    the head is also a lot easier to come by in case you blow it up or drop a valve.

          requesting flow numbers between stock and modified f22a head


          how is putting an h22 head on an f22 block unreliable? If your not an idiot and you do things right, you wont have a problem.

            I have yet to see flow numbers for the stock head, but I've heard from both Bisimoto and HondaFan81 (who relayed information from his porter about the F22A's ability to flow... the guy was actually surprised by it!)

            Stock vs. modified would be a good thing to have on hand, though!


            As for being unreliable... it's the person doing the work that is the biggest factor. If you're on here asking how to do it, you probably don't have what it takes to do it right. If you are familiar enough with engine building to figure it out on your own, while asking questions about certain details, THEN you might be able to make it work.

            Still, the amount of effort, and potential reliability issues (for whatever reason) really isn't justified by the amount of power that comes from the swap. Many people say "oh, the H22 has FRM sleeves, and FRM sleeves are bad!", which is their reason for swapping to an iron sleeved block... but that's idiotic. FRM sleeves are very strong, and if you want to put forged pistons into a stock-sleeved block (why, I would never know...) then there are options.

            The only reason to do this is to be different. And it's not all that different anymore.

              there are flow numbers for the f22 head, im pretty sure cisco has them...

              FRM sleeves are good but with high mileage they can wear pretty bad and the fact that you can only go .010 over is kinda crap. plus, more expensive to machine and you need to find a shop that will touch it.

                If you're going to run forged internals, why not just sleeve the block? Another $1000... yes... but still. Worth it to do it RIGHT!

                  because if you're only putting 300hp you dont need sleeves. use that 1k on a blockguard and good tune + meth injection.

                    Well the only thing that lets the h22 rev so high is that it comes with duel springs stock. The f22 is just a single spring on the valve train. If your going to want to rev (which i assume you will because your using a turbo) than your going to want to upgrade your valve train to a double (if not a triple) spring set up, with some sodium filled (or better) valves. Upgrade your valve guides as well. Do some research on building up a head. Having a built up head will be less of a "head" ache in the end. Bottom end work is important but so is top end.
                    Most everything you stated is wrong. The reason why the h22 can rev higher is because, most notably, is the shorter stroke. the cams are also designed to have a powerband in the higher operating range. it has very little to do with the valve springs. A single spring upgrade for the f22 is more than enough. the head is single spring in nature and a double spring is not nessassary when upgrading to a boosted setup. and a triple valvespring setup?! come on now. And sodium filled valves are unessassary as well.

                    Porting yourself will never net the same results you think you are going to get.

                    The f22a head will support 475hp BONE STOCK!!(bisimoto valve springs only mod) I have tested and proved this myself on my own setup and found that the limitations on a boosted setup are more cam related due to crappy overlap on the OEM cam profile which essentially allowed any boost pressure over 21psi to flow through the head and not build any further.

                      475hp is more than most people would EVER need on a street car. That's beyond the limit of reliable FWD traction.

                        we're not talking about traction right now, we're talking about cylinder heads and power.

                          Right. But when you can make 475hp with the stock F22A head, there's no need to do anything else (for anything but looks). You'll have a hard time using that 475hp, let alone more, if it's available.

                          If you want a dyno queen, and you can make more with a headswap, go for it... However, most people intend to drive the car that the engine is in... making my comment valid.

                            Good info. Dee you trust Bisi? I'm seriously considering buring parts from them with tax money to get this motor done! Another question, I have the crank from my F22, would that support the horse I'm looking to run?? Or should I do all new?

                              if you can have someone magnaflux the crank, that would be ideal. bisimoto is reputable, ive bought valve springs from him.

                                The F22 crank is quite strong. It should hold up to quite a bit of power. Of all the moving parts in a Honda engine, the crank is usually the least likely to break.
