Well.. got the aluminium rad. and cts box in for a while now but i'm stil not happy with that turbo....

really want to get some decent boost @ arround 2500 rpm or so.
i've got a stage 3 turbo now ( 0.48 exhaust hausing, cosworth comp. wheel , 360 degr. bearing )
Whould it be better for a quicker spin up to put on a standard turbine and housing ( 0.36 ).
Doesn't have to run silly amounts of boost, arrond 18 psi.
Or just go to all standard Turbo ( for now ) wich spins up quick enough ( so i've heard ) on a ZVH engine.

Thanks
