Hey thanks man I needed that it was good to know I have the 93 si so that means I may not have to run into the ecu but just into the cluster right cause I have the p13 is this correct??

I have no idea what you're asking.

Also, why are you keeping the H23 transmission? Saving money? The H22 trans (forgot the #) is better suited for, well, the H22. Also, 5th gear is taller in the JDM H22 trans which will get you better gas mileage when cruising.

This absolutely makes no sense!!!

So what was all that "searching" you said you did?

From your post, I am going to assume that you are running the p13 in your h22 swap but you want the gauge cluster for a h22?

its not a jdm motor or trans and I know its longer I had it in my last prelude just heard the h23 was longer the the usdm h22 trans and I was asking bout the pin to wire up vtec but I got it thanks guys I went and got the pins today they are really expensive one dollar per pin so and I heard you have to switch the coil is all cause I am using the h23 harness but in your installing guide it said 92 to 93 already hooked up for vtec is what i was asking

You know we have sentences in english right?

1. It's easier to just switch to the external coil so you can stop by your local car parts store and pickup wires / distributor.

2. The h23 gear is longer but the jdm h22 has a longer 5th gear.

3. I remember reading those "pre wired for vtec" and some people were and some weren't iirc.

like I care bout english you got it but they all come with a external coil unlike the b18s and b16s and d16s so what is the black thing coming out of the distributor cap its the coil is it not??? Cause I thought it was and like i said on the civics they are internal and I was going to put a external one on so let me know??

preludatic · 05-23-2009, 02:10 PM

We're all willing to help, trust me... but your sentance structure is very difficult to follow...

shanehonda · 05-23-2009, 08:09 PM

got ya man no worries

So would it be better to run the h23 or the usdm h22 trans?? Oh and the h22 did not come with a powersteering pump does the h23 bolt up and the belts work?? I think I might rip out the ac too I never use it since I always have the sunroof open and the windows down

petern101 · 05-25-2009, 07:20 PM

^I think there are more ribs on the PS pulley on the h22 than on the h23.

shanehonda · 06-25-2009, 12:02 PM

h23 powersteering worked perfect on it man im so glad!!! Oh and I have the motor in now everything is hooked up but now I need to hook up vtec I am using my h23 harness and the motor did not come with the plugs that go in the vtec silinoid where do I find the two plugs??
