I found some shots that Matt sent me while my car was being built.

Huh, these are interesting pictures. I was under the impression that the cutting of the frame was fairly minimal for the K20. This is way more extensive cutting and notching than I had to do for a VR6 swap.

So I was test fitting the belts and pulleys. It would appear that my belt is far too long or I’m missing a pulley. I’m not running AC(for now) so I’m not sure if that’s what the issue is here. Almost ready to put motor in and start the car. Coming down to the wire so I appreciate any help on this one

I replaced PS with/AC, but same belt routing, I just added an extra idler to keep the belt inboard

What battery is everyone running on their k swap X? Is the standard sized X battery plenty?

Stock (87) size battery - MT24 I think I had in mine

So working on my fuel pump wiring. I’m running an aftermarket pump and was planning on using the aftermarket ecu to run the fuel pump since it’s tied to the engine and can adjust as needed. Not sure how everyone else here has done it. Did you shut leave the factory fuel pump relay and wiring in place and have the fuel pump run all the time? My harness for the k20 has a ”fuel pump signal ground” output on it and I’m not sure if this needs to go to the fuel pump or to the signal terminal on my fuel pump relay.

I used the Honda EMS, that controlled the pump. Your aftermarket (EMS) system should indicate the appropriate connection for the pump and (supplied?) relay to run correctly. Do you have a schematic that we can look at?

I figured it out for now. Used a seperate relay that is just active when the ignition is on. It will be fine for now at least until I get past this rally next week that I’m trying to go to.
