Hi Honda Tech , newbee ..

I currently made a AT to MT swap on my Ek Sedan . had a y8 intake manifold on my d16y7 stock engine .. I'm still looking for a good deal for a y8 vtec head cylinder to make a minime swap . but for now im using my y7.

It seems i can get the 5spd ECU for a y8 first rather than the head .


Can i use the y8 ECU on my y7 so i can just install the head when it comes ????

no . wiring is different and there are more sensors on the Y8.

umm im running a y8 ecu on a y7 motor

but I am also running the y8 manifold
(2wire iacv)
It does throw a cel for the vtec not bein plugged in but works great

I should also note my car originally came with a y8

Mini me.....


Pfft..


If the car came with a Y8, get a Y8 and drop it in..

The mini me is not a good move. Do some in depth research.

IACV and Injectors are a big issue when it comes to the cars reliability (idle and gas mileage), there could be more but this is as far as I know.

@OP Answer these questions
1) What Injectors are you using, Y8 or Y7 injectors
2) What kind of Y8 Intake Manifold is it, a 2-wire IACV (Manual) or 3-wire IACV (Automatic)

Those answers can determine which ECU you should actually be running, but just finish the full swap so you don't encounter any further problems.


^ Those who want the loud *** VTEC/bragging rights or ~20 horsepower would do it, or even for boosting.
Personally, I'd just do the swap because of the 2-wire IACV making it easier to tune a boosted motor. OBD1 conversions work on 2-wire IACV wiring IIRC, and all would be needed would be a y8 manual intake manifold, convert the IACV from 3 to 2-wire and the plug, then adjust the pin-out at the ECU harness, grab an OBD2A/B to OBD1 conversion harness and a chipped OBD1 ECU and you're ready to tune (assuming everything else is set in stone)

Thanks Guys for the Help ,

I'm running a y7 head with a y8 intake manifold (2 iacv wire 5spd MT )with y7 injectors .

so I can't use the Y8 ECU . well I will just get the y8 head and ecu together.
thanks guys

If you find a good deal on a whole swap Id go for that and sell the parts you dont need

for me personally I cant take the head off a perfectly good motor without doing the rings and bearings since its already half apart
