My 01 turbo would turn over then quit after a few seconds. Dealer is replacing my throttle body. Can you guys educate me on the Throttle body, and is there an upgrade for this part? thanks ritchie

 

The throttle body is a housing that regulates airflow to the intake manifold usually located between the air filter and the plenum

Yes, throttle body upgrades are available but stock should be fine

 

I thought u had a fuel problem

 

Yes, when I would start up, it would fire up normally and then konk out like it had no gas. The gas pedal was also dead. No CEL's. My dealer spent 2 days working on it, besides needing a throttle body, the DME also needs to be replaced. Can anyone theorize what went wrong

 

The OEM TT TB is 70 mm. The OEM NA 996 TB is 75 mm. Speed Gallery, EVO and IA, among others, offer the larger 75 mm TB for the TT. It is not a direct bolt-on. Rather, the y-pipe has to be modified and/or replaced. Speed Gallery offers the 75 mm TB along with an upgraded intake plenum -- it is an excellent mod.

hey craig, what is the approximate cost of the plenum upgrade

 

+/- $1,000 . . . for 35+ hp. IMHO, thats a great value. Call Speed Gallery for exact pricing.
