importparts pro will build a stroker motor but its close to 10k :/ I contact them a few months back. Kyle's good people

I love me some Z06 action as much as the next guy but I disagree with the line of thinking. If you're not on a budget and want to push the envelope or do something different, by all means go for it. It would be real boring if everyone went for the easiest or most common route to reach a goal.

That all being said, OP if it's your DD, stick to a proven formula.

It's all about the tune and the pertain building the motor. Take your time triple check everything and the motor will be fine. These motors can handle alot of punishment. 400 whp horsepower isn't out the realm for a na build, i figure it will cost just add much as superchargering. 9krpm Z would sounds intoxicating.

the only increased displacement NA Z, if i recall correctly, is Shamu. And that was his race car, which he worked alongside a shop with. JWT (Jim Wolf Technology) would also have a lot of information about increased displacement vq37 and cams.

Well that's a matter of perspective and a bit dismissive isn't it? I'm sure one could find Z06 owners who scoff at "lowly Nissans" just as you scoff at the "common Z06". Personally I think the C6 Z06 is a beautiful car and about as far from boring as one can get without a solid six-figure income.

The op said "the Z can't perform...to the standards I'm accustomed". The point I'm making is the 370Z will never be competitive with the Z06 or 911 GT3 or Mustang Boss 302 or Z28. If one wants that level of performance why drain one's pocketbook trying to morph a Z into something it wasn't designed to do. Unless you just want to.

I think everyone understands the flip side of that coin is some love a challenge, creating something unique and unexpected. If that describes you then "more power to you" and mod away. It can always be done. One could retrofit a GTR engine in a Z if one has the determination, persistence, and resources. It's your money and your time.

Best of luck to the op...

2016 z is suppose to have 450-500 horsepower.

Or a 3.9l 400 horsepower na

Another note the z06 and gt3 and 911 also come from the factory with an significant top notch parts, meanwhile the Z was intended to be an affordable sports car, hence takibg short cuts to reduce cost.replace those parts and the Z can hold its own, and all depends on the driver.

A N/A 350z is making 414whp with ITB and Motec so 380-390rwhp is possible. I'm building an intake system including upper and lower plenum that's kind of like ITB style but keeping the strut bar, so I'll see how much more hp I can get from it. Also, the 288 Jun cam is not needed anymore since ECU Tec is now supporting VVEL tuning and the stock VVEL is capable of doing up to 340 degree or something close to it.

Another intake mainfold project. So your saying will be like 1slow370z one off manifold?

I'll see how it performs first, if it performs well then depending on the interest I might have the team build a few to sell. :tup:

this is still all speculation, there isn't anything out there to confirm this.

If you are really hell-bent on a N/A build -- I would talk to/check threads by BGTV8 and 1slow370z.

As to "reliability", once you start this project, that's all kind of out the window...

If you just want to get the most out of it and want to make sure the motor is holding up, I'd do a compression test, tune up, and get a SC or turbo kit.

When and if something breaks after that, then worry about rebuilding it.

Or... make my dream come true and figure out how to get a A2W IC'd roots blower working on this car :tup:

With all respect I know which platform I want. I also know that I want more power. I want to bring the car to its limits, I'm not talking about a reinforced chassis, rebuilt suspension, big brakes and weight reduction. I'm talking about reliable ways to maintain the Z's feel without risking its integrity.

Is that your garage Shark? Major props if so. :tup:

Also hilarious that someone said to just buy a Z06 and OP already has one. :icon18:
