Need help with my Accord 99 coupe
Honda Accord 1999 coupe 2.0 147hp
I think it was a F20B5 but actually it is a F20Z1 I think..
I want to know what kind of engine it’s fit on this model without modification the electrical parts, it’s fit F23Z5 or H23A?
Or anything else?
Thank you!

 

From what I can find.
F20B5 is a SOHC VTEC.
F20Z1 is a SOHC non VTEC.
F23Z5 is a SOHC VTEC engine, a variant of the F23A/1/4 engines. This would be closely related, electrically, to the F20B5 if my information is correct.
H23A is a DOHC VTEC engine found in JDM Accord SiR wagons.

F and H engines are very similar, but are signifigantly different as well.
Most differences are already noted at the top of the page in the Engine/Swap FAQ.

Even among like engines JDM F22B(1) to the USDM F22B1 there are significant differences in the electrical side if you try to reuse the JDM distributor/intake in a USDM vehicle.
VTEC functionality is also slightly different on these engines, both use the VTEC solenoid, USDM vehicles also use an additional oil pressure switch to prevent VTEC activation if oil pressure is low.
Also there can be year to year changes, with the above F22B1 on USDM vehicls the 94/95 engines have all the crank related sensors in the distributor. 96/97 engines move the crank and TDC sensor to the oil pump housing.
Once can readily put a 96/97 F22B1 into 94-97 B1 vehicles, but the 94/95 wont work in the 96/97 vehicles without changing the oil pump housing to the 96/97 oil pump housing.

It's best to strip the donor engine to its long block and transfer over your vehicles original engine(if possible) distributor, intake/injectors, sensors as well as other components to make it work properly in your vehicle.

However, changing the displacement while retaining the original ECU is not the best. Each engine has its own timing and fueling tables. Worse, Honda F/H engins are speed density and this system is unforgiving when it comes to changes in VE from factory. An engine that is .3 litres larger may not seem like much of a difference but it will not run quite as well since the speed density system cannot compensate for any large changes.

If you do plan on using an F23 or H23 engine, it would be best to get an engine with the harness and ECU for that engine.
