I have a Cotton's BB 61 Turbo for sale.It has the built in filtering adaptor,The 4" inlet and 2.5" outlet polished housing, .63 exhaust housing. The turbo spools like mad with just a 2800 9/11.It's 8 months old with 1,100 miles. The car is put up for the winter so the turbo is still on the car. I,m asking 1,000 with the Actuator and 900.00 wtih out. I'll pay shipping. Thanks Curtis. 706-564-8900
