Its still a Garrett turbo and turbine wheel. The burst constraints are still of the Garrett design on the compressor cover. Turbos direct (one of the largest Garrett turbo and tail distribution in north america) is the shop making these. They are well known in the drag racing community. I'm curious to see results also. I have held the turbos and examined them. I can say the machine work is better than other companies like precision turbos. If anyone wants to supply both the standard and billett 2560 I will be happy to instal and dyno both sets.
