well searching for exhaust manifolds i found this link, looks like a good top mount probably for a T25 (hopefully T3)
anyone ever hear of them of seen their product??
well i emailed them so hope fully they will respond soon... but shipping will be expensive i guess..

also found a place called
http://horsepowerinabox.com that sells allot of CA18DET parts from cams to headgaskets etc... BUT most of all HEAD STUDS made by high tensil steel and ARP bolts and fasteners...
CA18DET S13 horsepowerinabox.com link
also found an intake manifold on their site too:
and a whole bunch of clutches and lightened flywheels etc..
