I've never seen the needle on my tacho climb so quickly since it was fitted. (Except when my old clutch was slipping!) I'm well happy :o) Dave

hi m8ty i need your address to send you the rs owners club magazine i have with all of the contacts regards the pistons we spoke about

Hi all - possible stupid question here: Is there such a beast as a single-turbo 300? I'd never heard of one until I recently found someone's site that listed masses of performance cars. In the Nissan category it had several entries for 300's by year, but actually listed three different types, the NA, a "300ZX Turbo", and the TT. The performance stats for the 'single-turbo' where about halfway between the other two cars. I wouldn't have though much of this, but I recently saw a car at a dealer that didn't have the TwinTurbo badge on the back, but did have the boost gauge on the dash. Any ideas? Raz

Above No plate for sale. I have it on paper; not on the car (if it makes a difference). Paid total of 600 something £ myself. Sensible bids entertained. Cheers.

I have a 1990 import Non-Turbo and want to change the oil soon.What weight of oil should I use?..Also, how much oil does the engine take, including the filter? Any help would be appreciated..JEZ300Z

Hi, A friend of mine has installed a HKS EVC4 boost controller in my Z. I have 2 questions : 1) In the HKS installation instructions, it does not say anything about disconnecting the stock solenoids, but on some web sites, they say to disconnect them. HKS say disconnect them if you are 'underboosting'. What should I do ? 2) The HKS EVC4 has a switch on the back labelled SW and PO. HKS say 'SW' is for a single port, swing valve or internal type wastegate and 'PO' is for a dual port, poppet or external type wastegate. What should I set mine to ? Any help appreciated. Thanks.

Hi, Not sure what happened on the previous post, my aircon is not as cold as it used to be how do I tell if the refrigerant needs topping up, and any idea of cost

Hi,

Hi,

I have for sale a front and a rear bumper from a 1990 TT 300 import (so the mounts for number plates are Square). Both are in reasonably good condition and are in red (Strosek replacements are being fitted). I also have an auto-box, propshaft and torque converter. All are making way for a manual conversion because the auto had a problem where you could drive for 100 yards or so and then you would lose drive. Turn the ignition off and start again and everything would be fine for another 100 yards. I don't know if the problem was with the box or the electrics, but a spare box for someone might be useful. Any offers or queries e-mail me at pauls@pstorr99.freeser…

the fuel filter back to front!!! I had a major service last september and the mech installed a new fuel filter as part of the service. Ive only just noticed. Could be contributory to the detonation & low power at high revs problems if there is fuel starvation. Just replaced it. Q. I am looking to replace my plugs. I am currently using Bosch/botch Platinum LOL. Has NE1 had problem using these plugs before? Trying NGK PRF6B - ? (11b or 11c) C is standard and I think b is a cooler plug. NE1 using them? What do you think? Running 13.5 psi so I guess a cooler set of plugs are now needed? Im also going to try some of this Redline Wat…

check out the karting info in the news section. As of tonight, there are only 9 driver spaces left, and i have 3 possible drivers who will confirm on Tuesday, and 1 north london driver whose money is on its way i think. That may only leave 5..... All spaces are first come first served. So email me for my bank details, and you can get your place secured. craig@avnet.co.uk I might try and arrange some more places, but the downside to that is that we all get less tracktime. So 20 is the ideal number. As i sure as heck want as much time on track as i can get, without paying for two spaces :)

Chaps: What can cause this? Cause I seem to have it :-( /\/\ark

I am 23 and have been saving for a Jap super car for 3 yrs. I had settled for a Supra as a 300zx seemed out of my league. It is looking like I might be able too aford a Z so I would like some guidance before I make the leap. Could I expect to get a reasonable car for £5K ? Would a budget of 1K a year be enough to keep your average stock model running nicely (servicing,maintance and repairs)? Are there many Z friendly mechanics around Swindon? Would you seasoned hands still talk to me if I held off on the mods while I got used to the car? Thanks, Phil.

I have just tried to finalise my purchase of the HKS modified ZX, when the dealer put the paper work to the finance company they came back and said that they would only go up to 10K on this type of veihcle, this was the same response from several companies. Has anybody had this problem before and can somebody recomend a finance company that will take the ZX on board, they seem to think they are very specialised car and are nervous.

Hi guys, While I was sitting in traffic this morning I was wondering does anyone know what the maximum RPM is on a standard Z32 TT with the speed limiter removed? Can the VG30DETT handle 8000RPM+ safely or would it need stronger internals? Thanks guys, Trev.

I am a new joiner, and currently awaiting delivery of my car. The car is an imported short wheelbase 2 seater Fairlady Z twin turbo of 1994.7 origin. The model has the slightly higher set spoiler. I am concerned about the siting of the rear fog light, and agreed to have an external one filled under the bumper, rather than have the bumper cut at this stage. I would like to have a better job after delivery and would like information about the fitting on other member's cars. Can the rear cluster be modifier/replaced, or is this not legal. Is the only option to have twin rear fogs cut neatly into the rear bumper, as I see on some of the member's pictures? Thank you…

I am using s-unleaded with castrol octane booster which has stopped the detonation. Is this OK to use? I know anything has to be better than detonation but does anyone know of any long term problems that this might cause. Besides the stuff being bloody expensive. Thanks, Andy. PS. thanks to Rowan for all his help.

Evening, With all this talk of removing cats, I was wondering if I would receive any added performance with my normally aspirated Fairlady. It's a K 92 - is that just out of the age bracket for doing it legally? Cheers, John

Just heard from my Nissan dealer, I need a new 'front crank seal', gonna cost me £225 fitted. Ah well every cloud has a silver lining, I've been meaning to get an underdrive pulley for ages. Will the crankk pulley have to be removed to fit the seal, in that caser I suppose my new pulley will be installed for free? Dave

I have just been told that i will need to upgrade my brakes as i am running about 350bhp to Tarrox 6 potts then i will need to change my rimms to 18" to accomodate, is there not a more intermediate upgrade i can go to from standard brakes

Hi, I am considering buying a zx tt at the end of the year when as I have decided to get rid of my company car (ford mundaneo, nuff said ..) I have read that the auto is preferable as they eat manual boxes. Is this true? I would prefer a manual to an auto. Any comments?

Can anybody help me, i am looking at a 300ZX with a series of HKS mods, there are two small boxes in the glove box with various buttons etc can anybody identify what these may be, all the dealer can tell me that it has been modified to aprox 400bhp with s/s exhaust system inductor kit, blow of valves but still running on stnd wheels & brake combo any advise and imput much apreciated. Tim.

Rough acceleration and idling (minor). But cured when ECU is reset. I find that the running of my engine becomes rougher over time but everytime I reset my ECU (disconnect battery) the engine runs so much smoother and revs cleaner especially at higher revs! It then becomes rough again so I reset the ECU and so on .......... The boost remains the same etc. I thought the ECU learns and improves the running of the engine not make it worse. Any knowledge in this area? For those who are having probs or havn't ever done this I suggest you give it go and see if you notice any difference!

Thinking of possibly doing away with my cats. DP Motorsport have quoted me £70+vat each for cutom made testpipes. This also includes 'flanging' my cats so I can swap 'em over at MOT time. Could I also gut the precats and remain legal? (I have a '94 model). On the subject of precats, I remember reading that the Z only has a precat on the left hand side as there is no room for one on the right & that pre 92 models have no precats at all. Is this true, or did I dream it up one night after a *couple* of beers? Dave
