I'm working on retrofitting SPFI to my EA81 Brumby (Brat), and one of the pre-requisites is hooking up the o2 sensor for feedback. Problem is, we didn't get any EA81 or EA82 vehicles down under with SPFI, only MPFI on late (1990+) 2wd sedans.

Does anyone have a photo of where the factory position for the o2 sensor goes on a EA81 with the US-fitted feedback carb setup ?

I don't believe I can fit a MPFI L-series exhaust setup to an Brat, but if anybody's done it I'd be glad to hear from them!

TIA.

Dean.

I have an EA82 y-pipe on my Brat - had to grind some on the cat's heat shield to make it fit but otherwise it's fine.

Alternatively you could just put an O2 bung at the crotch of the y-pipe - that's where they are on SPFI's.

I am guessing by now you may have worked out a Y pipe off an mpfi L Series will have an O2 sensor and fits in a Brumby. I've done it recently now just needa reader to go with it.

 

Dean, did you give up or is Tweetys set up excess to your requirements ?
