Oxy sensor on red top

[petrolhead]

hi guys. i have just fitted a set of 20v headers to my red top and found oxy sensor hole is a totally different setup (20v has a screw in type further down the header, read top has a bolt on flange). Does anyone know whether you can wire the screw type in, as well as extending the loom to reach the hole further back? cheers

[levinguy]

off topic but, that seems a bit weird, i've had 3 silvertops, all with the flange type oxy sensors, is this a facelift/prefacelift thing?

As far as I am aware 20v are flange type (and 4 wire). Plugs differ between blacktops and silvertop.

Ahh forgot to mention they could be aftermarket headers. hmm.. might get a flange welded to exhaust. Spare sump plug filling hole at the mo.

yea sounds like youl have to find a screw type oxy single wire with no heater for redtop

One of my co-workers uses a bosch universal 4 wire oxy sensor in his silvertop. If thats any help at all. But i take it the loom still has a 1 wire plug?

Try pick a part for oxy sensors off camry's or celicas i think most have 1 wire screw type that will fit.

one more tip do not cut the oxy wire before the plug if you need to change it. It's not a typical wire inside and cutting can change the behaviour of the oxy reading

silvertop drives a heated 4 wire

Yeah i know but from what i gather is that the head is a silver top while the remainder is the original redtop loom included i'm asuming, or did i miss something?

no he has a silvertop exhaust manifold on a 16v red top head

no he has a silvertop exhaust manifold on a 16v red top head

That is correct. Looks like i will try find a camry one.
