i got a T78 on mine, bit larger than the T70 im lead to believe
but i get very little lag, boost hits bout 3000rpm. only mods are big wastegate, bov and fuel regulator, oh and new computer.
19 rating 6 first car
R31 silhouette, rb25 with rb30 bottom end, t78 turbo, microtech ecu, wastegate, bov and exhaust along with gauges.
Justcars quoted $1628 full comp, quite happy considering what my car has on it.
chippy will depend on the market and if people build houses or not. where as a sparky is pretty much always in demand, even with that you can do jobs on the side for your mates installing stuff and that in their car. thinking back now wish i did start an apprenticeship but its a bit too late now for me.
but yeh as first year, it'll be a struggle but in the long run, you can start your own buisness and make some good $$$ etc.
