I am rebuilding a GSR engine but I am missing alot of parts like brackets,sensors,hoses etc. I was wondering if anyone had any rear engine pics of a B18c while it was out of the car. I have been looking at the helms pics but they arent that great. I also need to know which intake manifold is OBD1 and whether or not I am supposed to have an oil cooler. There is also a sensor underneath the timing pully that I cant find in the helms and I have no clue what it is for. Any help is appreciated!

 

My '95 GSR has an oil cooler, but I don't think there's any sensors under the timing cover. Would that be an OBD-2 ('96+) CKF sensor??

Thanks for the help! I have studied those diagrams carefully and still cant distinguish the OBD1 manifold from the OBD2. I have both manifolds but just dont know which one is for what. If you look at the manifold on the engine from the back and look on the right side of the man. there are some nipples sticking out that are for coolant. One of my man. has 1 nipple and the other one has 2. This is the only difference I see looking at the 2 in person. However, when you look at the diagrams from Delray Acura it shows that all year gsr manifolds look the same in respects to the nipples. So this is confusing.

In regards to the oil cooler, I was told by a friend that only the JDM engines came with the oil cooler; if so, then I have a USDM engine which isnt set up for it. I can tell it isnt set up for an oil cooler because the main water pipe in the back of the engine should have 3 nipples sticking out while mine only has 2. Or it could be that the automatic engines didnt have an oil cooler while the manual ones do. I dont know. Either that or the diagrams are showing JDM parts which makes things even more confusing! One thing is for sure, if I buy another swap I am going to buy a complete engine instead of short short block. All of this part searching is giving me a headache. Sorry for the long post and thanks for the help!

 

my 95 gsr motor has a oil cooler. so should yours

It really sounds like you have a newer engine. The oil coolers were '94 & '95 (& I'm not sure when they quit)? OBD-2 engines have a CKF sensor under the lower timing cover. USDM GSR never had an automatic tranny.

What's the first digit of the block serial #? Stamped under the 'B18C1'...
first digit 1 = '94
first digit 2 = '95
first digit 3 = '96
etc...

On those parts drawings, also check vacuum tank/tubing. There's some difference in the EVAP purge valve tubing, so maybe that can tell you which manifold you want.

The one with two nipples is OBD-1.

The one with one nipple is OBD-2.
[see water hose diagram...it's all there]

The EVAP purge solenoid mounts in between the #2 and #3 runners on OBD-2 manifolds. You should see a pair of plateaus to facilitate the mounting of hte purge solenoid there.

The EVAP purge solenoid on OBD-1 manifolds uses a machine screw to mount the solenoid just to the outside of the #4 runner....somewhere in that area.

You can also look at the throttle body that came with the manifold. If it has a huge, long nipple jutting from the top (above the barrel), then it's OBD-1. It's a part of the OBD-1 evaporative emissions plumbing that the OBD-2 throttle bodies don't have.

Thanks for the help this is great info guys!
Ok so it looks like I have some miss matched parts then. Since I'm going to be running this engine obd-1 then I am assuming that I dont need the CKF sensor so I can leave it off. Should I change the timing pulley to that of a 95 or can I leave it the same. The one I have has an extra gear to facilitate the CKF sensor.

Ok looks like I put the right manifold on according to the 2 nipples. The vaccuum tank was already on my manifold so will asssume that it is OBD1 as well.

Should I run an oil cooler if I want the bar cert.? If so than I think all I need is the rear water pipe and I would have to figure out how to get the nipple off for the current oil filter setup. I already have an oil cooler.

 

I have some pics from the back in this write-up that I made. I might have some more pics if you need them and I can post them.

 

Thanks those helped alot. I think I have pretty much everything figured out except for one. On the thermostat case there are some nipples. The one I have has 1 nipple while the one shown in both the 95 and 2000 integra diagram both have 2 but the part numbers are different. So which one should I use. According to the hose diagram one hose goes to the head while the other meets up with the breather piping that goes into the intake. And if I use my current one how do I connect to the breather that goes back into the water inlet (where the upper radiator hose connects to). Sorry for all of the questions, I'm just trying to get everything right!

 

On the block under the "b18c1" its stamped "3S02149" so it is a 2002 block correct? I was told that the head is from a 2000. So in order to keep things legal with the REF would I need to keep everything OBD-2. I already have an OBD-1 ecu on the way so I dont want to go OBD-2.

 

I can think of several different ways to make it work.

You could use an OBD-2 intake manifold, OBD-2 TB, and route the PCV breather coolant line from the TB to the upper radiator hose housing.

Or, you can just cap off the smaller coolant nipple on the OBD-1 intake manifold and run the PCV breather coolant hose from the TB to the upper radiator hose housing.

You can also use an OBD-2 TB with (preferrably) an OBD-2 intake manifold. Then circumvent the IACV-TB-PCV breather coolant path and route the line directly to the upper radiator hose housing from the main water hose.

I won't pretend I know what's needed to make the REF happy.

 

Oh duh 96'! What if I used the thermostat housing from an LS? It has 2 nipples and I could hook it up the way it is supposed to be. I think I has one laying around anyway.

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by mekanism &raquo;</TD></TR><TR><TD CLASS="quote">... I think I has one laying around anyway. </TD></TR></TABLE>Try it. That's a lot more certain than us guessing whether it'll fit.

 

OK I will try it. I was thinking of just using some universal hose to go from the thermostat housing to the water outlet instead of buying the metal piece that connects it to the valve cover breather. OK so I think I have it all figured out. I looked up some prices from Sunnyside and for everything I need it will be around $100 so its not too bad. Now all I have to do is figure out the wiring!
