JDM DC5 K20A swap into a 2001 EM2

[DA9_GSR]

Update,

Got everything buttoned up and the car won't start. I get a clicking noise from the starter relay, but the engine won't turn over. Turns out, through voltage drop diagnosis, the ground side of things isn't up to snuff. I did some research on DC5's and EP3's starting / charging system grounding and here's what I found:

All vehicles have three ground cables:

1 - from battery negative to body
2 - from battery negative to engine
3 - from engine to body

We had only the ground cable from battery negative to body and it didn't start. We then added a ground cable from engine to body and it still didn't start. We are now going to install a ground cable from battery negative to engine and see where we stand.

Any of you K swapped EM2 guys run into something familiar? Any pointers?

Cheers,
Ryan

add another one from the trans to the body also if you don't have a ground from engine to chassis it will use the next available wire it finds as a ground and ten to burn it up I burned up my stainless steel braided clutch line because I forgot to hook up one of the grounds

I own an EP3 so I took a look under it's hood today to be able to compare. The EP has ground wires:

1 - from battery negative to the body
2 - from battery negative to trans bracket that bolts to trans
3 - from passenger side engine mount to body

I'm just going to mimick this and hope for the best.

Cheers homie! Thanks for the help.

Found the problem,

The starter motor "S" terminal connector was unplugged.
Reattached it and the car started right up!

WOHOOO!!!!

Update:

Done!

Everything is finally done! We got all the battery relocation cables hooked up. The entire interior is back together. I even drove the damn thing. What a hoot! It pulls pretty nice. Gotta love the 6 speed EM2. Wohoo!

I have a ton of pictures to load. Will be posted at a later date.

All done!
Here's some pics.

Hey I have a question when it comes down to the k20 swap... I already did the install but the issue that I am having is the temp gauge. Temp still reads cold and not registering thru gauge.

Did the following but still no luck:


- I swapped out the Rsx temp sensor and replaced with the civic temp sensor.
- reswapped the civic temp sensor back to Rsx temp sensor (still no luck)
- re-checked both sensors both are working fine.


Background info: used a plug and play method so no wires are cut. Used k-tuned wiring harness... Everything works ie: rpm, speed, fuel but not the temp sensor.

Any suggestions would be most appreciated?
