I would leave it stock for baseline stuff at the track, maybe 3-6 mos, then really want first thing is a better sounding exhaust. That one video by Raiti's really shows the weak sound.

What has worked best on the 370Z for catback or turboback as far as sound and weight, durability? Ark, Powerhouse, ???
You're better off looking at the Q60 red sport, not the 370z for comparison.

Personal preference is dual - quad might look good if not as large as the ones in the picture. I’m sure some of the tuners will have a quad tip option as part of their range of exhausts.
Yeah it'll be interesting to see who is the first one out the gate with a quad exhaust option and other accessories. I think i'd still stick a dual setup as well but with the right size a quad setup will work nicely on someone's build.

I'm hoping to have the majority of the mods I want done on day one. Hopefully manufacturers get their hands on the specs so they'll have parts ready by the time it's out. That said, I'm not a fan of the quad exhaust look on the Z, so I won't go that route.

Yeah I really hope Nissan has been secretly giving tuners cars to work on like Toyota did with the GR86.

GT Radial and Chris Forsberg are teasing some mods for the Z. At the very least a new set of Rotiform rims and GT Radial tires.

Welcome to California where ECU tuning is now illegal! I'm not too concerned because I like suspension upgrades.

I'lll go with full polyurethane bushings on the sway bars. then if the struts aren't adaptive, I'll aim for full coilovers and some camber kits.

Was never a fan of the engine parts so I'll just get a reusable, dry air flow filter.

I was just reading an article about the ECU law and it seems that only a small amount of cars might be affected by it. Road and Track spoke with SEMA director of emissions compliance Peter Treydte about it.


"So far in the two weeks that have transpired, we have seen zero instances of concern," Treydte told R&T. "I really don’t think that this is problematic."

The SEMA executive explained that only a tiny number of California vehicles are likely to be in violation of the new rule. Treydte says BAR shared data with SEMA estimating that, out of the roughly one million vehicles that undergo smog testing each month, only around 150 to 300 cars are expected to fail due to an illegal ECU tune. For comparison, around 10,000 cars fail every month due to mechanical problems or other non-ECU issues. These estimates should be trustworthy: BAR has had the authority to run this program in California since 2013, and has been collecting data on the ECUs of cars being tested since 2015.

That data has shaped the rules that are now being implemented. Treydte says the data BAR has collected can tell the agency how many vehicles are factory-tuned (i.e., with a post-purchase computer update) and which are running aftermarket software or computer hardware. "They know which of those aftermarket modifications are legal, associated with a CARB Executive Order," he said. "They already have that information. What’s happened here as of July 19 is simply an implementation of a failure condition during smog check based on some of that data they read from an ECU."

Donut Media has a pretty good video explaining this situation with ECUs.

If you are planning on modifying your Z, Are there any specific mods you plan on adding once you get your hands on it?

For exterior mods I've been looking at getting a new set of wheels and tires. Performance-wise I think I'm going to wait a bit until other people start tinkering with their Zs.
Mods just for the sake of modding makes no sense to me. I’ll wait to see how well the car is from stock and be patient for the usual mods, but I’m holding out for the Nismo so I don’t imagine there’s be anything to do but a catback exhaust and maybe upgraded sways. As is, it’ll already be a formidable beast. I’m not into lowering or oversized wheels or any warranty-ending mods. I’m relatively easy to please as long as the car is well-sorted to begin with. Given that the Z is essentially a parts-bin special (with an admittedly new interior/dash), I have every reason to believe it’ll be good to go.

I just joined the site but will chine in here. I just turned in my leased 2019 Q60 redsport back into infiniti last weekend. I loved the car but am looking to get back I to a Z as I've owned 3 previously. When I got my Q my immediate mods were clear bra, window tint, lower down pipes and a CBE as the exhaust was way to quiet. I pulled the LDP and CBE off the car last weekend along with my HKS blow off valves. The Q does suffer from heat soak but I live up north so it didn't happen very often. In a warmer climate the upgraded AMS heat exchanger seems like a must. I will likely start with the same mods on the Z and am hopefull I can trim my exhaust for the Q and have it fit day 1. We'll see. The engine layout looks different on the Z from the Q so not sure on the BOV yet but they were great on the Q. Window tint is day 1 for sure. I am hoping it won't be impossible to get in on the first batch of Zs to the market as I am ready to buy today.

Hoping to be able to use some Q50/60 and 370 parts straight away. SSQVs, 1.5way, full downpipes, intakes, etc. Also want to tune on e85 as soon as its possible. On day one I'll probably make my own exhaust modifications to the stock catback and get wheels/tires, eventually some suspension down the road. Then prepare for that closed deck 3.2L and big turbos? 🤷‍♂️

Welcome to the forum! What horsepower and torque gains are you after?

My hope is that the ecutek tuning solution used on the higher hp Qs will also work with the Z and we can be over 500 wheel pretty much at launch with just that and a few bolt ons. I'd like to max out the stock turbos and then chill for a bit while I get some inspiration from the 1000+ hp builds as they start popping up.

Will you be tuning it for any specific type of setup?
Can't wait to see some more time attack tuned Z's and even others more suitable for the 1320.

Nothing specific here, i tend to just enjoy heavily modded turn key street cars that I can drive to the track, on the track and then back home or to work when i feel like it. I will definitely be looking to do a little bit of everything with this one. Mostly just for fun :)
