So far neither of those posts are "proof."

"We're gonna" is not "We did." But I'm hopeful.

Gotta pay to play. A turbo isn't a big deal, but you have to upgrade other goodies around. A clutch is also on the list.

Send a message via AIM to 335 oClock
... if anybody wants a turbo upgrade - go buy a turbo, get custom manifold and other parts, and have a turbo upgrade.

I hope you all know you could upgrade your turbo without waiting for somebody to go make it for you

I know I said it before but I'm just affaid it will not be a bigger twin scroll setup - just a big ass turbo instead. Which will result in very significant lag. The current setup, while not strong up top is an absolute joy in the lower rpm range.

You guys are missing a lot of the important things!!! If you weld a big turbo and thats it, please explain to me how the hell are you going to tune it!!!!

The turbo that we need for a big turbo upgrade has to have a internal wastegate, because non of the tunes aveilable have the capacity to control an aftermarket wastgate. Second of all there is not that much space were the turbo goes.
Third the size has to be bigger but not to big since then we will have a shit load of hp only for 1000 rpms. And some one with 1/2 the horsepower will kick our ass

I have been working on a bigturbo upgrade for a while, and its not that easy. Lets see what they come up with.

borg offers a turbo with an internal wastegate and the procede can already be self tuned.
