Best turbo to use is a cos turbo, do not get a t34 unless you want over 300bhp it's over kill and too laggy, the car would be quicker with a stage3 t3 running flat out with 30/40bhp less
Cut back blades slow down response too, when I researched it every tuner I spoke to said run a 2wd cosworth turbo rebuilt with 360 bearings and would flow a genuine 270bhp and be a lot more responsive than a stage 3 t3
Plus it may say on the net that a stage3 t3 will flow 280bhp but in over 10years of being in the ford scene I've never seen a 1600cvh get near it with one fitted, only ever on a zetec turbo
They make more like 250/ 260 at a push and isn't as responsive as a standard 2wd t3
I got a mint 4x4 t3 for £150 for my zt
