The last 2 times i've been round to start my 300 the hicas light has come on but gone back out after 5 seconds any ideas why?

Right.im getting the ashspec 2.5" inlet pipe kit that goes from the turbo on the intake side to the air filter.now this peace of kit cost $395 US. now i will be going to larger fmic and pipework but do not wish to spend onother nearly $700 us on pipe work .and also on pipe work that ill only half use.and goes aroind the houses. So my idea is to get the intake pipe kit as i said and only the first part of the intercooler pipework that comes from the turbo to the intercooler.this pipe is called the turbo discharge pipe.now, normally the pipe that comes from here is a two" pipe .that joins on more peaces of 2" pipe.now because im having my new tubs fitted soon.it will.be…

Right then. I have a slight misfire that is worse sometimes than others... its Fine at higher rpm but only really at idle It's noticeable. Could this be a O2 sensor... checked the voltage and one is like .20 volts lower almost constantly. Could this be the culprit?

I was driving buses around Eastbourne yesterday and saw a ZX near Victoria Drive near the row of shops. Looked good and pretty OEM. Was it you? Mine needs a friend to chat with so let me know!

Went to Croydon today with the aim of picking up another zed, to strip the engine for my yellow one and a few other parts for both my zeds, but starting off, getting a train and having to change twice on the way up, due to signalling and other problems was a pain in the ass, the guy picked me up from the station and off we went to his garage. I get to see the zed on the ramp to have a look underneath, shabby is an understatement, lack of care would describe it politely. Fitted with a HKS super drager single exhaust and i cant believe that the back box is stainless and the rest of the pipework is steel to the cat pipes, with more holes in than a cheese grater :thumbdo…

Went on coastal drive to Lydd Then back to Folkestone fast route via Ashford M20 !

like this idea. The conbination of a wide band sensor and a boost control all rolled into one little neat gadge.heres an explanation on youtube. and for about the same price as a wide band monitor or a boost controler.feels like you getting one for free.and less clutter in your car.views please.could well be my next purchase.

First proper drive of my zed tonight and impressed pulled well and autobox seems fine. Surprised how quick it builds for a big heavy car :) still need to do a compression test on Saturday but if low compression while cold on pot 6 it feels fine when warm lol. Can wait for weekend to take it for a longer drive:)

Shot past me during today's afternoon rush hour looked tidy

Hello, i have a 1990 300zx TT with a manual conversion (original UK model) i have done some engine work on it by upgrading the injectors to 555cc with an apexi boost controller among other things, i was supplied with a "generic" chip by the person who socketed my ecu for me and he told me to talk to Nel aka NOS to find out about getting a custom ecu chip made for the car. It currently runs but badly, i have gone through the engine and tried to solve problems such as vac leaks that could cause the issue but have now come to the conclusion that it isnt broken it just needs setting up properly.

So I've just had my Shortie hooked up to Conzult (hopefully a truly worthwhile purchase!) and I'd like knowledgable peeps to have a look at the attached screenshots and tell me if there's anything I should be concerned about please :) Cheers!conzult1.doc conzult4.doc conzult3.doc conzult2.doc

Have a misfire problem. Misses at idle and when cruising off boost. On boost still pulls all the way to the redline. Also when coming off the throttle when not under boost it seems to cut off and stop abruptly and launches you forward in your seat (rubbish explanation I know!) Symptoms also are worse when the car is cold. Any ideas?

Anyone recognise this? Found it while doing stuff on my car today

At around half 3 I decided it'd be a good idea to go out in this Arctic whether to try and take my BOV'S off the car and go back to stock recircs. 2 hours later and I've only done one side (passenger). What a nightmare it's turning out to be. Probably wouldn't be too bad if I wasn't trying to do it on my driver in the freezing cold. I couldn't move a bolt on the other side and the head snapped off one of the camps so I gave up for a while on that one. Unsure if I could use the car now until it's finished as I'm guessing one BOV and one recirc would be a little weird. Anywa, got me wondering, what jobs that you thought would be easy was actually a pain in the…

OK simple before or after? Before: Or after:

I wrote off Jan's Zed on Thursday. Got a few cuts and bruises and big pain where the seatbelt diagonal was. On the A64 on the Malton bypass. There's a long drag up an incline, then it goes into a right hand bend and just before the bend ends starts on the downward descent. About 500 yards further on is a layby where a camera van hides sometimes. I came up the long drag slowed to about 50 - 55 foe bend and was looking for the camera van when I hit an unsalted outside lane full of snow and slush and ice. Well it started to slide I corrected but I must have over corrected or something because it went off the road and the all hell broke loose It demolished a s…

Just want to say a big thanks to Mark and Noel,Mark fitted a replacement engine and Noel mapped it,car drives great.

Hi guys, just been and viewed another 300, I have fairly good knowledge of the cars, the turrets, floor and boot look to be solid. There is quite a bad patch of rust above the windscreen, how difficult can this be to repair? I presume the windscreen would have to come out? The car has sideskirts and from what I can see the rear sills seem OK, however there is some bubbling at the front of the sills inside where the door shuts. Sort of on the top of the sill and below the hinges. Is this common, I haven't heard of it rusting here. At the back, yes, but not the front. I know it's not a lot of information, but I don't have any more, any help would be appreciated, even if…

Had a good look around and found a few but although theres not much diff if design.but there is a $100 price diff though.whos got what if at all diff from stock and from where. AMS.2.5"$299. Or. ashspec. $395

Well bad news just been told the zed I have bought has a low compression on cylinder 6 when cold 75psi then builds up when warm, wonder if this is the noise Iam on about as well:( seems to pull ok but give it any right foot really. Bet a engine rebuild won't be cheap :( bugger bugger

Remember the 300ZX trip in France with a 944 and Capri? On BBC 3 now!

Does anyone know what size the outlets are on the HKS style FMIC are? I know the godspeed ones are 2.5"

What grade oil are people using in there zeds, it was changed in December looks clean but I don't know what grade was used so might change it gents. Cheers

Took a vid of the engine which you may be able to hear the noise which could be a bearing or something or do these engines suffer from dry tapets? cars not done many miles in the last year and I haven't had time to drive it any where. not one for taking vids on phones or I pads as makes it sound worse lol. http://vid280.photobucket.com/albums/kk200/m_reed2008/IMG_1956_zpsb4epiytz.mp4 hope it works.
