how thick are the cylinder walls of the 7A? aren't they the same spacing as a 4A?
maybe just do a quick calc to see what bore and stroke would be required?
4A is 81/77
7A is 81/85.5
the wiki mythical 9A says
and wiki is never wrong or edited by ppl with little ideaA modified version of the 7a that brings the displacement up to or near 2.0L, done by further increasing the stroke and bore with either a custom crankshaft and/or adapting a 1ZZ or 2ZZ crankshaft using a 81mm 82mm or 83mm bore selection anything past 83mm will require the block to have pressed in liner sleeves. The method to reach 1990cc's is to have a 83mm bore with the 1zzfe 91.5mm stroke, both the 1zzfe and the 7afe crankshafts share the same main journal diameter and have almost identical bore spacing ,2zzge rods are almost perfect rods to used in conjuction with ca18det pistons this is a proven low budget stoker option with very little machine work.
but sure it might be good. for a stroker or turbo motor
