some of you may remember me from this post a couple months ago...
https://honda-tech.com/zero...age=1

so for those of you who don't wanna look at that post.... here's the setup that i will be building:
- '92 jdm H22A block
- H23A1 crank
- 0.25 OS Type S pistons
- P&P H22 head
- Crower stage 3 cams
- RM valvetrain
- Euro-r intake manifold
- 68mm Professional Products throttle body

I currently also have an H23 long block that i've torn apart... i still gotta rip the H22 outta my car, but i gotta make a decision first and i need some opinions...

i know that the bare H23 & H22 short blocks are identical... like i said, i've got the H23 block torn apart and my original plan was to throw the H23 crank into my H22 block, but i'm starting to think that it was a stupid idea

i've already got the H23 block torn apart, all i'd have to do is rip the head off my H22 and throw that on (along with all the other little parts that need to go with it too)... i'm just thinking it'll be easier to build with the H23 block, rather than rip apart my H22 considering the bare blocks are identical

so, i guess the only question i have is..... do i really need to use the oil squirters from the H22 block? this is strictly a drag motor and won't ever see the road... gimme your opinions

its only used to cool the crown of the piston.

 

ok... so do you think i need to run them?

 

Which rods will you be using?

 

H23 rods with Type S pistons

 

h23 rods have oiling holes up top that mimic the effect of squirters to some degree

I have done a few H23 Vtec's in my day .... Anyways I would use the oil squirters with OEM rods for extra cooling even with the oiling holes in the top of the rod like mgags7 said I would still use the coolers for added security.

Just a tidbit make sure you balance the entire rotating assembly so you can rev this bottom end worry free. If you have problems getting the squirters to clear with the crank, just slightly bend them to the side enough to clear the H23 crank and your golden. Either way good luck with your project

 

cool, thanks guys!!!

 

Anytime! It's nice to see someones question get answerd and them understand whats been said, again goodluck

 

Oil squirters are heavily debated in drag cars....or atleast were last time I checked. Im not sure over a 12 second or less pass that oil squirters really do much, however I always perfer to run them myself. Some people say it makes no difference either way and actually dont like them in engines that are going to run for long lengths of time because they heat the oil (which you can add an oil cooler to fix...however the oil temps still tend to rise w/ squirters). Other people will even argue that the topside of the piston sees extremely hot temps and that by cooling them from the bottom you cause uneven expansion which leads to ringland failure.
