hey guys,
ive just got rid of my cruddy bmw 316 compact.
just bought my first 300zx twin turbo! had to travel to london to get her, needs a bit of work tho, got her back on sunday nite,
bin driving abit since then and ive stumbled across some issues/problems i was hoping you could help me with.
ok, ill start with telling you what i know about her first,
k reg, jap import (no certificate :( ) it is registered though,got pulled over on way home lol, all legal lol.
has had auto to manuel conversion done by mechanic? this is what the previous owner has told me. also can tell by peddles has extra one for the clutch but Big brake.twin turbo,targa top, used to have cloth interior but previos owner swapped for leather,
when i drove her back from london some 150 miles it didnt miss a beat, no knocks,clunks,etc - it does need a new nearside front shock but told me that when i bought it, had to climb in through boot! as alarm didnt work and has no key for the doors only ignition and boot. fixed the fob now so all good again. needs new brake pads/discs,oil change, tyres,
since monday nite as ive been inspecting ive noticed a few things and problems.
it has manuel bleed valves on the actuators which are wound all the way down, want these gone and returned to stock. its only boosting to a tiny bit over the first fat line on the boost guage, it goes to +7 if that helps.
also my fan belt is squeaking but my bat is very low, power light flashes at me sometimes. gonna charge it tonight,
BIG ISSUE: i dont have a overheating issue, its always at just below half. but my system doesnt seem to hold water? no leaks underneath. but when i went to check the water leval, took the cap off couldnt see anything cos of the shape of that rad, so unsrewed that black cap on the drivers side of the rad. couldnt see any water? so filled her back up with both caps off, squeezing the hose to get rid of air,filled till over fill the small hole on drivers side, screwed the cap in, put the rad cap back on, went to work this morning,came home,checked again,still couldnt see water? one thing i have noticed, my passenger floor is soaked! heater matrix maybe, how can i be sure? can i fix without ripping dash out? also i looked in rad whilst engine running at temp, and theres very very tiny little bubbles, i hoping the this isnt headgasket? no excesive water in exhaust,or lack of power,well dont feel like it but my first Z, could this mean something else, if so can i fix it,
im hoping that by charging battery tonight, would i be right in thinking this would reset ECU?, it would return to standard boost? or fix my next issue, when running, if i lightly touch the throttle, like 1mm,it bogs right down but every rpm after its fine, like the bit of slack between the pedal and cable,tiny amount, make it bog, but runs fine?accelerates fine. even if i rev it under bonnet, just a touch and itl bog, or if i (blip) the throttle,bog then growl.could this be to the battery being so low? hmm?
last thing lol., when im going 3-6 mph,walking pace and gentle press brake, i get a rather comical Boing sound lol? sounds like its coming from the middle left,i can feel it in the peddle, press the brake firm i dont get it or hear it, or at more speed? any ideas what it could be? oh wait one more thing, ive got a grey rectangle plug just above pedals, he also gave me a cable with what looks to be the male end to it with USB on the other end, What can i use this for? i have a small green wire going into the ECU if it helps,but that could be for alarm maybe, viper alarm blue remote, aux function dont do anything just lock and unlock.
really sorry to go on and on and on. but this is one of my dream cars, and now i have worked hard to get one, i dont want my first Z experience to be a BAD one.lol.
thanks very much.
sam. -anyone know a good Z garage in shropshire?
OK,just got back from the nightmare! of trying to get back from work. its a mile or so down the road! ok i checked my fault codes last nite, had none,55, charged battery-reset ecu,and on the drive home, the car ran like a bag of S***!!! that bogging i was on about was practicly stalling the car, the idle was 2000rpm- 950rpm when it felt like it, pulled over, idle went to normal,went under bonnet, tried to make it bog from the throttle bar. no bog, fine, typical, hopd bak in,pulled out of junction, doin it again! steering went abit heavy,cudv bin my imagination cos its ok now? im getting stessed, can someone help me? maybe shed some light? p.s i was havin a peek around engine bay at lunch found dat my passengerside turbo elbow o2 sensor the wires next to the plug, one had a choc block and one had a split in the insulation, gonna try unpluging it after dinner, cant find the plug for the drivers side.
