Does anyone have info for an h22a4 to h22a5 swap? Please help..

I bought a motor recently with 56,000 miles from JDM engine pro. From what I read the engines are similar only differing in compression ratios. I treated it like an h22a swap keeping everything OBD II. The car fires and tries to start but wont. Every now and then it will stay running for a few seconds but dies.. Am I missing something here? Do I need the ECU from and a5? Please help..

A5 is EDM engine not JDM

theres some different seonsors etc (like no crank position sensor in A5) so it might not run with USDM ecu

did you rebuild it first?

I swapped the oil pump housing from the a4 to the a5 to accommodate the crank position sensor. as far as I can tell and have read the h22a5 is just like the h22a in all regards except for a different ECU or compression ratio. I swapped everything I should need for the conversion to run OBD II alas I'm still here lol

Fuel Injectors.
Crank sensor.
Water necks dont use water sensors.
