K24 crank in a H22A4?

[quickangel93]

you are 1.5mm below the deck still, since h23's are 30.5 not 30mm. you need 139.5mm rods to be even. or h22 pistons at 31mm and 139mm rods.

are the mains and journals the same for both? h22a4 and k24? also what about BE diam for the rod?

what about b18 pistons?

[GhostAccord]

how about

H22A block = 219.5mm deck height
K24A4 Crank = 99mm stroke
H23 Pistons = 87mm bore ,30.5mm compression height
K20 Rods = 138mm rods
You would end up with approx. what?

Using a USDM H23A1 with a -10cc dish piston. You would end up with approx. 8.6:1 CR

Using a JDM H23A = with a 0.00cc (Flat Top) Piston you would end up with approx. 9.8:1 CR

i changed the info, you are really at 1.5mm, but if you change to h22 pistons you will be at 1mm below the deck, using the rsx rods. but still will a k24 crank even work?

it will work. someone did it already, i know we have to cut the mains.

yeah but a jdm h22 pistons around 1.9cc would give him close to 12.4 mmmm yummy. and he would be closer to the deck.

the first one is only :2 smaller than f22s which is 8:8

i hope you dont mean 12:3 cr

[bagoon316]

no 11.7:1 CR.

why you goin N/A or boost?

EDIT: i am fuckin up all my shit lol.

[quickangel93]

no 12.4:1 CR.

boost, im not going n/a

[bagoon316]

i also have 9.8:1 instead of 8.6:1 with regular h23 usdm pistons.

Closer to 9.8:1 with USDM
Closer to 11.3:1 with JDM

[trah]

just after your all said and done clay the motor. ALWAYS CLAY or you'll be ***! good luck man

[quickangel93]

Closer to 9.8:1 with USDM
Closer to 11.3:1 with JDM

what calculator are you using?

99mm stroke + 30mm compression height = 129. 219.5mm deck - 129mm = 90.5mm left

[quickangel93]

ok using

h23 pistons - 30.5mm
b18 rods - 138mm
k24 crank - 99mm stroke

put it in the calculator and see what you come up with

What CC do you have the two different H23 pistons listed at? I have them listed as follows
H23A1 = -10.5cc dish top piston and
H23A (DOHC VTEC JDM Accord SiR) = 0.00cc or flat top piston.

8.6:1 for the H23A1 and 9.8:1 for the H23A

They are two different engines/pistons just like the JDM H22A and USDM H22A1 have two different compression ratios.

ok using

h23 pistons - 30.5mm
b18 rods - 138mm
k24 crank - 99mm stroke

put it in the calculator and see what you come up with

B18 rods will need to be machined as the BE width is too thick. And they are also 1mm to short.. you need 139mm rods to fill the 219.5 H22 deck height. or 31.5mm Compression height pistons
