Great site you folks have here. Just got a 1990 300ZX for myself here in the USA. Great car. I work at a dealership and it was traded in. Only 25,000 miles on it in 13 years! I had to buy it. It's burgundy no turbo 2 seater. (Sorry if thats not the right terminology, I'm new) I've been waiting for a "cream puff" sports car to come through for years. Anyway, the car is perfect except for the front. The guy drove on the highway and got a lot of rock chips. Should I paint the front of the car or leave it for the sake of being original? I don't know how much of a collector car it will be, and I always hate to break factory paint if I don't have to. A bra would…

hi i have the above named boost contoller. i understand that it is a bit ancient but it is all i can afford. anyway, i have never fiddled with it since i bought the car (it came with the car). i have no idea on how it shoukd be setup. i have had a look at the website for the unit but i am not educated enough to understand a word it is saying. can anyone help me set it up so i can get above average boost. i don`t mind travelling and paying A LITTLE for the time or any help over the forum would be appreciated. cheers guys. rav

Was talking to Luke a while back and during the conversation he reccomended bonnet venting as an effective way of aiding engine cooling. anyone here got bonnet vents and if so, do they help keep your engine a bit cooler?

And fancies doing a Z appraisal on Saturday? Drop me a line if you are...! Thanks, Doc.

Hi, I have heard that a company like Jun or greddy make one, does anybody know?

Anyone on here work in garage in Abington near Cambridge? Seen a black zx parked outside a few times whilst driving past.

Hi, I believe the japanese EGT sender probes all have the same diameter and thread and I wondered if anybody knew these specifications?

Couple more questions on my '90 NA 1) needs a new zorst, probably a full system, any recommendations? Back before I got into bikes PECO were the one to go for, but times change 2) Will probably look at freeing up the breathing somewhat, is an free air filter (eg K&N ) enough or should I go for a cold air induction kit? 3) Any other suggestions to enable a few more ponies out of the stable would be appreciated Cheers

Got Blitz induction kit and Mongoose Zaust what is the next stage!! car is a uk man tt and has covered 64k with recent stock turbos would like to remove cats but worried of the probs caused by this mod cheers Dave:confused: :confused:

Can anyone tell me whether the HICAS light being on (due to low fluid) causes HICAS to be disabled ? Regards

Just to be really boring.... I have the nice yellow alloy space saver that comes with the deflated tyre that cleverly folds into itself (kinda thing). Does anyone know a company who can replace this tyre ? Ta very much ! B.

Which pads for the front do you guys recon I should buy. Was thinking red stuff, what do you think.

When driving in pretty much a straight line for around 20 mins(motorway cruising etc) my Hicas light comes on and I seem to have to steer very slightly left to go in a straight line. As soon as i get to corners/twisties etc the steering rectifies itself but the Hicas light stays on until I turn off the engine - then when I restart everthing is ok again. I dont get this problem at all driving on normal roads (i.e. anything with corners in). Any thoughts?

Hi Zedsters, Sorry to be a real lame-ass on this one, but I've checked the archived threads and I can't find the information I need. I know what HICAS is (and I'm quite impressed with 4 wheel steer!) But I've got bugger all idea where I top the fluid up (HICAS Red light is now always lit on my dash) and what with (I'm such an amateur!). Also can anybody tell me how urgent it is to do this, coz I'm worried that it's gonna go all Pete Tong the longer I leave it. Cheers guys and gals

Looking to get my car serviced Definately cam belts/alternator belts need checking/replacing Give it a good once over What exactly does a proper service mean? What do i get for my money? Are there different types of service? How long, do they need my car? A day? Do they replace things like spark plugs, fuel filters etc as part of service? This is the only car I have, so not having it causing major hassle (work, kids) Please recommend a reliable and trustworthy mechanic who knows what they are doing Thanks for your support:D

My TPS is playing up, I'm going to fix it. Can some other of you guys tell me what your avc-r reads at idle for the throttle voltage, with Idle revs +/- 800rpm without aircon, engine warmed up. cheers, Jez.

My Road Angel (GPS) and AVC-R (input from ecu) match 100% The speedos are always out, but 100mph on my dash is only about 91/92mph on the others. This seams a bit much. How much is yours out, is this normal? Jez.

Are they any good? Some the colour match - jet black? The UK one's are slightly gray and look crap. Are they shag pile (like the jap ones) or just standard? jez!

Why pay big money for Plugs get a set of NGK BCR8ES or BCR7ES. depends on your boost setting they retail for £1.52 + Vat. they work fine and no power loss. We use them in our 8ltr big block chevy V8 600 BHP (more with NOS) 280ZX Drag car(8.49 at 168mph) as well as in my 300zx 18psi boost. been using this plug forever. So if the mechanic tells you this is Crap then you can see for your self at the pod or Avon park. the triple electrobe plugs and split fire type plugs are no better than the above we have tried them on the track and found NO power Difference.they are only good if you do not service your car every 10,000miles. mines done every 6000…

If I have an exhaust system fitted without cats.....do I need to reset the ECU? If so , how do I do it ?:confused: Cheers, F.T.

Does anyone know of any good leather upholsterers , i want to do my Z out i can get the leather cheap so that aint a problem i just need to know any good fitters out there

Watched someone do a three point turn in my car and noticed that the rear wheels didn't turn at all! Also the car's turning circle is is not much smaller than the Q.E.II 's. Is my HICAS knackered? The HICAS bulb works. However, I've yet to run a diagnostics. Cheers Jon
