JDM F20A block with JDM F22B head

[Fuzzymanbush]

I have to do the timing on my car but I am a little confused I have a JDM F20A block with theJDM F20B head and don't know what timing belt to use any one help me please? DOHC

Your title says that you have an F22B head, but your post says that you have an F20B head. Which is it? They are very different.

If you have an F22B DOHC head, then it seems that you simply have an F20A DOHC engine, unless you swapped the head yourself. In any case, both the F20A DOHC and the F22B DOHC use the PT2 timing belt. Unfortunately, this timing belt is not readily available here in the United States, as no engine here ever came with it. There is one importer that can get the timing belt, but their name eludes me presently. Otherwise, your only option is to swap over to a full H23A1 timing setup with cam gears, lower timing gear, water pump, and timing belt.

F22b sorry half asleep when i posted and the guy i bought the car from said it had the H23a1 non vtec belt so would that mean he did the H23a1 timing swap?

[Jarrett]

I have no way to know. It doesn't fit on there without swapping components, but I also don't know anything about this guy or this car. You're just going to have to see what's on there.

K thanks and why cant i put attachments up?

All h23 products are stamped p14. Look at the cam gears. If they say p14 then it's h23. All Jdm f22b dohc products are stamped p2t

You can't post attachments because bandwidth is expensive, and you're not the one paying the bills.

The F20A and F22B DOHC both use the same timing belt: 14400-PT2-004 (Not P22, not P2T.)

In fact, they both use the same 12100-PT2-010 head. Therefore, you really just have an F20A. If an H23A1 belt was used, damage may have been done. In fact, damage is likely, as the H23A1 belt has 127 teeth, wheras the correct PT2 belt has 126. One additional tooth makes a BIG difference... and on an interference engine such as yours, that means major internal damage. Unless, of course, H23A1 geared parts were used... and unless you feel like digging up specs and examining what you have, the only person that can tell you what you have is the previous owner. I suggest you call him.

I fat-fingered that one. It's been changed.

[deevergote]

It's all good. You corrected my misinfo on Facebook earlier

[djcaz_aom]

As long as the crank gear and cam pulleys match, it doesn't matter how many teeth are on the belt. More teeth on the belt just means the belt takes longer to complete a rotation.

Tooth count is important on the timing gears. That's why you use matching crank and cam gears.

Hope that clarifies timing issues.

Pt2

Pt2 is what it says on the cam gears some one should contact me on facebook it would be easier to reply Jallil Fernandez pic has me with long hair and my gf next to me? or my IG cb7_k20dream

[Fuzzymanbush]

What more do you need? I answered your question pretty damn thoroughly.


The H23A1 and F22B both use the same 14211-PT2-003 cam gears, actually.

You forgot to add pictures.
