How to Install Functional GT2 Nose Conversion on 996tt

February 5th, 2009 Comments off

We recently installed a GT2 bumper on our Camo 996tt Project. This conversion appears to be fairly straight forward, however as others have experienced there are a few hiccups here and there that may give you headaches. I spent many hours trying to find the best solution for these particular headaches and decided it was time to do a proper write-up on a functional GT2 Nose conversion. I skipped the details on how to remove and re-install the bumper cover itself as these have been covered previously and is pretty much straight forward.

It is always a good idea to test fit everything prior to painting the cover itself. Once you have the bumper painted use the 25 Speed clips to secure the black trim pieces on the center, right and left side. This is pretty straight forward, just mount the trim panels to the inside of the bumper and slide the speed clips on the plastic tabs to tightly hold these in place. These interior trim panels will line up with the newly added radiator shrouds on all 3 radiators when you go to install the bumper cover onto the car. The center grille attaches using 6 Allen screws and bolts which I ordered from Porsche. The lower lip clips into place and is secured on each side by a screw and clip. Once you’ve completed these steps the bumper itself should be ready to be re-installed onto the car, you just need to prepare the car for the bumper.

The biggest problem with this conversion lies with the center radiator. The GT2 features a tilted center radiator allowing the airflow to enter in the center and evacuate up through the grille which is added in front of the hood. It sounds straight forward, however do to the difference in cooling systems between the GT2 and 996 there is some custom modifications require. Be prepared to spill coolant all over the floor and yourself, but it’s all part of the gain (it’s a good idea to drain the coolant system as much as possible prior but you’re still going to spill quite a bit with the removal of the radiator).

Start off by removing the 996tt lower radiator brackets and replacing them with the GT2 counterparts. You will want to loosen then up, pop the clips off the radiators and press hard against one side to get the radiator out of the original bracket. It’s a bit tricky and will take you a bit of time, but it’s just the start of what’s to come. Holding the brackets up side by side you will notice that the GT2 units are nearly identical except for the angle on the lower mount, this gives you the pitch you need to make the radiator functional). While you have the brackets out, it’s a good idea to move the horns as well, we removed the front horn and bent the bracket to allow enough room for our re-routed hoses to fit nicely in their place).

The new shroud for the GT2 requires the radiator to be flipped. Flip the radiator over and install both the new interior ducting and front air duct as well (this is pretty straight forward as just 2 metal strips hold the front duct on, and 2 clips and 3 plastic tabs hold the air duct in place).

There will be 2 metal spacers needed behind the shroud to properly space the mounting brackets out, this will space the 996tt upper and lower surround brackets out enough to make them work with a bit of tweaking). Using M8x16x80mm bolts (check Ace hardware for these cheap) attach the upper radiator bracket through the frame, through the spacer (which is inserted inside the interior shroud) and into the mounting point on the car). This should line up the radiator just as you need but will leave quite a gap between your hoses and the radiator

As a result of the different cooling systems, we needed to make modified coolant hoses to make this work. The factory hoses where pretty cheap (under $15 each I believe) so we ordered 2 new ones from Porsche. Our plan was to cut the factory ends off the original hoses, use a 1.0″ hose connector and some worm clamps to attach the new hose pieces we bought to the exposed hoses on the car. This takes a bit of patience and mocking up on the car, but after a few tries and cuts to each hose you will end up with a path that works. Clamp the new hose onto the extensions, the extensions to the existing hose coming from the car, and the connectors should bridge the cap to the now flipped radiator.

Once you have the center radiators fabricated up and the hoses connect, it should be pretty straight forward from here as far installing the GT2 bumper just as the original one came off. Using OEM parts it should make for a very easy conversion, I’d expect 7-8 hours for the install if you have all the parts lined up and ready to go (which we didn’t as a complete parts list wasn’t something readily available previously). I also want to thank Stevem Russell @ Suncoast Porsche for helping me throughout the process with multiple parts shipments. They’ve got the best prices on OEM parts if you’re looking to do this conversion I’d suggest giving Steven and the gang at Suncoast a call.

More Updates to Project 996tt : KW Clubsports and OMP Velocita Steering Wheel.

February 4th, 2009 1 comment

We received our KW Clubsport suspension which will be installed tomorrow before going for a nice alignment courtesy of master tech Jim at Porsche Orlando. KW is a leader in coilover suspensions and is the OEM unit found on the Viper ACR. KW was out of stock in the US but overnighted these in from Germany to make sure we’d have them in time for our busy next few weeks of events. I can’t wait to get some time out on the track to get these dialed in and really put the car to work.

We also received our OMP Velocita Steering Wheel and Lifeline quick release hub. We’ll be installing a GMG rollbar in the car, as well as a set of Status racing new 5 point harnesses and racing setas in the coming weeks. We don’t plan on daily driving the car, so by installing the wheel we where able shed some weight and get rid of the airbag (which won’t do us much good once fastened securely in our harnesses).

You may also notice that the radio is torn appart, gone is the OEM Navigation which hasn’t received updates since 01, and in it’s place will go Sony’s newest single Din player the CDX-GT930UI. This radio has everything we need all in one compact unit, allowing us to enjoy our tunes and save weight. A rear USB Port allows for easy iPod adaptivity so we will always have some much needed tunes on our way to the local race track. I’ll post some pictures of the unit once we get done installing it later this week. In place of the factory navigation screen we will be mounting 2 Titan Wideband gauges to monitor each bank as well as a Greddy Profec B boost controller to keep a close eye on our boost levels.

A Sign of the Times

December 15th, 2008 1 comment

With the PRI show in Orlando this past week, we had the pleasure of hosting an open house for the great vendors who serve Titan Motorsports. The open house was hosted at our new location which is currently under construction on Boggy Creek Road, and displayed a handful of street and race cars. This state of the art 25,000sq/ft facility is being designed and built from the ground up with extensive planning to ensure growth for each of Titans divisions for many years to come.

The exterior shell has been complete for some time, however permitting for the interior buildup has held up construction progress. As these conflicts are now resolved, we are getting much closer to moving to our new home, and look forward to posting many more updates as construction continues. Our current expectations anticipate a smooth transition towards the end of quarter 1 in 2009.

We reached a major milestone in construction this week with the hanging of our massive new sign. The sign features 42” tall brushed aluminum letters which are backlit by thousands of amber LEDs. A big thank you to Nick and the crew at Diamond Electric for creating such a master piece and having it hung in time for our open house.
