My 05 rcsb has an LQ9 and trans outta a VMAX truck in it with OBX Coated lt's, k&n cai, 160* thermo, custom tune, dual exhaust with one muffler dumped under cab, and plugs/msd wires. It has factory e-fans. I'm bored with the power lol, and I've never torn down a motor. What can I do to make it faster without getting into the motor? Are there any bolt-ons worth the trouble left?

 

take the bed off. that'll make it faster.

Underdrive pulley. STS kit. Radix. N20. Lighter wheels. Ported TB for better response. FAST intake.

to name a few.

 

I think you've pretty much maxed it out. Stuff like UD pulley is not worthwhile in my mind. You can add something like a tr224 cam and gain a solid amount of power.....probably end up about 380-390rwhp. And then a set of heads ...I was told the prc heads I ordered will add 30-35rwhp

 

Fi.......

 

Ok, looks like I need to find someone to install a cam for me now! Haha, modding is an addiction!

 

a shift kit, servos, and a higher stall TC will make it much more fun to drive....

 

...add a cam matched to the converter and some good heads and you'll have a real fun ride
