Are these hybrid turbo's then Jarkko, or just non-variable. The 1500rpm seems like a low spool up rpm for a big blower. Mine seems to spool around 1500rpm as well, and seems like its on full boost by around 2200rpm or so.

How will they mate in with the manifold and exhaust you have at the moment? And also the oil feed, does it all work the same on these turbo's as it does on the stock one?

What are you going to do regarding the wing-mounted intercooler? Surely if you're upping the boost, you'll need a big FMIC?
