i have a Vtec-e 1.5 SOHC can anyone tell me more about this motor???? Is it the same as a Vtec motor wats the E means? tell me all u can about that motor.

1. what kinda headers do i put on this motor?

AHHVTEC · 03-27-2007, 01:35 AM

yes its vtec but its meant to save alot of gas, vtec e ..economy it has less power than a non vtec dx motor,, its junk in other words

Calesta · 03-27-2007, 11:10 PM

Actually, it's not junk. It has nice geometry, has a wonderfully efficient head that can make a LOT of power if someone does some work on it, and it's just cool to be able to say you have a D15Z and roasted someone.

Header fitment- I think any D series header will work on it.

Walterronny · 03-28-2007, 05:27 PM

so vtec-e wiring is the same than vtec?

killercannible · 03-28-2007, 11:59 PM

Alot of what makes the motor efficient is in the ecu and cam. You can easily put a z6 cam and p28 ecu in it and it will run just like a z6. I also want to point out the cool rear bumpers on the vx's, they have a cool wind guard that goes from the bumper to the chassis to reduce drag

. No need for those gay looking diffuser thingys.

Walterronny · 03-29-2007, 05:55 PM

so the wiring is the same , vtec-e and vtec right? just change ecu and cam?

killercannible · 03-29-2007, 09:08 PM

yeah, the stock ecu has a rev limiter of 5500 or something like that so that has to go. Not positive about the cam cause i only drove one and never took it apart. Also, i think the gearing of the tranny is different. Geared more for fuel economy.

Calesta · 03-29-2007, 10:51 PM

You can't just drop the Z6 cam into the Z1 engine. The Z1 cam only has 16 lobes- the Z6 has 20. It won't fit. You'll have to get a custom cam made for the Z1 engine.

if the d15z is V-tec how does it only have 16 lobes

competitiveaudioman · 03-02-2008, 11:09 AM

what bout swaping a y8 head on the d15z block? any noticeable gains? is it a direct swap?

B · 03-04-2008, 11:22 AM

it's a mini-me. search on that term and you'll find gobs of info.

LS_VTEC · 03-04-2008, 11:28 AM

What makes it so fuel efficient, are the manifolds, cam and ecu. I would just swap the head. All the money you will spend on new manifolds and a custom ground cam its just not worth it.
