run a TD06sh-25g or t67.
I had a soarer on the dyno yesterday (VB on SAU's mate) and it made 270kw on 19 psi (not on my dyno as gate diaphragm was split, we only saw 230 @ 14psi) it had a 8cm TD06s-25G
if it was mine i would fit a t67 10cm, 280-330rwkw easy, stock bottom end will piss it in. Ive used these with great success http://cgi.ebay.com.au/Turbocharger-Mitsub...=item4153621750
