My VG30DETT Modifications:

Jim Wolf ECU w/ twin POP
555cc injectors
Greddy Profec B boost controller
Custom intake 
Dual 2.5" into single 3.5" exhaust, no cats

Boost setting is 15PSI

ZXTT guys would call this a "Stage V+" level of modification.

By all accounts this setup should produce something over 300 wheel HP (that's 370hp for those comparing output to what a manufacturer like say, Chevy rates their Corvette's at..). With the car weighing at around 2600lbs, it should move pretty well. Of course only driving it will tell the story if it really works or not.

Stage III is claimed to put 396hp to the crank, with stage V being in the 415hp range. I'm a pessimist, however if I can get to 330 wheel HP (400 crank) I'll be happy....for a while... :-)
