F22B2 block. I want to put a ported and polished VTEC head on it that I bought at an extremely good price. I don't want to change to a H22 engine, at this point I don't see it as being worth the money. I am going turbo in about two months and from everything I have read the lower compression Accord engine is very good for it. At this point I am trying to do everything I can before that. Which brings us back full circle to the head swap and if I am going to have to change out to a F22B1 block or use my existing one.

 

you can turbo fine w/o vtec.

 

I know I can turbo the non-VTEC but I have bought a ported and polished VTEC head that I want to use; the purpose of this thread.

 

The "B2" doesn't denote the block, just the tune of the engine. The Accord LX and EX share the same block, therefore the head should fit exactly. You will need to acquire some extra wiring and such from an EX to make he VTEC work. Other than that, it should be a very straightforward operation...I think.

BTW, doesn't the H23 have 220hp? Or am I mistaken?

 

the only difference I can find is the placement of the oil control orifice. On the VTEC it is on the head while the non-VTEC is located on the block when you remove the head. If the blocks are all the same why would Honda go to all the trouble to stamp them differently? What would be their advantage. I know the SOHC VTEC is F22B1, the SOHC non-VTEC is F22B2, and the JDM DOHC non-VTEC is F22B. I hope this head change is as easy as it seems. I have procrastinating for about two weeks.

 

wow,this questions has been coming up alot on all the honda boards.

anyways, your better off just buying a F22b1 swap. The cost of a head, ecu, misc parts, plus the pain in the ass install you could buy a full F22b1 swap for about the same price and have a much easier install.

Unless you can do all the work yourself, this kind of head swap is fairly expensive and may not be very reliable when compared to the idea of you taking the vtec head and slapping it onto the EX block. Unfortunately, this means some of your basic mods like the header and exhaust won't/may not be able to be reused which = money lost.

Another thing I'd like to point out. Just because the F22 is low compression doesn't make it a great candidate for FI. The real reason is because the cylinders are stronger than in an H22 making it relatively easier to boost. Even then you should think about resleeving.

The low CR of the F22 really is a moot point bcause if you're going to spend the money for FI (done right) you should be getting forged pistons, new rods and improved valvetrain anyway = pick your own CR.

The advantage of getting the new motor is that you can build it up and mod it without leaving the car in the shop for an inordinate amount of time.
