Anyone who has already completed the H23 Blue Top Swap.....
My question is about the wiring harness since I bought the car without a motor I do not have the parts readily available to just swap over onto my blue top, I have to figure it out on my own and purchase what I am missing to finish. When you completed your swap did your h22 wiring harness just connect or was there some modifying done to the harness? My harness only connects to the alternator, fuel injectors, and a plug on the transmission. What did you swap over? So far all I have done is the dizzy, added the PS Pump and A/C. I’m being told I need to swap over my Intake manifold what else is there?
Honestly I don't know what the "blue top" is though I could probably figure out what you need from some pics. Anyways, when I swapped in a Euro-R I used the usdm vtec solenoid, oil pump, timing belt gear, balancer belt gear ckp/tdc sensor, fuel rail, distributor and coil. Pretty much everything plugged into where it needed to go.

ZRoEXzisTeNcE: Did you not install the 3 sensors into the crank?
Disregard in my effort to learn this Dizzy mod i forgot the 3 crank sensors are the ones inside of the JDM Dizzy. You said you have a dizzy with an external coil correct. How hard was it to swap over your ckp and tdc sensor? Also you did swap your balance shaft gears correct?

The USDM 5th gen uses the dist with the ext coil. I just swapped that over. The CKP/TDC sensor bolts to the USDM oil pump (which is part #3 in the pic above). The only gears that I swapped over were the timing and balancer gears, the two that are on the crank shaft. You need the balancer gear because it works with the ckp/tdc sensor.
If so please do share details. I am still considering that engine for a swap when my current one craps out.
No, I swapped in the Euro-R H22 red top. So it's possible that all this info could be irrelevent. I don't really know how much different the H23 is from the H22. If you're still using the 5th gen harness then you're still missing the 2 connections for the throttle body, the vtec solenoid, temp sensor, and one off the back of the block. This is off the top off my head though so there could be others I forgot.
I think it was on SCP that someone swapped a USDM H23 into their 5th gen. They might be able to help you out a little more.

Damn...thought somebody that actually did the swap might have finally come forward...I will look into the Euro-R H22 since I know nothing about it though.
Also why would somebody swap a USDM h23 into a 5th gen? Unless it is a frankenstien build (I'm not considering doing that), then there is no vtec and less hp than a stock H22. Why would anybody want to do that?
