Civic EG

is it possible to swap over the motor into my car? its coming out of my 92 integra and into my 92 hatch? i know i would need a hydro tranny but what about engine harness? is the motor obd0 or obd1?

yes it will swap over. what ECU is in it? That will tell you which OBD system its running, PR4=OBD0, P74=OBD1.

ill let you guys know in a while the ecu is still in the car. im finally gua get rid of the d series idk if you guys remember i had posted that some guy wanted to trade engines my stock motor for a b20. but i have an ls motor here at the house that my bro in law took out of his can and i agree'd to give him the money instead of looking for something more expensive. but will post up soon..

yea its a pr4 so what nxt? how do i convert to obd1?

92 Integra's are OBD1. You can use the OBD1 PR4 thats present with your swap.

So to answer your questions:

use your stock engine harness, and modify it to fit. you may be able to use the integra engine harness, but I am not sure.

yes, it will swap over. you may also need the driver side engine braket (the one that bolts to the engine and the rubber mount) from a 94+ integra or B Series Del Sol

the engine is OBD1

PR4s only came OBD0 or OBD2

P74 and P75 are the OBD1 units to use.

You're completely wrong.

PR4's did come OBD0, OBD1, and OBD2a Flavors.

P74 and P75s from are more commonly seen as they come from the 94-95 Teggy. I personally have a P74 ecu in my JDM B20 Delsol. However an OBD1 PR4 ECU could run it as well.

This is correct.

Since your swapping into a EG Hatch, you want to use Teggy moutns, Especally the Rear T Bracket, the Sol one only works in Delsol's.

Personally never seen a obd2 pr4. What did they come in?

According to the Honda-Tech ECU List. It came from a 96-99 Integra, Therefore it would be OBD2a.

My Mom's USDM 2001 Integra LS has an OBD2b P74 in it.

I have never seen a OBD2a PR4 in the US. They must be from a Foreign Country. Its possible they were in the US or Canada however I havn't seen one.

thanks for pointing that out, I am all open to finding out new information. (I didnt see a PR4 OBD1 on any of my lists)
How about backing it up next time. I know Chrono explained it, but back your own facts up.

I most definitely will. When I'm not surfing with my phone.

Here's an OBD1 PR4 for sale.

Awesome

Next question would be how would I know if the pr4 ecu is obd0 or obd1 cuz for sure the engine harness is different cuz one if the plugs won't match.

The numbers on the ecu are the following : 37820-pr4-l11
492-102060 ABL

Well, to determine if its OBD0 or 1, you'd look at the plugs on the ECU itself.



Not sure how reliable this is... but

According to the link, you have a manual OBD1 ECU.
