I'm new to Honda, and am in need of advice for a direct replacement engine on a 97' Accord w/ single ohc NON-vtec (F22B2 I think) and auto trans. ~Spark plugs face to rear~

Would like to consider a late model/low mi. take out, but do not know what engines/models would be considered a direct (manifolds out perhaps) replacement.

Also any reliable source (JDM perhaps) information would be greatly appreciated.

Thanx; Tom S. in Tn.

 

Well, the F22B2 would drop right in without any other work. An F22B1, F23A1, F23A5, H22 would all swap in easily, but require some rewiring, possibily converting between OBDI and OBDII. Basically, how much work do you want to put into it?

 

Trying to perform a minimum of work/fabrication for newest replacement I can find.
How far forward does a F22B(2) model year come to? All I can find are 96/97' worse than ours.
Isn't the F22B(1) a vtec? Will OBDII engine harness and ECU hook up to the 97' OBDI chassis?
Would the base F23A1, F23A5, H22 you mention fit this 97' OBDI car using original F22B(2) int./ex. manifolds, wiring etc?
Thanx for replying; Tom S.

 

F22B1 (VTEC) and F22B2 (Non-VTEC) were offered on the 94-97 Accords.

F23A1 (VTEC), F23A4 (ULEV VTEC) and F23A5 (Non-VTEC) were offered on 98-02 Accords.

H22Ax (DOHC VTEC and non-VTEC) were offered in 97-01 Preludes.

I believe your 97 is OBDII (most 96 Accords were OBDII, I think all 97s are). The F23 would be nearly a direct drop-in replacement, but you would need the intake and exhaust manifolds, distributor, computer, and some other stuff. It could also turn into a wiring nightmare, I'm not sure.

The F22B2 would be the easiest, with the F22B1 coming in second and the F23A5 coming in third.

 

h22 was in 92-01 preludes

 

Yes, but the OBDII one was in 97-01 correct?

 

yeah, but who cares about inspection and emissions?

 

Tennessee does.

But not Minnesota

 

Mr.Finch I think you're correct, this 97 Accord is OBDII. Sorry for the confusion.

The 98/02 Accord F23A5 might be better odds to find with adequate service life left. What type of wiring problems come to your mind right off? Major harness incompat between 97'models and later ones? What if I were to salvage complete engine unit with mounts, manifolds, harness, and the ECU that was on the car it came from?

Are there major differences between F Accord engines and H Prelude engines as complete units? Do you know if the harness is compatible between Accord and Prelude.
(seems I can find twice the preludes around in salvage)

Again, thank you very kindly for your help. Tom S. in Tn.

 

If you want be 100% sure it's OBDII, pull the ashtray out and see if there is an OBDII port behind it.

Some wiring issues I can think of:
- Swapping in a VTEC engine: VTEC solenoid must be wired to the computer.
- Connectors must match new computer: comparison of connector pinouts and swapping of wire may be necessary.
- F22 -> F23 swap: IACV must be rewired to work properly. F22 intake manifold has FIT and IAC valves on it, whereas the F23 only has the IACV. It's something like a 2-wire to 3-wire conversion or vice versa.
- Throttle position sensor may need some wiring work.
- Cruise control is mounted in different locations.
- F23A4 ULEV engine has a MAP sensor on the air intake box. I highly suggest staying away from this engine.

H engines make more power, but otherwise are very similar to the F engines. Many parts can be interchanged. Cameron (Live2Rice) has (or had, rather) an H22 swapped into his 97 Accord and would be able to help you with that swap. It's fairly common, but not all that cheap to do.
