As above is this a good upgrade for the classic with a tdo4

 

Yes the TD05 16G is a good upgrade as long as you get the right one but you will need supporting mods and it may eat your clutch, gearbox and brakes, plus the car will need remapping/aftermarket ecu and i'd also look at upgrading your injectors, so all in all it wont be cheap.
