I ask, because at the moment im talking with lots of turbo builders for this particular engine..and everyone's thoughts are on very far ends of the spectrum. It would be nice to know that someone out there is trying to build a purchasable turbo kit, built, priced, and proven for the average blue collar Joe, which the FRS-BRZ target market was originally made for.
Id be a shame to see shops miss the mark on this car because its easy to get caught up on the idea that customers want POWER and they will pay a premium for it. When i fear this isn't the case for this particular car.
Anyway, keep up the good work! cant wait to see more pictures, especially your chosen turbo location and compressor outlet clocking solution.

The turbo in the picture is a Garret GT28R. Its considered to be the "Disco Potato" line. If this turns out to be to laggy i'll switch to something smaller. In this particular size we can upgrade from 350hp capable to nearly 450hp with some of the new GTX lined turbos. However I believe that the standard GT will work far better at lower boosts than the GTX line. Same as the EFR stuff. Just requires you to work them to hard to get the results. I don't think this kit will be to far out of reach. I'm going to use the stock header. So no crazy expenditures there. I'm planning on fitting this behind the engine. Front mount intercooler is only up to 350hp at this time w/out cutting. Sure we'll make larger turbo kits, but I dont think this car needs more than 350hp. Its 160hp now and a blast to drive. I can't imagine what doubling the power to the ground will be and having a flatter torque curve from 3k-4k and rising on up. It will be some sort of a monster. We have 130-140ft lbs now peak. And no where near that in the torque valley. We should be able to get north of 200ftlbs in the valley I would think.
Now for those people who want 600hp, No problem, I can do this all the same, but we need to start somewhere and figure out whats going to work reliably for the time being.
