CD5 engine swap

[Shadow91]

So a buddy of mine blew up his f22b2 last week and we are putting in a new engine in it on wednesday.. Now the thing i have questions about is, he is getting an engine out of a 95 EX accord.. so a F22B1 vtec engine...

isnt 95 OBD1 still? its going is his 97 which is OBD2 and all.. I'm curious what everything we have to do to make sure everything works properly in the car and that the engine runs correctly..

He is getting the ECU with the engine.. but again.. OBD1.. not OBD2

Any ideas?

Convert the chassis to OBD1, including 94-95 engine harness and ECU harness. Or convert the OBD1 engine to OBD2, 96-97 F22B1 distributor and us his original oil pump housing with the TDC & CKP sensors. Along with the timing and balance belt drive gears from the crank on the OBD1 F22B1. Then you would also have to add the VTEC wires and run an OBD2 ECU, or an OBD1 ECU with a conversion harness.


No chance on him getting a 96-97 F22B1 and ECU?

I tried and tried to convince him to get a 96/97 engine.. Told him i have the hookup at a very reliable junkyard and he still just bought an engine off of craigslist.. But he already bought the stupid engine and now were are kinda in a spot that i've never done before..

I guess he did NOT get the ECU so i'm sure that thats going to make more of an issue...

But let me get this straight..

-Change Oil Pump from the B2 (non-vtec) block and put on the B1(vtec) block so we have TDC and CKP
-Put the Balance and timing pulleys from the B2 to the B1
-Put the distributor from the the B2 block on the B1 block
-convert harness and run wires for vtec to ECU

Then it should run?

Thanks a billion

My 97 Accord is OBD2, but it has OBD1 style plugs for the distributor and injector. I'd run it OBD1 personally, that's what I'm going to be doing with my H22, using an OBD2-1 conversion harness with OBD1 distributors and injectors, and running the wires for vtec.

[Shadow91]

Yeah. We would need the ECU and complete harness to make it OBD1 correct? As well as making a hybrid harness between the two harnesses?

He just wants/needs reliable transportation right now..

[Shadow91]

Okay, so we have been working on this thing every chance i get, and it still doesnt want to turn over. I have tested everything and it seems like everything is working but the engine is not firing.. I have spark, i have fuel to the rail, but it seems like the injectors dont want to fire...

Rereading this i realized that we didnt switch over the pulleys, is that going to make it not fire at all? is there a mark on the timing/balance belt pulleys that is screwing us right now?

Also, will the engine run okay without the vtec wired in? We havent had a chance to get that all plugged in correctly, as well as the proper ECU. We just need to get this bastard running..

you know, it's illegal to put an older motor into a newer car. later.

You haven't told us what ECU you ultimately went with either. If you're using an OBD2 ECU then you need to have the OBD2 oil pump installed with the crankshaft positioning sensor. Unless you're converting everything to OBD1 that has to be done.

[Shadow91]

I'm sorry, we have the stock ECU in the car, so the OBD2 ECU, and will eventually get the vtec OBD2 ECU..

I have the OBD2 Dizi, the OBD2 Injectors, and the OBD2 oil pump

I did not know that.. Why is that?

[GhostAccord]

Isn't that a state/provincial law or is that across the US?

It's not illegal here where I live in Canada!

[Shadow91]

Eh yeah, its frowned upon because of emissions.. But the engine is damn near the same as a 97 F22B2.. I dont think anyone can just look under your hood and know that you have a 95 F22 not a 97 F22.. Kinda dumb.. haha

So Thursday im going to switch the crank/balance pulleys.. Hopefully itll start up then..

Also, will it run okay without vtec wired??

[Accrdwgnguy]

I bet its the computer needs to be re-programmed due to security issues. Have you tried plugging in the original ECU from the car?

[Shadow91]

Never unplugged it?
