Anyone familiar with the Toyota Motorhomes?

[swimbikerun247]

I'm looking at doing a rebuild in my 1986 4Runner. Instead of pulling the 22RE out of the 86 and rebuilding it, I'm considering pulling a 22R out of an 83 Toyota Motorhome. I've read that the motorhome motors produced quite a few more HP but I'm a little confused, is this correct? Can anyone explain the differences between the motorhome motor and the 4runner motor besides fuel injection?

The R produces 97hp, the RE produces 105hp. Google the specs for each to compare. The R and RE are the same except for the fuel injection head. You can use the 22R block to replace the 22RE block, they should be the same. If you are looking for more power than you should put an aftermarket performance cam shaft in it when you rebuild the motor. Hope this helps.

It's just my opinion but after doing my own research, I found that in relation to dollar per HP these engines are simply not worth the investment beyond a proper rebuild and perhaps some modifications to enhance reliability (and maybe choosing power-enhancing components for those parts that need to be replaced anyway). In be honest though, I would likely opt to swap my 22RE out for something else if it came down to it. For now, I just accept it for what it is. .....a good motor that is relatively gutless. My T4R is not my daily driver so I guess it might be easier for me to say I'm ok with it the way it is.

I don't understand why everyone thinks the 22re is a gutless wonder! I can literally get my truck sideways around a corner if I pound on it in 1st and 2nd, and I have 35's with 4.88 gearing.

Granted, my motor has been rebuilt with OEM parts and has an "rv" cam, as well as some next gen (ie., 89+) intake and throttle body parts, but its no race-prepped engine at all!

I can hold 90+ all day long with it, and in ID, we have 80mph speed limits, I normally push it up to 85 for extended periods.

Perhaps its because its the xtra cab truck and it doesn't have a few hundred pound shell on the back? I dunno, but it keeps up with traffic just fine.

I have a feeling most folks are expecting a lot more out of their 4runners because they drive vehicles that are much more powerful, say a '69 charger or newer r/t challenger? Maybe that's where I'm going wrong here, as I daily an '11 4runner and not the '85 supra since I blew the motor up in it!

Or, maybe its because my engine is in great shape with less than 50k on the engine, yet the majority of owners with 22re's have well over 200k on the odometer with minimal servicing?

I can say this, with just a few mods on a GOOD, SOLID-RUNNING engine, you can make 140+hp for very little money, and the 22re is an incredibly stout engine that's capable of taking a LOT of abuse with no issues. Its much cheaper to throw a few hundred bucks at a 22re than a few grand to swap in a 5vze or 1uz, but if you must have the extra 50-100 horses, then ya gotta pay to play!

Well, I did say "relatively gutless" which IMO/IME it is. ....and that's not comparing to either my Challenger or my Charger. I'm talking in general. Heck, I think my NA Forester is sometimes lacking a bit with 175 hp but never to the point where it was an issue (where i had to think about it).

Compared to my '86 T4R on the other hand, I have to make a conscious effort when merging into traffic, entering freeways from a short onramp, etc. ....forget passing in most cases. Having said that, it is still driveable but 115 HP is 115 HP and with a ~4800 GVWR (IIRC), that is a lot of weight for that engine to be hauling around. ....that just about 200 # shy of my Challenger.

I just accept it for what it is.

EDIT: btw, my 4Runner has about 90k on the clock and a relatively new, rebuilt motor (cracked block on the original). Its in excellent shape I'm happy to say. :
