d15b7racer

I have the greddy soch turbo kit on my 94 dx motor and have a few questions. first how much boost can my d16b7 engine handle? its like **** tuned but i was wondering if i could maybe make one 10 psi pass at tracks or would one time be too much already? i'm only running check valves and fmu (no blue box). secondly with keeping the greddy manifold whats my choices on upgraded turbos? i'm really guessing none but does anybody know? i currently have the TD04H 14b.
