Thanks for the info!!
I assume the 1985 Toyota 4x4 trucks came wih the EFI if it was a SR5.
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
Truck/4Runner same, aka 2nd Gen for truck and 1st Gen for Runner. 22R, 22RE, 22RET & 3.0L V6(V6 in 1988)
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.
