Conclusions from my last question seem to point to either the gearbox mount or the prop shaft bearings...I do have some more information now and a further question: I took the car on a longer journey over the weekend (I only do about 10 miles a day normally!!!) and when properly warmed up the vibrations were no where near as bad as when cold/cool. They still continue when I take the car out of gear. Does this point more towards the rubber gearbox mount (someone suggested that when old and worn vibrations get less as the rubber gets warmer)? are there any particular visible signs that can be seen to determine the gear box mount?

My autobox is giving trouble all the time and was wondering if i can fit a 6speed gearbox from the R34?

when running at 1.00 bar it still feels the same as the stock boost? Is it just me expection a big differance, or is it just a very suttle differance? :confused: ;) :confused: :confused: :confused:

Will the blitz 03's go over the brembo large brake conversions?? I dont want to buy some and they wont fit:rolleyes: If i do get some Davew please forgive me :D It was yours that have inspired me and i promise to only use the best bottled water to clean them :D Kirbz

Sorry to ask, but is 1.00 bar of boost ok for a stock engine with a hks intake and SE chip? And i'm not gonna brake anything with it that high am i?

Hi all, Still trying to identify a problem I have with power drop in the upper rpm range. Looking at the CAS at the moment, checked the voltage of the base setting (reference, pin 41/51) measured at the ECU and it fluctuates by half a volt or more for no good reason. Checked the voltage of the position signal (42/52) and it's spot on and steady as a rock, changes slightly for increase in rpm... Can anyone please tell me if the voltage of the reference or 'base' setting should be stable for stable idle rpm?? I would have thought so. If so, can this be due to a dodgy CAS or would that be too easy?? No error codes but timing mysteriously jumped to 15 degrees a…

How good are they??? What is the difference between the manual and auto...? Let's not have a slanging match but constrictive critism... Cheers Ben

Its deffo a love hate thing. Messing with my boost controller today to increase the boost and no joy, i can get her to 17/18 psi and peaking at 19 when it was colder but not above that...i know its a lot anyway but if you want more power you gotta have more boost!!! Even at the boost controllers full settings it stays at 17/19 psi?? BUT here we go...just did a ecu check and guess what code came up?? You guested it code 34...b*****d Is this why i cant boost any higher? Would i be able to boost that high while the ecu puts me in safety boost? I am in the process of resetting my ecu to see if that will sort it. Cheers Kirbz (l…

Hi you ever so helpfull lot, Today the car has been a pain in the rear end, it's an auto but when I switch it from Park to Drive or Reverse the revs drop and feels like it's gonna conk out, also for the first time today it stalled when stopping but when went to restart it just keeps turning over but not starting, then when it did actually start up the Power light on the dash kept flashing for a short while, another thing was whenever I go to put foot down when pulling away the revs dropped again.........really annoying me now. Yesterday the car was revving at 3,000 revs at 50 mph, usually this should be about 2,000, could this all to do with one problem does any…

Anyone know what i should set it to? I have a SE chip i think, and cant make much sense of the manual!

Just fitting jwt ecu & 1mm mig welding tips, can any one tell me if i need a new boost gauge, if so where & how much are they. Or is it ok just to run it as it is?? If i need one where do you fit it? is it a pod or goes in the proper bit of dash??

hi, My friend has just fitted my Blitz SBC ID and power meter.:D but it is not working properly :cry: Please help :confused: The following are what we need if posible: 1. The power meter displays "calibration error" when you try to calibrate it, my friend is not sure he has connected it to the right cable from the ecu. does anyone know which cable/colour we shuld connect it to at the ecu?? 2.He has took the pipes off the stock boost solenoids but nothing else. does he need to disconnect the wiring from these and if so where do you do this? 3.Do the pipes from each turbo need to be the same length. will it make a difference if one side is longe…

Just wondered if anyone can tell me if the boost guage tells the boost from both turbos combined? For example, if the guage says 8psi, does that mean that both turbos are kicking out 8psi or does it mean that each turbo is pushin 4psi each?

My fairlady is loose around the bottom. I mean, The logo transfer on the back is peeling a little around the bottom. How would anyone suggest I re-apply it without messing up the plastic finish? I seem to remember another post somewhere about someone getting a new one- is this rubbish? I like it. I bet it's something else loads of people would be quite happy to get rid of. I like it!

I am removing the engine for a rebuild but cant decide how to pick it up as not having any hook points,not sure the best route! Anybody out there found a good method?

what do i need to do to read ecu codes on the ecu i understand there are various flashing lites on the unit if there is a fault but once i uncover the ecu what do i expect to see!! cheers Dave:confused:

I need a new drivers side rear light cluster. I have a 91 Japanese NA- will UK light clusters match if I was to get a 'second hand' one from a UK car, or are there differences? It should be easy to fit, shouldn't it? Just disconnect old one and reconnect the new, taking off the plastic lining panel in the boot? Anyone have one lying around that is in decent condition? Rich

My car has starting hesitating or missing/struggling to go when maybe in 2nd gear and not flooring it but accelerating away ! any clues on this not machanically minded so laymens terms please:D cherrs Dave:dance:

Just thought I'd make sure before pulling things apart. Cheers Jon

Hi there people, im just about to buy my first ever 300 zx and just want to ask a simple question, how much power does the N/A 3.0 have same question for the twin turbo both in standard form cheers neil:dance:

This is getting to be a habit :D When i bought the car it already had traction control fitted...great It is a racelogic one, even better, i have all the installation instructions and setup disc etc but i dont know what the settings on the traction are? I have spoken to racelogic and they say it cant be one of theirs because theirs only has 6 settings and had always looked like this now mine looks like this and it has 10 settings :confused: :confused: I know it works cos i had it on in the rain the other day and floored it and it sh*t me up when it cut out. So does anyone know what it is or is it just an older racelogic model?? …

Hello again What gap do i leave when putting these plugs in, i think the standard is 1mm but if i'm running more power should i have it less?? Cheers guys Kirbz

its been making weird noises ever since I've had my zed:confused: even if I go up slight hill I can't hold it on the clutch cos it makes a horrid loud grinding noise, big hills are a big no no as I have to use my handbrake...... see other thread about that:cry: is it the thrust bearing? (sounds rude to me) or do I need a new clutch or can it be fixed? its starting to piss me off now

I have a workshop manual that covers my old Seies 1. Now have a Series 2 as well so should I both getting the overpriced supplement? What's in it

Hi all! I am changing front brake pads tomorrow. I think I read if doing this it is best to change the shims as well! Are they easy to get? Like tomorrow! And where from. And whilst here, is the air con belt the same as the fan belt?doh! Or do they just put that on it to lable it? Is this easy to do to. I would imagine its in the web manual can someone tell me the page please.
