My Twin Turbo has a misfire on cylinder # 4. Me & Mikey Bean had a look today to try and resolve it, so far we've tried changing coilpacks, spark plugs, PTU, cleaned up coil pack connector, can hear injector ticking like all the others. Where can I go from here? Can someone give me an idea of what to try next please? Got bits kicking around if I need to swap things like ECU etc. :shifty: Any input would be most appreciated thanks :thumbup1:

Well car was fine yesterday, today strange notchy steering like it keeps getting snagged on something when turning, checked the PS pot and the correct amount of fluid is in there, checked the tyre pressure and although my passenger side was slightly lower than the drivers side, pumped it up and still the same, could this be related to the steering arms and my mysterious clunk i have at low speed?

Hi does anyone ever fit the T28 turbos from a 200sx s14? Surely it's not that hard they both use same exhaust flange T25 then use the s14 elbow which uses 3bolt to down pipe my just need a little fabrication to meet elbow to the 300 down pipe? The reason I ask is a friend has 2 T28rs turbos and I can have them cheap What do you guys think? Paul

Does anyone know of anyone in the middlesbrough area who can diagnose and set up 300 zx seem to be struggling to find anyone in this area .

Whilst trying to remove my aircon pump i lifted the brackets slightly to move the radiator over and snapped off the plastic nipple type thing on top of the radiator. I can see inside the radiator now. Could it perHaps be repaired somehow or would the radiator need replacing? It,s a na auto radiator would any z32 radiator work?

Hi All, Just about to refurb my R33 Brembos for the front. I was gonna paint them or powder coat, but would like them all to match. Do I need the Brembo rears? Are they any better than the stock? Cheers

Hi everyone, My next major job is a small ICE install. Does anybody have any hints and tips for the false floor? If anyone has a template that would be even better. Cheers, Rob

My mate works in a little garage on Thornaby industrial estate, and he tells me he's getting 2 300's in to do an engine swap, was just wondering if it belonged to anybody on here????

I think (fingers crossed) ive found the cause of my smoking at idle issue.........i dropped the oil out of her yesterday and it was as thin as weasel p*ss!!!. it was castrol edge 5w40 fully synthetic and has been in for approx 1800 miles but when it drained it did look or feel any thicker than brake fluid!, and thats no exaggeration, and had appeared to have completely broken down. refilled her with 10/40 semi and fitted a new filter, drove home (approx 12 miles) and left her idling on the turbotimer for about 4 minutes........and no smoke :) , whereas the night before it was billowing out :(!!!. going by the state of the castrol that came out i would never use …

ok i bumped in to some one at japfest he started to talk to me about getting more power out the engine by adjusting the throttle body's so they open all the way ( flap 90* ) to body now i seen what he showed me what to do but Does it ? as i thought it was strange seems i haven't seen it on here any ideas / thoughts on this

this must be one of the daftest things nissan did designing this car . allowing the rear drainage to discharge into the sills . ive recently discovered the dreaded metal cancer around the rear drain points . while cutting away the corrosion i decided to reroute the drains to a safe place where they cannot corrode . firstly i renewed the whole piping from the targa right through and then made a new exit point . the original drain tubes at the sill are going to be removed and the gap closed . heres some pics of the new set up . an easy and cheap job that could save you plenty . only costs about £5 a corner

Story starts 2 weeks ago when car up on ramp having tracking done.................... Looks up and thinks oooooo that looks a bit rough, so pokes it with my thumb, thumb disappears ! Decides today to have proper look and see whats needed, following was done without the aid of tools, just said thumb and a few fingers...... got new outers on the way and hoping can patch up inners as they dont look too bad ?

I got a massive task. As somebody know I am trying to tune my zed and i got some problems. I installed 555cc injectors and i got chip to run that fuel from AndyP But problem is that i spend 2 days to try fix over fueling and it was unsuccessful. Its over fueling badly cylinder 1 and 4 doesn work but tasted for small runs and its run good on higher revs than i put it foot down. Its spins wheels and its runs fast. But on 1-3 k revs two or one cylinders doesn work. Please give me advice why is over fueling ? Chip is made to work for 555cc injectors but what is wrong?

just got hold of a set of these, test fitted last night and they fitted nicely. however i was wondering what the torque settings should be on the nuts im assuming they will be the same as teh standard wheel nuts? which i also dont know what it is i just do them up tight lol. but obviously im thinking that not torquing things like this up properly can infact make a weaker join.

Ok, so I need some advice please guys. Once my rebuilt engine is completed and before I have the Emerald mapping done, what type of controller will I need to keep an eye on things and help get the best out of it? To start with I'll run a new OEM fuel pump and see how far that gets, before leaning out. Any ideas would be great etc.. welcome :balloon: Basic build info: Forged engine - Jimmer Sard 850 injectors & fuel rail.

Mangaed to get my zed in the galley for the offical site for japfest! First time its been on the track.

Took the bloke a few goes to do the centre caps done due to the corrosion, but they're finally finished. Photo's not too great i'll try and get some better ones tonight when i get it off the drive, tried a little instagram magic on the last one....

Over the weekend heading south just near J40 of the M6 in the inside lane, I overtook you in my astravan. I know not a car usually featured on here but I'm sure we had a chap, prbayantknight was it? That had a replica, wondered if by chance it was you? Looking very cool - even if I am a little young to remember the series!

Hiya, Does it matter which injector plug goes to which cylinder? I know coil plugs needs to be sorted by colours to each of the cylinders but is it same for injectors?

Well that's the Zed bought and paid for still to be picked up tho! So I went and picked up it's replacement yesterday - 10th Anniversary so only 600 came to the UK with some Bilsteins, Torsen LSD and close ratio 6 Speed :) Really happy with it and the plans are an Eaton Supercharger next year at some point! Obviously I'll still frequent these forums as the banter is 2nd to none but alas no more Nikita (My Zed's name lol ) Take it easy guys (and gals) :thumbup1: Mark

Think ive done this before but does anyone now where i can get a front seat belt extender for my 300

Ok guys n gals since Im not a TT owner then I dont have a lot of experience of looking at turbos. If I told you I had a Turbo techics hybrid turbo(Well a pair for a 300) how would you know thats wot they were?? Size/shape/ markings on castings etc.??? Do they need "special" bits of manifold?? Or do they replace stock turbos?? Do they look the same/different to stock ones. How can you tell a stock one??? Help!:confused1: :stupid:
