Another Header Question 20R
 

I have a 79 toyota pickup and want to get a header for it. Will a header made for a 1981 22R fit and work correctly? They have the same round exhaust ports i think. Thorley doesn't seem to have listed a header for a 20R and thats the header I'm wanting to get.
:yotarock:
thanks in advance

yes ! when you get it cut off the garbage collector and weld a ball joint collector on.

thanks for the info.
I cant wait till february when i get back from vacation and start working on the '79. weber carb, gears, lockers and lift all sitting waiting to be installed.
oh well, i guess i can spend another few months travelling first...

To the best of my knowledge, 20R/22R exhaust headers/exhaust gaskets are interchangeable. Intake side however, is not.

Lce headers are better but they cost a little more

I picked up a Headman header from a local hole-in the wall parts place for the 20R in my '78 celica. It wasn't overly pricey(about $220 Cdn), and it works real nice.

It was advertised as fitting 20R/22R.

Headman Header
 

I installed a Headman Header on my 83 Mojave (22R) It really helped with the top end power, very happy with it. FYI: also P&P the head and put a new cam in to match up with the header. Don't forget to upgrade your exhaust system too. I went to 2 1/4" freeflow. Good luck with it. :)
