I need some help, I have a 92 lude si that I'm rebuilding, I'm building a h23 vtec, and I need to know if the rods for a h22 are the same size as the rods in a h23, can any body help? I know that the cranks are diff., but the pistons are the same.

the deck height is the same

h22 and h23 rods have the same big end but are different lengths
h22a/a1 pistons are pressed-fit wrist pins
h22a4 pistons are floating pins

becareful using used pistons that have had the pins pressed out. You need to have the pin housing inspected for damage.

Re: engine rebuild

Thanx for the help, umm do you know which rod is longer the h22 or h23, i know the stroke for the h23 is longer so I'm thinking that might be the longer rod. I did research this build, but I'm building it b/c I want vtec and just to say I did it, this my first project car. Ive been asking about the rods and such cuz I chewed up all my rod and main bearings so I figure while i'm down there I will replace the rods, crank, and add the piston squirters from h22. Also any suggestions on a reputable bearing company, I know I'm going to use eagle rods, not sure which crank yet, and either cp pistons or mahle gold series pistons.

Re: engine rebuild

are you going to sleeve the block?

h22 has shorter stroke but longer rod
h23 has more stroke and shorter rod

any bearing is fine as long as it meets the correct clearance. I used ACL.
If you end up running forged pistons, you dont really need the oil squirters. Plus, they will get in the way of the rotating assembly and you have to bend them to clear the pistons unless you get a piston with a short skirt.

all the information you need to put an h23vtec together is on the internet.

Re: engine rebuild

Search button + research FTW. Good luck on your project. There is a wealth of info on this site alone, and an infinite amount on the rest of the net.
