i have no idea what's involved in changing a 1990 NISSAN 300ZX TWIN TURBO gear box is it just take it out and bolt the new one in or is it alot more (please help me)

Hi does anyone know the typical temps that a turbo down pipe would reach? The reason i ask is because im thinking of wrapping the down pipes again for my 2nd attempt! The wrap ive bought this time is rated to 540C (1000F) compaired to what i bought before that was rated to 1400F The price is more than double to buy and dont want to be wasting more money. Thanks Dan

Just got my new alarm delivered (TOAD Ai606) but now I don't know whether I should Install it myself or get a authorised dealer to do it? I am capable of installing it but will this invalidate the Thatcham approval with Insurance companies? What have you lot done with your TOADs?

Hi Looking at the japspeed site and they state that the decats for an na won't fit an auto is this right ?I'm surprised

Hi people...... I urgently need to get in touch with Mark, can someone pm me his number or I can pm my nymber to you to forward on to him. Need to contact him before 11AM. Cheers Alz.

Hi All just wondering if anyone can tell me what BOV's these are thanks

Thanks to Groover and those who responded to my questions regarding earthing out the ecu wire to the neutral switch on my manual gearbox. I decided to take onboard the advice given and went down the path of checking my engine timing and setting to 25 degrees btdc. It was actually set at 27-28 degrees meaning that it was too advanced. It seems a little less fumey now, however it still smells like it's running rich still. Obviously my idle speed has dropped as I have retarded the ignition a few degrees, but still purrs nicely. ANY IDEAS ON WHAT MY NEXT MOVES SHOULD BE WOULD GREATLY APPRECIATED ????????

The engine is nearly ready to go in the S14 but for the turbo to clear the steering rack the perfect solution is to fit a passenger side exhaust manifold on the drivers side, so 2 questions 1) Any performance/running issue in this? 2) How easy is it to drill/tap 6 new threads for the bolts as the are opposit to the orifinal ones? Before anyboddy gets confused this is a TT engine into the S14 body.

Hi there, just tried to search for answers...but it wouldn't let me. I'm getting the 120K service done soon, timing belt etc....But I'm getting a full service as well. I Have a 1995 N/A automatic 300zx so.... a) what the best oil to use for full oil change? and how much 2 litres? b) best coolent? again how much? c) Spark plugs? I don't think they've ever been changed? 62k on clock, worth changing? d) k& n oil and air filter? worth doing? e) rear brake pads, coz at the last mot they flag these up as needing changing at some point soon. any advice gratfully received, Adz

Ok here goes. I managed to get my plenum off today after a mind blowing task so i was just wondering do i get rid of all the pipes underneath as im going to do a water bypass or are there any vaccum hoses there.

I spotted a shiney looking red ZX in the car park of the flats on Gomm Road (opposite Halfords and B&Q) off the A40 on Easter Monday - around 2pm - was it anyone here? Good to know of another local-ish Zedder if so...... Richard:rockon:

Ok, My zed has been sat doing nothing for the last 2.5yrs. It is covered in all sorts of crap such as tree sap etc. Now i have gave it a quick wash to take the worst of it off tonight but there is still alot on there which isn't for coming off by hand. Now question is should i give it another wash then break out the clay bar? Or is there another way you would recommend?? Cheers in advance

Re fitted my reconditioned front brake callipers today, problem is I have just realised that the last time I bled the brake system, I inadvertently used DOT 4 as opposed to DOT 3 brake fluid. Should I top up with 3 or stick to 4? Worst still, do I need to re fill the system with DOT 3? If I do top up with 4 will there be any long term adverse affects?

Hi guys, after tinkering with the ZX the other day I noticed that when i remove the vacuum/boost line that goes off to the 2 dump valves ( piston type) and blow into it I can hear air escaping past the piston and out the trumpet on both DV's. Surely this is not good as it seems to me that this a serious boost leak. I have opened up the DV's and the brass pistons do look a little scored, anyone experienced this? I am leaning toward replacing the DV with diaphram pistonless Greddy type where there is no chance of air leaks unless the diaphram is u/s.

For a while now, particularly from start up, it's as if I have no PAS, really have to work the wheel to turn. I've read the various threads regarding this problem and have still to get the car up on my mate's ramp to see if it's the UJ that's sticking. But here's thing, last night went out in really heavy rain to get some petrol and the steering was absolutely fine this morning. Then I recalled that when the problem first arose, it was 'cured', for a while at least, after I jet washed the car. Is it possible that the rain/water acted as a lubricant? All comments welcome as ever. Regards Ronnie

What can cause this piston crack? If you cant see well there is a crack on the side of the piston between the first 2 rings, and a piece came off. Fortunately it didnt came off the piston and made no damage to the cylinder. It just had no compression and very much smoke came out of the breather. The engine is a vg30det, cima single turbo. I just had my new poncams fitted and i raised the pressure to 1.5 bar(21 psi). Single turbo precision pte5857 billet. I'm guessing it around 450 hp. So this the limit of the det pistons????

Only problem I think I may encounter is the battery is not as secure as it could be. Watch this space :sweatdrop:

hey, anyone know what paint code the silver zed is, its 300zx_666 's car. thanks guys

Hi, has anybody any idea where I can buy just the sandwich plate bolt/thread thing that screws into where the old oil filter goes? my old mechanic lost this and cannot use my cooler unless I find one. Cheers =)

Just a quick question, I'm doing a service on the 300 tomorrow and will be changing the plugs. Question is, To remove the coils do i just remove the 2 bolts that hold it to the manifold and pull it out or as it seems with every other job on these is it alot more complicated than this?? Cheers in advance

Have a look anybody used these? ebay Item http://www.ebay.co.uk/itm/180845321525?ru=http%3A%2F%2Fwww.ebay.co.uk%3A80%2Fsch%2Fi.html%3F_nkw%3D180845321525%26_sacat%3D0%26_odkw%3Doil%2Bfilter%2Bwrench%26_osacat%3D0%26_trksid%3Dp3286.c0.m270.l1313%26_fvi%3D1&_rdc=1

Im having issues with idle. All of a sudden today the car was trying to idle at 600rpm. Then would stall. Bit of history. The car had the water pump go about 4 month ago. The car never overheated. I only got round to replacing the water pump 2 weeks ago. and did the Cambelt tensioner idlers etc all at the same time. The other item changed was the PAS pump as this sounded aweful and was turning on the hicas light. The car when starting was a bit noisy from a sticking tapped but this cleared once warm as it had been sat but ran well. The car pulls very well (better than before the work) and is still now it's idling bad. Thoughts please where to start lookin…

Guys, I've just started taking the seats put of my '92 LWB to replace with leather. Before I rip the passenger seat to bits to utilise the electrics on the leather I'd like to kow if the old seats are actually worth selling? They're the blue velour type material driver and passenger electric. I don't want to take all the electrics off the seat if I could sell them to fund something else you see :)
