im going to put this motor in my 88hf. I dont have any harnesses or anything to run vtec. I dont want to run it. I just want the 99 motor to run in the car. I have no dist on the d16y8. I have everything else-complete. What do I need Differently not stock on the HF to make the motor run?
Please help-this will be done tommorow morning

 

that should be pretty easy, if you really wanna keep it simple, your hf dizzy, and manifolds should bolt up to the y8 head, and run your harness and ecu and everything, cable tranny mounts right up, can't use the y8 flywheel though because your '88 uses a smaller clutch which uses a smaller pressure plate bolt pattern, bolt your '88 flywheel and clutch assembly onto the y8 if your using your stock '88 hf tranny, use your axles, hubs, etc.. you'll probrably have to relocate your temp sensor and someother small things but it should run, i have an obd1 motor (not vtec) in my car with obd0 stuff bolted on and it runs fine

 

i'd recommed eventually getting at least all obd0 SI stuff to run the car and an SI tranny for an awsome dirt cheap way to wake up that super light rex

 

if you dont run vtec its gonna be running on low cam all the time and be slow as ****. convert to obd1 and get a vtec edu or at least get a vtec controller

 

i dont want vtec. so put manifold and dist on motor from hf? then wire it up?

 

GHET-to engineering at its finest.

Your tranny and exhaust manifold will bolt to the D16y8. I'm not sure about the intake manifold. Worse case scenario, you do a y8 manifold hack job.
Your HF distributor will bolt to the y8 head. Use as much of your old HF wiring as possible.

Bad ideas
1. The HF ecu (fuel/timing maps) is meant for running a smaller, leaner engine. Too lean a mixture can blow an engine quick. Especially in Houston summer heat.
2. No vtec. While the y8 low cam is punchy at low rpms, it peaks early and power delivery drops off dramatically at 4500rpms. Which may be what to you're used to in an HF, but its like putting a v-8 in a car and leaving the spark plug wires disconnected from two cylinders.
3. You'll probably have emissions issues. Even if you reconnect all the emissions equipment, the tune is going to be too far out of whack to be adequately corrected.

 

You WILL NEED the wiring plug & lead wires for the temperature sensor that is now located on the thermostat housing.

You can not use your old radiator fan switch sensor, and the new plug is different.

 

I can't get the vtec harness, ecu, jumper cable to wire up vtec. i need the vehicle to run. Which harness can I get right now that will help out this swap easier? Get a vtec harness from a 92-95 civic?

Use the stock crx hf wire harness you got..like people said just use everything from the old motor ,,dizzy,manifolds,tranny,mounts,etc...IMO you should atleast get a pm6 ecu though..cause atleast its 1.6 and you can always chip it for vtec later on.

 

Since i'm going to get an obd1 dist... which wire harness do i get to wire it up?
