ok thinking about this, JGSTools.com doesnot carry the CA18 exhaust flange so here is the deal, unless someone has access to measure the port spacing and port size fo the GA16, KA24, SR20 even the RB26 to see if they match up with the CA port size and spacing, we could buy just the flange from the GA or KA and cut and rotate the flange pieces to bolt onto the CA18 head (i think new holes may need to be drilled in the flange)
or even better if we can get an undrilled flange, cut it up, lign it up with the ports, so we can drill out our CA18 exhaust head bolt pattern into the flange pieces.
THEN just buy all the bends neccesary, isee that they have the "T" and 90* bends...
and the flanges needed -
I am thinking of getting one flange, 4x90* bends (two for the manifold and one for wastegate, and well one spare), 2x"T" (for cylinders 2&3 runners), radius plate for turbo, one T3 flange.
even thinking of getting the T3 turbine housing from a Grand National (same specs as my T3) just that i has a port for the Turbonetics Deltagate so that it bolts right up onto the turbine housing... that way i can use the three bolt flange for the manifold, and not need to port a wastegate off the log manifold, and get better flow from the manifold...
here is a pic of the GN T3 turbine housing from Turbonetics:
