F23A Beast Mode On A Budget

Here we take a look at the F23a block, compared to the H22a1, as well as the K20. The F23a architecture shows that it is clearly an "inbetween" motor. Steel main caps, integrated girdle, but not quite as beefy as the K. It is easy to see why the F23a should be your candidate for the next H motor project. I am hoping the new godzilla deck insert for the F23 will help fill the void between stock block H motors and a full sleeve project. Since the F23 has conventional liners it makes the entire build much cheaper and gives you the ability to run a much wider range of pistons than just the 1-2 FRM compatible options there are for H series.

Thanks for putting up this video! I appreciate the sharing of your knowledge. I have an H23a that I am gonna build with stock bottom, once she blows up then I will track down an F23 for more user friendly sleeves. Keep the Hondiction going

F20b with f23 crank and rods and k series pistons. I think it would be a good combo! That’s what I’m wanting to do anyways.

f23a heads share a valve with the j30a1, j30a4/5 are +1mm larger valves (30/35mm) that can be cut into the f23a head with ease. also f23a shares a valve spring with J30a1 so you can use J32A2 valve springs in the f23a head. with j30a4's 35/30mm valves and port work you can hit 300 cfm with ease. Also j30a1/4/5 pistons fit in F23A blocks along with the commonly know k20 pistons fitting. JNA1 hybrid J30 has the best pistons to use with H22 heads being that they are + dome and the valve relifes are the same size. but don't sleep on the F23A head, just use J series Valvetrain in it and port it.

I have a 2002 accord SE FA23 Vtec it's hitting 230K but love it I was interested on modifying the engine completely overhaul, rebuilt Lmk bro I stay in los Angeles 👍

[bassblaster]

Im workin on an F23A1 on an H2B kit for my EF. wondering while i look for a better shell if i wanna keep the F23 stock or do K20 pistons cam and somithing with the intake

My understanding is that most of the f23a variations are very similar.

[uchiha_d]

Ty for this. Good info to know. I’ll never touch any of these as I’m a k person now after my b series days but still great to know.

[evanovski]

is the F girdle interchangeable with the H (I expect not).
Someone needs to manufacture a solid girdle for the H, similar to that if the Golden Eagle for the B-series

[randyp]

hey bro say someone wants to make around 300 hp on a f23a1 block what would be components you would suggest to upgrade to make that manageable and yet still be a daily driver?

[michaelkuskie]

I have kind of a silly question... what intake will fit on an f23a do you have any suggestions? I'm putting 350cc injectors having ecm retuned gonna change cams and gonna go with wiseco k pistons

[TheycallmeRpCratchet]

What kind of rpm will this bottom end take with aftermarket rods and pistons??

[michaelelliott]

j30a1 and j30a4 pistons also work in a f23 block.

[jimmysway]

Been looking at h swap for a while since I snapped the timing belt on my f23. I know the sleeves in the h are weaker but they aren’t many internal build kits for the f series as it is the b/k/d where is everyone finding them??

[troxstarr]

Cant u just swap the f23a gurldle to the h22a

[christopherelrod]

I've been thinking of doing an f23 block with an f22a head. Do you know if I'd need to plug drain ports or modify it in any way? I see people do the swap but they never tell if they did amything

[GVTEC]

Where do i find a deck insert or would i have to make it

[rollthelosingdice]

Was that H22 cylinders honed? Are those FRM sleeves?

[akordaddikt]

For the g build do you need h22 waterpump gear?
