SpecG 997.2 Turbo S
Problem please help, GT2RS conversion - SpecG 997.2 Turbo S
Hi guys,
Just joined the community
Also just picked up a 997.2 Turbo S with 9ff mods..1800miles. She was all wrapped in matt white before and I just stripped her naked to her skin, washed her and..she so smooth and fresh.
For now, I'm planning to put the stock front and rear bumpers back on..and also center lock RS wheels I think.
Here some photos of her

I did Softronic remap on my 2012 Turbo and worked great. The benefit is you get the original file and can set the car back to stock anytime you like. Also you can remap the car and set back to stock at your own house on your own laptop. With the GIAC, they give you a flasher to select between different maps...but the software is hard coded into the ECU and all the handheld flasher does is selects which mapping to use. Your ecu is not technically back to original form.

Got the wheels, center lock kit (black), and the tires.. these are GT2RS wheels and tires specification. I am doing the complete GT2RS conversion with all factory parts.
The tires are Michelin Pilot Sport Cup
245/35 19 25.8in
325/30 19 26.7in
I am not sure if the tire diameter from the GT2RS will cause any problems to the turbo 4wd system.. if anyone has any experience please lend me a hand.
EDIT -
Ok i just found out that the stock Turbo tires are
235/35 19 25.5in and 305/30 19 26.3in which makes them 0.8in diff. and the GT2RS has 0.9in diff.. so I think I might get away with it.

Sorry for no updates on this thread as I have been busy with real life work. I am glad to say that the project has been completed.
I just wanted to share the journey and the outcome.
Final Spec (weight reduction -30kg) -
997.2 Turbo S PDK
9ff ECU 640hp
9ff Exhaust Manifold
9ff Turbos
9ff Suspension with Lift System (+3kg)
Akrapovic Exhaust 100cell Cat (-17kg)
IPD Plenum
IPD Y Pipe (previous Werks Carbon pipe broke up at seam) (+1kg)
GT2RS Carbon Front Fenders (-10kg)
GT2RS Carbon Rear Deck and Wing (-3kg)
GT2RS Carbon Bonnet (-4kg)
GT2RS F/R Bumper
GT2RS Front Radiator and Ducts
GT2RS Wheels and Tires
We begin with center lock conversion



Center locks completed

OEM GT2RS Conversion parts - Carbon Bonnet

Carbon Fenders

Front Bumper

Test fitting before sending to paint shop

IPD Plenum

Werks Y Pipe

Champion IC - which i ditched due to its weight.. really heavy compared to OEM GT2RS IC

Rear GT2RS Outlet ducts

Nearly there! - Akrapovic exhaust to reduce 17kg over hang weight

The bonnet has been sold
sorry
Well one sunday drive, and my carbon Werks Y pipe has split at the seams.. pathetic, waste of money and time. to be honest I had the feeling this is a weak part and I wasnt wrong. (moreover, the inner surface is hardly smooth)
fyi, clamps were torqued at 4.6nm.. boosting at 18-19psi

Outstanding work. I'm currently doing a similar conversion on my turbo so I know that conversion has cost you a fortune with all original parts!!! The carbon fenders alone must have been about $8000! Impressive conversion, well done.
Did you have to change much at the front to get the bumper to fit?

The fronts needed new center radiator and frame, all three air ducts, additional top air duct and removal of front impact polystyrene. The headlamp spray mounting (on the front bumper) was impossible to find so I had to fab a pair out of aluminium.
I bought the 9ff at the price of standard Turbo S. At the time, the 9ff had 3000km and fully wrapped in white since delivery. So it was in pristine condition (coating wise). I hated the bodykit and wheels etc on the 9ff so I wanted to revert to original looks (but with 9ff engine and suspension mod still on).
Originally decided to go center locks with normal Turbo S bodykit but then my bro pressured me to go full GT2RS.. so I did lol.. and here we are a frankenstein Turbo S.
It is still running full 9ff ECU, Turbos, manifolds.
