Just looking at getting the most from what I've got at the mo.. I'm currently running Blitz induction, An upgraded ECU and Japspeed cat back system. I'm not sure if the boost has been tweaked as i don't have a boost gauge. With this in mind what's the optimum octane to run on? I always use 97 ron minimum and occaisionally 99 when its convenient. I can't really tell any difference between them. Certainly nothing like the difference in performance compared to running the Zed on a cool night, rather than a hot day.. Obviously there are plenty of ways to boost octane levels further with fuel additives, but I wondered if it would be worthwhile? If my car has bee…

Got my mint uk spec clocks today a must mod for any jap motor. Very pleased and also pleased with the advice given to me on servicing my brakes and the free bleeding pipe supplied to. Also seen Richards car looking nice and a very nice white zed with cystal rear lights which looked very good. For the price there a great update on the standard zed lights IMO Damo j:thumbup1:

Although the basestock of an oil will be a major determining factor in the lubrication quality of an oil, chemical additives play a major part in making sure that it does all that it is supposed to do. The chemical additive package of an oil is just as important to insuring the quality of a lubricant as is the particular basestock used. The chemical additive package of an oil is designed to perform a number of tasks and each task is performed by a particular type of chemical. The quality of the chemicals used and the manner in which they are blended plays a large part in determining how well the additive package does its job. As the quality of the additive chemi…

This is something different but well worth reading. It was written by our learned friend in Stoke and we think is of interest to any car or bike owner. Well…………! In The Beginning there was Carbon and Hydrogen. These got together in accordance with rules forged in the Big Bang (yes, really!) to make methane, one carbon atom with 4 hydrogens stuck on. A bit later, (only 4000 million years) other atoms started getting together and finally came up with Life, a self-reproducing chemical mix. The reproducing bit was quite fun, but after 600 million years even that gets boring. So, a more or less intelligent life-form invented The Car and the Motorcycle, th…

hi all . the zed has started idleing a little erratically . it seems to be hunting a little and after a while she cuts out . starts again straight away but if left idleing will cut out again . on the to do list are ; change fuel filter pcv valves . poss fuel damper ptu for a series 2 when i can get the sub harness is it possible that 1 or more of these could help with the problem . another problem that she has is hessitation on initial pull away but none whilst driving . any advice or pointers will be gladly recieved . cheers andy

hi there ,whats best intake air temperature (after intercoolers ) .?

Does anyone know of an easy way to bypass whatever stops the key from coming out unless box is in park. Sometimes mine does not release and can take me ages to get it to. Great idea when its working. F*****g frustrating when its not working. Always does it when I'm in a hurry to get out. Thanks guys. :thumbup1:

Hey all, just wondering possible causes for an irregular idle could be..? Most of the time it idles fine, but sometimes its at around 2k.. this isnt just when its cold either, I was in traffic, at some points the idle is 2k 2 minutes later its normal..? Is this anything due to the fact it has a viscus fan and the engine was hot? (never had a viscus before) I did have some issues a few days ago regarding some bucking and juddering when driving normally, but these stopped during the same journey, I have since cleaned the airfilter too, but in an attempt to take it off sheared one of the 4 bolts (the fixings are all horribly rusty in there), so its possible its recievi…

just noticed that others cannot post in my journal and that i cant post in some other peoples, is there a setting that i need to change or is that just the way it is?

In Battersea area 2 nights ago red zed swb Mid level spoiler L reg very nice JJ:tank:

Anyone remember seeign these? Its a short piece of loom that goes between the ECU plug and the ECU so if you are hacking the loom then you can hack into this. Trying to get hold of them as an alternative, neater method of wiring for the Emerald conversion. On Pete's I gutted a stock ECU and used that but would rather use the extension if possible.

