    220whp is a little unrealisitic on this build. you'd probably be making about the same power as a relatively stock H22A but spending a ton more.

      The F22B head is about 3ccs larger chamber than the F22A. If everything is left stock on the headswap the F22A's 8.8:1 drops to 8.4:1 with similar cams. If you think about it the H23A1 is virtually the same thing as the F22B. It's got another point of compression and 100ccs more displacement and they typically dyno less than 150whp in I/H/E trim. With less compression and less displacement you'll be hard pressed to make as much or more power even with cams.

      With 2.3 liter displacement, high compression, ported head, bigger cams and high-end free-flowing exhaust 210whp is possible but at what cost? For a similar investment you can make a lot more power with a VTEC head. Also with large cams on nonVTEC platforms you start sacrificing driveability.

      Dollar for dollar VTEC will yeild more power once you start investing in all the expensive components.
      VTEC G27? = ???whp ???wtq
      VTEC G23 = 220whp 191wtq
      nonVTEC G23 = 200whp 183wtq
      K24 iVTEC hybrid = 260whp 210wtq

        Ok so the f22b head swap is out. So im pretty much left with the h23 frankenstein or h22 swap. I figured these would be my final choices but it doesn't hurt to try lol. I know the h22 is the better choice in terms of reliability but the h23 frank would make more power easier right? So what are some pros and cons on the h23 frankenstein? How reliable is it really? And would I save any money going this route?

          if you want to hit 220 with out a bunch of problems......boost.

          and it cheaper

            As in problems do you mean it'll be more reliable to have a 220whp turbo f22 than a 220whp n/a h23 frank or h22? Because from what I know n/a is more reliable especially with an h22 all it takes is a set of bolt-ons, cams, and a good tune to get @least 200whp+

              trying to push a N/A f block to 220.

              and you'll only get to 220 hp with a stock H block and some bolts on's is if it's a JDM type-R (or is it a type-S).

                u would have to do a lot of work
                cams
                valves / springs
                I/H/E
                high comp pistons
                etc

                but 200+ on a f block isnt impossible. bisi biult a f22a1 to 350 hp for the top shop challenge. it was the slowest engine but the only na one and the most reliable one too

                  I didnt say stock h22, i said cams with bolt-ons and a decent tune will get you 200+whp. This would be alot more reliable than a stock f22 with a dsm setup from what i know. N/A is always the most reliable route when it comes to honda engines. But my question is how reliable would a h23 frankenstein be? I hear its more reliable than an ls or b20/vtec. What parts would I need to accomplish this build?

                    A turbo setup at only 200hp not reliable? i disagree, I've NEVER seen or heard of anyone blowing a stock Honda engine at only 200hp (ghetto setups with no tune don't count)

                    There is nothing wrong with a nice N/A setup, but the reliability is good either way.

                      Ok cool but what I'm saying is if i went boost im going to be aiming for 300-400whp @least but only about 220-250whp n/a but I guess I just stuck trying to decide the choice in terms of reliabilty and funds. For example:

                      Turbo setup:

                      Block:f22a
                      -h22 forged rods
                      -wiseco 85mm evo stroker psitons

                      Head:f22a
                      -delta 272 cam
                      -obx cam gear
                      -supertech valve springs, retainers
                      -valves???
                      -street aggressive pnp

                      ebay fmic
                      obx wastegate
                      obx blow-off valve
                      obx turbo header
                      obx downpipe
                      aem fpr
                      aem fuel rail
                      walbro fuel pump
                      dsm/rc 440/560cc injectors
                      megan racing drift spec 2.5in exhaust
                      h23 tb and im

                      Ecu: apexi vafc or hondata s200

                      How reliable will I be with this setup? Keep in mind this is a daily driver lol as daily as it gets. I drive my car every single day. I'll be driving this at about 220-250whp daily but 300-400whp when I need it.


                      N/A Setup:

                      Block:H22a
                      -type s pistons or mahle 12.5 pistons (if i can find them)
                      -h22 forged rods

                      Head:H22a
                      -stage 2/3 skunk2/crower cams
                      -skunk2/aem/obx cam gear
                      -ferrea valves
                      -supertech valve springs,retainers
                      -street aggressive pnp

                      smsp tri-y header
                      skunk2/euro r manifold
                      aem cold air intake
                      megan 2.5in drift spec exhaust
                      walbro fuel pump
                      aem fpr

                        please explain...I don't see how dohc alone raises hp.

                        Now I know the h22a and other DOHC engines have higher compression than their SOHC variants...that is the actual main setback and reason why they have higher power...in addition to other things like stroke, intake design, exhaust design...but compression alone is a major factor.

                          this is a invalid statement lodollar and many others have proved that their set up can last just as long if not longer then n/a hell my last motor before i took it out ran for 2-3 years and i only took it out because i am building the f22b and need to prep the engine bay for paint.

                            all comes down to the knowledge/experience of the tuner AND builder

                                Ok guys thanks for all youre imput I've pretty much decided to boost the f22 I'll probably just boost on the stock block for now with a 220-250whp goal and later rebuild the block. With that setup listed above without the built block could I reach my goal on 7-8psi?
