Yes, my car sounds like a sad old vauxhall cavalier everytime I start her up again! Squeeky belt syndrome is not what I want to be recognised for! I had new belts fitted in the summer and after a few weeks they were squeeling like Graham Norton at a Chippendales gig. I had the belts re-tightened and now with the recent drop in temperature (perhaps?) they're off again. 30 seconds of horrendous squeeling from start up and then they're ok till the next cold start. Is this normal?????

yep its the old detonation again!! modified the zed with:- se-maxiflow twin pop intake turbo technics 13.5 psi 360 degree turbo's de-cat & stainless exhaust cat back and ofcourse the se-chip!! running this set up i hve had detonation which destroyed my last engine so i dont fancy it happening again! runs fine with the standard chip but with the se-chip i get detonation where am i going wrong?? any help appreceated cheers dewi ap

Run a search and couldn;t find an answer so, How much oil will I need to put in her for a complete oil change?. Oh and where abouts is the drain plug?. Cheers.

My radiator cap is knackered - the rubber seal is shot to bits but not bad enough that it loses hardly any water at all - however when I stop the car I get a bubbling noise behind the dash board - My theory is that the system cant get pressurised enough due to the bad rad cap and is allowing the water to boil when the engine is turned off and the water sint flowing.. .I also reckon it may be allowing parts of the engine to run hot. Anyone think this sounds about right - or any other offers of ideas? Thanks.

Hello Who has got speakers mounted in the rear here?: What size will go there, and how much space behind the trim is there? And are they instead of the stock rear position or in addition to? Thanks for the pic Kirbz...been wandering round your site - very nice :cool: Cheers Pete

Removed the front end of the convert and fiddling around with the air intakes!!! Noticed after the airfilter as each pipe goes to each bank, there is a piece of pipe that ataches to it and bypasses the air filter and goes straight to the air inlet? What is this for?

Hi ALL, Looking to buy a 300zx myself soon :D friend has one (1990 TT) but the boost gauge dosent move on it at all just sits at zero (unless he switches it off) what pressure do the turbos run at normally becuse his one the gauge only ranges from - + 7 i thought the gauges ranged from - + 14. Can anyone help?? thanks

Well guys I am back with more problems on the Zed, but I guess these are my own fault for testing out my top end on a certain M road!:slap: Well, I have water leaking from somewhere, when I look under the car, it looks like is coming down around the gearbox area, any ideas???? Could I do this or anyone help me??? Also, a metal rubbing noise coming from the front drivers side which you only really hear when you go over a speed bump or a rough road. And also a fuel leak from the round funny thing that sits on the left hand back side of the engine with 3 pipes connecting to it which should be easy enough to sort. ANy ideas on any of these guys??:confuse…

Hi, not probably the right place to ask but I know how knowledgeable you guys all are. I need a link to a wioring diagram for a MR2 turbo or SW20, whatever you wanna call em. I need it to fix a problem with my central locking so I can sell it before my Zed arrives from Japan. Many thanks, Justin

Where's the best place to mount the solenoid for the Boost controller. I know it should be within three feet of the turbo's but I have also seen people mount it over by the hicas set-up. Where have you guys mounted yours ?

Any volenters to come fit this for me?????? PLZ PLZ PLZ. I fitted it to my 200sx and that was easy but just cant seem to see how to put it on the Z even after looking at some instructions on here. £50 cash waiting and unlimited cups of tea with bacon sarnies.

I'm looking to improve the bass in me car, so I've decided to get a sub. But I know next to nuffink about ice, except it makes ya drinks cold!! So.... Do I need to buy an amp to run a sub? Can I just buy any old sub, or do they have to be the same make as the head unit? WTF is an active subwoofer? How does it differ from a normal sub? If it helps, my head unit is a Sony Xplod one! All help and suggestions gratefully recieved.. Malibu:dance:

It looks like im gonna be needing some pistons/rings for my Z. Has anyone seen any good deals for cheap ones/good ones/both? Best i've seen so far is JE's for £460 pistons, £70 rings and shipping which i have yet to check, but am guessing at around £100? All help greatfully recieved. Thanks. si

I am referbing my calliper and have striped it down, only problem is I have split the calliper not realising that I should not have split it. Acording to the online manual I should not have remaved the bolts holding it together. Have I done any serious damage to it by removing the bolts? Thanks.

I have bought a manual gearbox for my conversion and i want to know from what year is it.Is there a way that i can find out?

hey people, something i need to clarify is that if ever someone has a plugged PCV valve in their 300zx TT, would it cause a leak in the main seal by any chance???

...on a Jap Auto - I have purchased the centre bearing - is there anything else I should change whilst the car is in the air - Gearbox mount perhaps? Any help/advice appreciated? AndyGP (andy@viewscast.com)

I am sure some of ya have seen a Mines ECU in the For Sale forum. Any one got any experience with these and how do they vary from say just having a JWT or SE chip? I am looking for a mod like this so I can get an electronic boost controller and up the boost. I guess it would need to be remapped to go onto my Zed. One problem with it is the guy selling it comes from Australia, a bloody long way to go and have words if it doesn't work! Do you think it would be risky to go ahead and buy this? Many thanks, Justin:)

Hi Paul, Just going back to the RR day! Noticed they had a bit of trouble sorting your BHP/RWHP figures! Out of interest I know the Gtech meter you have gives you RWHP figures for your car, how did these two sets of figures differ!

I have recently changed engine of my z but when it deccelerates it stalls or it revs at idle from 200 rpm to 2000 rpm. My mechanic has found that there is no signal going from the ecu to the fuel pressure regulator. When the fuel pressure regulator is given power indepentenlty then the problems seems to stop. (power to it is given straight from the battery randomly). Any ideas why the ecu is not giving power to the fuel pressure regulator? the ecu was fine before engine change. help!!!

The starter motor on my '90 300zx manual Jap NA decided to pack up today. Two questions: 1. Can I use a starter from any 300zx, ie UK or TT spec? 2. Where can I get a recon unit from? Thanks, Colin

After talking a freind of mine out of a clifford alarm he's thinking about a scorpion, has anyone got one fitted, do they do their jobs with minimal problems?

Hey guys, hope you can help me out here. I have a 300zx Twin Turbo which has a leak underneath where the tanny and motor/crankshaft meet. Now i am more than certain that it is my main seal that is causing the leak. But one question i have to ask is whether i can use the "ADDITIVE" to perhaps expand the rubber seal which can possibly stop the leaking.Please let me know whether that is advisable to use or not because replacing the seal is costing me an arm and a leg and possibly my nuts aswell depending on where i go to fix it. Thanks mates and cheers

Hi Guys Last couple of days I've experienced an alarming power loss under hard acceleration. It happens particularly in 3rd and 4th gear when you boot it to the floor (eg: overtaking). All of a sudden the revs drop and it feels like I've taken my foot off the gas, lose all boost etc.. Take foot off the gas then reapply, and everything seems back to normal :confused: :confused: It doesn't happen all the time, but I've experienced it twice tonight! Any ideas? Cheerz Steve PS. This is not just a crap excuse for my rubbish RR results :p (although maybe it has something to do with it...)

anyone know how this system supposed to work, is there any write up on it takes a while to warm up and always blows fast speed when you turn ignition on
