2005 Nissan 350Z - stock internals

How much power can I run on stock internals?

2000 horsepower or so, for about 10 seconds total. Then it will blow itself to smithereens.

It is a sliding scale - stock, it will run 350,000 miles. Boosted to 500 HP, far less. 1000 HP, far, far, less. 2000 HP, ka-boom as fast as you can say it!

It also depends on HOW you get more HP. Giggle gas (NOX) or turbocharged or supercharged or high RPM.

You can safely add any NISMO S upgrades and not hurt the longevity, warranty or emissions of the engine. If you are still under warranty, the NISMO R parts will void the warranty and possibly cause you to not pass any emissions tests. NISMO S will only boost your HP by about 10%.

Not under warranty… 13 year old car owned by someone who likely wants to add turbos to make loads of power.
