have a 1983 4x4 and got to build engine smokes bad . but im not sure what year model the engine is.and have noticed that the kits are for 82 - 84 models & then 85 up with the 85 ups easier to find. question is will the rings, bearings & gaskets for the 85 up kits fit if its an 82 - 84 block.or is their a way to find out for sure what model engine i have

 

Measure your deck height.

also look for the "laser" block id (see pic at bottom of LCE webpage)

1975 - 1980 20R Block
Deck Height 11.280"
Stock Bore 88.5mm - 3.484"
Maximum Over Bore 90.0mm - 3.544"

1981 - 1984 22R Block
Deck Height 11.280"
Stock Bore 92.0mm - 3.622"
Maximum Over Bore 93.0mm - 3.662"
Big Bore Forged Piston Kit 94.0mm - 3.701"

1985 - 1995 22R-22RE "Laser Block"
Deck Height 11.090"
Stock Bore 92.0mm - 3.622"
Maximum Over Bore 93.0mm - 3.6662"
Big Bore Forged Piston Kit 94.0mm - 3.701"


All Toyota 20R - 22R - 22RE engines use the same crankshaft and connecting rods. To accommodate the different deck heights, Toyota changed the compression height (piston pin location).

 

appreciate it Gov't Mule now i know my engine is a 84 or older now the question is will 85 model rings,rod & main bearings & gaskets fit the 84 & older blocks ?

 

I'd contact the guys at ENGNBLDR they should be able to set you up with all the right parts. Quality is great and prices are good, I've gotten a bunch of stuff for my 1st gens from them.
