Hey everybody. I have an 03' z33 Touring Model, just hit 80k miles on it. So far my goal is to create a full bolt-on and tuned 350z. Right now, I'm looking into the NWP 75mm Throttle Body, but am questioning if it's worth the $300+ dollars since the stock throttle body is already pretty big in diameter.

If it helps, currently installed mods include jwt popcharger w/ z1 aluminum intake tube & heat shield, motordyne 5/16" iso-thermal plenum spacer, X02 True Dual Catback Exhaust, and grounding kit.

Let me know what you guys think about it!

 

it only will really help if you bore out the intake plenum tube from the TB and use a larger matching intake tube(larger than the standard aftermarket tubes) with a good tune. You need to decide whether that total cost is worth it to you.

 

I wanna say the z1 intake tube is 3-4 inches in diameter, but im not too sure, could be wrong. Also thinking about getting a 3" aluminum MAF housing to remove the restriction the stock housing brings. Do you think it could really bring the 12-16 horsepower gain that it says it does without having to bore out the intake plenum?

 

If you read the data, that 12-16HP without a tune. Once you get a tune you're actually looking at 24-32HP. You should get it because NWP supplies a bottle opener and coozy to keep your beer cold while you're driving.
