I'm building my engine and i want install in H23 block with H23 crank Type S pistons and rods. I used search and saw FAQ, but i don't find results.

Anybody has finished this setup ? What CR i have, if i install H22 rods???

 

it would be too high compression for a street motor, in my opinion. thats in the area of 13:1 compression.

 

If youre gonna build a motor why put OEM parts in? just spend a little extra money youll be better off in the long run

 

stock h22 rods on 95mm stroke with the type s will put your pistons ~.080" out of the hole. according to the compression calculator, with that combo, you will be at 15.82:1 comp. Good luck use the h23 rods. Even with those, and a stock thickness headgasket, your cr is about 13:1.

with the extra stroke of the h23, them type s pistons just make crazy compression unless you get a thicker headgasket. in which case you could just as well use base h22 pistons and a stock headgasket.

also i forgot to ask which head you are using.. I'm assuming the h22, but the smaller combustion chamber on the H23 head will put all of these values almost a full number higher

better parts aren't a little exra, they're a lot.. especially if you go forged. With an h23 stroke you can bust out some serious compression with stock FRM compatible h22 pistons.

 

aries forged pistons

which requires sleeving, which he isn't doing

 

Its a funny concept , the more you spend the more you have to spend .

 

also remember that type s pistons have floating wrist pins so that would need to be modded
