its deff looks OBD0 by the manifold. looks like a B18A1 from 90-91 integra.

get an 94-95 intake manifold or buy an aftermarket one. and throttle body while your at it. unless you want to run a stock throttle body from 94-95 integra. you can get away with using your engine harness,
should be able to get away with using that PR4 ( i think thats 92-93 integra ECU)
need to convert the timing side Motor mount to the 3 bolt bracket with the aluminum mount.

need OBD1 LS dizzy (92-95 integra LS will work)

theres probably a few other things. im pretty sure some one will mention it.

Along with the dizzy your going to shift linkage & O2 sensor if you don't already have it. The factory O2 of the OBD0 LS motors is a one wire, you need the 4 wire from the OBD1 92-95 Integra.

The PR4 ECU is from the 90-93 Tegs and is OBD0 so your going to need to find the right ECU like a P74 or P75 (just examples you choose what you prefer of course.)

+1 on changing the IM and TB, i used the IM and TB from a B18B1 because it had less vacuum ports and was a lot simpler looking.

Disclaimer: I am not promoting the seller of that item i just happen to find it!

If the motor came from a auto teg and you want the 5 speed of course you will need to replace the flex plate with a flywheel and clutch.

90-91 are OBD0 and 92-93 are OBD1 just clarifying that.
theres minor diffrences in the ECU

the PR4 is believed to come in OBD0 and OBD1 config.


OBD2B (left 3 plugs used)
OBD2A ECU
OBD1 ECU < plugs should look like this.
OBD0 (JDM PR3 and PWO)(bottom to top)

shift linkage should be from 94-01 integra, (99-00 Si will also work)
and 94-01 integra "L" bracket
trans
and clutch/pressure plate as mentioned.
throttle cable ($15 @ Acura for Type R/LS)

i would do a tune up on that motor and replace the blets and gaskets. before throwing it in.

This is the ecu i got so it's 0bd1 rite???? an is there anyone who has swapped this into there car do you really have to convert it

- Sun Oct 24, 2010 4:46 am #219673 Whats the number on the side of the ecu? I swapped in an OBD1 LS, not a obd0.

phone pic kinda blurry ... Does anyone know what harmonic balencers will fit my engine it is missing one

- Mon Oct 25, 2010 1:35 am #219813 Does indeed look like a OBD1 ecu. The motor still has an OBD0 intake manifold on it though. Take a picture of the block, dizzy plugs and thremostate housing.

Any B series crank pully should work.

pic of numbers on the head

Plugs on head

Plugs on block some one let me know if this is a b18a1 from 90-91 (obd0) or 92-93(obd1)

- Mon Oct 25, 2010 10:06 pm #219981 Looks like an OBD-0 block ot me. But I'm not a full on expert of sorts.

And that clutch is eitheran AutoZone or O'Rielly's special. It's comparable to stock, but it won't last worth a shit. Go OEM or high end aftermarket.

- Tue Oct 26, 2010 1:50 am #220019 The casting on the head seems to place it as a 91 or a 92. Depending on the month it was made. Which puts it as a obd0 or 1. The plugs dont look familiar. What is the casting number on the pistons?


Thats a sachs brand clutch. decent, but not great.
