What ECU should a mildly modded jap TT Auto use? and what kind of performance increase could be expected? Say with SS decat, bovs, boost controller, Blitz filter. I have seen a few copy JWT chips on Ebay for around £60 which would require resoldering the chip in the ECU, which wouldnt be too much of a problem as I have a spare ECU. Reason being one of my workmates got quoted £500 to get a chip fitted by superchips and was told to expect a 60bhp power hike :slap:?

Right guys, i've decided to get rid of my boost jets and go for a Greddy profec b spec 2 boost controller. A couple of questions though, what is boost creep and boost spike? It says in the write up that it reduces creep and spike. Also how long should it take a reasonably capable mechanic to fit it? Cheers.

Hoping for some inspiration for a freind. 300NA Auto. For some time has been quite lazy changiong up- lags and revs during shifts. Got progressively worse & now really struggles to get into 3rd. Carried out the manual diagnostic and this showed up perfect. TPS appears to work OK and hav'nt got a Conzult. Any ideas?- don't know when the oil was last changed (its done 55,000 miles- apparently)- would it do this if the filter was choked up? Any Help much appreciated! (he's so frustrated he's talking about joining the ranks of ex- owners!) :( Regards to all, Dave

Seen this one twice now, once in Jesmond and last night outside my mums house near whitley bay. Pale metallic blue with a high rear spoiler, round rear lights - very nice. I'm always in my other car when I see it. Anyone here? David

Does anyone know if there are any differences between the N/A autobox and the TT? I can't see anything in the manual but someone once said that the bell housings need to be swapped. Thanks

Think it was a G reg. Anyone here? Justin:)

Seen it round a few times, flashed lights at each other. Anyone on here ??

coming round the northern bypass - flashed you lights at me anyone here

very nice black zed, drove past u on east park road at 6.50pm, obviously not in my zed after the accident :cry: no rear spoiler, blacked out rear lights and bubble writing number plate, anyone?

G reg, near Beaumont Leys Shopping centre at 6:15pm. I think ive seen this one loads of times before but i'm never in my Z.... :( Rich

I'm hoping I can put a spacer in and get it pretty close before I take it for a check/alignment. I think Harve said that for 25 to 30mm lowered springs you will need roughly a 6mm spacer. Has anybody tested this out yet? I've got Blitz Super Traction springs and I'm not sure what drop they give. I did a search and someone mentioned they are 15mm at the front but this doesn't sound like much to me. Any ideas chappies?

Hi all, Just having a bash at replacing shocks and springs - problem is I can't get the old shocks off. The bottom bolt through the clevis is unmoveable. Is the nut on the other side a captive nut or does it need removing before the bolt can be withdrawn? It seems impossible to get a socket on it anyway... Advice mucho appreciatedo RobH(o)

Sorry to bother you big man, but you were particularly helpful when I had the 5 cylinder issues and you happened to mention something re: valves. Basically, I cleaned the connector on the injector, I didn't remove all the green but I though it would be sufficient to at least get a contact. I checked to hear for the clicking with the screwdriver trick and it was definitely A-OK. But still not firing on number 5. Anyway went up to the factors and purchased some STP injector cleaner, dumped it in the tank with a full tank of Optimax and went for about a 30 mile run - fairly hard. Came home and it was sweet as a nut, I let it idle for a bit and it never misse…

I know where this is gonna lead but I'll post it none the less for now :rolleyes: Dyno chart from a Z32 running PE1420s at 23psi - check out how it holds around peak power for a good chunk of the rev range :D This is where its at :D CheerZ, Andy

the handling on my Z is pretty awfull, not that I have had much to compair it to, (other Z's) but I feel it could be a lot firmer. It seems to drift round corners and the handling feels rerally soft if you get what I mean. How much will it cost me for new shocks, springs and anything else that may need replacing?. I am talking stock replacement.... Cheers.

Right, as per the other thread, I have contacted Mr G and he is lending me his clutch hose to have copied, as a gauge, who is interested in having one?

driver seat adjustment has stop workin...on the forwrd and backward adjustment. All the other adjusments work fine...has any one had this prob..or can any one help..... can only just reach the pedals... :confused:

seen lots of Zeds about in essex, but someones got one down my road, (few months back) in basildon...(dont wana say where exactly obviously) its white, import i think....TT not too sure anyone? :hyper: my pulsar lives down that road too, u should know who u r :cool:

Hi all I got my ZX back fromt he garage after the 72K service today. The technician didn't replace the auto-box oil as he didn't have the gearbox sump gasket. I thought UK cars had a drain plug on the auto trans, but he said there defo wasn't one..... :confused: Any thoughts? Richard :smw:

Hi all, my 1990 N/A has developed a fault where when overdrive is switched on and I am cruising along, if I lift off the gas the revs go down to an idle almost immediately, then if I accelerate again the revs build back up to normal, this doesnt happen with the overdrive off, any ideas? I have spoke to Raydetinu who had a similar fault so I am pretty sure it is electrical but anyone else know of, or experienced this that could give me some more info to work on? thanks, Richard.

Now just got to build the buggers. Will post some results when it's done, sure Leigh will too. :D

I've had excellent advice reference removing the gearbox (auto ) but im having problems getting to the top bell housing bolts :confused: Any ideas :confused: cheers :hyper:
