i now have a h22a5 engine and gearbox which i picked up from ek9sid yesterday nice 9 and half hour 520 mile round trip

good to meet him great guy , my question now is what do i need to swap over to make this engine work in my 4th gen i no i need different injectors , wiring loom , will i need a different distributor , will i be able to use any parts off my f20a4 also will the gearbox fit in a 4th gen so many questions just wont to no what i am needing before i go to fit it as it would be nice to get it all sorted so i can just swap one out one in instead of going to put it in then find out i need parts

I rock a 5th gen gearbox, so you'll be ok there.

Making it work? Probably the best bet would probably be to fit 4th gen vtec injectors (maybe resistor box?) and UK ECU, but not entirely sure on the dizzy.

I have a 5G engine in my 4th gen. For ease of install you'll need:

4th gen injectors
4th gen VTEC engine loom
4th gen VTEC distributor
4th gen VTEC alternator
ODBI VTEC ECU

For the gearbox you'll need a 4th gen VSS.

i need to have a good look threw my garage as i think i have some injectors with the resistor box and a ecu will i be able to use the distributor and alternator and gearbox vss from my f20a4 engine , also should i be doing the auto to manual conversion on the timing belt

right i have checked my stock

and i have a set of injectors , a resistor box , a p13 ecu and an alternator so looks like i need a distributor a vss and a wiring loom

You can reuse your current vss
Also, only difference in wiring are vtec pressure switch and vtec solenoid wiring.

Someone handy, if not yourself can add it easily.

i did wonder if the vss would be the same

will have to look into the wiring as it did come with a 5th gen loom , so really all i am needing is the distributor as one is obd 1 and one is obd 2

well in that case all i need now is a distributor thats if the one on my f20a4 is diffferent and not suitable for a h22
