With the engine beginning to take shape it was time to address the issue of selecting a decent turbo, Turbochargers arent't my strong point knowledge wise so after some help from the very patient people of PF

I decided to opt for a T3.
I managed to source a T3 Turbo from a 4x4 Saff that had not long been rebuilt with a 360 degree baring so had pretty much the same spec and internals as a stage 3 RST T3 so I figured it was a good starting point and keeps things simple.
The Stage 3 T3 with -31 Actuator :
Should suit what I need perfectly!
