    I have pretty much everything together now to start putting my turbo on. Because i am going to be installing everything in stages i want to know if it would cause any problems if i was to install the forged low comp pistons before i put boost into the engine? i know the compression ratio would be affected, would this just cause a little less performance until i have the turbo plumbed in?

    Cheers

    I don't think you'll loose a fat lot of performance actually, I'm pretty sure its safe to lower compression without turboing

    even if you were to loose 10% that still leaves you with a healthy 108bhp (assuming vts)

    Just a question. How do you plum in a dump valve?

    mine actually attaches directly onto the side of the turbo charger but most go anywhere along the turbo hosing. You make a T junction in the host and attach the dump valve. There is then a valve on the top which you attach to the vacumm pipe on the engine side of the intake so when you close the throtle a vacumm is created which pulls a diaphram and spring upwards in the dump valve which releases the compressed air. Sorry if that didnt make sense. Its early.
