I just installed a JDM d15b vtec engine in my VX hatch and I can't tell if the vtec switches on or not...can you all tell when yours does?

 

When i'm trying to feel it I feel it. When im occupied with staying on the road I dont feel it.

 

I always feel mine.

 

I sort of feel mine, can hear mine, and can definitely see mine (VTEC light). I actually thought mine wasn't working at one point, so that's why I hooked up the VTEC light. It's just this little miniscule LED drilled into my dashboard, most don't even know it's there until it turns on.

 

assuming you have a JDM ecu, I think the JDM ecu's have a much more tuned vtak xover so you wont feel it as much, you will just HEAR it when it switches lobes. dont quote me on that though.

 

How do you rig that up?

Here are the Radio Shack parts I used:

330-ohm resistors: #271-1113
5 mm blue LED (or any color you want): #276-311
18-gauge wire
LED mount: #276-079
Tap-ins: #64-3053

I then just used a tap-in to hook into the VTEC solenoid wire in the engine bay and routed the 18-gauge wire through the big grommet on the driver's side. Solder it up to the long LED lead and then solder in another wire to the short lead, which I connected to a pre-existing ground wire. After that, figure out where you want to put it, drill a 1/4" hole for the LED mount, stick in the LED, clean everything up, and it's done. Very simple.

 

D16Y8, CAI, DC header, Apex WS, I couldn't tell you where the cross-over is, but when the spray rolls in, you sure can tell that something out-of-the-ordinary is going on

Where do you put the resistors? Is there only one wire for the vtec or are there 2? If 2, which one(color)? By the way, I'm on my way Radio Shack right now! This is a great idea.

 

What kind of motors do you guys have where you can't really feel VTEC?

Oh, sorry. The resistor goes inline with the ground wire. I just soldered one end to the short lead on the LED and then the other end to the 18-guage wire. And at the solenoid there will only be one wire, which is green with a yellow stripe. You'll have to cut back some of the black covering that protects it, though. And if you can't figure out how the tap-in works, use a few to practice on some extra wire or something ... don't want to **** up the solenoid wire. It's really simple once you see how everything should go.

EDIT----If the LED is too bright for your eyes, you can swap out the resistor for a higher rated one, like 400 ohms or something.

D series.

i never felt vtec on a single cam, only on a dual.

 

my ls/vtec feels like an explosion when vtec hits

same here... the old Z6 i had only made a little bit more noise around 5,500 RPM's. couldn't feel anything though...

now the B18C, i can feel it around 4400 RPM's and hear it... then at 5,600 RPM's you can defintely hear it, but not feel it as much.

 

it is not impotent 2 feel it !!! cause that = bad tuned cross over point !!!
you can make any vtec engine, so you can feel it !! just a mater off losing power on the small cam and then let vtec kick in makin alot more power !!

but my D16Z6 you can HEAR it !!!! and if you kill vtec on this engine you are losing some 20 HP !!!

JDM D15b vtec

:werd: i've never felt vtec in a sohc (xcept type-s V6). but i can feel it on my stock b16

 

I can feel it in my G/F's EX. Revs a lot faster when it kicks in, big sound difference too.

 

i dont feel or hear anything on the changeover with my sohc vtec... no matter what i set it at.

although, on my friend's s2000 i notice the vtec roars and hauls ***.

 

I can not feel vtec in my stock 92 vx. It is vtec-e.

 

haha

VTEC on the SOHC is very week, unless you have alot of mods and upgraded cams and what not

Have u ever been in a B16A2 with Skunk2 parts all over the motor(Cam Gears,Cam Shafts, Valves and Springs with a 9,500k Redline, holy ****, my boys VTEC is louder then my BOV.

 

on my 99 ex, i can't really feel it but i definitely can hear it switch over...

 

when i had my old car
with the d16z6 you couldnt feel ****
but with the jdm b18c prolly like a 10ft-lb kick
you could definatly feel it especailly at 5th cruising like 80-85 at like 87 it would kick over and the little blue light owuld come on (vtec light) and it would change pitches and give you enought uumph to know you were on the hot came. damn that was cool

but now it happens like 2000 rpm earlier and the uumph is like OH ****!!!! (b18b turbo )

 

When my S2000 gets past 6000RPM, it's suddenly an F1 car... VTEC is very noticeable with the butt dyno and auditory senses....
