Background: last summer I bought a 1990 Honda Accord ex for 700 dollars with 130552 miles on it transmission replaced engine rebuilt and both axles rebuilt at 100k . It has bigger injectors and headers with the head of a h22a on the the regular block(f22a2).

I was wondering what i would need to upgrade when I turbo the engine? I have seen threads where it says fuel pump but others say you don't have to same thing with ecu.
​​​​​​Eventually I am going to do a full, from the ground up h22a engine build try to see if I can hit 6-700 hp

Depending on power levels and such, it's a lot of work. Upgraded pistons, heads, piping, ECU, injectors, fuel pump, etc.

 

If your planning on running this set up, the fuel pump is the least of your issues. There will be a lot of work required to get the head to sit on the block. The stock pistons of the f22a will not support that power level nor longevity with boost period. (Ask me how I know). As for saying you want to go turbo, then the injectors and header shouldn't matter since you will have to run a turbo manifold and upgrade the injectors to support the fuel demand of the increase in airflow.


That article above has a lot of bad information. You do not need to install a resistor box, as the Accord already came stock with one. You may have to actually uninstall it to run bigger injectors. There is no need for a vacuum manifold, as there are plenty of ports on the stock intake manifold to get vacuum sources from. Unlike the civic, for the accord in, order to access the fuel pump, you either have to cut a hole in your floor or drop the tank. That access panel in the trunk is for the fuel level sensor. That guide is also for a honda civic not a Honda Accord.

Not worth putting an H22A head on an F22 block even if you got everything for free. They're prone to oil leaks and other issues because there's a lot of misalignment and hackery that goes on.

Just get a full F20B for cheap from an importer.
