Prep Work for New Engine


Replace the Civic fuel pump with a GSR one. IAS included the fuel pump in the swap.
Use the fuel return line for the GSR.
Use the outlet heater hose from the GSR because it is longer than the Civic. I recommend taking this hose off before putting the engine back in. However, you can keep the Civic hose from the firewall to the inlet valve.
The inlet heater hose from the valve to the engine should come from the GSR.
I bought a stock intake tube from an older GSR, but the breather tube would not line up. For some reason they changed the location in 2000 so I had to get one for an older year. If you run into this problem, here's what you need from the Acura dealership: Part#10194, Illus#008, Name:PIPE, BREATHER
Reuse the Civic driver's side mount studs for the B18. You'll need to use some pliers to twist the stud out.

Reuse the Civic upper tranny mounts and rubber.
You will need an Si or Del Sol A/C bracket for the B-series block. However, keep the Civic motor mount.
You will need the Integra lower tranny mount, but keep the Civic mount for the chassis.
This is the upper tranny mount for the Integra, which you will not need.
Here is the upper tranny mount for the Civic which will need to go on the GSR tranny.
The reason why you need to use the lower engine mounts for the civic is that there is a plate on the Integra mount. This plate gets in the way of the hump in the chassis (shown in the next picture)
Here is the mounting point for the lower mounts. Notice the bump in the middle which will not accomodate the Integra mount unless you cut it.
Locate the throttle cable through the firewall. Just twist the black thing 90 degrees and it will come out easily.
Once twisted, you can pull out the cable and replace it with the Integra cable.
I noticed that the cable was still too long even after fixing it to a bracket on the firewall. So a simple and easy fix was to add a 1/2" nylon spacer on the cabin side of the cable. Afterwards, adjust the cable on the throttle body and it'll be good as new.
Once I got everything in and all the mounts on, I added the usual engine oil, radiator fluid, and tranny oil. I was curious if the tranny fluid had been drained and to my surprise there was still a lot in there. This is what came out...good thing I checked! (pic caption: yes, this is old tranny fluid!)
