A 900 Wheel Horsepower Nissan 370Z

shadow85

Rite, I am just trying to gauge if it is worth building my motor. I want to make a 9.5s car, but only if it can still be a comfortable street car and not too mental to be able to drive on the streets.

I heard BulliTT said that these cars chassis are not meant for over 700whp, it starts to become too violent and unbearable over that point. So if I can make a 9.5s Z with 700whp and still be a fairly comfortable street car, then I will go ahead with all the work required. Otherwise I will want to change to another modern platform that could do it more easily.

Just starting to do some research into this now, about to read your thread, but almighty 300+ pages.

With the right setup, 900whp is drivable. You will need at least 800whp to get in the 9's. Lots of stuff needs to be upgraded for the drag strip. The other question is, can you drive it? I know you have had issues before with traction. What scares some people does not scare others. It takes time in the seat to get comfortable. It's doable, the question is how bad do you want it?

Pretty serious about it. I have some cash stowed away ready to throw at either building the Z more, so I can hit my goal of mid 9s,or sell Z and build new platform. I love the Z, but I don't want it to be to unusable if I can hit my target.

Also, if I am able to hit my goal, I would hope that the motor does not need a rebuild after each few passes, that would be a head ache to deal with too. So I want it to be able to handle the abuse, few pulls on a strip, then the rest on the streets on the weekends without worrying too much about the motor letting go.

Sell it. Only way you running 9.5 with 700whp is with a th400, powerglide of a Dct. And you have to hook like a bat out hel l. A guy in a 300zx ran 8.90 with a unopened motor making 780whp. But he cut a 1.2 60’ (th400).

Definitely the best idea, Zs aren't meant to be 9.5 second cars that you can daily aswell.. The GTR is there for that duty.

The money you will have invested into this platform to get to your mentioned goals both power wise, with reliability goals isn't gonna be worth it. The motor will be on the razors edge and something WILL go wrong eventually. Ask Spooler, who's went down this rabbit hole. Two things to note about if you choose to go down this path, be prepared to do A TON of research to educate yourself and plan ahead for the eventual next step. Two, and this is a big one, you WILL PAY for proprietary information. There are a handful of guys who have sunk $$$ into this goal, with "secret" information discovered/developed through their builds to get them somewhat "reliable". Cost of pushing the envelope and this information WILL NOT be given freely. You have to remember, this is a mass produced car with a mass produced engine. Can it be done, sure, there are a handful of guys who have gone into the "dark side of the moon", but most are lost to the void these days.

For your end goals, sell the car, get a R35 GTR (or whatever platform you deem appropriate for your goals AND can handle the abuse), kill tires and park it. Rinse and Repeat.

Couldn’t agree with this more.

But if you want to attempt. Big big turbos, spray, and practice your 60’. Your tuner will be able to control torque better with bigger turbos and can use the spray to help Spool the turbo off the line and inbetween shifts. . Problem with 98% of anyone with these VQ’s is that they run to small
Of a turbo or turbos. Get yourself a 4.5 to 5 inch intercooler and let it eat. Cjm car ran high 9’s and could of gone faster. I believe the stock motor can handle 900whp ( for a short time) if you can manage the torque.

All I can say is wait. One car is being put together now with an auto and he is a drag racer. Me, not so much at all. Wait and see how his car does. You will be dropping 50 to 60k for sure. Not going to lie, it is damn hard to get these things to live. The trans is the problem. Auto or manual. They both suck. Then, head lift. As was stated above, you will be fighting a loosing battle and developing the car on your own which is not cheap. I am trying to figure out what I am going to do myself. A VR38 swap is sounding good right now. The problem is I have to start over. Not sure if I am willing to do that.

BlueRanger made it into the 9's with an auto turbo car.

shadow85

Nice, thank you, I will try and reach out to this guy, check out his build etc.

GR Supra is pretty easy to get to 9 seconds. Way easier platform to make power than the 370z. If you don't mind the looks/automatic. (manual coming next year?)

It's kind of comical how easy it is to make power on them. Folks are calling it the "next gtr" because it's filling that niche.

But you'll need a 2020 model. Or be willing to reflash and swap in 2020 ECU somewhere in russia. iirc

In all seriousness, if you drive the car as intended at those power levels a stock block won't last long. Yeah, you can tune the torque out of it but what is the point of that. That makes it slow. Great dyno number but a slow car.

Spooler

10k for shipping is a no go.

Elmo370z

This is only way to fit large enough turbos to attain making big power reliably is the z chassis. That diff is what needs to be so you can passes without the worry of it failing. Obviously this is an overtop the build, but kinda give you an idea. Space is a downside to our cars, piping is to small, intercooler are not large enough, hot side of turbo are undersized. Everyone follow the same cookie cutter recipe

Being the guinea pig can get expensive. Just letting you know up front.
