need help with d16y8 swap?!?!

[honda91efhatch]

Hey, im lookin into a d16y8 motor. Wat all would i need 2 swap it into a 1991 dx hatchback that has a d15 non-vtec in it now? Ive looked on several threads but most are about a d16z6 swap, and i kno these motors arent exactly the same! I need help?!? parts list? time? money? sources? any thing and everything will help!
Thank you

by the way the d15 engine thats in the car now is a 16 valve if that helps any

you would need the engine, wiring harness, and ecu. your tranny will fit. the intake manifold and all accessories should fit as well. I just did this swap myself except I had a d16y7.

 

[honda91efhatch]

can i run my stock ecu or do i need an ecu thats vtec compatable? wat kind of wiring harness do i need? n where can i get it?

 

[honda91efhatch]

What is the difference between a obd2a and obd2b?

 

[YBLEGAL]

the wiring is different. that's all i know to my knowledge.

True....i did the same, but im still obd0. you can keep your stock harness, unless you have a dx, then youll need to do the mpfi swap. After that the motor should fit your trans, use your mounts, youll have to modify the timing belt cover a bit, use the clutch for the trans you use which should be a 89-91 si trans, pm6(wont run vtec) ecu or obd1 conversion harness and a p28 to run vtec. If you keep your harness youll have to run the two vtec wires and there you go.

The difference in the 2 obd2's is obd2a(1996-2000), obd2b(2001......)

 

[ls/vtechatch91]

or u can run ur vtec off a toggle... and still keep it obd-0 with a pg7 ecu ...

 

[honda91efhatch]

off a toggel? that sounds kinda getto! relable?

 

[honda91efhatch]

run the two vtec wires? wat do u mean? jus soder them 2gether?

 

[philyphreak2127]

I don't think he means solder them together but this is where I am lost. I have yet to wire vtec on my swap. so now I get to learn with you. lol

 

[honda91efhatch]

sounds like fun, i jus picked up the motor 2day! wanting 2 get all my info b4 i attempt the swap!!

 

[ls/vtechatch91]

its not ghetto... my buddy had a mini me in his hf crx plus about 3500 into it... but it was beating gsr's all day long.. not stock one either.... but anyways... he wanted to stay obd-0 so he bought a pg7 ecu from the 1st gen integra... they give u about 10hp more.. than ran the vtec off a toggle.... then u could have vtec anytime u want...

 

[philyphreak2127]

damn. I love that idea. you should have him do a write up on it in the tech section. It sounds like something I wanna look into.

 

[honda91efhatch]

yea, sounds simple! do a quick write up, i jus got a d16y8 n wouldnt mine the rumble of a low idel vtec! plus it sounds like a quick fix, dont sound like it requires 2 much kno how either! lets hear how 2 do it?!?!

 

[ls/vtechatch91]

i wouldnt recomend having the toggle on under 3k rpms... theres not enough oil going threw it yet.. all u do is hook up a toggle from the selnoid and run it into the cab of the car.... takes like... 10 min if u know how too... but first swap your car to mpfi...

 

[philyphreak2127]

alright got it. and I wouldn't wanna run it that low. its more of the fact I could turn it on and off when wanted that is so attractive.

 

[honda91efhatch]

wat if you already had a p28 ecu?

 

[honda91efhatch]

theres 3 wires that come off of the vtec soloniod arnt there? how would u manage that?

 

[honda91efhatch]

could you completely surpass any ecu by doing that?
