I want to upgrade the stock turbo on my rb20 det. I have to motor in a 1983 mitsubishi sigma , got the motor from a r23 gtst skyline. i was consedering upgrading to the vg30 det turbo, from the 300zx, the single turbo( ball bearing )300zx, not the twin turbo 300zx.
these are the details and modifications done so far:
stock engine internals
18"x12"x3" front mounted intercooler
2.5" intercooler piping
3"free flow exhaust
IS300 Apexi N1 Exhaust
5frd manual gear box (rebuilt)
exedy street and strip clutch
ecu flashed
mitsubishi sigma 2000 rear end (diff) 4-1 ratio but soon to change to a r32 rear end
iridium spark plugs #9
walbro external fuel pump.
cost is a factor, that is why i am thinking of the vg 30 turbo,
so any help or advice, thanks
