Hey all, I've finally got to the root of my problem, piton rings blown and the piston is shot to shit. This has caused a very slight groove in the cylinder. Now, I'm taking it to a place on friday, having the cylinder re-bored, probably will only need about 0.0020" taking out, but this will require an over sized piston. If I only change the one, and make sure the new piston is exactly the same weight as a standard piston, can I get away without replacing all the other pistons? Surely the fractionally greater compression on that cynlinder wont make any difference, will it? Obviously all pots re-bored and a full set of over-sized pistons ain't cheap, so would like to get ar…

my car seems to lose power (very momentarily) when changing gear, is so minimal no one that drives it can feel it, only can as i drive the car all the time and i know its not right anyone got any ideas

sorry! have searched. am going to fit a dv soon. i know you have to remove the standard recuircs, then block them off. most people put their aftermarket ones where the standard ones. (where as on a 200SX people put them on the Hot or cold intercoooler pipes. anyway, can i just put ONE dump valve in replace of the standard one, and just block the other standard one off? or do i have to have 2, one each side?

Hi all, Just wondering if anyone has any advice as to how to secure the stock front bumper when using a front mount intercooler (i.e. side mounts and ducts have been removed). I've bolted it back on with what mounts are still available but it's a bit 'flappy' at the sides - just in front of the wheels. Suppose the same applies to aftermarket bumpers too. Not sure if it would self destruct if I used it as is... Cheers RobH

Well, after a few harrowing months of Zed ownership, it's nearly time to do a few bits of basic maintenance. I'm soon going to be needing some new tyres (mainly because whoever put on the wide wheels didn't sort the camber... grr...) and was wondering if there were any suggestions? I currently have Pirelli Rainsports which are as sticky as anything, but obviously wear quickly too. I've been looking through places like http://www.mytyres.co.uk and have no idea what to go for! I need 265 35 R18's rear and 235 fronts if that makes a difference. I was going to ask about oil, but I found a post where j1mmytt was whinging about someone asking another oil question... s…

I have seen in the past, a few people have had this problem. How easy is it to sort? Gonna try and do a home job as my dad is good at that sort of thing and can't afford to get it done professionaly. Any tips or pointer would be appreciated. The main thing im worried about is finding a close enough paint colour match. Its a pearl white but dont have a paint code as it has been resprayed. Not sure if its a nissan pearl or not either.

saw you this morning one behind the other i was in a heavy goods vehicle limited:mad: between jcn 5&4.

Hi there, My car has just started squealing when accelerating hard, usually when coming out of a T junction turning right or left, then continuing down the road (in a straight line) unless I'm very gentle. Is this wheel bearings or do you think it's the diff, please? Thanks for your time! Mr Pink

Some advice please....... Have I ordered the right parts from Nissan??....... the bloke on the parts desk didn't really know what I was asking for!!! Please see attached....... Should be the springs and O-rings. Cheers:bow:

Now that I have HKS actutors on my new tubs. I'm really liking the noise that make when coming off boost. ** Edit been told this is actually turbo stall and not the actuators ** Is turbo stall a bad thing ?. If so how do I get rid of it ? The problem I have is that I not only get the "Tshhhhhhhhhhhhhhh" from the dump valves, I also get the "BerrrDerrBurrrrllllrrlllrlrllr" (you know the sound I mean). I know you can tighten up the SQL's to make them only go off at higher pressures, but can I tighen them up to the point where they no longer go off ?, If yes, and I do this is there any potential problems I now have.

Guys, I'm a little worried at the moment. We have a club dyno day booked up for the 28th of this month. My Z is almost up to the 1st stage of running it in. It's almost done 500 miles with an oil/flter change done at 150 miles. the car has now done 400+ miles since the rebuild limiting at 3.5 - 4k rpm and running max boost of 4k rpm. I'll be doing an oil/filter change at the end of the week when it has done it's 500 miles where I'll be putting some decent oil in. Since the last oil change, the car has not burnt any oil at all (which I think it quite rare on new builds - hopefully this is a good sign). It's not lost any water or any fulid for that mat…

hi again all i am thinking of de catting my 1990 n/a as the exhaust is rotting and will need replacement i have been told that cars registered before 1992 does not need cats for the M.O.T. anybody have any idea on the legality of this ie if the car was built with cats do they have to remain on the car? thanks

I've just had a new key cut as the other one snapped but it has now caused some problems. The key turns ok and the engine starts but when I turn it off and the key all the way back most times all the ignition lights stay on. It then take 5-8 times of turning it back on and off again until they go out. I can even take the key out of the ignition and all the lights are still on! Is this just because the key is crap and I need another one done?

What's the weight of the standard S1 2+2 tailgate and bonnet? Can i fit aftermarket disks/calipers meant for a TT onto an NA? Cheers

My Strosek Z is now at the bodyshop being prepared for painting. I am now having a crisis over what colour to paint it!!!! It is Black at present and i was going to change the colour to something like a metallic or Kandy Blue but i am now thinking it will look good in Black again! I want this to be something a bit different so if i do decide to keep it Black is there any paint effects that people can reccomend? I am really struggling and i need to make a decision really soon!

Do Turbo front and rear brakes fit directly on a N/A I have searched but I have not found anything that says it clearly. Thanks in advance :)

My car went in for an MOT today. It passed (phew), but on driving back I switched on the aircon and was promptly blasted with hot air. It was working fine on the way TO the test centre. The only strange thing I notice is that it looks like they disconnected the battery. Not sure why they would need to do this, but the temp on aircon was showing 10 degrees (default) and time was wrong. Anyone got any ideas whether this might be the cause, or what else might be? In this weather I'm getting a serious case of Betty Swollocks.

Im currently sorting out insurance quotes and confused.com have confused me. They cannot find the reg of the car to find its details presumably due to it being an import. My car is a 1990 TT Manual and the options available to me are '300zx Non Turbo', '300zx Turbo Coupe' (90-94) or '300zx Twin Turbo Hatchback' (89-98)and a few others. Now i didnt know there was coupes and hatcbacks and iv searched google images and cant find a difference, also I assume that '300zx turbo coupe' must mean twin turbo mustn't it? Anyway iv had quotes on both and for '300zx Turbo Coupe' it was half the price of '300zx twin turbo hatchback'. Can I just put that mine is…

Nice looking Zed with tops out, i was in the wife's BMW as it's a little hard to get 3 sets of golf clubs in the boot of a Zed! :wack:

Is there anyone on this forum running one of these Methanol setups? http://www.z1motorsports.com/product_info.php?products_id=1538&osCsid=12c7b3cbf2e45e436f55e1f8c9566544 I know the fiat coupe members used this alot on their turbo cars.

First time I've seen a Z on the road for real in ages, didn't have time to see the plate or recognise the driver as I was southbound.
