hea guys i got a vx hatch witch is v-tec-e and im teporarally swapping in a d15b7 while i build my mini me... so is swapping a non v-tec motor into a v-tec car a easy and possible task?

Midori

just change the ecu and you are good to go ! P06 is what you want. zip tie the extra wires in then engine and don t worry about the ecu side. Plug it in as usual.

real difference, definetly is the ECU, dont cut or take off any wires really.. theres only 1 wire that makes vtec its usually the green plug *on a d series*, zip ties are definetly your friend.

midori, is the po6 not a v-tec ecu, jdm d15b?

Midori

P06 - d15b7 for sure!

P08 - d15b (I think...)

I say screw building a mini me....just stick a ZC vtec in it along with a Si trans.

Although vtec e are slow, the trans they are connected to are even slower. In the end you would benefit more from a tranny swap then a head swap at least for the price.

Si transmission swap 150$
Head swap 300-400$

apologies.. but i cant stand this ... its vtec... .. BAd spelling.. no cookie for you.

you'll be fine. I've done non-vtec swaps into vtec cars before and all you have to do is leave the 2 extra vtec plugs unplugged and get the proper p06 ecu to avoid any CEL's.

The only other problem I might see you running into is the o2 sensor. The VX has a 5 wire o2 sensor, whereas the every other model uses a 4 wire o2.

my bad on the vtec spelling......
and sorry for the newb question to follow.

i was sold a computer that has a sticker on it saying its a p06, and i opend it up and there is a sticker on one of the chips that says "d15b". the guy told me it was chipped for vtec by tecnotics, is that possible?

yeah im pretty sure u can chip any computer to run vtec.

then again im not even 60 % sure

Clean95d16

it is true depending on the chip you can definetly chip it for vtec, the only thing that sucks it most days its hard to notice or hear vtec unless you got a keen ear. I havn't heard of many chipping the p6 for vtec... simply because its usually cheaper to go to a junkyard and grab up a p28 but definetly go do a couple "hole shots" and youd be able to hear it engage
If you really wanted to test it, you can always get a dope **** JDM vtec controller
toss that baby on and set it to engage earlier listen for the tone.

yes, i've converted literally hundreds of non-vtec p06/pr4/p75 ecus to vtec over the years. You have to chip the ecu at the same time as adding the vtec components.

Vtec controllers are ****. The easiest way I find to test if vtec works or not, is unplug the vtec solenoid, drive the car, then plug it back in and take it for another drive. Without vtec working you'll definately feel the difference.

Clean95d16

agreed zeeman , toss it on a friends car that has vtec thatll test it as well.

dreamr

ok so another newb question....can i still run my vtec chipped p06 ecu with my non vtec d15b7, will the vtec just not work? or is the mapping all diffrent???? or do i indeed haveto buy a new ecu?

Midori

yeah you can run it with the chipped ecu... it just won't recognize the vtec part cuz it isn't plugged in.

if you have a vtec map on the chip and the vtec solenoid/pressure switch unplugged you'll get a CEL for code 21 and 22. You just need a chip with a stock p06 (d15b7) map on it.
