Let me dispel one thing... Do not raise your compression! It will net you very LITTLE power and only hamper your ability to find gas outside of pumping your own barrel of 100+ octane.

Things you should do for an easy 450+ whp:
4.2l or 4.3l stroker with
Stock compression Pistons
Forged rods
Dry sump oiling system or a semi dry system if you want A/C
Built heads with JUN 282 cams
Replace the intake manifold (upper and lower) with one like 1slow370gygh
Run 3" throttle bodies from an 09+ maxima (talk to 1slow370) and a 3" cold intake
Run headers
3" exhaust or Tomei

Tune by Jon @ Z1

Bam 450+whp

This is the route I would go and may end up going with my new Nismo...
