cheers
go for a t34.48 minimum
but if you want to stick with a t3, then you dont want to go beyond 26psi peak and 22psi held, unless you like changing turbo's
a t34 is proper stage 3, t34.48 is good turbo for the road, but any bigger exhaust housing than than then your injectors will be the limiting factor if you want to get the most of the turbo
a brilliant all round road engine is, 500 cooler, t34.55 or .63, siemens 55lbs with a chip to suit. i ran t34.55, siemens 55lbs, 500 cooler, msd chip. peak 30 psi, held 27ish, awesome for the road (365hp ish)
edit: if this is going into a 4x4 car with standard MT75 box, then i wouldnt go beyond 350/350 for the sake of the box
