Trying to sort my gearbox out and was looking on ebay and found this, Is it true what he is saying you cant just swap the ecu over with another one? http://cgi.ebay.co.uk/Nissan-300ZX-Auto-ECU-31036-40P00-/190390274654?cmd=ViewItem&pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2c54250a5e Thanks

Is there a guide on here covering this subject? Something that describes the costs, process, timescales, what to watch out for etc?

My Z has got a misfire at around 2000-3000rpm, it runs really rough and sometimes I have to put my foot right down to get it to pull through. after about 3000-3500rpm it springs back into life and runs really smooth again... I have noticed it is using more fuel than usual, there is a hell of a lot of black up the back of the car & when the revs are held to make it misfire the nearside exhaust seems to shake and splutter as though thats the side its coming from. Also, it only normaly does it when it is warm. Cheers guys, Dan

Hi mate, just sent you a pm about my car. I thought i'd post this as by the looks of things you will be getting loads about Steves car and parts. Cheers

How do they come out??? I have forgotton. Its ages since I did one. Is there a catch hidden or do you just need to pull hard?? Help!!!

Can one of you experts tell what to set my EBC too too achieve 1bar on Hi, if you can help can you fill in the blanks below? :chef: Set = Gain = Start Boost = Warning = Limiter=

I've recently noticed an intermittent problem. Sometimes, following full boost, the car seems to be hesitant, a little juddery, almost as if it's running on 5 cylinder. This sometimes disappears with further driving or on restart. Would a boost leak or a faulty knock sensor cause these symptoms? An ECU test showed no faults. I've checked all accessible connectors and they seem fine as is the series 2 PTU. The engine harness was replaced a few years ago. If this was a constant problem, I guess I would look at the plugs, coilpacks, injectors etc. But this is an intermittent problem but annoying just the same. Any ideas? Cheerz

hi all, well another summer, another problem arises!! over the last few weeks car has started to develop a weird squeel, it does it on idle more than anything else and sounds consistent at 1 pitch (imagine the sound a jet engine produces), i get the feeling its a belt of some kind either loose or rubbing on something, also this may not be connected but it also feel as tho the car is running very rough on tick over at lights ect, almost as though its chugging like a tractor although not as severe obviously, the squeel dies as you kill the engine, but not instant, it dies over about half a second as the pitch dropps off. on the way home tonight things got much wor…

Is the z running yet ? progress info........

im getting a bit of white smoke form the drivers side exhaust it only seems to happen when the car is idling its very a now and then thing but when it does do it the idle goes lumpy i noticed that today, its left a soot deposit on the exhaust, i 1st thought oil seal on turbo but after talking to old owner he suggested changing pcv valves 1st theres no smoke when the turbo's are boosting so now just looking for any more opinions . thanks in advance for any help

Like many on this forum, you probably have always wanted to get rid of those faded velour seats and trim! There is always the option of re-upholstering the car, but does anyone know if it is possible to dye the fabric to a different colour? I have heard of people 'painting' the fabric and seen a number of products that allow you to do this, but to be honest, I would hate to think what the results might me. However, if such a product exists, it might be possible to use a brush or something similar to apply a strong, permanent dye to the fabric. Anyone know more about this?

Perfect backdrop helped make this a perfect pic

Big chap with mohawk in a burgandy 300zx, gold alloys, one of those strange bolt on spoilers. I know you clocked me, was parked 2 cars behind you, but didnt seem up for a convo.lol. Been seeing a few lately!

Hi everyone....:thumbup1: My Z has been parked up for a while now and i`m in the process of getting her ready for m.o.t.. I have noticed that the left control pod, Air con. Wipers etc will come on then go off.. but recently it will not come on at all.... Took front off and tested for power off electrical plugs, no power?:angry: Has anyone heard of this problem b4? Any help greatly appreciated!!!:clap::yes:

I was told that 740's were on my car when I got it. Found out today I have 450's. explains why the 500+ ( on an honest Rolling Road !) was proving very illusive. 650's on the cards now.. could be a very good year :)

Since we usually hear from the complaints dept, I thought I'd give a bit Thanks and high recommendation to Ryan at 2Bartuning.com He came by my place today for a CSI Miami operation on my MOTEC system. Took a lot longer than we expected, but in end figured out that Owens Developments didn't changed a gear change setting when they took it off Full-Throttle gear change. Overfueling like crazy at gear change and caused me to miss JapFest!! :( It's driving like a dream now. :) Thank you Ryan!! ( and also to SilverBullet for a similiarly Top-Class mobile mechanic experience 2 weeks ago! ) If you ever have any ECU questions, or an after market set-up…

Thought my car battery was dead, brought it up to the yard to charge it, but the charger is saying fully charged, put a volt meter on it, and its showing charged also, apart from my immobiliser, what else would cause no power to anything, no lights on dash, no nothing, not even the map reading lights that the immobi doesnt stop working? checked to make sure the battery connectors are properly on. typical the day i try and move the car after dragging my self down to it, i have no power.

help. last week i needed a maf sensor to check my new ebay sensor, found 1 ebay sensor u/s. now need to buy a good 1 but not at nissan prices (£313+vat) any ideas. 1990 n/a 300zx cheers mick.

A very small one? Found 6 boost leaks some on pipes i removed but some on pipes i have not touched. I pressurize the system to 5 bar and there is a very slight hiss from rear of engine! i have moved pipes, removed/refitted pipes and loosened and tightened clips but cannot seem to sort, is this crucial. As i said very small hiss on 5 bar. Dave

Ok so my car is now in the bodyshop to get the front bumper sorted, so I thought i'd start this thread to show progress. This is what it looked like when I first had it: Lots of damage and paint missing. Currently bumper is off being repaired as follows: I bought some ABS plastic mesh off ebay to tidy up the big gaping hole and im gonna get the number plate repositioned! More photos to follow on the road to completion!

Howdy all, I am looking at buyin a 300zx. Is there anyting i should look out for, Aslo is there any common engine problems? :tank:

Hi everyone, long story short, went to zedworld today for a check up. found some good things and some bad. i have a boost leak which involves taking of the engine loom and looking into the gaskets (£300) job from zedworld. but i found out my ECU is chipped to 400bhp and my exhaust system is worth a lot of moneyso could be worse (and i got a free sandwich!), i just cant access that power with this damn boost leak! so basically if anyone is near manchester with some mechanical knowledge that reckons they could have a go at it, id pay you! any takers? as you can tell, i do not know much but i am learning! cheers

newish z owner seen a few of you guys about dunno if any are on here. if you are get in touch would be cool to know who is about or if there is a local meet
