Yes there are fwd ca18det, I got one, I have 87 pulsar which I installed a fwd ca18det, they came in the blue bird in Japan, 87-88 they came none intercooled this is the first generation of the ca18det and in 89-91 they came top mount intercooled, I got both engines, and the top mount intercooled ca18det has about 25hp more plus it is built tougher at the bottom end, it has a crank inforced thick piece of metal which it goes parrall under the crank, while the none intercooler it doesn't have this piece also the none intercooled engine has the intake looks exactly the same as an north american pulsar which it extends over the valve cover.
