jdm f22b valves

[bigbozz24]

So according to my f22b specs is similar to the usdm h23 so I was wondering if the valves will fit ?and if not what valves should I use since is so hard to get OEM parts for it? Thank yall

Lots of info here. Its helping me with my build.

How does a thread about the F20B help with a question about the F22B? They're two VERY different engines.


This is one reason why I stick to engines that were sold in the US. When you need parts specific to the JDM models, you're kinda screwed!

I don't know if H23 valves would work, nor do I know how to find out short of comparing them side by side.
It might be easier to attempt to contact a Honda dealer in Japan and see if you can order some. Shipping shouldn't be TOO bad, seeing as they're quite light.

same heads

[deevergote]

Have you worked with both? I've heard differently.
In fact, I believe the combustion chamber size is larger on the H23A1...

[drew12000]

My mistake. Thought i read f20.

so?

[deevergote]

So? Larger combustion chamber = not the same head.

hes asking about the valves.

H23a1 valves work, same part #
I know because ive dealt with them on my setup. Hope it helps

Aight so I'm going with h23 valves on my f22b . Can anyone tell me of a not so expensive but good performance valves to help my hp ??

Valves don't really add much hp; they can help raise compression, which will give you a little extra, but not much. If you're going turbo you don't want to raise the compression any higher than it is already at 9.3:1. They can however make your moving parts lighter for weight savings. Stronger valves can support a higher revving motor.

You also contradicted yourself when you said "not so expensive" and "good performance valves"; if you want the good stuff, you gotta pay.

Race Engineering has valves for $224

Supertech has valves for $285

Yes, he's asking about the valves, but you said the heads were the same. They are not.

Does Honda have the same part numbers internationally? The H23A1 is a North American engine, and was not offered in Japan. The F22B is a Japanese engine, and was not offered in North America. To my knowledge, the two engines were never sold parallel to each other in the same market (especially since they both sat in the engine bay of the mid-level Prelude.)



bigbozz24, performance valves aren't going to do much for you if you're not doing a serious build. Either way, the only thing you can really do is get valves with no dome to slightly increase compression. You'll see far more performance out of a good valve job (and even that will be fairly minimal, but an integral part of good headwork.)

Supertech has a very good reputation for quality. If you want to get something other than stock, and H23 valves will indeed work, then that's what I would go with.

No.
Your part numbers you guys seem to use are different from the japanese numbers we use. (From every case I've seen on here anyway)



Simple example.
Anyone care to post the US numbers for these parts?

Our oil filter part number is - 15400-RAF-T01
And our sump plug number is - 94109-14000

Edit, Just checked:

Valves for 92 H23 Prelude
Intake - 14711-PT2-000
Exhaust - 14721-PT2-000

The reason I'm asking about my valves is cuz in cold start they tap like crazy but then quiets down. So I adjusted them according to the #s that I got from here but they still tap like crazy.so on cold start my motor sounds like crap so I was told to adjust them tighter or to check the valve components to see any worn in them due to be driven with loose valves for a while so I'm just trying to figure out what to do cuz I'm tired of dumping $$.trying to lower the roughness on cold start!!
