I own a 2003 GT2 and was wondering if there are any upgrades I can do. I know that a lot was done at the factory but not sure what was done and how different the 911TT and GT2 are ?
Am I just better off leaving it stock ?
Maybe I can update the ECU ? Not sure and dont know who to ask.
Not many shops are familiar with the GT2 and I dont see much on upgrades for this car..

 

The possibilities are nearly endless....

Thank you..
I will check them out

 

I think you should keep it basically stock. Flash, diverter valves, upgraded wategates, Exhaust. 600 HP, basically stock.

Keep all your stock parts. You have a collector, enjoy it, but keep all the stock parts.

Be careful there is NO stability control. Don't lift mid corner, no matter what, just nice and steady.

Everything above is 100% reversible in less than 4 hours.

 

Any engine upgrade available for the X50 or Turbo S will work on the GT2

Retrofit the GT3-RS suspension and you'll have one of the best overall performing cars out there

 

Whatever you do, DO NOT GO CRAZY with the power. Keep it at 600HP and you will be a happy man. Anything more, and the car is a total monster which is very hard to tame.

 

heck with that work on the suspension!!!!! and you can drive the **** out if it just like it is!

but deffinate keep it around 600 hp if you want to drive easily and get power to the ground

 

Proto ECU, Exhaust. airfillter u will be super happy

 

Get in touch with Dr. Jitsu, Paulie or S-351. They all have modded gt2's...from different tuners. They all make over 600hp. Easily.

 

As many have already stated, a flash and dv's would be a great place to start.

Let me know how I can help. We can custom tune the car for you here in CT if you are interested.

 

Love to see pics

 

that would be ~550 HP with pump gas...

 

I would do my old setup. K24/18g, Protomotive tune, EBC, 5bar fpr, DV's, GREEN filter, and 100 cell exhaust or no cats. You'll be between 600-650 hp, very reliable and relatively inexpensive. If you need a shop to do the work I would recommend Protosport in Pompton Plains, NJ. They are strictly a Protomotive shop and do awesome work.

 

I have 24/18's, proto ecu,EBC, 5 bar fpr,switzer exhaust,dv's,bmc filter & it hauls ***!!!
I will stay with this setup as it is easy to put back to stock.

 

Another option is to dust the sand from your Vagina, install GT30's, fuel system, triple carbon clutch, exhaust and have the fastest all around car in your neighboorhood.
