I seen this ls1 intake for a cool price what you guys think?
I'd rather pay $350 for a 6.0L truck intake manifold, than use an LS1 intake manifold for free.
The MpG savings alone would pay for the truck intake manifold in a lil over a year, even without a fully enabled Aussie operating system.

Dang! Just threw one away a few months ago 'cause they were going for so little. :eek:

You'd have to be spending an awful lot on fuel if a 10% savings yielded $350. But it's possible.

Why not go with an LSA intake? fits under the cowl and stock hood. :ROFLMAO:

I posted it as a joke but in all seriusness, , an 04 6.0 will definitely handle an LSA blower at lower boost levels without any modifications to the motor itself. You will need to upgrade the fuel system with a pump, injectors and fuel pressure regulator capable of working with boost. Accessory drive, there are over a dozen options out there that work depending on your needs. At low boost numbers you can easily get away with the simple drives that run everything off a single serpentine belt with factory accessories. Plenty of people are running LSA blowers on stock 6.0's making in the low 500whp range without issues. TBH it's not all that difficult but definitely adds some cost and complication to the build at the added benefit of a ton more HP.

Just my opinion, but to me using one of these cheap-ish blowers is one of the main appeals to doing an LS swap in the first place. Most guys going through all the trouble to swap stock LS motors in aren't making more power than a heads/cam/refreshed bottom end LT1 would have made for the same cost and less labor time. The ease and cost of supercharging an LS though with one of these LSA blowers is a huge advantage over an LT1 though as many stock LS series engines can handle boost much better than a stock LT1, you have ECUs much more capable of being tuned effectively on boost and LSA blowers can be found for $2500 complete if you shop around. It was also a factory forced induction setup that is fairly reliable and self contained so you don't have to deal with half the headache you'd need to deal with when building a low cost turbo setup with welding up hot side/cold side piping, running oil lines, turbo mount, figuring out what waste gates and BOV's to use etc...

Hypereutectic pistons can "get away" with some boost at the 04 6.0's low 9.5:1 compression, but this is not really safe. Personally, I wouldn't have forced induction without (at least) swaping in some forged pistons. Yes I cracked a few hypereutectic pistons in my younger days. Chances are you paid next to nothing for the LQ4; show it some love with parts that can withstand forced induction. You know that after six months or so, you will be looking to spin that blower faster!

It is the rods not the pistons that cause the issues. The 04 may or may not have the Gen IV rods. You are safe up to 600.
I've broken more than a few hypereutectic pistons with forced induction games. Most recently, I experienced piston failures in two different LSA engines. Now days, I don't play with adding horsepower unless I am fully forged.

This is always a good rule of thumb: "If adding a power adder like nitrous, turbo, or supercharger, we recommend avoiding the use of a cast or hypereutectic piston."

People should take any risk they are comfortable with, but I can tell you that it is cheaper to build it right first; instead of breaking it and then building it right.
