i just swapped in a bluetop h23a vtec into my 98 prelude, i did the 4 wire splice for tdc crank sensor, i swapped my h22 vtec solenoid over to the h23a vtec do i still need to do the skywire splice for vtec to work?

 

What skywire you're talking about? Never heard of this before.

 

which distributer are you using..

 

im using the h23 non vtec dizzy so i could splice in for the sensors that use to come out of the oil pump, i switched my h22 vtec solenoid onto it, im running a phareable ecu, in the paper phareable sent me it says the jdm motors dont have pressure switch for ecu you have to do the skywire thing, but if just put usdm vtec solenoid with the pressure switch will vtec still kick in

 

You can run the vtec pressure switch wire from the ecu to ground as a temporary measure but it's not at all hard to wire it so might as well do it. You can use any vtec pressure switch for a p13 I believe. Only certain jdm p13 motors don't have the switch. Most do, I think it's the euro r's or something like that that don't.

The h23a vtec uses the h22 head.

 

I would do the skywire. I was having a problem with my pressure switch a while back and since i bypassed the pressure switch no more.
