OBD2 H22a4 Engine into 1994 OBD1 VTi Accord

[ryanpatrick42]

Hi everyone,

I'm fairly new here and have recently gotten a 1994 Accord VTi manual with a F22 engine in it that needs a new head.

I'm just looking at what's needed to drop a H22a4 Vtec engine in and replace the original F22?

I know that my Accord is OBD1 and the H22a4 Vtec is OBD2, and from what i've read this is what I need to do...

Use H22a1 OBD1 Distributor
Use H22a1 OBD1 345cc peak and hold Injectors
Use P13 Manual ECU out of a OBD1 Prelude
Use Alternator / PS pump and brackets off F22

Do I need to use Prelude engine mounts or will it line-up with the accord mounts?


Is there anything i'm missing? Please feel free to make suggestions! :)

get a odb1 h22a jdm engine, easier, and 10hp more than h22a4, you don't need to change the mounts afaik, you will need to wire up couple more sensors to ecu, and might need to add couple pins to the ecu plugs.
