i have a 98 block with 55mains if i can remember correctly. and im getting a deal for a f23 accord ulev crank. will the f23 crank fit?

The_Head

yes it will fit.

what rods do i use? h22 or f23?

2fast4u831

you will need the f23 rods and pistons as well.

The_Head

Yep you use the F23 rods & pistons, not sure what compression ratio it is off the top of my head. I think it's really low though, like 8.8:1 but don't quote me.

guess i gotta go talk to some pistons man..... to make some high comp pistons

F23 pistons won't work since the F23 has a smaller bore.

You better talk to the sleeve man too because you can't run forged pistons in a stock H sleeve.

u think type-S pistons will work with f23 rods?

Should, but you'll still have low compression cuz the F23 rods are shorter than the H22's.

lightcrx

if you use h22 pistons you would think it would be like the f22 setup... meaning higher compression?

whats the differance in pin hieght on both pistons? f22?

According to this post I got from another site they are. how much you want for one with shipping.


Well, since I started this a while back in another thread I figured it was about time to finish what I started and make a definitive answer thread for anyone looking for piston, rod, crank and block specs or compression ratios of various H, F or H/F combinations.
Anything anyone wants to add to this thread post up whatever info or specs you have and Ill add it to this original post. I am putting up only what i have personally measured and or quoted direct from the helms manual. I dont want this thread to get cluttered with he said she said specs so Im asking that we limit contributions to first hand spec acquisitions and or helms manual references only. Whatever I have missed or havent measured myself, please feel free to post and contribute. The items i have yet to measure or discover I will leave blank until myself or another member provides the information.
Im going to start by adding a few specs that I can think of off the top of my head now, I will return later tonight and add some more info which will include a few CR calculations.
If I leave something blank and you have the information/specs plase post it up and I will edit this post and ad the new additions to the thread.

Any reason why? I read a few of his informative posts. Good stuff.

The_Head

I'm using Crower F23 Rods with custom CP pistons in my H22 block.

v4lu3s

i severely doubt that an f23 crank/rods and h22 pistons in an h22 block will lead to ANY kind of low compression.....

The_Head

Yea they will, because the F23 pistons are 1 mm smaller than the H22 block bore, so there won't be any compression at all

The_Head

It's obviously not a very good friend of mine

lightcrx

its ok

jdmcg3

almost everything said in this thread is just wrong.

to use a f23 crank in a h22a4 block you must:
mix and match bearings
use custom made h22a4 rods
use any h22 piston of your choose

deeh22bubble

To do the set up dight u need f23 rods and custom h22 pistons if u use regular h22 will work but piston will stick out of the deck 28 thousand im using crower rods and je custom h22 pistons
