oil change is easy pal, easy to look after turbo engines, i'm running a well powered zetec turbo setup in my xr2, loads can be done to make them pull much better.
i reckon on 350bhp about now and loads to come as soon as i can sort a clutch to hold the torque.
if you get stuck with servicing etc. then i'm only in blackburn close to J5 off the M65.
