We're running 396 @ the rear with Pistons (11:1 compression), Cams, Rods, Heads, Headers, Intake, Improved Fueling, Tune, HFC's and cat back on 91 octane. With 96 and above will crest 400 quite easily. With a bit more tweaking, it will surpass 400 rwhp 91 octane and what's been done to the motor is considered mild in comparison. Price is reasonable and the motor is much more reliable then and FI motor, especially for everyday driving.

The problem with an FI motor, is the eternals. They can't take the pressure and continuous abuse. Parts wear quicker and are very susceptible to breakage, particularly mains, rods and cranks caused by inefficient oiling.

lol i made a thread about this in the engine/FI section of the site. Im building a NA 09 370 nismo engine to "hopefully" the 400whp+ range.

I'm still waiting on the dyno graphs for the said 396whp.

Oh sure they will. Pistons, Cams, heads, headers, intake, exhaust and tune will get you there with hp to spare. It's all matter of how much you want to spend. Forced induction isn't the only way to get over 400 hp. You don't need nitrous or forced induction.
