Need advice for 370z mainly track

ytian9

Hi, I am new here, I just want to get a 370z for track use as i have other cars for daily.
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, remove all the modification parts except intake, header and exhaust, and then 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.

Thanks

English is my second language, sorry for confusing you.
I just need some advice about these two vehicles. Thanks for reply.

The '09 is horsepower heavy. It needs work for doing trackdays. If you haven't done trackdays before. It will kill you.

The '15 has a lot of stuff already done for the track.

Don't know how much experience you have in doing trackdays.

You said 09 needs work, do you mean the stuff from 2015?
How about put all the stuff from 2015 to 09?
No experience at all, but i will learn by driving "slow " at first.

I'm assuming since he's asking this he will be inexperienced.

The 09 has no additional aero to deal with the extra power to the wheels. That alone will be a headache to deal with even with a decent amount of track time, I know. No car is built to withstand track abuse, eventually something will go and cost money to replace, I had to replace my transmission when fifth gear's synchro disintegrated. Not to mention all the times I came very close to walls that could have turned out to be a complete loss of the car.

What you really need to have a good 370Z track day car.
Oil Cooler, Sport Brakes and track pads + fluid, Good tires, Anti fuel starvation system

Optional (this will negatively impact daily driving (noise/comfort) but give a good boost to track performance)
upgraded coil overs, upgraded sway bar and end links, Upgraded diff

Any other money should be put to seat time and instruction and safety equipment (which can easily be +$10K).
Seats, Harness, Harness bar/roll cage, data logger, etc.

In the very long run the 09 will be better if you & it make it there. Its kinda like starting off with a 1000cc superbike instead of going through the normal progression of learning from a 250cc one. Sure you can do it but it's a bad idea.

You bought a used, modified car …that you never drove?

I wouldn’t trust any car that’s been turbine by someone else. N]who knows if the work was done competently


Punt the 09

Get the 15 AFTER TEST DRIVING IT AND INSPECTING IT

Whoever turbo’d the 09 without any suspension mods is a fuckin idiot

I say a couple of nice Z's. I'd have the 09 to a good tuner. See how the motor is. Is it damaged? If after a complete review by tuner: Install upgraded oil cooler. Install adjustable coilovers and have the supension checked and dialed in by a professional.
If you were closeby. I'd recommend a garage in San Jose, Ca. They can fine tune it like a watch.

Mandatory
34 Row oil cooler change oil prior to each even.
Brake Fluid RBF 600/660, Castrol SRF, or better; and a tool to check water content.
Brake Pads Carbotec XP10 front 8 rear or better.

Very useful
Fuel Starve fix, CJM
A track app that overlays video with odbii info.
Prepping your car and getting a good nights rest before you arrive at the track and doing multi day events.

Also Read these great tips and info.

After you've read those I can help you spend tens of thousands of dollars on important items like safety because I am just assuming here you are more valuable then your car.

I’d add sway bars to the very useful category. At least to me the stock had way to much roll and pushed like crazy in stock form. Switched bars before even first track day as it was terrible just on freeway on ramps.

2011 Nismo#91

They are very useful and "relatively cheap" but you need end links with them. But not having them will not ruin your day.

I'd use that money first for:
Track Safety Gear:
A proper set of racing fire retardant gloves, shoes, socks, and under garments. Bright color gloves help with point bys.
A fire extinguisher and mount. I use to following
The Bracketeer Car Fire Extinguisher Bracket
Amerex Handheld Extinguisher - Halon 2.5lb

Those things are nice but realistically how many people at the track actually have all that and this is his first track experience (if I read right). Odds are he will need a lot of track time before he’s even near pushing it to the limits to require all that. Just get the car in a comfortable spot and learn slow and safe.

Elmo370z

I agree he more then likely will be at 30-40%

2011 Nismo#91

You're right, that's why I didn't list them as mandatory or even very useful. It was suggested to get sway bars too but I though any one of those would be money better spent initially.
