Default Questions on Exhausts and TwinTurbo

I'm sure similar questions have been asked before, but I'm considering of getting FI exhausts for my 2013 NISMO. I'm also hoping to put AAM twin-turbo this winter. With that said, I want something right now that gives me more noise and a little more grunt. I just bought my NISMO in April, and it was really fun the first 2 months, but now I can tell the car could use a bit more power. The car looks a lot faster than it is.


option I have are:

1. put FI cat delete. either resonated or non-res Non-res with NISMO exhausts. has anyone done this? How does it sound? Do, cat back and twinturbo together in the winter.

2. FI cat delete and cat back exhaust now. and do twinturbo in the winter. Assuming putting exhausts on doesn't require tuning, especially without doing any forced induction, or not even cold air induction.

3. Wait till November for the factory warranty to run out, and do all of them together. cat delete, cat back, and twinturbo.

Also,
what other mods should I be considering, if I'm doing a twin turbo? I was told I should change the rear diff cover to the fin-ed type. Add an inline oil cooler. Maybe brake upgrades.

Any help would be appreciated.

Man, you've got a lot of reading to do. You can get the cat back now, but don't buy anything else if you're planning to boost the car. You need a whole bunch of other supporting mods beyond just the kit. Clutch, flywheel, csc, radiator, oil cooler, gauges, boost controller, etc.

The diff cover, while nice, does not need to be changed. Budget half again the cost of the kit for supporting mods.

If AAM isn't installing the kit, make sure someone who has installed one before does it. Don't be someone's guinea pig.

Also, ditch the AAM kit and buy it from Fast Intentions. AAM sent a local guy a kit with smoking turbos and did ****-all to take care of him after the fact.

What are your goals for the car? Are you sure you want to spend $15-18k on your Z to make it faster in a straight line when $3k for an oil cooler, FI cat-back, test pipes, Stillen Gen 3, and a tune will net you about 40hp, some torque, and an awesome exhaust note? Add in some AutoX time and you'll have way more fun for literally 1/5-1/6 the cost of a TT build...

If you're actually racing disregard what I just said, but adding TT to a Z solely for bragging rights is a waste now that there are C7 'Vettes and blown 5.0s running around everywhere.

2 months and you already feel this way? You bought the wrong car.

I bought it because it's a kick *** platform. It's a lot more fun driving my Z, than an EVO or an STi. It drives more like a real sports car, instead of putting a rocket inside an econobox. I've driving my buddy's EVO many times, and it's so much quicker, but the car gets so light as you drive fast, and the handling is crap. But I do get smoked by EVOs. NISMO 370Z goes a lot slower than it looks. Vette, Viper, Challenger SR8, they all pull up next to me and wanting to race, and not that I want to street race, but it's sad that I don't stand a chance. I do have concerns with putting too much power into this car and it may make things not driveable, and turn it more of a drifting machine. I rather do autoX and track days. I don't need more power for autoX and track days.

Well there's your answer. $15k+ is a lot to spend just because you're looking to impress someone who bought a Viper to make up for his tiny little weiner.

Get an oil cooler, cat-back, intake, test pipes and a tune. Then autoX it and have some fun. Most guys with big bad scary cars can't drive them anyway.

One of the strangest posts I've read on a car forum lol

A Z, 350 or 370, is a niche car. People buy them because they love the balance, look, history, and combo out good handling, sporty performance etc. No one buys a Z because its a great platform to make boatloads of power or be the king at High Performance Driving Events on a track.

There's always something faster out there. I had that concern when I was 18 years old. Otherwise being the fastest thing on the street isn't why I buy anything anymore.

I had a b20 vtec 1995 Civic hatchback, that was faster than my 370z in a straight line, but I wouldnt trade one for the other.

I've never in my life heard someone refer to an Evo's handling as "crap". They are dynamic high performance platforms shaped like a loaf of bread, but the handling is some of the best you can buy, never mind adding in upgrades.

To bring a 370z reliably to the track, for driving events, start with a large oil cooler, upgraded brake pads, high temp brake fluid, and tires that won't turn to grease after a few laps.

Good luck building a 370z with a twin turbo kit, and having it survive an HPDE day or two. Apples and oranges. Driving events are about improving the driver, not the car. Have you ever done an HPDE?

You sound all over the place.

If you are concerned your Nismo looks faster than it is, trade me your Nismo body kit for my base
If money is no object get a catback, test pipes an intake and a tune, you won't need your cats/intake after you go turbo. Also get some suspension mods, I have a base with swifts (not sure how much of a difference these are vs Nismo) and they made a huge difference, I'm getting ready to do more on the suspension, that's where I get the most joy in this car is in the corners.
