I am looking for the archive for installing the pyro (the right way) in the manifold maybe some pictures or some tips I have the guage sitting in my garage collecting dust. Also where's the best place to buy a 16 cm turbo housing for my 93. I am starting to do a lot of really heavy towing and I wonder if the 16cm is the right number. Just got the jake brake installed don't know how I ever towed without it.
