Turbo pistons into a non turbo HR3?

[barry100]

Hi All
I've got some good standard  turbo pistons from a HR6S, I need 3 standard pistons for a HR3, any idea how they would perform? the combustion chamber is the same volume but of a more open design, revs of the HR3 is 1500rpm, the HR6S and HR3  share the same cylinders and heads

From a materials and durability point of view they will probably be better then the NA version. However , with the combustion chamber being a different design I suspect that may cause problems as injectors and chambers are designed & developed very closely together.
