Hi, I have one of the M30 cartech twin manifolds. I am interested in using T25s for better price and faster spooling. I have just started researching and have seen T25s meant for honda civics go for pretty cheap. At 20psi, can I get 500hp with these on my 3.5L or will they poop out before redline? I think the 265 tranny won't take more than 525hp. Any recommendations on compressor/turbine wheel sizes? Would it help the low end power to make one turbo smaller and the other big for top end?

Thanks!
