At GT3RR you get the chance to spec your own build, from the engine to the colour.
If you own a Porsche 997.1 in either 3.6 or 3.8 eventually this engine will fail from Bore score, it pretty normal with this engine which is why we use this platform in particular to install our in-house built and installed V8 engines.
So what do we offer and what do you get.
550 HP LS3 V8
680 HP LS7 V8
700 HP LT4 Twin Turbo
As well as engine choice you also get the choice of body colour, as long as it’s from the Porsche colour gallery we are happy to oblige, we also have an exposed carbon fibre option to include doors and roof from our list of upgrades from our optional extras, we are also adding an interior enhancement programme to our list of options from Alcantara to the Dash, door cards and headliner to full carbon light weight seats.
Get in touch with us today to discuss your Porsche 997 V8 GT3R R13 build.
