i am building an h23 and want to go to an h23 vtech but want to know what i would have to do and i am thinking about the long run i have a h23 board out and sleeved so it is techniclay a 2.4 now with forged rods and pistons running 9:1 compression i am wanting to put the h22 head on for the extra air flow and better cams but i have a few questions i am going to get a turbo as next step in the build and am wanting to know if the h23 ecu will work or will i need the h22 ecu and i am thinking of not useing the vtech and wanting to know pros and cons to if i use it or not. also wandering what to expect i know it cost and is alot of work to build one of these but i already have the start so i might as well finish just wanting some help in this next step of converting the h23 to an h23 vtech so any and all information would be helpfull

i would say post in the turbo section to give you a little better tech support.

 

Get Hondata or Neptune or start reading at PGMFI.org

If you try to run it on your stock ecu, things are gonna break real fast.
