I have a twin turbo 370z 7AT. Probably the most controversial to boost because of the 7AT. My first transmission blew due to tuner not adjusting torque management. Got a new tranmission under warranty and had another tuner tune car. 12000 miles later couldnt be happier 485 whp on 7psi and car is my DD.

Was going to sell car because another baby coming to household soon but I might just swing another car and keep the Z. I just cant seem to part with it especially boosted!

When you say your 7AT blew, is it the good ol' 5-7 gears start to slip?

So it could be that some of the issues I have read which made me start this thread, could be a change in a persons life i.e.. a baby or something breaks and people just give up or get fed up and dump the car??

One big question I have for you as a 7at owner myself is how did you get Nissan to replace your transmission under warranty being boosted

I sent my brand new IPL to GTM to have it twin Turbo'd at 3k miles.
Since then I have had several "minor" issues that keep me ALLWAYS on my guard.
I have no plans o sell the car, in fact I was hoping to drive it for a very Lon time.
I'm slightly over 500whp and love the power. The car is a true thrill, but at a price. I KNOW I will have to sink more $$$ in it as I drive it hard. There is ALLWAYS the cost in the back of my head. I think this is the reason people get rid of their boosted G's/Z's.
If I had the dough, in hindsight, a Turbo'd M5 or GTR would have been in my garage. But saying that, I don't have the $$$ and my G37 is a killer sleeper car.
I know I will likely have to replace/rebuild/upgrade the trans at some point in the "near" future.
Not having my own "shop" in my garage means that I have to call my install shop every time my car runs rough or I get some funny noise or error light. This can wear on you.
If you do commit to FI your ride. Estimate 2x to 3x what the shop says for timing. This will save you MASSIVE brain damage from waiting for your project to be complete.
Good luck!!

You were the first 1 with the 16g kit right? GTM won't get back to me with a price. Could you message me what I'm lookin at for price ?

Very true, I am glad I found a great dealership who did my install and allowed me to do warranty work even for the transmission.

Not all are like this, but going into the forced induction car on a N/A vehicle can be a big expense and many underestimate this amount. I have been boosted with a SC since 19k miles and just over 50k miles at the end of the year (and a time of about 2.5 years). I have yet to track my car (ring or 1/4 mile) but I do enjoy the fun street driving, plus the pain of daily driving the car. It is a blast to drive but it is not 100% perfect but I never expected it to be.

It comes down 90% to expectations. A large number of people have never taken on a project of such cost and magnitude before, and it can surprising what you need to invest (both time and money).

That makes a world of difference, and have to outlay cash for those things while dealing with a shady shop makes for a completely different experience.

Wow... How do you guys find dealers that give you warranty even though you are boosted

I asked my service advisor who is a cool dude if I boosted my car would I still have warranty? He said honestly you would not as Nissan would say the FI created the additional stress that caused the failure. If any alterations you do to your car can be linked to the breakdown you will be denied

He said this to me in a very sincere manner.

Some dealers will play ball, some won't. The dealer installed mine.

If I had to guess why people get rid of FI'd Z's, it would be that they cut corners on the build and/or install, and have nagging little issues that eventually drive them nuts. The guys that have no problems seem to be the ones that bought all the supporting mods, and had it installed by a shop with experience with that particular setup.

As far as reliablity goes, I figured that if the car can handle 500-550whp without a problem, I'd aim for the 450-475whp area and be happy. That's still a lot of power, and the car's my daily driver. I don't feel comfortable running something right up to the ragged edge. Still need to get it on the dyno and see how close to that number I got.

When you say supporting mods, are you referring to oil coolers and (for the 7AT folks) transmission coolers? Are there any other mods needed to safely support a boosted vehicle?
