This is the older design with the catch can. I do have a Accufab TB that goes with it. Blower will come with the 2.75" pullie. Price is $2200 for blower with TB shipped. Blower was gone through at KB and had the snout rebuilt 10 months ago so there is no issues with blower. I went 10.94 skiping 2nd gear(auto and stock shifter sucks) at the track and 1.70 60 foot.
