I bought my friends rebuilt 22re from his 85 4runner and I wan't to swap it with my 91 22re. My question is, what is compatable? The machine shop said the blocks were the same but what about the heads?

 

it will swap,any thing diff will interchange.

 

they are the same.

 

Ok, the only reason I am woried is because I know the 84' block is difernent so I wasn't sure if the 85' might have a difernet head so I couldn't bolt up my intake or something.

 

didn't the upper plenum change in '91 or '92? it became a better design because after that, it was straight while earlier ones were angled down.

otherwise, the long blocks should be exactly the same.

 

Thanks guys. That eases my mind about that swap.

 

I think it was 89. The newer ones eliminated the air valve and the air flow was also improved, giving quicker throttle response and better power.

 

Yea, I was planning on swaping the plenum anyway because all the pugs are diferent. Sounds like it should be as strait forward swap though.

 

How come your swapping the motor?

 

I think my current motor is on it's death bed but I am not sure. I got the re-built motor for $400 from a guy who just needed to get rid of it but now that my oil presure gauge quit all together, I really don't know what condition the motor is exactly. I man not swap for 50,000 miles.
