The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

      No, I'm just using stock F23A1 rods with new bolts. I'm not terribly thrilled at this prospect, but it's better than something going wrong at the machine shop with F20B rods. I still feel like a capable machine shop should not balk at widening a crankshaft journal and recreating a radius. Bu, I'm no machinist and I can't make them do it. I'll still have a decent 2.3-liter stroker with high compression and a nice head. I'll be using my Type S/Euro R camshafts for now, but may upgrade in the future. Truthfully, I'm not overly concerned with going wild on this one because it isn't my primary build. But some decent power would be nice.

        Do the F23s use the same 9mm bolt as the F22's? if so ARP gsr rod bolts will work.

        And yeah you'd figure they could, but as you im no machinest.

          The F23A1 uses a proprietary rod bolt shared only by the K20A3. It is smaller and has a finer thread pitch. ARP made a limited run of them for a group buy a few years ago but those are impossible to find now. To get them again would cost hundreds. The PRB pistons weigh less than the PAA F23A1 pistons so I'll be straining the bolts less than typical if I stay within the factory F23A1 rev range. Honestly, I don't really drive fast ever so it's very likely this thing will only see over 6000 RPM only a handful of times. After I rebuilt the F22A that's in my Accord now I only took it over 4000 RPM once to verify that IABs were working. They're fun to build but I don't confuse these cars with something fast.

I also currently have a Prelude VTEC 90 amp alternator that has an extra rib on the pulley. This means I should either use my H22A crankshaft pulley which is slightly heavier than the one found on the F22A, or the one on the F23A. It has the same extra row for the compressor and alternator but Honda put it on a diet. I guess we'll see. I'm not even close to that point yet, though.
            RC17S is in the CB7 and RC17D is in DC5 Also a good deal of RC17S have 4 rows on the pulley, I own one myself.

            I would use the F23A crank pulley if it were me but you may be going for extra rotational mass.

              You're right, I got them mixed up. And I am going with the F23 pulley. Before I install it I'll weigh both it and the F22A pulley to see what the difference is. It could be a pretty easy mod for people. Every '98-'02 Accord you see in the junkyards has the engine partially dropped because someone's already taken the automatic transmission so the pulley is easy to get to.

                So are you using the compressor from the DC5, the RC17D? If so you have to swap the back plate with the one from your CB7 to make it compatible with your EX freon plumbing.

                I never noticed that at the yards about the '98-'02 accords not having A/T, guess I'm not paying close enough attention.

                  i have a couple of Qs

                  as far as i know the aluminum part of the girdle of the f23 only fits the f23, it uses about 10-12 10mm bolts

                  changing the girdle of a block w/o line boring the surfaces will lead o
                  to misalingment of block and girdle bores

                  i know you're set on the f20b head, but you cant ignore the smaller valves

                  why dont you use thw f20b/h23v/euror crank pulley
                  you keeping ps?

                    The main caps separate from the girdle so they'll still be mated to the same surface they originally were.

                    And even though all of the bolt holes won't be filled in the girdle, all of the bolt holes in the block will. So no less attachment will be made between this girdle and the block than what was there with the F20B girdle.

                    I'm not ignoring the smaller valves. In fact, I have a spare H22A head I'm thinking about nabbing the valves from for the F20B head. Low end power is more of the focus here than high RPM breathing, though. Not to say your point isn't valid for my purposes, only that I may choose to spend that money on my main build instead of this one.

                    I will have power steering in every vehicle I own over 2500 pounds from this point forward. I had no power steering on my previous Accord back in high school and it just doesn't suit me these days. So I sold the single-row pulley I had.

                      are you planning on line boring the mains?
                      if not i dont think swaping girdles is a.good idea
                      i can tell you this from experience

                        I'm not. It's an option that I've been given a price on by the machine shop ($120) but with the ability to use the exact same main caps that were on it before, and the flexibility of getting the exact bearing clearances I need from Honda's offerings it doesn't seem prudent.

                        What exactly were the issues you had?

                        And sorry for not having pictures up yet. This has been a busy week at work and I just had a chance to go by there today. I called to ask if I could come get it at 4:00 and he said I could. I get there at 4:10 and he's walking out the door and doesn't want to go back inside. I'm going back home for a few days so it will have to be a next Monday thing at this point.

                          overlapping of the caps

                          dont think the.maincaps of the f23 are stronger, because they're not
                          worry mainly on rod clearences
                          you dont have.to worry about the mains as long clearences are met
                          keep block's caps and you should be good

                              I'm confused. I'm not using the F23A caps. I'm usin the F23A girdle from which the caps are separated. The F20B caps are what I'm using to match the F20B block.

                              It's funny that you say this now. It's sitting in my passenger seat of my work truck wrapped in plastic. I just picked it up this morning. Pictures will be up tonight.
