Hey folks, came across a '78 FJ40 2F engine that I could swap into my '84 FJ60 (see my build thread for more background on why). I'd be keeping my original 4-speed and transfer case. Been digging quite a bit through MUD and have a few questions and thoughts on how well this swap will work out. Trying to decide if should go for this, or hold out for a 2F out of a FJ60 for the rig.
Looks like the two main differences people talk about between the '78 and '84 2Fs are:
So my questions...
Looks like the two main differences people talk about between the '78 and '84 2Fs are:
- Switch from "domed" pistons with larger combustion chamber in the head pre-07/80, to "flat-topped" pistons with smaller chamber head. Don't want to use the wrong head with
- What are the pros/cons of each setup? I read somewhere the earlier engines make less power (they appear rated the same 135hp/210lb-ft) but are less reliable, is that true?
- If the older "domed" pistons are worse, I might just wait for a more powerful post-07/80 engine.
- Tapped holes missing from the block for power steering pump; that only came in '79 (found pics at power steering pump mounting advice)
- I need to check if this 2F has that or not. But it also comes with a nice power steering pump so maybe it doesn't even matter since it's mounted somehow, I'm thinking...
So my questions...
- Any other big differences I should be on the lookout for?
- How many accessories could come over? In general the distributor, headers, power steering pump, etc look better on the FJ40 2F so I'd like to use them wherever possible. Either way I'm going to keep all the emissions equipment since I still need to comply with Cali smog.
