Bigger **** envy
 

I've reached a point where I feel like I'm in front of a wall and there are just two ways around it and I'm not sure which one to pursue.

So....what I'm talking about it power. My 370z is upgrade on every front that I felt made sense. Braking, cooling, drivetrain, suspension - all boxes checked. All parts are top notch. They're all well tuned and perform excellent. The issue that I now have is.....the ****. Power. I feel like my car is just too weak. And I'm not talking about traffic light jerking off. I'm talking about racetrack fun.

I've had the Z for 5 years. During that time I upgraded part after part when I felt like the current one isn't up to my liking/skill level. I feel that right now the car is just a dream to drive, but it's weak. Maybe I'm spoiled, I don't know. But this is now the wall that I feel like I'm facing. I felt it at the beginning of last season but I convinced myself that there's no need for more power, that I still have more skills to upgrade. One year later I'm even more convinced that I'm just lacking power now.

So....what do I do now? One obvious answer is - supercharge the car. I am considering this, as it would be a logical step towards the ultimate fun car - it's already got everything else. But will the supercharger bring enough bang? I dunno, I haven't driven any boosted Z's.

As an alternative I'm looking at a C6 corvette. I always thought it would be my #1 alternative to the Z. I haven't driven it so I'm not sure whether it would really be what I'm looking for. I also think that it would surely require upgrading certain parts before it would reach the handling of my Z.

Rant over. Give me your input. What are you guys's thoughts on this? Would you supercharge the already excellent car? Would you make the bigger jump toward the V8 and unlock more of everything immediately, with the option of later upgrades going even further? I am stuck. Thanks.

1. would you get the Vette AND keep the Z or look to part ways and begin a new build with the Vette?
2. if power is what you are looking for - have you considered a MK5 Supra? Lots of power with simple bolt-ons and a lot of people feel the car out of the box is already a great car - do some slight suspension work on it and from what I understand its a better car all the way around vs the Z (and this is coming from someone who owns a Z and love it)

I'm actually headed your way in the fact I have all the parts I want to make the suspension be more dialed in and stuff - and right now - its has the typical power mods of a CBE, HFCs and intakes - along with a tune but it just feels slow compared to a lot of cars in 2026. Part of me wants to get a daily and then supercharge the Z bc of how much I'll have into it so far - else if I were to start over again - I would lean towards a Supra or a Honda CTR - where I'd lightly mod the CTR and make that a daily/forever car as well.

It's more fun to drive a slow car fast, than to drive a fast car slow.

Boosting the Z opens up a can of worms most people can't get a handle on. There is a lot of trades offs in doing it. And you better have a real good tuner. Stock block, around 500 ft lbs of torque is the limit, and about 16 lbs of boost. The torque is the limit on stock rods. Over 16 lbs of boost and you start lifting the heads.

Get a car that is oem boosted. Or oem with big power.

Thanks for the input guys.

You have both reflected my thoughts and this is why I'm struggling for an easy solution.

I wouldn't get the c6 alongside the z, i'd have to trade it. Not sure what's best.

Dave on discord sold his Z and got a C8 Vette.

Have you swapped the 3.69 stock FD to 4.08 FD? If not, then it might provide the 'bang' you're looking for at the track without the need to boost your Z (and avoid opening the can of worms that Rusty mentioned), as demonstrated in the acceleration comparison video attached to this reddit thread: https://www.reddit.com/r/370z/commen...f_these_tests/

It's the same in the airplane world. Constantly want to go higher, further and faster.

cars are easier to achieve those goals but as in airplanes, it's easier to buy something that already comes with the bells and whistles.

You might pay up front for it, but definitely easier in the long run.

But will you get bored with 500 Hp or having nothing to do on the car? ;)

If your focus is the track I think I would look for a different car unless you are in love with the idea of keeping and boosting the Z and throwing stock blocks at it. Corvettes are nice.

Cheers man. That's my video :)

That's a good point, but I really (maybe naively?) believe that 500hp is more than enough for the Z and in general for ALL the fun you'd want in a car. Maybe I'm really naive here, I don't know.

The track isn't my only focus, but the fact is that the Z is my fun car that's primarily used for either a road trip (just me and my gf and a few duffel bags) or used on the track. And for that it's perfect! Other than the power aspect.

And honest question - what do you mean throwing stock blocks at it....is boosting it so risky? I always had my eye on the basic Z1 kit (or similar) that gets you to 450-475hp which I believe should be enough. Is my thinking naive here, that the stock block should endure it no problem?

Actually, for a supercharger that sounds like a good power target for longevity. If it is mostly a street car that should last a while with a good tune and supporting mods. I don’t know a lot about the quality of the Z1 kit though. What I meant by my last post is: any time you take a boosted Z to the track, I would be prepared for anything. Maybe some track rat boosted folks if there are still any around can chime in.

High 20's is more in the head lift territory. But everything else is spot on. But damn it's fun driving a turbo Z ��

The real problem with the platform is that there is no recipe for success. Every kit out there has limitations. For a track car, it would require a good bit of custom work. It's not cheap. I can tell you what you need but you can't go buy it off the shelf somewhere. Don't even think about boosting a stock block. It is a disaster waiting to happen. Your day will come on those. It may be two days later or 4 years later, but they all let go. Just enjoy it as is.

In my opinion, it's hard to beat a twin turbo 370Z. I've driven just about everything. From customer MK5 Supras with suspension setups that I've built and tuned, to my own 1,100 WHP GT-R, C7s, C8s, Caymans, and Boxsters. Nothing has matched the overall fun of a properly sorted 370Z. The only car I've driven that felt better straight from the factory was a 911 Turbo S.

Supercharger kits can definitely be enjoyable, but they're not my preference. In my experience, they tend to have more reliability issues over time, and they're nowhere near as stealthy as a well-designed twin-turbo setup.

I have quite a few customers in Poland who regularly track their stock-block twin-turbo 370Zs. When the car is built and tuned correctly, it can run with 911 GT3s and other serious performance cars. If possible, I'd recommend getting seat time in both a supercharged and a twin-turbo Z before making a decision. The tuning calibration also plays a huge role in how the car performs and feels.
