The 2-valve SOHC 2.4 L (2366 cc) 22R was produced from 1981 through 1995.

In 1985, the engine was significantly reworked, output was up to 112 hp (84 kW) at 4600 rpm and 142 ft·lbf (192 N·m) at 3400 rpm. Many parts from the newer 22R-E are not compatible with those from the older pre-1985 engine. Non-compatible parts include the cylinder head, block, pistons and many of the associated parts such as the timing chain and cover, and water and oil pumps (although the oil pump internals are the same). These changes also affected the 22R, therefore one can consider the 85-95 22R-E as a fuel injected version of the 85-90 22R with only minor differences if any.
Toyota swapped the dual row timing chain used in older engines for a single row chain with plastic guides in 1983.

The turbocharged 22R-TE (sold from late 1985 through 1988) produced 135 hp (101 kW) at 4800 rpm and 173 ft·lbf (234 N·m) at 2800 rpm.
However, its weakness is high-end power.

in the '86 and later blocks were either 2MM taller or 2MM shorter..can't remember....LOL

other than that i believe your good......

however, it would be smart to get a 22RE or a shortblock out of an '89-95 truck...

I see no difference between the 83 and 89 22r block.

xxxtreme22r

there is almost a .20" difference in the deck height between a pre-85 and post '85 block. A pre-85 block also used domed pistons, while a post-85 used flat tops. This is why when doing a 20R/22R hybrid you have to use a pre-85 block with the 20R head. As a side note, because of the difference in deck height the pre-85 timing chain is shorter than a post-85. This will mean if using a post-85 head on a pre-85 block, you will have cam timing issues becuase of the difference in chain lengths. If the chain will even fit, never tried it though.

the block is almost indentical but the pre 85' 22r's have dual timing chains.

Ok to be more specific .........I have a 92 and found a 86 carb motor can I use the motor without pulling the head and still use my efi???

millionyota

Will my intake , exhaust manifold etc fit the carb engine?? No head swap etc...just the long block

Romans117

My understanding there is a difference in the heads.

How much is .20"? [ ] Less than the box?

camo31_10.50

you're not going to be able to "see" a difference in the heads with your naked eye...once you start measuring...then you'll see.

as far as I know......the heads are the same..

i know i was told i can take an EFI intake manifold and bolt it right up to my 22r head in my '86 pickup...and it has extra bolt holes in it that are not being used...probably for an EFI intake.

millionyota

have aNY OF YOU USED AN OLDER 22R IN A 22RE TRUCK???? FOR WHAT IM PAYING FOR THE MOTOR IT IS WORTH IT TO ME TO TRY IT BUT IM JUST TRYING TO GET EVERY BIT OF INPUT BEFORE I GO CRAZY ON IT....

millionyota

Thanks for all the great replies ...........so far

camo31_10.50

you can put any fuggin motor in there you want....lmao

a 22R carb'd motor WILL BOLT IN...and it WILL WORK FINE..

or you can pull your intake manifold (leave everything attached to it that you can) and just bolt it up to the 22R head....as long as the 22R is 1986 and up.

millionyota

Thank you camo that is what i wanted to see ......... Just didnt want to get so far and have to go make a huge parts run for stuff i wasnt expecting..i just started to get in to these things ....so im not a numb nut i am just a newbie ....i own alldata and still couldnt find the info and the gasket part #'s were different but i felt it would work but you never know

xxxtreme22r

.20" is almost a 1/4 inch, camo hes taking about the shortblock only not the whole motor. Yes the heads are the same the blocks are different. subtle but enough not to be a direct swap to an already established motor. I believe he will also need it's timing cover, timing set, oil pump etc. If you don't believe me look at the engnbldr site and see what fits and doesnt fit the 85-95, and the 81-82 and 83-84. 81-82 22rs are the ones with the dual row, 83 and 84 are single row. The only thing on his site he sells his heads for the 85-95 22r's. I wonder why???

Romans117

I am pretty sure I was told the EFI head would not work for a Carb setup. Here on yota tech. How about a pre 85 head working on a post 85 block? I am enjoying the thread.

xxxtreme22r

the only difference in the complete head from efi to carb I know of is the difference in the stock cam profiles. Now there are others like the fuel pump block off on the efi, timing gear spacer on the efi, and the lack of the fuel pump cam on the efi. But the bare head with valves etc is identical as far as I know of. Now if we are talking pre and post 85 heads I am not sure, maybe the exhaust port shapes?

Incorrect. Only '81, the first year for the 22r, had dual row T-chain
