i think its possible. how much boost you gonna push from that t3/4

 

15psi

 

Shouldn't be a problem. You will need bigger injectors though and a 3 bar map.

 

will pte 650cc injecters be good and just get a gm 3 bar thanks for the help

 

That sounds about right.

 

How are those rods holding up? I havn't really heard to many oppinions about them so I'm interested in knowing.
