need to know what dissplacement i will get with 89mm and 90mm bore on an h22. also anyone here running 90mm on the street

 

forgot to add that it will be running 18-20 psi.

 

H22 89mm with stock stroke ~2257cc
H22 90mm with stock stroke ~2308cc

 

If you plan on going turbo, I wouldn't go with anything bigger than a 89mm bore. If something goes wrong I don't think you have any more room to bore and hone.

 

anyone know what the displacement would be with an h23 crank and 89mm? how about an h23 crank and 88mm?

 

CC's =

<u>(.7854)*(bore^2)*(stroke)*(# of cylinders)</u>
1000

Wrong.

<u>(Pi)*(bore/2)^2*(stroke)*(# of cylinders)</u>
1000

85*89cc Motor
<u>3.1416*42.5*42.5*89*4</u>
1000

=

2020cc

 

thanks...with an h23 crank and 89mm bore, its 2364cc's...srt-4 torque yo...

 

Yours is the same formula (just more complicated).

Algebra is your friend.