Virtual pint to whoever can see what's wrong here:

Just a quickie, to say thanks to Jeff, Jamie and the boys at zedworld, for getting my pride and joy back to me, all running great, and lookin good...:gunsmilie: She's driving great, pulling well, boosting as per normal, but every now and then, at a standstill there's a few puffs of smoke from the back... I realise that this is more than likely just oil burning opff, or whatever, but I just thought I'd mention it... :sleeping: Other than that, I'm a very happy chappie, thanks again lads, and I'll see you for the service in a few weeks... :cool2:

can anyone tell me why a uk spec reads from -14 to +14 and a jap spec reads from -7 to +7 are there any differences with the standard boost . cheers guys andy

hi all the zed developed a strange misfire today dont think i missed it when i bought the car but anyway rear cylinder passenger side bank was missing i swapped coil packs with a working cylinder and misfire was still present i then removed the plug it felt tight in places when loosening it but looked ok nice grey tip etc i then swapped it with the plug from number 2 cylinder (so rear cylinder now has coil pack and plug from number 2) and it's now ok any thoughts what it could be? originally when i found the fault removing the connector from the rear cylinder coil pack made no difference to the engine running (i 'e missfire showing up)

:confused1:i had a weird idle which upon investigation reveled i had a misfire on the drivers side front clynder. ive cleaned the injectior connection, done the screwdriver test, and it was clicking, ohmed the injector which came back with 12.9 i believe this is acceptable? ive also checked that i have a spark swapping the coil packs made no differnce and i pulled the plug and grounded it to the plenum and i got a nice fat spark. the plug itself looked normal no blackness or chunks missing etc. ive cleaned the ptu connections. all im thinking now is taht it could be the injector connector is so badly corroded its past salvage? any advice greatly recived my mot is due this…

After years of living on the coast with the previous owner, my Zeds engine is looking pretty grimey and full of baked on sand and crap. I've managed to clean what i can using engine cleaner and elbow grease, but it still looks a state. I was thinking about getting the old jet wash on it, but i'm more than a little hesitant. Even with electrical connectors wrapped in film and protected from water i wouldnt feel 100% sure about it. Has anybody ever cleaned there engine this way? or any other tips or tricks?

Hi guys, Going to Dorking trhough work until Christmas at least so, do any of you know of anyone in the area that's recommended to spanner Zeds?

Hi guys, took the car out for the first time in a few weeks, first stop as ever the local garage as Iv got a couple of slow punctures at the back. Anyway garage is only 2 min from the house, get there leave the engin running and start working my way round all of the tyres. When I finally get to the front left there is a nice puddle forming in front of the wheel. Obviouse question from the mechanically inept like myself, what is the likely culprit. Thoughts and advise as ever appreciated. Cheers Martin.

This should be very simple for one you but not me :) I am after the green injector conecters but dont know the name or type of them, if i use google i get eveything but the one im after....... anybody please?? Ta

hello. does anyone know where i can find the tutorial for the seat belt as the belt doesnt always adjust itself accordingly. i've looked everywhere on the site and cant find it.

Saw you last night (Sunday). I was driving the burgundy Audi A4 Cabriolet in front of you.

How important is it to buy fairly decent quality REAR brake discs for a fast road occasional track use car with r33 gtr brembos? Say for example, standard ebc discs @ £111 or dba 4000 @ £280. I have the dba 4000 on the front and cant decide whether to match the rears or save some money and get the cheapies. Maybe its false economy and i'll not only be sacrificing performance but the cheapies might wear alot quicker? Any advice welcomed :thumbup1:

I have done a search and found no answer to this other than the possibility of a mouse living in the car..? Anywho, the problem is when I press the clutch down I get a squeaking/clicking noise like I am pushing against a squeaky bed-spring or something... it's quite annoying and was wondering if anyone has any remedies and can point me in the direction of curing this problem. Many Thanks! André

Car mats?lol. Going to get some new ones, the original shagpile ones are abit of a pain in the ass nowadays. Seen some nice heavy plain black ones in Tesco that where nice. So what do use guys have? Craig
