Best bet for the 5EFHE is the Cynos and Sera (i think). Pretty hard to find, no doubt there will be a couple in Ireland lol. You also get Gen1 5EFEs in some Jap import Cynos, Sera etc which have fairly thick rods but not as thick as FHE, can still put decent boost through them. Most people get a 5E Paseo block & crank and forge it with a 4EFTE head bolted on. Could just run a normal 5E block from a Paseo (Gen2) with FTE head pretty safely aslong as you fire a set of bottom end bearings in it and obviously a new head gasket. The standard comp ratio is 9.6 - 1 on the 5EFE so youd want a thick headgasket like a 1.9mm or 2mm, to run decent boost, or use a thin 0.6mm headgasket and run less boost. Or put in 4EFTE pistons in the 5EFE block and run something like 1.4mm headgasket wirh 1 bar boost for example.
