hey guys im just changing the stock cat on my GTR to a new x-force piece.

just wondering is there any difference between a cat for BNR32 and HCR32.?

the new cat i have looks exactly the same and fits on perfect, however the exhaust temp sensor hole on the new cat is up the other end (of the cat) to what the one on the stock location is, and my sensor wire//cord does not reach the hole to screw in..

now the cat does have a flow direction indicator on it which i have installed so as the arrow (for direction of air flow) points to the rear of the car.

have i goosed something up and put it on the wrong way or is this cat i have actually for a HCR32 model.?

cheers.!

I always thought 32Gtr and 32Gtst cats were the same because it is very common for people with a gtst to install the gtr cat. A possibility is to not run the sensor at all. The sensor does not effect how your engine runs in any way. However it does let you know if your exhuast starts to overheat which i have never heard of happening.

I do know 100% that your correct in saying the arrow on your cat is pointing in the same direction as the exhaust flow.

Um, isnt that the O2 sensor? If it is, you do kinda need that!! And the GTS-T and GT-R cats are completely different, the GT-R cat is the best you can get, better than most aftermarket cats, which is why they are so expensive. If you find one, buy it!! Can you extend the wires by cutting them and soldering a new section to them? Make sure the solder is of decent quality and covered. Otherwise, gut the cat and weld a pipe through the centre. I would never do it, but you might get an extra 3kw!

Ok its definitly not an 02 sensor. If it was an O2 sensor why would they put if after the cat??????? (cat removes unburnt fuel & cat sensors unburnt fuel)

I am 99% sure its a heat sensor.

Ohh and when i ment they were the same. They are interchangable, the gtr cat is obviously better.

Pretty sure you can't solder the wires either because the sensor/wires get that hot it would melt the solder off again.

I'd say ditch the sensor.

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      By Rezz · Posted

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
