the most emissions/fuel mileage sensitive ECUs in any 96-up Civic.

even if you could keep it in vtec all the time, it doesn't make any sense to. it'll just kill your low end power and torque. you would be slower than ever. there is no reason to touch your vtec engagement point unless you have aftermarket motor internals, and you are tuning it on the dyno. Then you might see some improvement by moving the crossover.

I just wanted to quote this so people read it. This man speeks the truth. I dont know why it is so popular to want to "change the vtec engagment".....

i have y8 5 spd. so would boosting it be a good bet?

 

also, do you guys know of anybody who will build a kit for cheap???

I can atest to this. For ***** and giggles I set my crossover to 1900 rpm because I was reading people say they want to be in vtec all the timne and my car felt like crap. stock crossover owns me

wrong, it runs 12 valves in lean-burn mode. 8 exhaust valves are always opened and 4 intake in lean mode and 8 intake in vtec

EDIT i am seeing more and more d16y5 posts. This is interesting, maybe because of my project i'm stirring up hope in the old vtec-e motor.

if you want your hx to be faster, get a z6/y8 tranny
then boost
