Just purchased a 09 GTM twin turbo 370z 3 months ago. I didn't have a chance to drive it yet. And I don't have dyno sheet, don't know how much power it produce. I just saw someone is selling one with tasteful modified 2015 370z for a really good price(just modified last year) . I will post the modification list of both cars.
My questions are:
1, is the 09 TT okay for track? Is the motor going to blow if i do heavy track use.

2, should I get the 2015 and sell the 09 TT. (Worrying about motor blow, as i never drive turbo car before)

3, Should I get the 2015, get all the modification parts from 2015 to put on 09 TT. Put back stock parts on 2015. Then sell the 2015 one. (Almost free parts from 2015)
4, if i am going route no.3, should I just get differential cover, solid motor Mount and all necessary solid bushing(control arm bushings, what else do i need to change?).

My friend running a used car dealership, so i am not worried about taxes or other things.

Any input will help.
Thanks

I use to have at GTM TT kit years ago it's not the best kit the turbo manifolds well crack both of mine did. There was newer manifolds that did come out I got rid of my kit so I have no experience with those . What you have with the kit is there stage 1 turbos that will make 500whp-525whp before there tapped out on pump gas. If I were you I would switch to Ecutek and get a flex fuel kit check the manifolds and see if there cracked and get rid of the Greddy TI exhaust go with a true dual 3 inch Exhaust like Fast Intentions. How many miles is on the engine ? in my opinion you could track the car once you sort those things out and depending on the condition of the stock engine.

Wrong section. You need to take it out the track and see what issues you run into and sort it out from there.

IMHO, a boosted 370z, unless owned and operated by an individual at a very high mechanically technical level, and high level of tuning familiarity, is not going to make it through its first track day. A NA>Turbo car is very different than a factory boosted car; in that the level of molestation performed on the car is quite extensive. Most aftermarket parts are nowhere near track-ready dependable, and a NA>Turbo car is full to the brim with them. The majority of builders are building street cars, with no aspirations of ever seeing the back to back abuse a day at the track will put on them.

If you plan to put your 09 on the track, I recommend getting the car to a serious tuning shop who has real track car experience to have the power set as conservatively as the wastegates allow, and to have the car inspected both mechanically and its tuning to make sure you have the best shot of making it through a day at the track. You will also need to keep the fuel tank FULL, fill it between every session, or the unbaffled fuel tank will cause a lean condition in turns that will almost certainly destroy a boosted VQ.

The 2015 you listed sounds much more dependable for track use. Your turbo car is going to need a whole lifestyle adjustment to keep trackworthy. Its not that you cannot track a boosted 370z, but there are some serious ramifications to tracking that type of setup. Its not going to be a casual experience to just pop into the track every now and then when you feel like it, at least not for long.

So you’re saying all of the fuel components I ordered from your company for my supercharged setup won’t stand up to a track day? I kid, I kid! Looking forward to using what you’ve cooked up!

ytian9 · 11-21-2021, 01:57 PM

Thanks for the replies,
I am not even at entry mechanically technical level.
So looks like I should get the 2015 and sell the 09 TT.
I will learn more by taking more seat time.

Thanks again

What did I tell you in your OTHER thread?

You're a newbie at doing trackdays. The best thing is face time with the windshield before stepping up with big power.

Ya, i got you. I should focus on seat time more.
For that 2015, it already has an OEM oil cooler, do I need to upgrade to 34 row one?

Just found a 2011 soho a2a supercharged nismo
Is this going to be better for me? It's better than 09 twin turbo at least?
The owner said there are 3 maps, 505whp, 475whp, 325whp.
For the beginning, I could use map 325whp.
I know it needs more for cooling - at 34 row oil cooler with thermostat, triple pass radiator, oil pan spacer. Maybe a vented carbon fiber hood as well?
Also it almost has everything that 2015 have for the suspension mods.

Why would you think this is "better" than the TT one?

Honestly, you have zero business buying a boosted Z. None. If you can't work on it yourself then you need a NA Z until you can.

Let alone the fact that he's trying to track the car, not just leisure driving.

-Track conditions (heat...and heat....then more heat.....then more heat)
-FI'd by previous owner
-New owner has no track experience
-New owner has no mechanical experience

That's a recipe for disaster. Lucky if the engine lets go first and stop your fun. Unlucky if something blows right before or during a corner, he loses it to the wall and gets hurt.

Ytian9, go with the N/A one. Sounds like you have the money. The cars will always be here for you to buy. Save yourself.

Congratulations, that's the dumbest thing I've read today.

What part of that confuses you? I'm just pointing out that someone with no mechanical knowledge buying a used car with aftermarket forced induction is a bad idea. Not being able to handle small issues on your own with a project like that is a recipe for disaster, or a giant money pit if you have to pay labor for every little issue.

Let me guess, you're a "drop it off at the shop and write a check" kinda guy?

You sure did bitch about having to work on your car or it being down a lot to have that kind of holier than thou attitude

You guys missed this part. Admin tuning.

I' would run from this. It's a ticking bomb waiting to go off.

Admin tuning doesn't have a rep on this forum. Most of his tunes are copy and paste.
