Chad what kind of fuel system are you using? Did you go for extra injectors?

 

Are those pictured GT3 heads street or GT3R's? Those intake ports look excellent. Did you reshape the combustion chamber or lower the compression ratio? What turbo will you use?

 

EL750,

I started with added injectors and ended with larger injectors.

 

ebaker,
picture shows street GT-3 and modified TT. New valves are 36mm and 41.5 from nimonic steel compared to 32mm and 37mm stock. Haven't told me about any chamber/compres changes. Turbos will use 48mm titanium wheel.

 

Does TTP build the Gemballa cars as well? I seem to remember hearing that.

 

KPV,

I don't think this is true anymore. Though there is a lot of cooperation among German tuners.

 

Damn nice work. Can you give us a ballpark on cost for the project?

 

Colorchange,


I'll let you know when I get the bill. Has to be up there though. A lot of custom work being done.

 

EL750,

I can't view the pics, must be something to do with my firewall. I used different material valves also due to exhaust heat temperatures. The stock turbo heads have a valve size of 32 and 37 mm's. The Cup heads have a valve size of 35.5 and 41 mm's. The GT3R heads have a valve size of 36.4 and 42.0 mm. I would really be interested if they started with turbo or Cup heads.

 

cjv,

Don't know how to auto load the pics here.
I know that he has both cup and also modified mine as well. This is what i was told over the phone. Kinda tuft when you are so far away from project. I asked about block thickness between valves where you experience the highest temp. differential and said that it is strong enough. Comments welcome.
