No PTU yet mate? :(

Hi guys, I have a 300zx H reg twin turbo. ad my mate do some work on it and he left the bunch of 6 earths (ithink 6 anyway) off the engine, then tried to start it, this caused the ignition amp to get red hot and fry itself as earth was tried to be foun,d so ive fit a new amp, and found that i have no trigers to them, or the ignition relay. I now suspect a blown ecu aswell. So where is tere ecu located? (people keep sayin different places). Please help, or if there are any more ideas of faults. It was a perfect runner till he did this.

Hi, I "may" soon be putting on some nice 19" wheels on my car and am looking to buy lowering springs from Mike at MJP. On his website he states you can specify the drop, spring rate, etc and as I'm looking to keep the ride height as close to stock as possible (whilst reducing the arch gaps) I thought these would be the right choice. For the time being they'll go over stock JDM struts (relatively new). Questions: (1) Has anyone else bought these springs from MJP? And if so how do you rate them? (2) I'm looking to install these myself - what specialist tools are recommended? Many thanks! Dan

I've installed my amp in the car.. but there is a constant winning sound from the speakers. The power cable runs down on the right side of the car and the rest of the cables (speaker/phono - rca) on the left side. I've never had this problem when i've installed my amp in other cars. It seems like it is the altenator??? The wining follows the rev.. Any ide. Bad grounding on the amp????? (but if so, then the amp should not even turn itself on)

how do you split the engine from the gearbox. it is an auto. i havent removed any bolts as of yet

hi mate tried to pm ya but your full!!!!!! :)

If I were to buy a leather seat trim kit would I leave the tweed on or are these removable ? Remove tweed covers and refit with leather ? CheerZ Paul

I took my wheels off recently and put new (third hand!) ones on. When I took the front wheels off, one tyre had worn much more on its inside edge. What should I get done to stop the currect tyre wearing like that? Tracking? Something else? Cheers!

I saw a grey 300 going south on the M1 at watford gap area at about 9pm(ISH) last night And another grey 300 with lovely big rims going south on the M6 around Jnc 16 at about 5.30 am this morning ( I was in the white astra van that flashed you as I went past)

I replaced my jap spec rear lap belts with UK 3-point ones today and had no problems. I was planning to replace my door mounted belts with UK pillar mounted ones at some stage too. However, although the mounting point were there with the threaded back plate for the rear belts, there are only holes for the front belts - no threaded plate to screw into! :mad: So, can I just not do it? Or is there some way round the problem? Obviously I don't want to do anything that's going to make the seat belts useless if I do have a crash! :headvswal

Ok, so the tailgate on my car has been smoothed....and done badly. I'm very picky when it comes to bodywork, and if it's not perfect, I'll get it sorted. There are areas where you can see filler in the holes, the tailgate itself also has some small dents on it. Now, I've gotten bored of the tailgate looking so bare. I do like it, but keep seeing Zeds on the US forum with their OE 90-93 (series 1) spoilers still on...and I'm starting to like them again. 99-spec just wouldn't suit mine with it being pearl white and I've yet to make my mind up about the lip spoiler. I know most here hate the original spoiler. But I'm wanting to keep mine original looking …

Does this particular symptom ring any bells? Driving about 70mph, box is in 4th (overdrive) at about 3000rpm, then for no reason it changes to 3rd and revs obviously shoot up, then after about 2 secs it changes to 4th again. It keeps doing this about every 10 secs. Fluid level appears to be ok and looks new. Ta.

Was running at usc today, pulled a 13.6 if i remember correctly.

just to let the people know in the north west area me being a roofer did a small job on a refridgeration expert today and i spotted a bottle in his garage of r12 :bow: :bow: he said one of the last that he knows of, anyway say no more iff you need some and can get to the wirral let me know

Hi. I'm looking at buying a Z and have been doing some hunting and searching and wondered if any one on here could offer some advice. I'm looking for a manual twin turbo, and so far the only one I've found any where near me is from a company/trader called Import-ance (http://www.import-ance.co.uk). I'm in south east London and it's in Slough, but seriously that's the closest one I've found! Does any one on here have any experience of this company? The guy has a 94 silver Z on auto trader which I'm quite interested in, 51K on the clock. I've never owned a Nissan before (all Honda's) so if any one knows of this place or has used them before advice would be great. …

Hi all :) ive just bought a 300zx fairlady twin tubby and theres a switch next to the auto gear stick that says power and hold.please can anyone explane what this button does? also the clocks are in KMH not MPH where can i get them chainged? kind regards cainy :duffer:

Fitted my hids a while back but only recently noticed ive lost my drivers side main beam (hids are on the dipped circuit). Im a bit confused why.... my hids are wired with a new relay wired direct from the battery to the hids. The relay is triggered from the passenger side stock dipped circuit, and then connected to each of the ballasts. The HID's work fine but i have lost the main beam drivers side. THe sotck nissan dipped circuit drivers side is disconnected (as i only need one trigger for the hids..) but surly the main beam isnt dependant on a working dipped circuit.. Ideas anyone? (Also, how damn cool are HID's :dance: :dance: :dance: )

Have been trying to delimit the Z but to no avail. Have put a new chip in the ecu but dosent work. Will only run on 3 cylinders then. Bought a new ecu but still no luck. Don't wnt to put the new chip in the ecu yet as it may well bugger both. Noticed that the old ECU I have is different. It had a mitsubishi chip in it (which was destroyed by the guy putting the new chip in). Anyone know where I can get a new upgraded chip that will fit my old ECU and delimit the car and turn it into MPH. The old ECU unit is an impul motor racing development one. It says hi-power control unit on the top with a serial number of Z32M-N003. Any advice would be appreciated …
