Hello
I have an 87 4 Runner with a blown/cracked 21R-U motor. I know that the questions has been asked many times but what is my easiest motor swap option. I know the 22RE is probably the easiest for plug and go but not sure if their was any adjustment needed to put in the 21 R-U. Thanks.

 

Go chevy 4.3 carb. 3 wires man, 3 wires... I however went 4.3 tbi hundreds of wires lol

 

skip right past the 4.3 and go 5.7 350 little more work twice the pleasure

 

but they are heavvvy and the drivetrain will have trouble holdin up

 

thanks guys, but I'm wanting to stay toyota engine.

 

Go 22r..I had to look up what a 21 R-U was and it looks like its just the imported replacement to the 20r. So it should fit with no problems.

 

i have NEVER had a problem with any of that im running 350 turbo 400trans and 205 T case only clown one rear axle in 5 years detroit locker rear , i added 2 leafs up front to compensate

 

the 22re is a perfect replacement if staying toyota, double check the timing chain while the motor is out , not a bad idea to replace it if motor is used , much easier while out of the truck and costs about $130 total

 

What about replacing with a 6 cylinder? I see that posted alot but didnt know how much work and mod it would be. I found an old toyota van that the motor was still good but not sure about the mounts.

 

i have heard a lot of grief about the 6 cylinder motors, i would just stick to a 4 if i were you, i know the 6 mates to the tranny fine , not sure about motor mounts i would assume the same to make it easier in the factory to assembly, but im guessing at that,

 

I found a beater truck with a 22r carbed motor. The 21 ru is EFI. can this be swapped if i pull everything?
