I have both a 997 turbo and a gt2. I am thinking of selling one. The 997 turbo is faster but I was wondering what it would take mod wise to equal the feel/times of the 997 turbo? Would the stage 1 or stage 2 do it?

Thanks for the help

Stage 2 should take care of it. Stage 4 is where you will eventually end up.

 

Is this the package I should be looking at? ? on some though.

K&N air filter
free flow exhaust with or without new headers?
re-mapping of the ECU
EVO Flow
billet divert valves?
Hose kit?

Thanks again

 

Sounds like a pretty good list.

 

The GT2 is a real keeper in my book. Do an ECU, diverter valves and an exhaust and you're set on the GT2.

 

I have the following minimal engine modifications:

GIAC controller (hammer program) with stock, 91 and 100 octane programs.
Europipe stage II quiet
Diverter valves
BMC filter

My GT2 is substantially faster than stock and a 997 Turbo. I ran 30-100 against a buddy and repeatedly put him down by 2 to 6 car lengths (pending who launched first).

The 997 Turbo is certainly a better everyday car. But given you list of cars I would keep the GT2, long term it is a much better keeper than the 997 Turbo.

just sell the vette and old m3.

 

Woooh,

You have both car than you must know...

Just comparing numbers it seems the GT2 should be faster. I guess it depends a little on how you drive. Low end torque for sure speaks for the 997, the weight is certainly in favor of the GT2.

Was there ever a race recorded between the 2 cars?

GT2
3175lbs, 461hp @ 5.7k, 457lb @ 4500

997tt
3495lbs, 480hp @ 6k, 457lb @ 1950

 

I agree, GT2 should be faster.
The drivetrain loss on the 997tt is huge.

 

My stage 2 TT (K16) ran head to head with 997TT, I believe you just need new program with your GT2 to out run 997TT.

 

I'm surprised you are saying your 997TT is faster. Have you raced them head-to-head, or you judging it only by feel? The 997TT will 'feel' faster since it makes more torque earlier, but from a roll (as has been said), they should be very close..with the advantage going to the lighter, more efficient GT2.

 

Yes, it just feels faster. I have not put them head to head. Rolling start to 60, 80 or a 100 the 997 seems faster.

 

Does the ECU programming rasie the redline? I keep bouncing off the rev limiter.

 

My flash raised it to 7000.

 

You can keep your stock headers. They are good to 600 HP. Exchanging them for a set of ported and ceramic coated OEM headers would be a bonus. You need to add an exhaust to your list. I feel Europipe is the best choice.

At this point you would be ready for a stage 4 flash.
