87 or 88 i think cause my 86 had a carb, but it depends on the model

1985. depeneding on how a 4-runner was equipped(SR5's) came fuel injected. lower priced models got the 22R. turbo models were EFI as well. trucks were the same way.an 85 SR5 usually came EFI,but not always. also,alot depended on where the truck came from. there were no japanese built SR5 pickups built until 1989. the way to distinguish jap built,and american assembled trucks is the bed. USA assembled has the smooth side bed,with no rolled lip up top. all jap built trucks have the rolled-lip top bed. and,you won't find any of the jap built trucks with the 22R-E EFI engine in them. that was started on this side of the ocean.

NO.


I'll try to help as I'm a die hard Toyota nut and employee

1985 was the first year EFI was avaiable in 4x4 trucks. So from '85 through '88 it was optional, EFI or carbed... SR5 doesn't make a difference, that's just an package with mostly decals on body and a optional tachometer in gauge cluster.

It wasn't untill 1989 before it was standard in 4x4's, aka 3rd GEN.

ALL 4Runners are EFI'ed(22RE) although the very, very rare '84s might be carbed... 4Runners started in '85. Yet you might find a rare '84 if you search hard enough.

4Runners in '86, '87 and few '88s had the Turbo option, 22RE-T. In the 4Runners the Turbo'ed ones have an Automatic tranny. Digital guage cluster.

Turbo'ed Trucks(same year range) came with a 5-speed <-- very sought after tranny due to lower first gear and super tough. Digital Guage cluster.

In 1988 the 3.0L V6 came out.... has a bad rap but it's a good engine. Mine has 282K on it Although my 22R Toyota has 335K


Body styles:

1984-1988 - Truck/4Runner same, aka 2nd Gen for truck and 1st Gen for Runner. 22R, 22RE, 22RET & 3.0L V6(V6 in 1988)
1989-1995 - 3rd Gen Truck and 2nd Gen Runners..22RE's & 3.0L V6
1995.5- now - Taco's and 4Runners. Few 2.4L, mostly 2.7L. 3.4L V6.

They arent all that rare. My brother had one, a guy up the street has one, and I saw a few in the paper when I was hunting down my 1st gen. All 84 4Runners were carbed.
