Jdm H23a Vtec.
i'm swapping this in very soon and need some questions answered.
My current set uip=92 prelude si. Jdm f22b 5 spd.
1. What kind of Ecu will i need? this engine only comes Auto so theres only ECU for auto and im going stick. i'm going to keep my old tranny(5spd) and bolt it on the h23vtec. which i think will work since all h tranny are interchangeable.
2.i know im going to need a OBDII - OBDI wiring harness conversion. will i need the OBDIIA or B??
3. My current engine is Jdm f22b and it is direct replacement for the USDM H23 so the h23vtec will mount right on?
Thanks for your help.

this is something i've been wondering for awhile also, but i remember reading on here before about a way to convert auto ecu's to manual by moving a resistor or something.

really not sure, but there is a guy on here who just did this swap and there is a thread on here about it so check that out.

yes thats right with the exception of the f22b not having a knock sensor, and yes the h23a should mount to any f (except s2000 of course) or h series tranny.
