I am getting an h23 within the next few months. I am thinking about using the type s pistons in it. Along with WEBB cams and anywhere from 50-75 shot for the track. Let me know what you guys think.

 

you will melt your motor in a matter of hours....

Type-S pistons in an H23 = 12.3:1 compression

that's enough to melt the motor as is....it will detonate all day...

Add a 50-75 and I'll give you one run before you blow it to pieces..

 

LOL, looks like I may not be going that route, how did you figure out the compression? I've been looking for the info on the type-s pistons and haven't been able to find it. My best guess was about 11.5:1 However that really isn't my field. Anyone have any other recommendations??? Thanks dude.

 

I have a set of 97+ H22A4 pistons for sale, used but only 6k miles on them, make an offer, should increase your compression over 10:1. Make an offer on the pistons

I used the Compression calculator on c-speedracing.com I enterd all the h22a specs....making 11:1 compression by messing with the compression height.

Then I changed the stroke to 95mm, then change the cc volume from 53.8 to 50.

USDM H22A in H23 = 11:1 compression
JDM H22a in H23 = 11.8:1 CR
Type-s in H23 = 12.3:1

I used to have a pic of my buddy's block..he ran type-s in an h23...lasted a couple months till he melted the side of the piston resulting in no compression in the cylinder.

 

Thanks Satan, I've trying to find your calculations for the H22 piston in the H23 block but couldn't find it. Well there you go 11:1 for a H23 is pretty good if you plan on going NA or just daily driver. Let me know, need to sell let me know.

 

Thanks guys. I think for now I'm just gonna use the pistons in it. I will just do the necessary headwork to get the compression up a bit. Thanks again. Oh and by the way, how did your buddy tune the car???

 

Damn those canadians are pretty smart aye.

well he didn't...hence the problem..
