Also has winning RACE PROVEN performance that will smoke maxi's day in and day out. Throw a Magnussen or Mallet SC on the CTS-V and you will have 500hp and no max will even be able to breath your exhaust fumes.

After all of your expenses of trying to make 400hp on a FWD Nissan, you would have spent more money on the Nissan than a true sports car and are still stuck with a FWD car IMO.

The ONNNNLLLLYYY thing you'll be sacrificing is interior space in the CTS-V. If you're tall like me(6'3") and my size(300lbs), you'll be quite cramped in a CTS.

If you got it, why not

HotShot headers and heatwrapped to keep the heat thrust for the turbine.

Since the STS turbo is mounted in the rear of the car I would want to use the heatwrap to keep the exhaust velocity at optimum to reach the rear turbos, then use a front mount active intercooler to chill the charge.

As for the ECU, Jay at technosquare said he could create a generic program, clone a G35 or Z350 F/I program apply it to the maxima for testing, then once its dynoed send him the A/F charts and he'll modify it to optimum tune.

So anywhoo.............. a 6th gen maxima is gonna get F/I sooner or later

Ok, if you wanted to build the "monster" VQ N/A would you use the Cosworth Heads?

I mean, stroker kit, cosworth heads, cams, headers, Fuel Injectors

Also stupid question, does a larger displacement engine run more "rough" then a smaller one? Just for curiosity sake.

Like a stroker kit VQ would it run stupid rough or fairly decent?

I don't even know where to start.

Not necessarily. The only reason the 3.5 isn't as smooth as the 3.0 is because of the higher rod angle caused by the lower rod:stroke ratio, not because it has "more displacement".

There is plenty you can do n/a with the 3.5 without touching the displacement. It still seems like you just wanna throw parts and money at the car without doing any research. Like i said before, visit my350z.com and search so you can get a REALISTIC idea of which mods do what and which route to take.
