Which exhaust manifolds work on a 3rd gen with ls1?
Also, which K member has the most clearance?

 

are you asking what manifolds will work to flip around to use for a turbo system? I think the truck manifolds stick to far out and will hit the frame. Maybe stock manifolds. A tubular K member is gonna have more clearance the stock.. A lot more.

 

Yes I am asking which stock manifolds work, I thought I read somewhere that GTO manifolds work.. I know aftermarket ones have more clearance, I was more or less asking which one has the most.

 

I can say with 100% certainty that truck manifolds will fit and work. There is some clearancing and such that you will have to do though. I have seen the completed kit with my own eyes and it looked amazing.

 

I can second that truck manifolds will fit BUT I dont know how in the hell you could ever run a decent exhaust passed the engine without a tubular K so consider that a "must have" for this kind of build. Also the inlet ( TB intake piping ) requires some mighty fancy routing and/or mods to the rad support and rad mounting if you want to run an intercooler. Good luck

 

Anyone try C6 Manifolds?

 

C5, C6, GTO manifolds all are center exit which is exactly where your K-member is. They are also rather long so inverting them would put them through the hood

Camaro LS3 manifolds look promising

The C6 LS3 manifolds do look like they may work. I really would like to retain A/C. With those manifolds it just might.

 

I'm in the process of Redoing my IROCBOOST from the STS setup and stock LS1 to a built 6.0 and a front mount turbo setup. I have truck manifolds, 98 manifolds, 2001 manifolds, and a set of hugger LS headers i might just have to chop up to make fit. I'll let you guys know what i can make fit. When i tried before the truck manis hit the stupid big *** steeering knuckle...

 

Keep us posted for sure! A lot of people cut the flange off and weld on a V-Band. Worth a shot?
