For what is worth, this is a GT2RS intercooler in 997.1 ducts with the OEM clips snapping together. Just another option.

 

wow that works well. why doesn't everyone just do this?

 

This! Why?

 

Unterduck, just wanted to get to the bottom of this one if you don't mind.

When my car was recently in for the 4 year major service I had Porsche do the install of my .2ttrs coolers. As normally i would have done the job myself I made a point of putting my nose in to see exactly what was entailed given there had been a report from Drvik that the outlets on the new coolers were a touch larger requiring minor packing.

From what I and the P techs saw it was impossible to use the existing .1tt ducting without the use of cable ties on one side of each cooler, along with a bit of trimming on the inside edges...which most are already familiar with. The other side of each cooler however was able to utilize the tabs as your photo appears to show.

Are you able to provide photos of both sides of the cooler to prove you do not need to use cable ties at all?

I assume the photo you show is of the side that doesn't need the ties. Just wanted to clear this up for the members and others out there so everyone knows exactly what can and can't be achieved using the stock .1tt ducting with the .2ttrs coolers.
TIA.

 

Sorry I don't have a picture of the other side OEM clips, but I assure you they are hooked together. I have attached a photo of the completed assembly from a different angle and I have attached some photos of the shrouds as modified.

The real key to doing it this way was to make a modification to several tabs on the edge of the GT2RS coolers. There is a photo attached and highlighted with red rectangles around the area of the tabs referred to. These tabs either need to be removed or bent over 180 degrees. Doing so makes the coolers the same thickness as the originals in the area where the clips will be hooked together. The shrouds themselves then need to be modified to fit down and over the thicker end tanks and such.

I chose to bend the tabs over. This creates a nice rounded edge area for the shrouds to sit against. I then used a bead of silicon along all the edges of the shrouds on the top side to seal them. It took about three hours to do the first side while I slowly removed material and test fitted. The second side took only an hour because you know where to go.

I have more photos and information to share. I'll just do a write-up and submit for the DIY section.

Thanks

This is great information unterdruck and really appreciate you posting up the details. It appears this I/C install has now seen some "evolution" . Both install procedures are effective however your's eliminates the need for the cable ties on the one side and also removes the trimming procedure. Very good thinking! Kudos and reps to you!

 

Hi, reviving this old thread to see if anyone has experience with grinding or dremeling these tabs off the 997.2 intercoolers to better fit the 997.1 ducts?

Thanks,
Franc

 

After trimming the 997.1 ducts one can also trim the oem clips to reach around with a sharp knife. No need for zip ties, and no need to spend $ on 997.2 ducts.

 

I didn't and didn't use them. I did cut up existing duct though.

I did spend a lot of time evaluating the change of vertical and horizontal offset though.

 

 

 

Bill, I just wanted to cheer you on. Love what you're doing.

When I put 997.2 intercoolers on my car I was able to re-use 997.1 hoses. The connectors are (mostly) the same. I suffer from CRSD (Can't Remember "Stuff" disorder) so some of the finer parts may have been forgotten. One thing I do remember is that the 997.2 ductwork wasn't cheap. Hopefully the prices on that have come down!
Looks like we're in the the same general neighborhood, see you around.
