So you are right, with good/proper supporting mods this is realistic.

Precision is also working on a new 6870 turbo. So, 68mm compressor but more importantly a 70mm turbine wheel. The turbo is rated at 1050HP, and I am going to do my absolute best to make this turbo work with the twin scroll kit. By the way, that HP rating translates to 105lbs/min of air coming out of that compressor.

The turbo however is not due out on the market till late this year...but it gives us something to look forward to. It also won't be available with a twin scroll turbine, but that should not be a big deal. It will still perform extremely well.

All the Precision turbos that come with this kit are billet wheel as well, so just like the new Garrett GTX line of turbos. These don't even start to shine till you get past 20psi of boost, so all the customers out there with these 6266's and 6766's even at 550-600whp are still a long way from really waking these turbos up.
