Hi guys, How does a detonator sensor work? I cant find any detailed information about it. All I can find in the 300zx manual (cd) is a small paragraph on knock sensors. Is a knock sensor and dett sensor the same thing? What is the dett sensor actually sensing? Is it heat or knocking? Also, how much is it to buy a new sensor?

Hi guys Im looking to buy a mannual turbo 300zx but ive only got £3000 to spend, can i get a good one for 3k or am i gonna end up with a Z with loads of problems? Thanks Yammer5

Drilled a hole throw the fire wall to put boost controler cables threw near the throttle cable and smashed the lid off a little black box on the inner wing with the drill it has a plug on the bottom and a small vacum pipe connected .It runs but misfires badly does anyone know what it is and how much are they thanks taff.

Right, I have noticed lately that when I'm out and about the cars idle speed sometimes sits at around 1500 rpm when I take my foot off the gas, and other times sits just below 1000rpm which is about right, its a swb tt. I'm thinking its maybe related to an idle speed sensor or something, but I'm probably way off. If it is that can it be cleaned or does it need to be changed, and where can I find it in the engine bay? Any suggestions?

Hey everyone. I've been doing alot of reading about 300ZX's and alot of people say that they have overheating problems. Naturally I've read the FAQ's and so on. One mechanic I talked to said they dont overheat too much but are a pain in the ass to work on because of lack of room etc. I was just wondering what you have experienced in your cars? Are they hard to work on? Have you overheated? The cars are reasonably cheap here (australia) and thats because of the image of them being overheating/hard to work on pains. . .any advice or help you can offer would be most helpfull.

Getting a pair of these for the fronts £50 Ant views on em , anyone used em?

I recently swap a na for a tt. I was having issue starting the engine (Injectors were clogged) I've fix that I started it this afternoon, engine seems to work fine. but this is my first turbo car and i just want to know if boost is normal... on idle i have 20 psi of vacuum, I can't put the car in gear already so I rev the engine on neutral like 4000 rpm and only get 0 psi on stock turbo is this normal? will i get more boost when a gear is engage?

One of my coil packs has a zip tie holding the connector onto the top of it. I removed the zip tie to see what would happen and it stopped firing on that cylinder. On closer inspection the clip that holds the power wires onto the top of that coil pack has broken off. The clip appears to be part of the connector on the end of the wire not the coil pack. What i want to know is can this wire easily be changed by removing the throttle body cover and unpluggiing it? If so anyone got a spare one? Put another zip tie on for now and cylinder is firing again!

I staggered past at about 11:30 carrying my girlfriend. We noticed some tw*t had put their left-over drinks bottle on the roof- how thoughtful of them! Mark

Noticed earlier that I had smoke coming from my left zorst. I've had the ConZult hooked up to it and I have a code 33 'O2 Sensor (left side) The O2 Sensor is open or shorted (abnormally high or low voltage is registered)' The readout on ConZult is totally steady for the left and moving up and down for the right side, would a faulty sensor cause excessive smoke coming from the zorts? Also how would I check the sensor, is it a case of putting a multimeter on ohms and see what the reading is from the connector? All help appreciated. :bow:

can anyone recommend anyone do an aircon regas on a car (not a Zed) without attempting to rip me off? any help appreciated ta

It always starts the second or third time with help of pressing the gas pedal, what should I check first, any ideas? The best way I can describe it, it feels like the air filter is blocked, or it's coughing up first two times untli it starts, almost like a lazy fuel pump....

Hey Some of you might know, but my car is running on 5 still. I was under the impression that it may be the coil pack, so after checking all the plugs and finding only one that was obviously not arcing I changed the coil and crossed everything. It didn't work. The coil was not at fault. Running out of ideas now, but I am just about to do the most simple and change the sparkplug incase its that, but I have some questions. So my questions are: Could it really be something that simple? Is there any way to check for a spark? i.e. Remove the coil and plug and spark it against something. Is there any way to check the plug connection to the top …

Ok, my next step is to up the boost, car is uk manual has veilside evolution exhaust and stillen induction kit. Running stock turbos at the mo so would need to be a bit carefull? I have been advised to use an electric boost controller, @£445. As manual controller not so accurate? i pressume this includes the chip and remap although this isnt specified on quote. Also told a fuel cut defencer would be needed too @£95 This all comes with a labour bill of £400-£450 + vat So a bill of over £1000 is expected. Would this be about right? Your advise plz on best wat to up the boost. many thanks carl
