370z 7AT - Need Suggestions/Advice

[Leroydsouza]

Hello everyone

Recently (2 Months) purchased a 370z 7AT 2014 New from Local dealer (Dubai) GT Edition - Courtesy of CarbonSignal
Should have not rushed and bought an Automatic but they did not have the manual and it would take 2 months. No Way. Was picking it up from the showroom the very next day

Mods Currently are

1) Akrapovic Evolution
2) Motordyne ART Pipes ( On the way being Shipped)
3) Swift Springs
4) H&R 20mm Front & 25mm Rear Spacers
5) Motordyne M370

Coming to the advice/suggestions part,

I know what i want to achieve from this car (atleast 500 WHP) with reliability.
My knowledge about this stuff is umm still building so excuse my 'noobishness'

Yes i have done the search and been reading forever, But its time to plan out my remaining mods and i prefer a more direct approach.

1- Twin turbo or Supercharger ? Considering my location and transmission, Will TT hold up ? i lean towards TT because it seems to have a lot of potential . Stillens Supercharger may be great but its results dont seem to be satisfactory to me.

2- Will Valve body upgrade do the trick to support the FI route i go ? Or do i have to rebuild the transmission ? i honestly dont want to ship my entire transmission to and from someone in the US. And i dont trust anyone locally enough to do this job.

3- Transmission cooler and Oil cooler are on my list and probably will be shipped soon. Any other supporting mods ?

500 whp and DD reliability. Thats the goal. Time of completion and Spending a little extra for reliability not really an issue since i am not in a hurry.
Please bear in mind my shipping costs it hurts when i pay as much for the shipping as the product being shipped.

Thanks in advance for reading and providing any suggestions etc
I pretty much wanted a Z for 5 years but only just recently purchased it. Done my reading, Done my research, But i would like to get some direct answers now
