Topic: 21 ru motor

[mxjimm]

(YEA I FINISHED IT) i rebilt a 21ru toyota motor it was a pregnant dog getting parts but it was possible. I am finaly done it ttok me forever. And many hours of sweat and some bloody knuckles but it looks bad ass and is ready to go in the truck. ill let you all know how she runs when i get it in there.          

It is running great and im puting out like 145 hourses with it. it is so

wow... i have heard that motor is a complete turd, hopefully it works well for you....

[kneedownnate]

Why oh why would you "want" to build a 21ru??? 

[jimbo74]

65 hp is what i have heard


my 22r might be a dog, but i would rather have 95 hp over 65 anyday

[79coyotefrg]

according to my sources  the 21R-U  1982 to 86  was 105 hp

What was it in?  Is it a car motor?  Was it imported to the U.S.? 

[79coyotefrg]

it was a corolla /celica/pickup  in europe and asia

[kyle_22r]

they never put an R engine in the corolla, unfortunately.

the 21R-U is a japanese smogger engine.  they didn't use the 20R or 22R since they're both over 2.0l, which would mean every vehicle produced for sale there with those engines would've been taxed big time.  so they developed the 21RU, which is like a baby brother to those engines.  it's essentially a 20R with a tiny bore, same stroke i think.

  your right Kyle, sorry,  no corolla,  cressida is on the list, 

yep 21R-U 82-86 1972cc 105hp@5200  120@3600  84mm bore 89 stroke

Does anyone have a picture of one, does it look any different than a 22R

[79coyotefrg]

   beats me , never laid   on one

[kneedownnate]

It looks identical.  And 105 hp would hafta be at the crank.  They listed the old 18r @ 150 hp, so keep that in mind too.  I've had one of these and it was a complete turd, no power at all.  With 4.10s and 215/75-15s I couldn't even go 65 on the freeway unless it was dead flat, and it had good compression.  I don't wanna bag, but the only reason to run one of these is if you can't pony up the cash for a 22r.  A hybrid with toyota only parts will utterly embarass this engine.

[kyle_22r]

well, depends on the 18R also.  they weren't torque engines(had less stroke, only about 2.0l i think), but it was made in several configurations, most notably the 18R-G that made about 140hp, and often pushed much higher. better swap for a celica though, and kind of hard to find since it was never sold in the US.

the 18R-C that was sold in pickups and celicas here from '73-74 made about 100hp or so, but low on the torque.

I have a 21ru in my 85 toyota and it runs amazing. All the power I need. I run 37s with 4:11 gears and I can roast them on dry pavment. As far as Im concerned it out preforms the 22r that I pulled.

PICS or B.S.

Even if you ment to type 27's I call B.S.
