Stage 1 2300 kit here, upgraded injectors for safety and a DW400 + bap but I'm making 600 wheel on a mustang Dyno with conservative 93 Lund tune. You're going to be octane limited with 91 CA crap no matter which kit you get honestly. Intake and TB aren't going to help you much.
Stage 2 is not the gt350 tb. Before my current set up I also had the frpp2 tune. I plan on upgrading to bigger injectors and tune. I'd love to use my tb and cai from my frpp2 set up but most tuners rather tune for a different tb. Now that the weather has started to cool down, I'll hopefully be heading to the strip. On slicks I ran a 11.8@115mph with the frpp2 so I'm curious on what this 2300 stage 1 will do on the EB 93 tune. Relearning to launch and having to shift into 5th will not help. I'm just hoping to get a solid run to see what kind of mph I can get. Even if I don't master the launch and pull a 1.5 60' we should be able to figure out what my glory pass might be.
The spacer they reference can mount the GT350 style as well which is what it means.
That is the Ford Racing 90mm pictured.Right on, I thought that was a bit strange. Saw the GT350 throttle body in an install pdf. Must be old.
