Anybody running the fast 102 rt on their 5.3 looking into doing and intake but dont want to do all the modifications to run an ls intake. thanx

 

its still a car style manifold so wont you still have to do all of the same modifications?

 

its still a car type manifold... so you still have to do the conversion.

unless you have a HUGE heads/cam/stall setup on a 5.3 its not going to give you the results youre hoping for... I'd do a 90mm on a 5.3 personally

 

The FAST lsxrt is a direct bolt on for the trucks (so they say...) but I believe you may have to run the fuel rail kit from fast also. Then depending on if your dbw or cable get a 90 or 92mm TB. Keep us posted if you get one. Call FAST to see exactly what you need.
