ok hey guys i have had countless integras and only one 91 honda accord...i bought a prelude si with a blown h23 engine and now i pulled the h23 and swapped a 94 accord ex sohc into the car with the h23 engine harness ......i have searched and searched and there have been other people that have tried to do this swap and everyone is shutting the swap down....im starting to realize why....the fuel rail on the f22b1 is totally opposite of the h23 (inlet is on the drivers side) and it looks like plugs are not going to fit with or there are some that just have no where to go....what do i do or is there a write up on what goes where and i think i heard something about wiring (taking pins out and putting them somewhere else).... i dunno i thought this was going to be a easy swap just plug and play and add some wires for vtec and drive an economy prelude si....guess i shouldnt have bought it but now im stuck with it.....some one please help.....i cant believe i feel like such a newbie again...should of just bought another integra...

 

Just bumping my thread because after 30 views nobody has anything to offer

 

I think people are putting h23 heads on this block ...... If people are putting h23 heads on a f22b1 sohc vtec block pleas elet me know because I keep reading about a dohc f22b engine so I want to make sure I got the right info before I start digging into it

It's easy. Let them make a new fuel line at the hydraulic/pneumatic stuff shop. Or make your own line buying proper components here for example: http://www.anplumbing.com/shop/
Which plugs are problematic?
Make some photos to let you help instead of counting viewers...

 

I think I found what iI'm looking for on cb7tuners.com under swaps there is a write up on what needs to be done... I put the h23 harness on... But I think I'm going to switch back to the accord harness because I don't have a h23 distributor....so I think I'm going to leave sohc head on just becahuse im trying to save money I know I could us anplumbing but that's almost $100 dollers just in fitting and the inline fuel filters... Will the accord harness work or will I have to modify it?

 

ok i came home and checked the plugs on both harnesses and none of them line up...so im totally stuck on what to do...this sucks

 

i will get pics up later

 

You use the harness which was originally in the chassis. Lenghten some wires to reach sensors (for example: IACV which is at the back of the manifold in F22, IAT, O2 sensor, thermoswitch, oil pressure etc.). As for distributor: cut the H23 plug(s) and solder F22 plug(s). You can find out in the manual which wire is which signal and match them.

 

Do you still have the H23 fuel rail? For the H series swaps, you just change the rail from the H23 to H22.

 

It doesn't make sense. They're exactly the same.

 

i dont have a h22...anyways i dont have a h23 distributor and the f22b distibutor is a internal coil

 

I have a feeling the problem you're having is you have an OBD2 motor. That's why so many plugs aren't matching up. Dunno if the pattern on the manifolds are the same, but maybe use the H23 injectors and fuel rail? H23 harness, and find an OBD1 F22B1 distributor

 

i have a obd1 engine its from a 94 ex accord

 

its a obd1 94 accord ex

 

the prelude firewall plug

accord ex plug

external coil plug on the h23 harness...but the f22b1 distributor is internal

misc plugs i havent found a home for yet

prelude the way i bought minus the hood being on the car

the way the prelude sits now with the f22b1 engine in still not running

 

So, with the H23 harness on the F22B1, the only plugs that don't match are the distributor plugs? Perhaps an external coil F22Ax distributor will work. Or swap the plugs from the Accord harness. Those wires that go to the coil are still used on the internal coil distributor. They're just part of the other plug

 

You didn't use the H23 harness. That's why you're in trouble.

 

h23 harness is installed i jsut took pics of the f22 harness to show you the differences in plugs

 

ok so i put another h23 engine in and the timing belt is loose as hell and there is a hole in the oil pan..... buying a new belt and taking off the oil pan to weld the hole shut....another note...if you are to put the f22b1 engine in your prelude people are taking a 30 amp fuse and putting it in the plug for the external coil....so you can use the the f22b1 distributor....

also if you dont want to hack your h23 harness up you can take the h23 intake manifold and supposively it bolts right up to your f22b1 vtec head....this is all stuff im going to be doing as soon as this h23 engine blows up(crosses fingers that it doesnt) we will see.....untill

 

Isnt the F22 the single cam that cam in Prelude S models.

If so you can take just about everthing off the h23 motor to bolt onto this motor.

You got the fuse thing right, and if your plugs dont match up but you know that they go together, its time to break out the soldier and get to work!

 

f22b1 sohc vtec block and h23 head do NOT go together....i have tried this and it does not work....so now my next thing i did was i heard that the h23 intake manifolds go on the sohc head...this is true...i did however have to modify my manifold and grind down an area where the vtec solenoid is located....the next hurdle was the water neck connection where the thermostat housing is located did not fit also without grinding away at the housing because of the vtec solenoid again....now i put it all back together and got the engine back in the car....now im going to have to use the f22b1 distributor but its internal coil.....you put a 30 amp fuse where the external plug is located? but what about the blue wire that goes nowhere now? could someone shine some light on this? i put the fuse in and using the h23 ecu and the car does not start...just turns over.....should i get a accord ex ecu now? or can the h23 one work for now, and i just dont have something wired up right? thanks guys

 

I hate when people have problems and never finish with what they needed help with..and i did exactly that....anyways with this car i got it running with a accord ex ecu and i had the plug wires mixed up...after i fixed that it started right up...trade the car for a 91 integra and the guy wrecked it two weeks later
