Doin my first toyota engine swap in my 84 from a 22r to a 20r. i have the motor in and bolted up everythings fine there but im having a little trouble figuring out the vaccuum lines and hoses. i have most of the vac lines figured out but theres one bigger hose under my intake that i dont know where it goes, when i put water in my radiator it comes out of this hose. if anyone could tell me where this goes it would be much appreciated.

 

If its the one im thinking of, it goes to the heater.

 

it might go to the choke.

 

its a larger hose i can stick a spark plug in it with room

 

yes it was to the heater thanks

 

Hey im a lil curuious as to why your changing a 22r to a 20r?

 

Put the 20r head on the 22r block...

 

thats what i ended up doin love the power!

 

hey, in case anybody wants to know... I'm pretty sure the 20R is the same as a 22R EXCEPT for the bore...

The 20R is a de-bored 22R...

But you wanna try not using a 20R b/c of the smaller and harder to replace carb...

For the 20/22R Hybrid you get a carb adapter from LC Engineering so you can use the 22R carb...

That is all

Good on'ya Missouri...
