yes, he's in the same power ballpark, but down on trap speed because he's in a heavier Targa. Plus that nice sub woofer setup he added still plenty fast though!

Curious on how the tial tubes install. Come with directions?

How did you manage to get the oil and coolant lines free without damaging them?

991.two

Well I carefully pulled them away from the turbo, slight bending on most of them. It's a little scary as you don't want to damage the other end of the lines, especially the coolant line as it feeds into a plastic manifold up on top of the engine near the flywheel top. If you damage that I can't see any way to repair it without dropping the engine.
Right 4-5-6 side is easier than the left 1-2-3 side. I had to remove the Cat on that side along with the header to get to some of the oil lines on the turbo. The only way I will be able to install the new GST turbo on this side is to connect most all of the oil and coolant lines first (turbo will be just hanging there without Cat or header attached) because the header and Cat are in the way of getting to 2 of the connecting screw points. I will be attempting this today. I will have to remove the two studs off the turbo exhaust/header flange to install the header. This will be fun.....

I have not received the Tial tubes yet. They were not in stock at the ordering time, next week I hope. I'll post the install.

Awesome stuff. Both the work and documenting it. Very interesting to follow. Keep us posted. Good luck with the day.

I am a big DIY guy but you my friend are way more bold than I am. Respect.

If you dont mind sharing where you got the GTS turbos from? Been looking around for a while and unable to find decent pricing..

991.two

Just over a year ago Suncoast Porsche had a sale on the X51 kit for the 991.2 and I negotiated a deal for just the turbos and no software or installation. A few months later they put a hold on all X51 kits.

This is how I had to hang the 1-2-3 side turbo with just the oil & coolant lines. Because I had to bend out and away some of the lines they were harder to re-install. One of the oil line bends I did was not returning to it's original form and made it very difficult to get it back in place and flush. I removed the complete inner cooler to get a better working area. So 2 hours for one oil line install.




Oil lines made in France! Thats the hard one to get at ( T-30 Torx button head) when the intercooler hoses are above the turbo.




This is the take-off base turbo. Better photo of the hard one to get at. Oil line tube with o-ring fitting has to go in straight and I had put a bend in it so it was a bear.





Yes I made lots of room for myself to finish this one up.








Cat back on and now waiting for the Tial Intake Tubes.

991.two

The Tial inlet tubes arrived Friday afternoon. Install looks straight forward. 6 basic parts, no instructions, no problem.








Comparing the size of the stock tube with the Tial tube: 58mm O.D. and 3mm thick for the stock tube; 77mm O.D. and 2mm thick for the Tial tube. Should flow better.

Test fit one of the Tial's without the intercooler & cage to see a better picture of the path.







Removal of the intercooler cage with tubes is fairly simple. Loosening hose clamps at air filter and clamps on air pressure tube along with vacuum line from by-pass valve on inner cooler. A few nuts and screws around the cage.












Pull it off.








Removing the original tube fairly easy. Remove the by-pass valve from rubber grommet, then remove the grommet.








And the tube securing clip. You won't be using this clip with the new tube.








Now slide out the tube.




They look almost the same! Maybe not.

991.two

Tial's tube slides right in.




Install removed grommet into Tial's tube. Then by-pass vale.













Ready to put back into the empty space.




Both sides back in their space. Vacuum lines and hose clamps reconnected and tight.




Inner cooler air inlets back on.





Now install the wing assembly.








And wing wiring cable connector.





Bumper assembly and wire connectors. Then inner fender linings, tail lights and were done.

Great thread.

question: will the hot side of the 991.2 turbos always rust (surface rust) is that simply unavoidable?

porsche tells me yes, it is unavailable. they could replace the turbos and it would just rust again simply from moisture in the air.

I detail the car - including the underside - and that surface rust gets my ocd!
