Farley brought this project to me after I myself was looking for a turbo upgrade for this engine platform. I got in touch with Farley after I saw a post of him trying to find someone to build him a upgrade. He brought a set of used turbos to me to see what I could do. My setup is not a copy. I have been engineering my setup for the last 6 months. I have created many hybrid turbo upgrades for my clients including ones for the Nissan GTR, Porsche Turbo, Audi A4, and most recently the Bentley Continental GT just to name a few.

The additional 50hp will come from non generic mitsubishi parts. We have the ability to create our own custom billet wheels. This is something we will be developing after we have tested our prototypes and have a baseline. We have CAD engineered the programs for this billet upgrade to be as efficient as possible, thus resulting in the additional power.

Again, the RB turbos are a fantastic upgrade that has proved itself. Im not taking anything anyway from them.
I'm very interested in this upgrade.

These prototypes do not include the billet wheel upgrades. That is for future developments. Im keeping my measurements under wraps for now until we release the dyno and performance number for them. As for pricing, The RB turbos are very competitive. There is alot more machining that goes into these than people may even realize. Its not as easy as fitting new components into the stock housings. First the housings have to be machined to fit the wheels, Second the cartridges have to be machined to fit the housing openings, Third, The wastegate issues with materials and sizing. Forth, the cartridges have to be modified to accept the stock plumbing. Fifth, The turbine housing v band is not physically big enough to fit the new cartridge and turbine wheel, so a special v band flange has to be created and adapted to the housing. Sixth, the tooling. Special jigs have to be created in order to support the manifold/turbing housing correctly so that machining is precise.

Like I said, a lot more work than people think there is. Most hybrids include clipping the turbine wheel for more flow and upgrading the compressor wheel. This wont suffice in this application. All components are either modified or new. The easiest part is machining the compressor housing.

i posted over a year ago that i really believe that this engine can make 600whp, given the right parts and tuning.. and reliable horsepower too ..

another jump of 85-90whp is inevitable... i wish all you future space shuttle pilots good luck
