I'm thinking about dropping 15k into my lly for some big power and ability to hold it. I need suggestions and advice.

Moved to other performance discussion.
How much power are you looking to make, and what's the purpose of the truck going to be?

As much as I can . I want I to be a sled pulling truck. its a 04.5 lly I have a s&b intake. 4 inch exauhst juice with attitude cts and fuel rail fittings.

I would spend about $4k of that on a transmission rebuild. Then look into some other items such as gauges, EFI Live and a fuel system to start. That will set you back about $6K +- some. This set-up will get you 500+. Then if you want to do a turbo and injector upgrade you could be above 600.

are you doing to daily driving the truck to? what class are you wanting to pull in?

to the OP, is your truck a automatic or manual? are you going to use it just for pulling or are you wanting to take it out on the streets? if u want "big" power im pretty sure your 15k can get you there, but...the stock internals wont beable to hold it for a long time with hooking it to a sled. on a side note: theres alot more to hooking to a sled than just having big HP numbers. your not only going to have to drop money into the engine/tranny, your going to have a weight bar, traction bars, good set of tires, etc etc etc and that can add up quick.

yea its still going to be a daily driver. Im not sure what class im a noob to all of this.

I would be tempted to do your own research first and then ask the questions. Seems like your asking more for a shopping list .

But as tyler says. Tranny is top of list then efilive and improvements to fuel system. force feed the CP3 with an airdog and probably a slightly improved CP3 to keep the fuel rails full of pressure.
