I have a 2006 Sierra RCSB with a 5.3 auto... truck ran a 15.0 stock with just a 40's flowmaster on it... want to get it into the 13's... i am going to get Pacesetter LT's with 2 1/2 pipeing going into dual flowmaster with a dyno tune. only want to use bolt ons no cams turbos or nos... possible?!?! if so let me know what i need to get... thanks

 

maybe possible, but you will need every possible bolt on.

bolt on's might get you there, but cam sure would make it easier

 

Fastest way for 13's is a good tune, spray that pig..

This boltons should put you high to mid 13's. K&N FIPK, ASP Crank Pulley, Pacesetter LT's, Full Single 3" Exhaust w/good flowing muffler or cutout, 3k T/C, 4.10's, Eaton Posi, build your tranny or at least get servo valves and shift kit, a good set of dragradials or 26" e/t streets and defenetly a good tune. Good luck.

 

A 3500+ rpm stall converter and all bolt ons, look into a free flow exhaust i.e. magnaflow, corsa, or borla. Flowmasters have that distinct sound but they can't give you the extra power that the better free-flowing exhausts can. My 2cents

 

cheapest and quickest way would be to spray it..takes a day to put on and you can buy a used nitrous kit for $350-$500 all day long...just a good torque converter is gonna cost that much..gears and a differential is gonna cost ya a close to a grand to get it and have some one do it..the under drive pully is gonna cost you around 200..the pacesetter un coated headers are 275 plus to have some one do a true dual will cost ya some where from 350-500+ denpending on the shop you have do it and what you have done and mufflers you get. a cold air intake are around 150..you can make one yourself alot cheaper.. you can also port your throttle body adds a little hp...dont get a mass air, throttle body spacer, or a bigger throttle body as they are all pointless with what your doing..

 

My 2000 rcsb went 13.9 couple weekends ago. This was full weight...upper 60's degree and high 80's%humidty.
Spinning out the hole hard and getting a little sideways on the 1-2 shift.
Mods are:cai,lt's,ory pipe,e-cutout,e-fans,ud pulley,od alt pulley,4.10 gears with eaton lsd.Also crap tuned by myself.

I agree spray is the easiest and cheapest way to get there.
