Im in no big hurry so I can wait. I just really like your new cast manifold and the one piece downpipe design. Very clean looking setup.

 

The 3.5 will be a 2 pc design. Easy fit higher flowing no cut and welding ony part. That's a plus. Just add a band clamp in the middle. .
Should have them done in a few weeks.

 

Do you have any idea how the crossover flange inlet on the back side lands in comparison to a stock truck manifold outlet ( closer to the block, farther, shorter distance from the back cylinder or closer etc... ) ? I am installing a LS3 into a 63 nova with an aftermarket front clip on it, and I would like to see if I can get a stock truck manifold on the passenger side to see if I should even bother trying to order one of these to fit it up. I will have the motor in the car next week and can try to fit my stock passenger manifold then. Also, will you still offer your last generation manifolds if I want to buy one that I can cut and modify if I have to?

 

Sorry no real comparison. I can take some pics for you of the turbo manifold.

 

someone is ordering a kit very soon

 

Very slick trick!!

 

Great to read .

Thanks.

 

Looks good I may just do this instead of fabbing up my own front crossover setup. Will the crossover fit a NNBS 4x4? What are guys doing for the upstream O2S? If I understood right you are offering turbo manifold, cross over and down pipe for 1500? Looking forward to more pictures

 

Fits 4x4 fine.
Up stream o2?
Yes 1500.00 plus freight.

Should have some more pics up soon.

 

I have a mail order tune so I wasnt sure if they use Narrow band oxygen sensors on a turbo setup and if your kit had a provision for them. From your answer I am guessing they are done away with like the downs stream o2 sensors when I installed my long tubes.
