I searched but had no luck comming up with much. What has to be done to get the larger journal h2a4 crank in a h22a1? Is it even worth it strengh wise for a full race turbo motor pushing major power? Just trying to research before I start to build my track car.

 

wont fit. the crank mains on the a4 are larger. stop being cheap and buy a whole h22a4

 

yeah wither have to go complete a1 or a4 bottom...i had the same prob..it wount fit..ipickedup acrank for 125 shipped

 

its called line bored,just have a good machine
shop do it and you'll be fine.

 

Cool, Thanks for all the replys
