Thanks Seb, but ^^thats what the tricky side of it is: people think adding a 'small turbo' gives only a little more hp, so its probably not so hard on the engine...
However, thats where you would go wrong! The smaller the turbo, the larger the exhaust restriction, the higher the Back Pressure in the exhaust, the higher your exhaust gas temperatures, the sooner you have knock and temperature related exhaust valve and valve seat problems.
IF your adding a turbo, use a large one with respect to your engine size and more specifically: also one with a relatively large turbine wheel compared to the compressor wheel.
Thats what I love about the Borg-Warners: their compressor-turbine wheel ratio is larger towards the turbine side compared to Garrett turbo's, which lowers back-pressure and increases efficiency.
