Just curious to know if anyone on here is using the JBA Cat Forward headers on LS1 F-body turbo build? I'm thinking about basing my kit around those. Let me know if you have or know someone that has run those headers. My biggest concern is with the clearance between the headers and the strut towers....all input is greatly appreciated....

Damn thats not a bad idea. I havent seen anyone try that. Then again, I dont see why it wouldnt work. Why not just use cheap truck manifolds, the gains between JBAs and manifolds on a turbo setup will be nominal.

 

I have used it. It does not Bolt on due to clearance to the steering shaft, but I modified one of the primaries to make it happen.

 

how much did you have to clearance the manifold? was it a pita? which primary got in the way?

 

its a header. The number 5 primarie I believe it was, hits the steering shaft.. but for your info, this was in a foward facing configuration.

 

yea I understand the forward facing idea but was actually clearancing it a pain in the ***?

 

ive been wondering this for a LONG time, seems like it would be a viable choice, especially since they arent very expensive at all

cheap alternative for a set of customs

 

these were the truck headers though right.

 

yes truck headers, hummer.

 

Exactly what I was thinking...I don't feel like fabricating my own so this seems like the reasonable way out of the extra work.....clearancing the one primary is a minimal amount of work.....

 

not clearancing but cutting and moving a primary.

 

I used them on a build. Had to cut and reweld one of the primaries to clear the steering shaft.

Not worth it IMO.

 

Happen to have pics of the work it entailed?

 

Just out of curiosity, what is your engine/turbo?

 

It was about 4 years ago that i did version 1.

In the process of building version 2.

Same pipe dream everyone has, ie. AC. no relocation of alternator. Stock K member. Etc.

I have the design. Looks like i should be able to do it.
