Thinking about buying a 350Z. Mods/Gains

[Dr.Gonzo]

I am thinking of buying a 350Z in about a year to a year and a half. How much are simple mods CAI,exhaust,pullies, Y pipe, header, chip? What kind of gains should I expect or are they worth it? I will probably get the mods one at a time also.

[350G]

The mods are not unusually expensive. I paid about the same money for modding my eclipse & my 350. If I were you, I would get your typical mods, then reflash the ecu to make these parts a "system."

Out of your list, I would focus on the exhaust components first (higher whp gains), throw on the pulley, install the CAI, then reflash the ecu. You also may want to look into getting a new rear gear that takes it from a 3.5 ratio to a 3.9 . . . hopefully, the price will drop by then, but at the moment, there's only one manufacturer. It will sacrifice top speed, but it will send you through the gears quite a bit quicker.

I have an Injen intake and Exhaust kit installed in my 350z. Injen said that these two kits will raise my car's horsepower by 23 HP/18 torque. I really don't know if it did or not because I have never gotten the chance to get it dynoed. If it really did raise it by that much then I think its a pretty good investment.

Dyno from Injen for the Cold Air intake : http://www.injen.com/webpages/testin...age%20gain.jpg

That is where you will find the exhaust : http://www.injen.com/exhaust.html

Hope it helped

Have you gotten close to 300rwhp but haven't touched it just yet?

You may want to consider the following modifications:
Moroso Fuel Super Cool Can - $91.95

forced induction would be the only choice to go for power, majority of NA mods will leave you wanting more.

Hi, I see you've done your home work regarding the 350Z. I have a question for you, I have an 04 Performance edition. The car has been upgraded using the Complete APS exhaust and Turbo systems. The car is basically new with under 2000 miles. I know it's a matter of time before the clutch goes south and I have an ACT to replace it with. My problem is the Flywheel, is the extra noise and drivability worth the change? The stock Fly is a pretty trick peice and the weight is there for a purpose. What can I expect? Currently I'm making 320 at the rear according to a Mustang Dyno.

so, nissan350ztt... could you give us some estimated horsepower gains on each of those mods? That would be really helpful for those of us just wanting to add a little extra kick to our z's

Your asking me a question that I can't answer. All the Mods were done at one time. You can get the APS system With or W/O an Exhaust. The Kit includes everything you need except gauges. I have no cats and I use down pipes which helps. When all the parts were bolted on, it went straight to the Dyno. It's a lot of money but it turns the Z into a nice car. Bassically, you can expect 100 HP over stock if you go all the way.

[danielwebb]

is that with just the bold ons or with the bolt ons and turbo system?

[cd001111]

that's the whole ball of wax, Turbo and full exhaust. The whole thing is bolt on's no internal work is required.
