i'd like to see a stroked 3s with a PD charger. something nice and different.
turbo gearbox upgrade is easy enough, nor particularly expensive.
may be worth while buying a turbo halfcut then adding a SC, that way you get everything you need for the gearbox etc and you have a low comp motor to run higher boost and the inj's and ecu to cope.
there are many ways to go about it. varying degrees of difficulty and expenditure.
