you may want to search some british and australian websites or forums for links to ca parts, as they more commonly mess with those over there. the CA with a stock turbo is pretty much an n/a vtec motor, without the vtec. they are not too torquey but they can be beasts if done right. they're pretty stout, if you have it maintained.
phase2motortrend.com has some CA parts i think. it's just not popular in the usa because of the sr20 obsession (plus CAs are really like a 2 year run of production or something - for DE)
Last I spoke with WAyne, he only carries pistons and maybe some old inventory. CA's are doge even to the jdm and aussies. most have Ganked the CA in favor of the SR. More Parts! best luck finding CA parts is from an engine importer with motorsets than come in with aftermarket parts. goodd luck i say. like trying to find a leg bone for a t rex.
