I recently finished fabrication/installation of my turbo system on my slant. The rest of the motor is stock and I am using a small air research T3 running 7psi of boost.

I could use some help setting up the carb. My car is a 75 dart sport, and the carb is the holley 1945 single barrel. I have the floats but am wondering if someone could recommend a jet size that would make a good starting point.

I myself have very little understanding of carb jetting, so my mechanic will perform all the adjustments, but he thought I should see what others had to say regarding, the jetting. Also any advice concerning timing would also be appreciated thanks

i don`t have any exsperience with turbo`s but i would go 4 sizes up on the jet and keep total timing in the 12/15degs range and use champion 9y`s or r5674-6 ngk or 274 accel, to start with maybe colder if you start hurting plugs. if you have the peanut plug head then use rv9yc champion, br6fs ngk or 262 accels.
