Oxygen Sensor Dump Pipe Adaptor?

[kx2fity]

Have just purchased some 34 N1s for my 32 GTR.

The turbos came with split dumps (possibly jjr or hpi or similar) dumps are heat wrapped so am unsure of make.

Anyways I tried to use of my original dump pipes the adaptor for the oem O2 sensors - however the original adaptors are slightly to big (1-2mm) to fit into new dumps?

Where would I get an adaptor?

Can you get these readily ie from somewhere local?

How have people dealt with this before?

Also one of the dumps has a second hole for possibley exhaust temp sensor??? Could I just find a fitting bolt an close it up?

Thanks in advance,

Dan

R34's used a different size O2 Sensor, hence the problem you are having.

You'll need a reducing thread nut thing (nfi of the technical name), and use that.

Or buy the proper O2's to fit the dumps
