HI guys n girls My car has the rear HICAS eliminated. I now want to remove the HICAS cylinder/controller thingy on the front inner wing I understand that i need to cut the metal pipe which connects to the HICAS unit (the pipe nearest the Headlight) and then connect it directly to the rubber pipe that goes from the Fluid reservoir to the HICAS thingy. There are two other pipes coming from the HICAS controller which are lower down, and disappear downwards into the engine bay. I guess these go off to the rear axle? What do I do with those two? Also will all the fluid come gushing out (ooh err) and do I need to bleed the power steering once i have d…

Was going over my zed with the bodyshop guy today, my front fenders are really rusted as is the tailgate, Saw that zcentre sell vented fibreglass ones, are there any benefits to fitting them over having mine repaired? And the glass will have to come out of the tailgate for paint, worth changing to a tub or plastic if I could find one? The old z's my trackday toy, so looks aren't important but I hate to see rust lol...

Now going to wash me car might even give her an hoover as well as im looking forward in our meeting tommorow. think theres about 6 or 7 potential cars there. woop woop!

So I bought a 1992 300zx TT Import with a slight misfire/hesitation and thought it would've been a simple fix. It seems not. I've replaced the spark plugs, the fuel filter, swapped out the miniscule battery for a beefier one and ran injector cleaner through the engine. The misfire occurs when it's cold and continues to do so until the needle is about a quarter in its travel. Once I boot it when its warmed up there is no misfire and she runs smoothly. Except for yesterday. It was late at night, and chucking it down with rain. Usually when all the components are warm the misfire disappears, but this time it was odd. When i put my foot down slightly the engin…

It would be nice to get my car onto a rolling road and be mapped and boost set to what the car can comfortably take. It currently runs 10psi with a decat, mushroom filters and a Mines ECU. A friend suggested a stand alone ecu, as the Mines one probably wont be able to be tuned. What does a stand alone ecu mean? I have heard Horsham Developments down South are good with Nistune... Again, I`m lost lol! Can anyone shed some light onto this for me? And maybe someone in the Midlands that has had experience tuning 300ZX`s Many thanks, Dan

I have been looking for parts to complete my zed and saw this on youtube recently. It is a Zed with a Hiro rear cover for the rear lights - see below. I already have the side skirts and rear arches, but want to achieve the whole look as in the yellow one. Do I start searching on the Japan Yahoo auctions do you think? Any help appreciated!

Hi guys got to get a new battery for the Z im picking up, whats recommended? Ive looked on euro car parts and the 2 im looking at are exide and bosch, whats best? Cheers

Any one got one of the double din surrounds off ebay from the states ,thinking of getting one but worried about the fitting ? http://www.ebay.co.uk/itm/400710191831?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I recently discovered that my Zed is still running the J-spec ECU so revs and top end are electronically limited. As such I can pull past 115mph (not that I ever would or do :blush: Trying to find a replacement ECU is proving somewhat difficult and the aftermarket parts are crazy money imo. I've contacted Whifbitz and Jim Wolf to ask for some advice. A mate advised me that I should also try you guys. The car is a 1995 TT Auto. It's pretty standard except for an Apexi Exhaust and Apexi Induction Kit. Are there any Welsh companies that can assist or should I order a Jim wolf ECU for $600 bucks? Regards Paul

Taking the zed to Demond tweaks to have the camber set for track use,does anyone know what camber we should be looking at for track use??? thanks

would really be interested to see what work you have done and what parts you have used and what the bhp and tq was in the end and what issues you had. just engine and exhaust intakes cam head work pistons turbos ecu tuning boost levels ect...not body work or wheels or or any think like that think it would make a good thread that people could benefit in the future when looking to do engine work for more power and would be of a good read.

Hey guys. Right, time to return this 300zx to life. In red are the areas I really need help. Car is a NASP Manual Heres the back story: Drove onto a guys drive. Parked up. Sat for 7 years and not moved (no idea of the Handbrake was on or not). I put a battery on it and it fired up no bother (drove it 300yards on tickover and turned it off). Only issue to report is a bad idle. Brakes weren't really seized. I now plan to service the car and MoT it. What I plan on doing for Mot: So far I've bought a cheap oil filter and some 5/30w oil from Asda. These are literally to put in the car for it's MoT. It will be trailered to the MoT stat…

i have a question with reference to oil pressure, if you have full oil pressure when car is cold then nothing once warmed up does this mean i have no oil pressure or does it mean the gadge is crap, and how much to correct this? please

looking for help on this as i can't find the leak, after rain i have a water inside the tailgate, only notice it when i lift the tail gate and it leaks out from under the palstic trims inside the lid, i have replaced the rubber gromit around the rear wiper, spoiler is a fibre glass version of the stock unit but looks like it's sealed all round, it it likely the rear screen could be leaking?

Looking at changing the exhaust on my 96 na lwb. is this different to the tt one. My own thinking is yes they would be a different diameter or something? but no compatable. was looking about the bay but they are all just state 32 lwb or tt, so cant see a na one?

Hi, has the method of adding a item for sale/ wanted changed recently, about 6 weeks ago i was using some difficult system which quite frankly put me off from adding any more posts, however when i went to add one today, it seemed its changed to a really easy to use, well thought out post page. Has it changed or have i posted it in the wrong place Rich

I'm right on the edge of ordering some new wheels from the States, but could do with some thoughts on the fitment before I fork out for them. I've seen them on a couple of zeds in this size, and I would like to have an idea of what is required and what to expect when it comes to fitting them on. I will soon have coilovers fitted and looking at adjustable arms. 19 x 9.5 et22 Front 19 x 10.5 et22 Rear Any input greatly appreciated :)

ive had an intresting read and had some fun with there calculater whith the weights and power ratios, and only once been in a ten second car once and now how fast a ten secound street car really is but hey heres dreaming a. have fun. oh it funny thou that with there calculater it would take a thousand bhp to get a standerd weighing zed do ten sec but only 500 to get to the 12.5 sec. made a nice read thou and enjoy. http://www.torquecars.com/tuning/10-second-car.php

Ok, so have the box ready and a ramp lined up. few things I'd like to know if anyone would be willing to give advice. Is there a guide on here which shows removal and re-fitting , cant seem to find one Is there any extra bits I would need? like gaskets? obviously ATF III which I have already. The filling part, im going to assume theres still some oil in it as when I moved it some came out of the end. so what is the best way to drain and re-fill the torque convertor? is there a filler hole for just the torque ? and the total amount of oil is 7.7 litres ? Thanks for all your help ive had recently with my problems with the box, never would ha…

Anyone with a good working series PTU they want to sell, as my new one is kaput!

Hi - could someone give me a list of what tools I will need to replace my battery. Seems like a stupid question I know but the car is 50 miles away and I'm getting the train tomorrow so need to know what tools to take with me. MOT time on friday, fingers crossed all goes well! Cheers

just wondering how much you guy have spend on you 300 on mods and just keeping it going I suspect many people wont want to say, the z is very good at emptying your bank account that I do know.
