Wheel to Wheel's $10,000 kit used stock mainfolds, passanger side flipped over then a custom crossover from the drivers, a lot of ppl criticized that seeing it is such a spendy kit. That price did include install and dyno tuning thou....and it made some really good power even on the 4.8L (see How To Build High Performance LS1 Engines for more info on the kit)

 

the 416/478 is that your rwhp and trq i have a 01 gmc sierra C3 6.o and a kenny bell twin screw but im getting a 408 built for mine right now would like to hear what u decide and how it does

 

yeah, those numbers are on a totally bone stock 6.0L, stock manifolds, everything.

 

The intake,rails,ect are neccessary to make efficient HP. Believe me,if Parish switched to these he would make more HP than he did at the same boost levels and could run more HP on the street without KR.(we just tested it on the same setup).

Jose will give good info on what Turbo stuff you need. Just keep in mind that putting a combo like this together will cost alot of $$ in labor.Looks to me like it is a 1.5-2 week job plus working out any bugs

 

Ouch

 

I'm with you on that. My point is how much do you need/want on the street. I have way more than is strictly necessary (and if anyone repeats that I said that I will deny it) for a street vehicle with the stock components and have absolutely no issues with KR.

Would I like my IATs to be lower than ambient? Sure!! But do I need it to go fast? Nope... I know my where my bottlenecks are, but they don't really impact what I want from the truck (unless someone wants to donate to the keep Erik off the couch fund, in which case, I need an intake, lines, sump tank, GT42-88 and a 90mm tb ).

 

everybody wants a 90

 

well, truth be told, I'd rather have the 42-88

 

I just bought a NW90mm tb. Now i need to get a vic jr, rails, and intake elbow. 1.5-2weeks labor? holy **** batman!!

 

i dont doubt i would make more power with all of those parts and they are on my list if i decide to push it past my current ~1000rwhp

i really think they are overkill and a waste of money for 750rwhp.
