Oldest trick in the turbo book - which is perfectly ethical business - but does the price warrant the adjustment.

I guess it's trade secret

lol nope, because the stock housing restricts the flow, ive seen it Z guys stuffing gt2560 rotating assemblies on the stock housings loosing on average 50 - 60whp because of the housing alone. on the lower 12psi range.

your doing it wrong- or they are.

seriously it works

some of the best setups I have used and turbos I have sold have been tiny housings with huge inset wheels - it's the machining of the housings as well as proper wheel selection that makes the biggest difference.

Your buddies should send me their turbos...takes a while for turn around though

PS. the Z housings are VERY small for a production turbo and the GT2560 is hardly an upgrade at all if you look at the trim - size comparison - and more importantly the compressor maps of either.
