About 3 weeks ago I did a boost leak test and fixed various leaks which i fixed , to get to one of the leaks I had to remove the TPS. Put it all back together and adjusted the TPS to 0.45 , now the problem I have is that the TPS voltage keeps moving up to 0.5 so I adjust it back to 0.45 , this has happened 4 times now and I physically do not have any more movement on the adjuster on the TPS. The TPS is only 6 months old and the car has only done 2k since i fitted it. Before I took it off and fixed the boost leaks it was rock steady at 0.45 all the time. Anybody know why the voltage would move without adjusting the TPS itself ??? Ryan

I'm going to buy a set of front upper arms because 1 of mine is in bad condition and car is not stable when i hit the brakes moreover it's tearing my tires from the inside.I thinking of buying the tbo anyone got them are they good or you suggest another brand?

Does anyone have a photo of the gear knobs Luke sells,the after market brushed chrome with badge on top????

After 2 years I have finally got a full rebuild of my TT SWB auto Box Its finally selecting all gears but I still have problems When flooring it goes to redline in whatever gear it is in but refuses to drop to next gear. to drop I have to take my foot off the accelerator monenterily and it drops OK. The guy who did the box said my TPS isnt set up correctly so went home and tested it. I seem to be getting ridiculous values of about 8V when with throttle closed and oscilating between 9 to 13 on open throttle. I am reading between middle pin and ground. Does it sound Like I need a new TPS, does it prevent shifting under full throttle or is there more work…

Is there an ECU diagnostic code for det sensor failure? cos all I'm getting is code 55

to cut it short Jap tt 91 auto, new NGK uk plugs in her (PFR 11C). do i have to gap them myself? OR do you leave them alone? If so what should they be?? thank you JIM.

The actual rad is fine but started leaking from the top hose yesterday. So i unscrewed the jubilee clip from the top hose and pulled it off the rad and the bits of broken plastic from the rad inlet fell to bits! Maybe previous over tightened the jubilee clip, dunno. But i guess i need a whole new rad , so does anyone know the best place to get one? Thanks, Trev.

evening all, just wondering whats best. I have had my jap 91 tt auto for about 9 months now and been slowley changing all the service bits (43,000) ie autobox fluid, fuel filter, air filter, tps, pipes, etc the list goes on and on. I have now got a code 34 (det sensor)? Its always been ok on super unleaded with the jap plugs in, but i changed to the uk ones anyway. without condeming the det sensor, is there anything i can try? the car feels awfull when in saftey boost (real heavy and no edge) thanks for any help?? JIM.:( :(

Having seen the current prices of Zeds online and in autotrader i'm wondering whether it's better for me finacially to break my Zed or sell it. It requires the oil pump replacing due to it's casting being damaged by a garage trying to prise off the pulley. It also requires a full set of locks. (No key for the drivers door.) It has a little bit of the obligatory bubbling under the rear spoiler. It is a 1990 black import twinturbo, with 45000 miles on the clock. I rebuilt the engine fully after it popped a head gasket two years ago. (used the original turbos.) It has a super megaphone exhaust and a HKS intake. Oh, not a spot of rust either! I converte…

After been told by my local nissan dealer that the autobox sump gaskets are back ordered (from overseas) and will take 5 weeks to arrive (mine been an import has no drain plug) I was wondering if anyone has ever sucked the fluid out through the dipstick tube ? Thanks John

In the glovebox or anywhere else ? does it fit anywhere nicely ? Cheers

Fitted my JWT dual POP on Saturday, bit of a tight squeeze but not too bad, however I did have a couple of issues...... 1. After removing my AFM from the T piece, I discovered the mesh on the back was in bits and had most probably been shooting metal filaments at my turbo's for at least a couple of thousand miles...... 2. Upon fitting the 555/dual pop chip my car now detts at about 8psi...........needless to say I'm somewhat unimpressed by this - any suggestions??:confused:

Hi all Continuing fast idle problem. (uk TT auto) After previous post, (cleaned TB's 3-4 weeks/1500 miles ago) and idle has been around 1000rpm since. I acted on the advice last given and cleaned the idle control valve thingy today. I reset the ECU (disconnected battery for 1.25 hours. I initially removed the two plugs from ECU but as engine still started, I didn't know if they were the right ones so played safe with battery disconnection too). I also cleaned the TPS connectors while waiting for good measure. Anyway when all done, I started the car and let it warm up. Woohoo, approx 700rpm idle:) I went for a drive of 3 miles or so and when I got h…

I know this is slightly anorakey but I want to change the piping under the hood. Can anyone tell me what the internal diameter for the vacuum hosing and petrol piping is. I thing the vacuum pipes are 4mm but not sure due to wear and tear. Not sure what the petrol pipes are at all. I think it's time for a bit of braiding and silicon!!!:D :D :D

Hi Guys just wondering if anybody has had a Zed superchipped - They can chip your car for around £500 with a claimed increase of 70Bhp. Just wondered if it is worth it or playing safe and go the route of a SE / JWT chip and a boost controller... Oh and one more thing what sorts of gains would I be seeing on a UK zed - I reckon 350ish with an induction kit & exhaust?

Hi Guys, Need to know of an upholster to patch the leather bolster on the drivers seat... Anyone got phone numbers/prices?? post your contacts here... Cheers Ben
