R32 Gtr Dump Pipe And O2 Sensor Mod

[portaz]

Hi guys I have searched under o2 sensor mod and r32 gtr dump pipe and cant find the answer, I am installing some hks dumps I got from here onto my new turbos and have found the 32 o2 sensor is too small, so I understand just jap sell a suitable plug (who i will call tomorrow) but looking at it the sensor protrusion would not be far enough? How does everyone go about doing this? I was thinking I could grind and file half the bungs on the hks dumps to allow further reach or get r33 o2 sensors or just get the correct dumps?

What ECU are you running?

If Power FC, get your tuner to disable the O2 sensor - and whack a bolt on the dump pipe (This is what I'd do) or get what you're going to grab from Just Jap.

R33 O2 sensors have different wiring to R32 from memory but someone may be able to confirm or deny it.

I am using nistune I guess I could drill and tap the new dumps to accept the bung from the stock dumps?

Or you can buy R33 O2 sensor and run it unplugged until retune so your tuner could swap the wires around?

Just a thought.

Here's where the xforce splits put the o2 sensor when you use the r32 screw in adapter (the welded in bung is for R33, the adapter screws into the r33 bung). FAIL.

So i had that bung cut out and the screw in adapter welded in, so the sensor is in the gas stream;

Then i ground it flat;

Awsome pics I was hoping not go the welded route but I guess there little choice thanks for the replies guys

Don't run R33 O2 sensors, they are zirconia based. R32 ECUs expect titania based sensors (both are electrically different)

[Count Grantleyish]

Ah, I knew there is difference between these 2 O2 sensors.

Scott, in your case, adaptor + some work is only option.

Good to know will stick to the mod route of r32 ones then

Get a power fc and run anyone u wish....or even none at all
