As standard they have yellow injectors and a 2BAR map sensor
The "normal" stage 3 conversion which will see 330-350bhp will consist of:
-31 Actuator, Green `803` Injectors, 3BAR Map Sensor, RS500 Style Intercooler, T34 Turbo
Do'nt think I've missed anything on the list for Stage 3, oh, some good brakes

standard 4x4 cossies have blue injectors
other than that def look at the inner wings and the backs of the sills for rust.when/if you drive one look for smoke and if on cold start there is any piston slap(more common on 2wd)
