vtec-e?
 

i have vtec-e on my car. i was wondering is there anyway to make it same as vtec without swaping heads?

Re:vtec-e?
 

whats vtec-e?? is it the same as regular vtec or is it the economical version of it and only gives a little bit of boost ???

Re:vtec-e?
 

yep, damn economics ;D. so is there anyway to make it the same as vtec? maybe swap over something small and cheap? i dont want to swap over heads.

Re:vtec-e?
 

What kind of car is your vtec-E on/from. There is 4+ models of vtec-E I know of, but to Generally answer your question, You must get a new engine & ECU. Depending on what model you have, you should'nt have to re-wire anything.

Re:vtec-e?
 

Vtec-E is from the lean burn Civic VX. (which is where you also can find the wide-band capable L1H1 O2 sensor)
It shuts down an intake valve during cruise to induce higher swirl in the chamber, enabling a leaner mixture to ignite. Basically is sucks. :P


Forgot about that, isnt there a 3stage one (low lift, lean burn w/ one intake shut down, and high lift).

Re:vtec-e?
 

actually my vtec-e is a hx not vx. so i couldnt just put a vtec solinoid off a ex?

Re:vtec-e?
 

it's a different kind of vtec, the pins and cams are different, you would have to swap heads and ecus. here are some pretty pictures and some helpful words: http://www.leecao.com/honda/vtec/index.html

Re:vtec-e?
 

There's the VX, HX, d15b[civic vti] (I thought it had a 3-stage cam??), a newer version of the d15b, and some other vtec-e's in europe.

Re:vtec-e?
 

Yeah just swap heads. You can run it fine without buying the ECU right away. We've done this a few times. ;D

Re:vtec-e?
 

yeah, what he said

Re:vtec-e?
 

i also have a vx ,If u change the head and ecu will u still have to run a 5wire o2?Or do u run a 4wire?cause my 02 is stuffed and it would work out better if i can run a 4 wire.

p.s also what head d15b or d16z1

Re:vtec-e?
 

I'm assuming you mean D16Z6 (92-95 civic ex/si). The d15b and d16z6 are the same exact head. All a d15b is is a d16z6 head on a vx bottom end. However, I've heard that the JDM d15b uses a wilder cam than the US Spec D16z6

Re:vtec-e?
 

sorry forgot to note im from australia ,we have d16z1 in stead of z6.But anyway any body done one of these conversions??I can get a head +ecu+wirring for the price of a 5wire 02.Any idea if my compression will change for a swap like this?vtec-e has really been buggin me cause it feels like a non vtec doesnt rev and makes power down low rather than up top.How do vtec sohc feel in vtec do u feel it lock in or is it like my vtec-e.

I bought a vtec before i new of vtec-e if i could turn back time i wouldnt have bought one of the slowest civics made.
