Generating maximum power from d14 with d16 dual vtec head

[pwuser159050324756]

Hello Aoa
I have a 95 civic with d14a8 and has a d16 dual vtec head on it the car is currently stage 1 but iam not satisfied with its power what can i do to increase its hp upto atleast 140 the car is currently running on a d14 ecu and beacuse it has d16 dual vtec head so the vtec is wired to a button

Vtec wired to a button like nos? Funny but i always think of doing something like that.
Now. Ecu will not adjust the AFR and timing right with different head, for not what it was mapped. Ecu will be going nuts with that vtec button pressed.
First thing you need is a chipped ecu.
2nd d series does not has that much potential staying n/a. Until you are throwing extremely aggressive aftermarket cams with b series transmission etc etc.
You want total 140 figures or want to add that in current power?
And that's not what stage 1 is.

Bro the ecu is of d14 its non vtec so the button is added temporarily so the vtec can engage as the head is d16 dual vtec

[Hassan1991]

Yes i got that.
That's why i said ecu will go nuts.
You need chipped ecu, that should be your priority right now. You will see huge difference in performance after a proper fuel/ignition map.

So i should get a d16 dual vtec ecu and get it p08 chipped right ? Will it also affect its fuel efficency

[Hassan1991]

There are many other ecu's which can be chipped. P08 is overpriced for no reason.
If you care about fuel efficiency swap a bone stock non vtec d16y4 with original ecu.
Performance and fuel efficiency are 2 different things.
