It depence how much you like the G.
I ran into the same situation a while back.
I was thinking about if I SC the G or get another car like IS-F, C63, R35 GT-R or a used 996 Turbo.
Never thought about the E92 M3 coz with options it comes very close or even more expensive than the R35 GT-R.
I went with SC the G.
Now I think I should have got another car.
I still like my FI G but I should have spent the money on getting another car instead.
Especially the C63 is so tempting for the performance and value.

Besides, you will have a hard time selling a modded car.

 

BOOST! you won't regret it as long as you do it right the first time.

 

My advice is to only go FI if you're very good at working on your own car and really enjoy it. FI will hurt the resale value of your car, not help it. You can always demod but then you'll also lose money by having to sell your used FI.

You may be better off by selling your G and buying a car that you're happy with stock. I went from a GTO to the G35. I miss the torque of the GTO but the G35 is so much better in every other way. I have no regrets.

 

I dont know man theres alot of really nice cars out there that you can get pretty cheap. It really depends on your money situation. You still owe 21k on the car. If you have the money I would go buy a nicer more exclusive car. Our G's are very common. Infiniti made more then they should have IMO it would be nice if it was more rare. If you have the money Id get a Porsche. Any one. But then again I have always been a huge Porsche fan. That's probably my next route after the G some sort of porsche that I can have fun with on the weekends and nights out.

The "IS350" really threw me off. If you want something fun, look elsewhere.

I was (and still somewhat are) in the same position as you are. I was really looking in to the 370Z because the VQ37VHR has been proven by the G37 guys to make GREAT power with full bolt ons & a tune. A full bolt on, tuned, with an aftermarket suspension 370Z would be a blast to drive.

But at the end of the day, I've spent too much money on the car already. And I really love this car- great fun and turns heads everywhere I go. Its just not worth letting it go (my 3 year lease is almost up). I will most likely keep it and go Vortech.

The IS350 isn't as quick as the 370Z. It's more up to par with a G37. And is inferior to the G/Z in the handling & fun department...and no 6MT.

 

I have a G and I love it. I am currently going Vortex and hopefully reach 400rwhp on the DD dyno. None the less I love my G and there is nothing else sweeter. Most of all you have a better chance paying off your car vs a new car with a new car note. What it come down to is what makes you happy. I can only give you my option and nothing else.

 

370z all the way.
