most rate their turbo at 228 whp @ 8psi
and with more internal work could yeld alot more ....
most are probaly using the same turbo manufactor and then
i guess it's their tuning (fmu) that may differ the most ....
i'm not sure but if you check out jeff's 240sx you'll see that
it's a system that requires more than what is provided in a
kit and although the ka motor has alot of torque ...it's the cost
of it all in the end ....
