Those are reall nice turbos, but have safe power capability of 1360 hp! That is way more then most will ever use. The downside to running a turbo that is too large is you typically lose efficiency in the airflow range your engine is requiring. They will also spool slower then a smaller turbo. Those turbos probably have a t4 turbine housing and most likely are a p-trim turbine shaft.You want a T4 housing. He really did not give a ton of info. Those turbos would be best on a real large motor due to the large A/R ratio on the housing. The A/R on a ls1 twin setup should be no larger then .69 AR on the turbine side. A 60-1 HI-FI is a wonderful T4 based turbo that is amazing to about 1000-1100 hp. I would buy through someone like precision or innovative. They use Garrett parts to make a superior turbo.
