Has anyone built a set of long low slope car ramps that work with a zed ? If so, do you have sketches with dimensions and material list. Thanks John

What is the benefit of hybrid turbos and what sort of extra power do they give over stock turbos. ( car also has decatted s/s exhaust). Trying to decide if its worth paying the extra for hybrids over stock turbos. Cheers. Martin.

In theory they ought to allow more pressure where it is really needed. Has anyone fitted them and found that to be right? Could you feel the difference when braking? tia

Hello folks, This has probably been covered many time before but........ If (or should that be when) I get the engine pulled to do the turbos what else should I be looking to get done? Lit of possibilities is as follows. oil feeder pipe water pump worn or perished rubber hoses that are difficult / impossible to do with the engine in. oil and filter change. The car had the belts done at 64,000 miles and has now covered 79,000 miles. Will I need to get the A/C re-charged? All the best. Martin.

Hi, Any suggestions how I can free up a siezed calliper piston? I've pumped air into it but it still won't budge :( Cheers Vijay

My end tanks have broken, the comon old problem. I obviously need to replace the radiator, Where do I get one and how much have you guys paid? Is it possible just to replace the end tanks? help would be much much appreciated.

Im trying to get de cat pipes for my 92 manual jap import N/A. Ive heard that doing this wil sustantialy increase the old BHP ! Is this the case ? Do you know any companies that sell them ? Cheers Mike

Right, I've seen all the info on clearing the front indicators with drill and/or soldering iron, but I've noticed that this is for Jap spec indicators. Does anyone know if the same process works on the stock UK indicators? (Just thought I'd ask b4 crawling about in the drive! ;) ) That's the last bit of orange on my car and it's got to go!!!

My First Zed: Silver 1990 TT, bought in early 2001 for £6000, written off in mid 2001 after bonding with a tree on a wet morning. My Second Zed: Silver 1989 N/A bought in early 2003 for £3500 (inc. £700 DVLA plate), problem with power steering that could not be diagnosed by Western power steering, Wessex Nissan or jeff at Zedworld. Sold in mid 2003 for £3500. Third Zed??? I have always loved these cars, and having been through GTOs, 944's etc, I'm considering having another go, though the model is getting older, and I'm not sure how they stand the test of time. This time, it would have to be a well maintained TT (preferably in silver!!!!). The bu…

Need to know the nut thread size, M10 or M12. I have measured them and this is what the race road say they need to order for locking nuts....

you'd need to upgrade the internals of the engine, i.e. con rods, pistons etc??

Hello there, My car (89 TT manual) shows worryingly low oil pressure when fully warm. at 3000 revs when fully warm it is indicating about 30 - 35 psi or just over 2 on the scale as my car is a jap import. I know this is far les than it should be. Any suggestions? The car runs fine and the oil level is when it should be. The turbo's are smoking badly though. Cheers. Martin.

This could prove to be a useful topic when searched for... What cars' alloys will fit ours? Eg will alloys that fit a Skyline fit straight on a 300ZX? What about other jap manufacturers? And will our wheels fit eg a 200SX or Pulsar GTiR? Or am I being oversimplistic with regards to different years etc? Cheers :) Pete

just a quick qestion, are the bulbs for the spolier brake light readily available? Looked in Halfords at the weekend and got some smililar ones that fit the holder but wouldnt fit into the glass!! If they are, where from? Cheers David

I have just put my car back together for its 1st MOT (under my ownership) and have just discovered a problem that I have inherited from the last owner. Initially the side lights and headlights were working OK. Go to main beams and the RH headlight went out. I looked further and found that the 15A fuse for the RH headlight was missing (surely without this fuse the headlight should not have worked at all). Replacing the fuse and the main beams worked....yay!! Unfortunately this then meant that the dip beams did not work!!. The previous owner obviously lost his headlights but discovered that removing the fuse fixed the problem in the short term!!! Anyone had this…

Any tips, hints or general advice gratefully received on how best to replace these. I've done the valves themselves and the rear hoses that connect to the valves but I still need to do the front ones. I'll probably not bother with the one at the very back of the engine bay. Cheers. Martin.

Hello (again) folks, If the rear turbo seals are going would this result in a decrease in oil pressure? I'm pretty sure mine is fine although the readings do tend to vary very slightly from time to time when the car is fully warmed up. My car reads 2 mmHg at 2000 revs when fully warmed up (TT manual). Is this about right? Trying not to get paranoid about oil pressure but I find myself watching the oil presure guage more than the speedo when driving ! Thanks. Martin.

Hello folks, Is it possible to inspect the rear turbo seals whilst the turbos are still fitted to the car? If they are going would you normally see evidence of oil leaks from a visual inspection from underneath the car? I should really get my zed on a set of ramps anyway and have a good look underneath. Cheers. Martin.

Here's a tweak that'll cost you nowt: http://www.ttzd.com/tech/timingtech.html

I got a couple of Autometer gauges through the post today; a boost gauge and an oil pressure gauge - both are mechanical. I was wondering if anyone had any installation tips for these? Cheerz, Dave

In case anyone wishes to replace their poor quality H3C jap bulbs with PIAA brighter bulbs, the following UK link may be of help as they stock H3C thus eliminating the soldering mod needed with H3 bulbs though little more expensive than H3. H3c's in super white and plasma only though Link

Hi all, Just to add to Macca's post, I was down @ SE today and took some pictures of the cracked suspension arms that the tension rods attach to. Very worrying so as mentioned before it's defo worth getting your car checked out if you have the poly bushings. Sorry about the picture size but I wanted to make sure that no detail was lost.

Hi All, I need to do some testing on some fuel system components but need to find 'em first! All the 'how to's' I've read are based on a US 2 seater - fuel tank and compnents are in a very different location on this. I have found something that looks like it was designed by Heath Robinson beneath the rear drivers side passenger seat (near the speaker) - seems to have a load of fuel pipes running into it so I presume this is the fuel pump control unit (?) It's covered by a big rubber 'hump'. Would I be right in thinking that I have to remove the panel (4xphilips) in the middle of the floor of the boot to get at the fuel pump harness connectors?? An…

Looks like my lump is coming out for the turbos to be rebiult, the garage are paying thank god. Looks like theyll be going to AR turbos which i picked up from an earlier thread. The garage have told me that while the lump is out i can play with it. Seems an ideal oportunity, any suggestions to what i should replace while its out and where i can source the parts from.

Any body know if it is possible and how easy it is to completally remove the AC system ???
