Yeah I'm also interested in where you got the sump mount poly from

Did you see my reply in your 'Part Number' thread?

Engine looks nice!

But at 3.5krpm and 15psi both engines will be the same or the small turbo will be better due to spooling faster, same container volume same pressure so you will only yeild more power by going for more revs which is engine N/A or turbo 101. Making more power with higher revs always needs a bigger turbo so saying a bigger turbo gives more power because it gives more air at a lower boost is rubbish, it gives more air at higher rpms at lower boost or the same air at the same rpms and the same boost.

Tremendous build!, just stumbled on this courtesy of a link drew posted on another forum
one wee thing, i think one of your radiator fans is the wrong way around..




thats a bit nieve mate. a bigger turbo will allow an engine to make more power at the same boost at the same rpm level, this is because the turbine is free-er flowing, and more efficient on boost at turning exhaust gas energy into mechanical energy to power the compressor. the more efficient you extract power from the exhaust, the more free flowing the exhaust becomes, the better cylinder filling becomes, the better the VE of the engine becomes, and so you have a thripple whammy affect, more charge in the cylinders, less spent exaust gasses in the cylinders (promiting detonation allowing for a more aggressive tune) and a better flowing exhaust. All of which increase power without increasing boost.

I have tried 3 different sizes of turbine on my k, and the affect is noticeable.


The obvious trade off is the boost threshold moves further up the rpm band which isnt so good for a street car, but a non issue for a race car.

Yeah but it wont give the same boost at the same revs
