Fisrtly is Bob so sexy he is distracting you from reading? lol!

Exhaust manifold - Some were standard exhuast manifold with a J pipe curling back up towards the front to mount the turbo and some were hand made extracter style manifolds!

The extracter style manifolds caused the turbo to spool up about 1000 rpm earlier!
But it was found that for street use the J pipe was better as the exhaust gases had a chance to cool down a bit before it got to the turbo! and this reduced the amount of heatsoak the turbine housing induced to the compresser housing! Over all reducing the compressed inlet charge dramatically!
( Not as important on a drag car as they only do 1/4 mile then shut the engine down! )
In theroy if a longer extracter manifold was made it would give the same benifits to a street car as a J pipe manifold, maybe even a little bit better!

Intake - A simplle hat was made for the carbie using about 2 inches of 3 inch exhaust pipe fitted with a top and bottom!
The bottom side having a hole the same size as the top of the carbie! and a rubber ring was attached to this to seal the boost! ( the rubber ring is the same as on the factory air cleaner or we were getting them off of Ford Laser air cleaners!)
The top side had a single hole drilled into it so that it mounted the same as a standard air cleaner!
From the side of this hat a piece of exhaust pipe the same size as the intercooler outlet was welded on and then the rest of the piping was connected to this!!

Hope this answers your questions mate!
