I need help with F20b

[cb7_orlando]

I need basically a parts list for the f20b motor...like what to use and what not to use and what parts i need from an h22/h23 etc. the help will be appreciated thanks.....i have just the motor and the harness it came with i know for a fact that i need h22 headers and im using the h23 upper plenum

I don't really know what parts you will need or what will interchange but I do have an OEM JDM intake manifold and some other misc parts laying around.

I used the H22 upper plenum and throttlebody. The H22 driverside engine bracket and H22 powersteering bracket. H22 Header also but you mentioned that already. Im saving up now for a P72 from I think Phareble and getting it tuned by a local shop (Speed Factory). Im using the F20B injectors and Fuel rail. Elimanating the injector resistor box. Use your engine wire harness and adapt plugs from the F20B harness. Thats if your going OBD1? Also used H22 waterpump, H22 timingbelt, H23 manual tensioner. Oh and dont forget the 11MM washer behind the tensioner you can get it from a honda dealership, Part #90140-P14-A10

Ummm, not sure what all exactly you need. Everything on the exterior of the engine will fit H22 parts.

thanks and kirk90 how did u use the injectors and fuel rail the fuel line is on the opposite side? and to make things real simple i just went with the upper plenum and its bigger for some odd reason so i can stay obd1 my next problem is the lower plenum my f22 injectors are like double the size of the f20b so what injectors can i use so i can stay obd1 and use my original harness without cutting anything??will h22 obd1 injectors work with the f20b mani?

We have a place in town that makes up high pressure fuel and hydrolic lines. Im getting a fuel line made to reach. Its a bit more expensive than going with a U.S. fuel rail. So if you go with F20B lower plenum you'll have to go with F20B inj. You can also go with OBD1 H22 Inj. and the H22 lower plenum. Hope you realize that you will have to do some wiring modifications?

I don't think that's true. I used an aem fuel rail but had to change out the studs that hold the fuel rail on from the h22 runner to the f20b runner and used h22 injectors. I would assume that you can use the h22 fuel rail with h22 injectors fine on the f20b runner with h22 top plenum.

You might know better than I ? from just fitment experience that the F20B lower plenum inj. ports seem to be shallow and that is why I said F20B lower plenum and F20B inj. Now maybe someone can get them machined to accept the H22 inj. ? I havent tried testing this out H22 inj. and F20B lower. As my F20B is still on the engine stand waiting on ecu, wiring, clutch kit, Exhaust mani. But yes you will have to change out fuel rail studs.
Plus I think jhondayaaj has a running F20B in his whip!

f22 fuel rail so save getting a extended line?
