Can i bolt FI to my '85 22R?
« on: Sep 02, 2004, 10:03:29 PM »
I have access to a '87 22RE 4x4 truck, motor's not running cause of something internal, Can I take all the computer and fuel injection stuff and just trade it over to my freshly rebuilt 22R carb'd?

I know i'd have to swap tanks and everything, just wondering if the 22R carb'd motors react ok to just slapping on FI. I'm sure there's a difference in cams or something.

The '87 I have is complete, so any parts i'd need for the swap are there. Just wondering what all i'd need to do, and if the motor would run just fine.

Thanks, D.

well the only diff is the intake valves are a tiny bit smaller and it is not reccomened to do by shops but it will work any way. :thumbs:

I don't know about the cams, but the cylinder head on your '85 22R is the same cylinder head as on the '87 22RE.  You should be able to see unused bolt holes along the top of the intake manifold mounting face on the head of your '85 22R. Those are for the fuel rail on 22RE's, which carbureted 22R's don't have. Toyota made one head for the 22R/RE motors starting in late 1984.

I'm in the same boat as you, I've got a dead 1992 22RE sitting on an engine stand and a 1986 22R in my '84 pickup. I've often thought it would be easiest to pull the head from the 22RE with the intake and exhaust manifolds attached and just drop them onto my R motor.  You will need a knock sensor mounted on your block too.  It goes on the block back behind  the oil filter. My 86 22R has a boss on the block where it goes, but I can't tell if it is threaded or needs to be drilled and tapped. There is also a fuel damper for the EFI bolted on the block right behind that.

My 1992  motor  is just sitting though, because I've decided that I'm not putting the energy and resources into any 22R/RE upgrades. I'm going to put a Supra 7M-GE in my SR5 xtra cab truck instead.
