Are the o2 sensors and precats the same on auto and manual turbo 300zx?

car was already warm... drove up the road and back (about 5 or 10 minutes).. when I pulled up I noticed this on the floor.... but it was cold and wasn't there before I left... any thoughts?

The Zeds been parked in the garage and only driven to the shops everynow and then. I drove it this morning and noticed the stock oil pressure gauge was sat on 0 for the full 10min drive. I've got aftermarket Option gauges which was sat on the max 100psi reading throughout! I checked oil levels which look good and no leaks etc anywhere that I can see. The car drove fine as well. Should I be worries? Likely just an issue with the sender unit? I didn't fit the aftermarket gauge so not familiar with how/where to check it but was planning to drive the car tomorrow for a bit longer so wanted to check with the knowledgeable folk on here whether I should be worried abou…

Nice looking standard car, not seen in this area before.

I was curious is it possible to get decat performance without the loud amounts of noise? I have cat exhaust but the rear piece is custom and i find it rather loud already!! Can you maybe get exhausts that are quieter at lower revs and sound louder when reved harder? I was reading up and heard it can be achieved with certain resonator or something... If anyone with better expertise could shed some light on this matter, it would be great. Do japspeed do exhausts with cats in them for the 300zx?

whats the best ones to buy guys please

hi, im in the process of buying a import tt auto it needs some work doing. im wanting to change the cambelt and was wondering were the best place to get one from thanks Rich

I have finally got round to replacing my throttle position sensor, the car now runs really smooth, except for every once in a while. All of a sudden the throttle will go from being extremely sensitive to an almost switch, power is either on or off. After a little while it soon sorts itself back out (or if I set cruise control). Have I replaced it with yet another faulty tps, I should try and clean connectors, what is the best way to do this? Thanks, Dan

Ok, so after a total of 8 or so hours we have managed to change the nearside turbo on my Z. For the passed 2 years or so it had been smoking on tickover (worse when warm). Touch wood, so far, it seems to be a lot better. I have left it running for well over ten minutes whilst the engine is hot several times and nothing yet. However, last night when the car was cold about 2 miles from home I pulled up to a set of lights and there it was, some smoke from the exhaust. When it was safe to pull over i did and let it tickover once again to confirm if it was the same side, but nothing. It wouldnt smoke for the rest of the night... It definatly seems better but am…

This Sunday I am going to change my manual transmission fluid and diff oil. Which oils do you recommend? Also, certain manufacturers have specific things to do after changing diff oil ( TSB for e46 M3 is to drive the car in circles 15-20 times) Is there anything similar for Nissan 300ZX?

Are there any wheel nuts available that are slimmer than the standard Z ones?

Who was it lol

ok got a sound like someone blowing a blade of grass between there fingers when i hit high boost with in the cabin, not sure what on earth it is and has only started happening since i change the clutch / flywheel / exhaust. Id of said it sounded similar to OEM dump valve goose honk, but i do not have OEM recircs on the car? i have z1 dump valves.

once i got my car running i have a Modified plenum with all the PVC/water/Balance Ports removed i was going to relocate the Balancing part of the plenum to the under/back side so it can not bee seen but in doing this the Pipe will not be 23mm in size like the original balancing pipe now i seen ppl have done a balancing bridge in front of the throttle body's .. i think this looks crap as the Ports for the recirc/Bovs are on the same pipe work but quit a bit before... would it be poss or be ok to put a Link there and work the Bovs back in ? i will still be keeping some form of Balance pipe on the back of plenum still but would be more like 10>15mm…

My son saw a black tt in Dereham, Thursday afternoon going through the town. I have been told numerous times by different people about this car, but never seen it myself. It has become a bit of a mythical beast. :)

Finally got my wheels for the car, Rays split rims with 225 fronts and 265 rears :biggrin: already split ready to polish the rims and then powder coat the centre the same colour as the car which is ....... Bargain price off SXOC. Who likes?

After changing both 02 sensors and checked a few other things, I thought I would run Data Scan just to check. As far as the sensors go, all appears to be good. Would someone take a look and see if everything else seems correct? [video=youtube_share;kbN_e6FoIKY] Sorry about the quality, Will try again at the weekend.

Anyone have a engine crane they are not using at the moment which I could borrow for a day or two? In the Telford area. Thanks, Hollings

Hi NOZ. you worked your magic , now gain some kudos . post the results pal and a copy of the dyno sheet. thanks Sayers

Just left my work and managed to do a 180 in the car park in the dry. As I reversed out of my parking space and round a bend somehow the clutch came off then rebit, in the second or so panic I took my foot off the accelerator then back on again just as it rebit in second gear. Now as I was turning the corner when the clutch re engadged and I had my foot on the accelerator the zed instantly spun 180 where she stood without the front wheels barely moving. My heart jumped out my body via my arse, I quickly jumped out checked everything out and luckily all is well and no damage, but if it slipped or should say unslipped what could have caused that?

Is there a how to on changing diff oil, going to attempt to do it at the weekend, thanks Dan

Hi guys, since owning my car I have never changed the manual transmission oil, is there a how to anywhere? Thans

Hi everyone Having a few issues with my Zeds brakes, nothing too major but would like some thoughts. First issue is a screeching noise when braking at low speeds. It is really quite loud. It seems to happen around 10 MPH but not above. Also, it doesn't happen if I brake hard and come to a stop, only when I'm inching forward in traffic or coming to a gentle stop. I've had a look at the rotors through the wheels and they seem okay, no gouges or marks I can see. One thing I have noticed while crawling along with brake pressure applied is that the screeching sound fades in and out. This makes me think that maybe the brake rotors are warped? This lea…

prob asked before butwhich oil do u lads reommend for my 1994 tt auto 110 thou on the clock

Hello all Driving down to get my brake pads and disks done today when I noticed steam coming from under the bonnet. When I opened the hood there was steam and water coming from under a foam seal from the top left side of the radiator. Im not too bad when it comes to basics but not sure if it's the radiator that is knackered or cracked or something.
