New Z or TT my 370?
 

So I've been struggling with this one for a while. I've got an '09 Touring with about 120,000 miles in excellent condition. I've got a number of basic additions (dual exhaust, aluminum flywheel, beaded brake lines, cold air intake, hybrid clutch, oil cooler, clear bra and a few others). I also installed Brainiac tablet setup and my interior is immaculate. I am looking to either switch to the new Z or TT my 370 but after weighing pros/cons I still can't come to a clear decision.

Obviously, one way to look at it would be that I've got a 13 year old car and I should just plunk down for the new one instead of wasting money on a twin turbo setup. I am looking for something CARB legal (I live in CA) and relatively low boost for engine longevity (I would be looking for mid to high 400's). On the other hand, I'm probably looking at 60k or so with the performance trim after tax, title, license, clear bra, increased reg and insurance vs 20k or so for the TT setup. I would certainly be getting more power with the TT than with the new 400hp output and would be going with the FI stage 1 TT.

The thing is, although I have no complaints about the new Z, I really love my current 370. I'm just struggling on whether to drop 20k on a used car that I love for the hp gains or put the money toward the new one. I've taken good care of my interior and have a nice tablet setup so the "get the new one for a better interior" is less impactful for me. The new Z has the factory TT setup but at a significantly lower output so that's a mixed bag as well. I could of course just do neither and ride the current 370 into the sunset in its current condition as well but I have been looking for additional horsepower for quite some time now.

Does anyone have any constructive feedback either way?

Car is 10+ years old and over 100k and you're in CA. Now if your planning on keeping the car for many more years and have taken good care of it, the years and mileage matter a whole lot less. I don't know much about CA but getting aftermarket CARB legal TT setup is pretty difficult. So I think that would be your main issue for TT vs New. Personally I am even having difficulty with my NJ inspection and my TT kit, it's always a chore getting everything in the green ECU wise to pass.

Agree with Nismo#91 if you are planning to keep the car then go for it, but your state poses issues going aftermarket FI. I’m in a little bit of a similar situation, had my Z for 10 years just wrapping up my TT kit install, never planning to sell. Good luck with your decision

You are in Cali, Get the new one and save yourself headaches of having to deal your emission issues.

You can always sell it and get a FI kit.

I had a similar "dilemma." Although wasn't going FI, I decided to keep my Z and I'm glad I did for personal reasons.

I'm not sure how I'd feel about going FI on an engine with that many miles, especially in CA.

My simple answer would be to either get the new Z or any one of it's competitors...lots of great cars have been coming out :)

Good luck! I don't think you can go wrong.

I would move out of CA. Failing that... TT that b*tch. Then be forced to move out of CA. It's a win-win.

Yeah, I plan on taking very good care of this car and keeping it into the sunset so it would be a long-term investment. I plan to keep the boost low enough to minimize engine wear and this setup should be OK for CA. That being said, I don't know how difficult it will be in the long term to keep in CA friendly so that's always an unknown.

Having a factory TT on the new Z definitely takes away that headache but I'm not sure how much hp/torque it's going to end up getting at the wheel. Plus I would end up throwing on at least some bolt-ons if I got the new Z, which would just push the out-the-door price up even more.

New body style still hasn't won me over yet. I will wait for the nismo to come out. I'll plan accordingly then. Wouldn't mind have 3 Nismos. Haha

Option #3: Swap the VR30DDTT motor into your current Z.

There are good reasons to move out of California but smog isn't one of them. I have no problem getting my car smogged. :tup: I certainly wouldn't move to a state where you can't drive your car 6 months out of the year due to weather just to not have to worry about smog checks :icon14:

Can confirm... i'm in Mass. Z's are stored for 6 months of the year. Only benefit is it keeps the miles down and something to look forward to, but it's depressing

Or just do what most Californians are doing and move to Texas :rofl2: No smog issues and similar driving year-round weather (just way hotter).

Texas is a great choice. I don't know if I could deal with the heat and humidity though
