Had my car on the Dyno today, best run was 407bhp but it started climbing out the rollers so they had to stop as it was affecting the readings. The car had a misfire at higher revs too apparently, as it went on the rolling road it certainly wasn't running on all 6 then seemed to clear. I took a video and I would appreciate it if anyone can advise me on the smoke, what it could be and how to sort it, thankz :) [YOUTUBE][/YOUTUBE] [YOUTUBE] [/YOUTUBE]

thought this would be an appropriate place to post this, gatebil is swedish i think and they have some awesome and insane motors, even old 240 volvos with massive bhp this is my fave so far and i would to own an audi s2, was in one years ago and they are amazingly quick and handle great enjoy [YOUTUBE]73kALf6IMvM[/YOUTUBE]

Anyone who is running their Zed on 19" rims, what profile tyre are you using on them?

Been working today on getting the car prepared to have the floor pan and sills welded. Spent the morning taking out the seats and carpet to reveal the extent of the rot. Then spent an hour with a hot air gun removing the sound deadening and managed to only burn myself a bit once, which is pretty good going for me ! Other than the rust you can see, there was not much else lurking underneath, which is good new. Is it possible to get replacement floor pan panels ? If so does anyone know where I can get one quickly ?

Anyone in/near Croydon with Conzult? I have a long running smoking problem on hard accel. Seems like over fuelling to me but want to run a diagnostic and rule out potential issues. I've never used Conzult before and don't have it so hoping someone on here can help out... Thanks Vig

So I've ended up buying 2. One is genuine from a forum member and the other is from a company called import car parts and is advertised as OE Quality. So I'm curious what the differences are if anyone knows and what's the best of the 2. Here are some pictures, the Nissan one is on the right:

Hey Have just completed a compression test. These were the results. Bottom Left - 160 Middle left - 150 Top Left - 140 Bottom right - 70 Middle right - 70 Top right - 50 Dosent look good to me!! What results should I be seeing. Any ideas on likely problems with readings like that? Cheers, Nick

My understanding is: Low beam H3c (Jap Spec) Main Beam H1 (All Spec) Why does my car look like H4 in the Main Beam? My Car: (Jap Import)

after indstslling headers and a afpr at the weekend i took my zed out last night, and its developed a misfire/ hesitaion at 4K+ rpm, on throttle, if i back off the throttle a bit it stops and revs fine, i've got to drive it to noel for mapping at the weekend, i dont want to drive too far if its not running right. its a 95'NA, also over the weekend had a carbon canister delete, and duel intakes fitted, (did a test run before chaning headers was fine) base fuel pressure ( which i hope i've stright) is 3.1 kgcm2 with engine running and vacuume disconected, (43psi) one of the 02 sensors is looking a bit slugish, but is working and changin corectly …

ive just had word back from zedworld that my Z went through the MOT with no issues . big thanks to jeff for organising the test and taking care of the car . thats four years running now 1st time passes . to say im happy is an understatement . mind you shes only done about 20 miles since last years test so i wasnt expecting too much to have wore out.

Don`t get some peoples idea of removing and supplying an engine, currently fitting an engine for a customer who bought it not seen. The customer removed the plenum for powder coating and dropped the rest with us for build up cam belt service etc etc and fit into his zed. But why remove the engine by cutting the wiring loom to the alternator, cut the oil cooler rubber pipes, hack the ac pipes, cut the cable to the oil pressure sender etc. So making the job harder by cutting stuff is just bonkers, next to no time saving when removing from the donor zed, just unprofessional and lazy in my view!

Japspeed Steering arms has any one used them as need to replace one side as my inner ball joint has play seen some of the generic ones for 30quid .. each but the japspeed ones are 80 pair anyone use ?

i'm looking to buy a quality set of suspension without paying over the top, ive got eibach adjustable all round at the moment but they have aged and i'm not to keen on them anyway, although they are great for handling and lowering the car i just feel like i'm driving about in a bobsleigh as i feel every bump and with me planning on doing alot of miles i just dont think they are going to be suitable, i have no intention of paying for the name and have seen a couple of sets on the bay from bc, racing logic, daiyama and slide and also seen the meister set available on the forum has anyone got any recommendations from experience please

I'll change the question since I didn't get any respone in my last post :( Has anyone heard of any other Z owner that have had problems with running without diff and transmission cooler ?

I am now looking at how much to insure when I finally pull my finger out and get my Z back on the road.... Let alone taxing it.. and the MOT.... Does anyone know if the emissions come into play with a 1991 Z...? I threw away the cats and went straight through 3 inch pipework.... I got a quote for agreed value (needs a written valuation done), fully comp, Garaged, 5000 miles limit, £250 excess, £75 glass excess, All mods declared, includes legal and breakdown recovery and buy back in case of write off...... Was quoted by LynBrook £269.69..... Is that a competitive price?? Haven't used my car for 6 years and last paid about £850 fully comp.....:w00t: Ch…

Hi all. I keep reading about people having boost creep problems with bigger turbos at high boost and rpm using the 3" down pipes. Has anyone come across this problem? I hear the solution is to remove the divider in the down pipes. Cheers dan

Groover, These would go great in your engine. http://www.ebay.co.uk/itm/171041745278?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Never really seen them before but they claim to be close to the splitfires (performance wise).

So, I'm having a daft half hour so I thought I would post up and hopefully be considered for the post of the year which I believe will be awarded at JAE. So, I've decided, Artztogo (Chris) is really Mick Fleetwood (from Fleetwood Mac) So here's Chris winning a well deserved award at JAE 2012... I can then imagine this being Chris, on some talk show discussing his big win... And then on the red carpet and posing for pictures... And his old sound system -vs- the new sound system, he prefers blue over purple now :) OLD NEW (he doesn't even need to stand before and pretend he's playing this one. And finally, s…
