Couldn't find a topic from searching, here or elsewhere. Just wondering if it's feasible to run a 4A-FE on the stock computer with the 9.4:1 4A-GE pistons & rods on the 4A-FE crank? FE crank is supposed to have 40mm rod journals, just like the early GE crank.
I'm guessing there might be problems with interference? I know that the GE piston dome & the FE combustion chamber don't have the same shape. I'm curious about this because sometime soon I will need to pull my motor & tranny/transfer case to change out the clutch / pp / resurface the flywheel. (I have a 4A-GE build slowly going at the moment, but I want to break in its clutch before the engine swap.) I have a set of bluetop pistons & rods sitting in a box. I could clean them up, get some new rings & bearings, and do a minor rebuild of the FE while it's out.
Crazy idea I know... it is 3am right now and I need to get some sleep. :lol: :ugh3:
Other thought is, I have a set of pistons (and bad/bent rods) from a 1997 4A-FE sitting in my garage. Could I throw those pistons onto the bluetop rods (same 18mm press-fit pin, I believe) into my 1988 4A-FE and see an increase in compression? I can't remember the reason for Toyota's redesign of the FE pistons for the '93-'97 years.
