Will the parts be affordable soon?







I also out myself as a fan of the GT4RS intake. Technically and functionally, I consider this design to be perfect.
In view of this, I desire this very much. Only the parts should cost a maximum of 6k.

Where there is a will, there's a way. If some, I guess 10 members, want this kit, then one possibility would be to reproduce the sidescoops and the Top Cover of the Airbox in CFK, which would cost significantly less than with Porsche.
The intake plenum, the central throttle valve and the remaining parts are could probably buy original from Porsche.
Since the GT4RS has 6 individual throttle flaps (german Einzeldrosselklappen), the CS intake runners should be used for simplicity and cost. The question now is whether the function is given with the single overhead throttle body / valve.
Above all, it has to function technically flawlessly for me. I wouldn't make this investment just for the looks.

Are there some members who would also like this upgrade?
I look forward to your feedback.

Best regards by a newby with a 981 GT4 Clubsport (European street version)

Current price for 4RS nonWP kit exceeds 10k

Just take my money. I’ll buy this in July I’ll report back as the guinea pig

user1029

honestly any GT4RS mod on a 981 GT4 is worth the money given that the GT4RS costs 300k for 2 pedals

Is anyone developing a kit to retro a 4RS intake onto a GT4? I know there is the BGB kit but am looking for something more oem+

DR.S

I could do so, from developing through manufacturing, based on scans of my incoming 4RS and my ingenuity.
But such a kit would cost > 5k and at least 20 enthusiasts would have come together to justify the needed effort.

I gave my shop a heads up of this project. If the following hurdles can be cleared then the retrofit is possible:

1. Direct replacement of the 718 CS IM Plenum with the GT4RS plenum with the vertically oriented throttle body.

2. Getting the carpet to fit, hopefully the 981 and 718 share the same carpet dimensions over the engine cover.

3. Hopefully the engine cover itself of the 981 and 718 are also the same

I’m going to abort this project if it requires any drastic, irreversible trimming to the body.

This video shows all the components being removed from the GT4RS intake.. It looks like it should be a direct fit into the 981.

Thanks for the helpful video, there maybe hope yet that this retrofit works

looks like these are the parts for the plenum

Would love this mod as well. I really like the engine cover as well

Can anyone find the non-Weissach, matte plastic window intakes? Would save quite a bit of money

if all the intake components go on well, altering the existing carpet over the engine would be easy

Le Petit Garage

Perhaps the Clubsport version works? Might be a cheaper part than the street car

DR.S

The nonWP window intakes cost about the half.

The CS ones have a different air guide connection since the air box is different.

user1029

do you have the part number for nonWP window intakes?
