Twin turbo upgrade

Me personally, I don't like the idea of machining stock turbos for $3500. Why aren't more people just bolting in aftermarket turbos?

Just believe us when we tell you that it isn't that simple on this platform. I would love to be able to just fab up a log manifold and slap a EFR on it and call it a day, but it isn't that easy.

A friend of mine here in Houston is designing a manifold to fit disco potatoes. You can read about it more on the other forum.

Its not impossble to do, its just the resources involved to do a literal Twin turbo upgrade in size is damn expensive.

More than likely you will have to upgrade the Intake, Wastegate, Downpipes, and Exhaust + tune which is extra $$$$$$ if you want it done correctly


Its coming, your just not going to like the price

Why don't you have a chat with Rob Beck and ask him how much time, money and research went I to getting
his set ready. Not to mention $3500 is nothing on a platform like this; especially given the noticeable gains.

Either way, GL!
