enginehead

Hey everyone. I am new to the site and looking for some help. I have been searching the internet and have found some information but nothing specific. I know what parts I need but it is the assembly that has me a little puzzled. I am wondering about timing the engine with the F23 block and H22 head. I have an H22 crank gear and working on the water pump gear. what I am wondering about is timing the engine.
1) I have read I need piston 1 at TDC, but am not sure how to line up the crank gear, do I use the factory key way and just put the belt on not caring where the timing mark is?
2) how does the H22 crank gear work with the factory crank position sensors?


I have been looking for a copy of the Import Tuning issue with the article about this. I am also disappointed but understand why Piston took his write up down.

Ghost accord and pirate mc fred are 2 people that come to mind who I think have built these and can prob answer your questions.

I saw pirate mc took down his write up for the G23 he built. I think he was mad about doing the research and then other people building and selling them.

I think you are new to any swap or engine built. First you should take the honda manuals for both engine and see how to set timing on both.

As both blocks should be the same height, the steps to follow shall be the h22.

Questions like what tensioner, or what timing belt, or how to set timing properly are ok. But "how to set piston 1 at TDC", that's too basic to be asking.

Do you actually are building the swap, or planning to do it? I never use the timing marks on the crank gear, but if I am not wrong, I think h22 doesn't have one. The timing mark on h22 I think is at flywheel.

Don't take it bad, but you should start with a prelude repair manual.

Also you are on the wrong forum. This shall be on hybrid swap.

as you can see from the gear there are timing marks on the crank gear. I was wondering more about the key way on the gear, does it match the F23 crank key way for lining up with cylinder 1 at TDC


the other think I am wondering about is the crankshaft position markers on the gear, do they match the F23 gear positions. I don't have my F23 apart cause I am still driving the car, that is why I am asking

Keep f23 gear. Make it ob1 with a p28 and an obd1 h22 distributor. Use a screw driver through sparkplug hole to set piston 1 at TDC.

I think the F23 gear might be the wrong size, from what I understand the crank gear needs to be half the size of the cam gears to get them to turn at the correct speed.
I am planning on assembling it with the head off so I will be able to find TDC with a dial indicator and timing wheel. I still do not understand why the aftermarket does not support reprogramming Honda OBD2 engine modules, is it cause no one has taken the time? someone had to invest the time to do it to the OBD1 modules, wouldn't it make more sense to do it to the OBD2, better modules and control right? what do they do to tune the K20/K24 engines, do they make those OBD2?

What I said before, you keep the same "from what I understand". Get the prelude manual.

After assembly everything, you will to set the TDC. The easiest way is through the spark plug hole, and if want to go extremely accurate use the dial indicator.

When you start dealing with the two cams for the first time, moving out of place, you will know the good of it. So find a friend that can help you with.

And honestly get a manual.

And about the ECU stuff, they are different, and maybe someone do it for obd2. Just obd1 is easier, don't have to deal with crank sensor, secondary O2, etc. It doesn't have or just delete it on program.

That wasn't the issue. It's a matter of intellectual property. The info was provided to the community for free, it's the community's property. The owners of the H-T forum profit from the collective input of the community and then claim it as their property. I do not agree with that. Content I provide is not theirs so I chose to remove the content while I was able to. I do not care if people build hybrids for profit.

Anyway, F/H hybrids are going on 11 years, AKA not new, if you can't find or produce the info yourself then you're not trying very hard.

This is also not the appropriate forum to ask this type of question.

good luck.

OP, At least your thread has something to do with assembling an engine. Its not the usual " my vtech doesn't kick yo, HELP ME", It could also go in the hybrid forum but F it. Since your already here and all...

The thing I'd be concerned about is if the F series and H series cam gears ARE INTERCHANGEABLE, then i think it's safe to say the crank gear is also. Since no matter what the cams will turn half crank speed regardless.

Is that sensor the crank position sensor needed to run the engine? Or is it the crank fluctuation sensor used for misfire detection only (obd2).

PyroProblem

I think most engines crankshafts have the keyway cut at #1 TDC. I can't think of any right now that are not that way.
Always wanted to do one of these builds too.

From what I understand, certain obd2 ecus can be hacked. K series being one of the few.
