i am looking at fitting turbo kit to my h22a vtec but wanted to run standard internals... how much psi could i run to be safe?

also is it possible to run standard ecu or would i need a different ecu if running boost?

 

Hondata s100 or s300 for your fuel management


and no more than 8psi with a good tune.... or you will crack a sleeve.....

 

a sleeve? you mean piston?

 

it depends on the tune.. ive seen 14psi on a stock block

 

There are tons of this on the H22 Turbocharged engine via searching the archives. You'll be surprised in what you find.
