f22a1 head swap

[ldrake66]

I am new to the tuner world and i am wanting to know if i can easily swap the cylinder head on my 93 accord. the head gasket has a leak and i need to change the timing belt and balance shaft belt. while i have this engine torn down i was wondering if i could just loose the f22a1 head and put a different one on that will bump up the power? And if this is possible what other mods will be needed (ecu, ect.)

you can try a jdm f22b, it's a dohc but you're going to need an ecu that'll support the setup. chipped ecu would be the cheapest and most cost effective way to go.

you can also put a cam in it and get a performance valve job done since the head needs to come off anyways. make sure you have it surfaced as well.

Please search around, there's existing information all over the forum.

There are a few options. I would recommend, that if your car is A1, to replace with an A1 head if anything. The troubles you'd go through and little monies spent here and there just to yield an added 5whp is not worth a head swap to a Bx or A6, etc. If all your car needs is an HG, I would just replace that and belts after proper prep and TDC. But again, I have a practical approach. If you want "added" power, and already have bolt-ons, you could switch to H23 IM and plenum, as well as source a Bisi shielding gasket. Any different head, and you'll have to use the correct corresponding ECU.

a6 head and a1 heads are the same

[DJ metadelic]

Besides different cam, head. And windage tray/pickup/cooler, block. etc etc but yes. Same ideas, imo much improved in the A6 vs A1

The HEAD is the same. Those parts that differ are all bolted to the head.


Headswaps on the F22A are not a good idea. You are better off building the F22A head, or swapping in a full engine of a different type.

no

a6 head and a1 heads are the same

No they are not the a6 head has a more aggressive cam and stiffer valve springs for the more aggressive cam then the a1 and a4.

The HEAD is the same. The actual head casting is identical between all the F22A engines (and I believe all the F20A and F18A engines as well...) The parts attached to it are different, yes.

[wed3k]

actually they are different, one is casted with "pt6" and one is "pt3"

I lol'd when I read this. People dont understand what bolted on means. The heads are the same.

I thought they were all cast with PT3.
