Remember these dyno numbers are from an awd car that has this engine so the 400z will dyno a little more. https://www.infinitiq50.org/threads/...thread.124379/
If you dropped $15K on an SS and only got 500-550rwhp, you got shafted. $15K can get you a 2650 blower kit, catless headers, toohighpsi's complete port injection system, and a set of drop in pistons and rods. Sure, you have to turn some wrenches yourself, but we have members here making 900-1000rwhp on their SS with similar set ups.
Hell, I will be looking at 650rwhp+ with a smaller blower kit, 2nd hand LT4 fuel system, flex fuel sensor, cat deletes and a tune. Under $7K all in. Between the new LT1 and all my mods tuned, my total cost to 650rwhp on a new car will be under $40K. Good luck finding a 400Z under $40K when they launch. The cheapest ones are in the mid $40K and come equipped with an open differential one-tire-fire from the factory. You will need to step up to a mid or premium trim to get a 400Z with a factory equipped limited slip differential. Those will be in the $50K+ range for sure.
