ford'ssubaru's Posted September 24, 2015 Share Posted September 24, 2015 To the best of your ability try to keep it as OEM on the Brat. Only because I have a soft spot for the Brat and there are very few of them left as OEM....... Hoping to get one. Switching manifolds is fairly easy.

iluvdrt Posted September 25, 2015 Share Posted September 25, 2015 I have a 100% OEM barn find BRAT in my avatar. I had to change it out to a weber and magnaflow (among other things). The issue with the Ca emissions is that none of it can be purchased new. It creates vacuum leaks and robs performance (what little there is). Also, my 4 speed began having issues, and once again, no one has a 4 spd rebuild kit. (found out later the trans wasn't the issue) It literally started to become undrivable and I am not wanting to waste money buying parts from "Bob's" parts stash in Michigan or South Dakota that may or may not work. BRAT's and many EA81's are modified to simply just keep them on the road. They have to evolve so to speak lol. 1 Quote Link to comment Share on other sites More sharing options...
