Re: [FAQ] How-To: K20 into 92-00 Civic/94-01 Integra (poison)
<FONT SIZE="3">Cooling the K20:</FONT>
Can you please explain how you wired the two sensors to the k20 engine harness ?
That part has me confused
This is a very easy process, but as always, ensure you have good connections with the clamps, and ensure the hoses are not chaffing on anything. I would recommend using new hose clamps with the bolts on them, rather than the old tension clamps.
Radiator Installation:
Most K20 hybriders simply re-weld their radiator brackets to the driver's side of the radiator support. If you have done this, and have additional pictures, please post more information! Thanks!
I personally am running the ETD Traction bars with the radiator brackets. But the theory is the same as any radiator installation. Doesn't take much to install a radiator (we all know this)
Since there are so many options, I really can't narrow down what you are doing. But I'll explain the basics.
[*] Standard dual core half-size radiator - Simply place the radiator in, along with your top mount (I personally used a Karcepts radiator bracket):
Brackets from below:
Ensure the radiator is secure. Next is to connect or wire your fan. Simply connect the two wires together. One is obviously positive, and other is negative. Secure the wires, and make sure they aren't exposed to any heat or have potential to be stretched/ripped.
Radiator Hose Installation:
[*] TOP HOSE - I personally went with AutoZone hose part # M248 for the TOP HOSE (Thanks Karcepts!)

Pic of mine installed:
With very little modification, the hose goes right in!
Another option you have for the upper radiator hose is an RSX Type S TOP hose. (Don't currently have photos for that)
[*] BOTTOM HOSE - I personally went with a 94-01 Integra radiator hose (AutoZone part # XL-588):
I just simply cut a section out and fit it into place:
Another option you have for the bottom radiator hose is 99-00 Civic Si TOP hose and use it as the bottom hose.
[*] Fan switch (ECT) & Coolant Temp Sending Unit (gauge cluster):
You will have to either salvage the ECT Fan switch sensor and the Coolant Temp sensor from your B/D series engine, or purchase them from Honda.
Here are pictures:

ECT Fan switch:
Ensure you also take the plug and leave some wire for it. You will need to use the plug.
There are several options you can do. You can either get the HASport radiator hose insert, or use an NPT fitting, or use other means to install them correctly. There are other hybriders that have used RSX radiators and simply installed them into the radiator like factory RSX's have them. You can also purchase a Hybrid-Racing radiator that allows for the sensors to be installed into them.
For me, I chose the HASport radiator insert:
Simply install the two sensors into the hose insert like so:
Install them on either the upper or lower radiator hose. I personally installed it into the top radiator hose since it's the hotter hose of the two, therefore the fan comes on sooner.
Picture of hose insert installed (without clamps yet):
Place clamps on it. Then wire them according to whichever wiring harness you purchased. Do not forget to ground the hose insert to the engine/tranny!
As for heater hoses, I have seen people fit factory Civic hoses to the heater core, and also people have fit RSX hoses. A lot of types will fit and go directly towards the heater core.
You have completed the cooling task!

First off, I want to thank nikos for referring me to a great guy who helped me 100% through this process. User on K20A.org "Toda Racing RSX" has sat down, and let me do exactly what I needed to do to get the K20 to start. For a good 8 hours, I was checking over EVERYTHING to try and get the K20 to fire up. And all I had to mention was the fact that it was an automatic.
100% credit goes to Toda Racing RSX. I can't thank you enough man!
Now it's my duty to help everyone else out! If you have an automatic, this one is for YOU!

- Getting the K20 fired up
So you've done everything you need to do, shift linkage, fuel, oil change, transmission oil, spark plugs, everything is good to go. But the starter doesn't kick over. This is due to the automatic is wired slightly different than the manual.
Very simple process. You need to cut the plugs off of your automatic shifter console:
Two wires need to be jumped in order for the engine to start. This is for the shifter solenoid. They are the YEL and GRN wires:
Splies those two together, solder and heat shrink and clip the plug into the factory harness.
Then you need to splice the GRN/WHT and small BLK wire together:
Next is the large BLK/WHT wire and the large BLK/RED wire. Splice those together:
That's it! Start up the engine and make sure everything is secure..
Stay tuned for reverse light installation!
