Hi im a nooby here wanting to put JDM f20b in my 99 accord 4dr 5sp it's a vtec sohc f 23 now. My 1st Q is how bad is it to wire this combo ? also i know the f20b does not have crank sensor its in distributor anyway. Will my distributor wires go to the f20b plugs wires like red to red green to green or can i run stock diz from f23 sohc or what ? any advice will be greatly appreciated . I'm wanting to do this because i found a good deal on a f20b 5sp lsd and ecu. The guy said it will drop right in just wire in my distributor wires to the f20b plug and the ecu make up for no crank sensor,wire in 1 extra knock sensor and 3 wires from vtec to ecu. Is this true or just a bunch of crap to sell me the engine. PLEASE HELP

 

come on i know some one knows what to do. is it worth it or what

 

Its been done before. There's a guy over at Superhonda dot com who did this in his 98-01 Accord. He knows more about this. His s/n starts with something like 91Exxxx. Post a up a thread in the Accord section, and he'll help you out.

 

you can also check out cb7tuner. this swap was done in a 90 accord, there should be threads to help walk you through.

 

Ok it official i got the f20b and 5sp LSD today 3 1/2 hour ride one way to VA but i got'er just got home and she's a beaut. Damn i won't sleep tonight im excited WHOO HOO! IT'S ON
Now to get the dizzy wires figured out so i can swap'em. I think everything else will be minor other then the wiring hope you guys can help me out. This wiring thing kinda scares me! But i know (or at least i hope) someone out there can help me figure out these wires on dizzy. I don't have a clue at this point.

 

heres pics of my f20b that they sent me it was recent photos of the exact one i got i will take my own pics tomorrow but for now

Ok so im looking at the f20b wondering what have i got myself into. lol Anyway I am in need of some serious wiring diagrams. I know theres a f20b guru out there somewhere. Please LMK if you can help or have links to someone who can. There are not many tuners around my part of eastern NC. I live near New Bern NC. If you have any info PM me PLEASE.

 

Ok i was still pokein around the net and found this makes me feel like i stole mine. lol http://www.jazzproparts.com/ProductD...oductCode=F20B

anyway any one got a h22a4 power steering bracket laying around? I have read this is the one i need not sure but mine on the f23a1 looks like it will work but it's SOHC so i will not know until i pull mine and try.

Also anyone know of anything else that is a definite must LMK THANKS

 

Its pretty much the same as an H22 swap except that the Dizzy Wiring will be the confusing part.

You'll have to lengthen the IACV wire, EGR Valve wire, O2 Sensor wire, and the FIA solenoid valve wire. Also, you'll need to swap out the upper radiator water neck from your old F23 to the F20B; since, the F20B doesn't come with the sensor built into the water neck. You'll need to wire up Knock & IAB sensors as well if you're using the stock JDM F20B ECU. Those are the ones I remember doing. There might be a few that I'm missing. I have no clue on how to wire up the dizzy; I figure it might be the same since both are OBD2s.

 

Thanks for the heads up and for the dizzy f20b is obd2b car is obd2a hopefully (jr_deleon) is gonna get me strait on that.
But i had another thought on it do you think i could use the f20b harness if i just extended the whole harness to fit in my car or would that not be wise Thanks again

 

ok think i have the dizzy wiring figured out now i need to know how to hook up IAB, and yes i plan to use the f20b ECU but i am lost again anyone have a link that might help. I have been on google for days with no luck.

Ok I know IAB wires are red/blue and black/yellow. I know my F23a1 does not have this in the harness. So where do i hook it to or what pins in the harness do these wires run to PLEASE HELP

 

Reference the H22 swaps for the chassis - should have your answer
