When i'm driving along the road and floor it a bit i get a strange noise from under the front of the car Its sounds like a deep tone rising slightly before it disappears Could it be a boost leak or a slipping autobox.Ive got an fmic,chipped ecu, boost jets it only started making the noise after i fitted all this Oh and the turbo's whistle now anyone got any ideas:confused: Jim

Hi all Does anyone know what the flow rate is on standard TT injectors? I know 500cc are an upgrade and are good for 500 - 600BHP but i have seen skyline 440cc injectors for £80 and want to know if the standard TT ones are 440cc or are they less?

Yes its official I have a 'squeeky clutch'. When I depress the pedal it squeeks from underneath car. Popped into Mr Clutch and was told I needed a new one. Labour alone was £260. I have no gear changing issues, no slip, no tight pedal!! Is there an easy lube solution chaps.

Now some things you do see on a regular basis, Pic 1 below a broken fan shroud, nothing unusual about that but look at the second photo to see the cause of it.... the water pump shaft has snapped!! allowing the fan blade and viscous to fly off destroying the shroud and just marking the radiator ( lucky )now you don't see that very often. Will update on when it is fixed and what caused it, I do have a theory already:( anyone want a guess? Jeff TT

here are some pics that you wanted mate - theyre 19/275 at the rear. the Eibachs should drop the rear 20mm. hope theyre useful. :)

Just since the weather has got warmer i can hear my vicous fan more than before, its definatley not the sub fan, but the viscous. When accelerating hard, i can clearly hear it, have checked all the pipes, and heating side and all is good, its not losing water, and the temp is a good as gold. Its driving as quick as it has ever done Why can i hear it so much more, is it as simple due to the ambient weather being warm, as in winter it dosent do it........ Lots of questions i know,

Help... My bmw is driving really rough to a degree where i couldnt drive it this morning. Over last few days it's been getting worse and worse. When you accelerate the car doesn't go, it shakes like it's peaking. The revs take ages to build up and hardly move. I'm going to take a look shortly, what can I try? I'm going to check the plugs, leads, blockages in the air intake, fuses. Any loose pips in engine bay. Anything else? Any ideas??

Being its 20th birthday I thought I'd treat it to 'a few' things: Powertrix front and rear upper arms, and front tension rod KYB AGX schocks and Eibach springs all round Wilwood front brake conversion with 330mm discs Oh, and a brand new bodykit :dance: dont pay any attention to the 18s up front - the matching 19s will be going on once Jeff has fitted the new suspension to replace the [fooked] stock suspension. ...bit better than a cake and a pair of socks, i just hope she appreciates it!!!

Sorry for so many threads at the moment about my engine rebuild but first time ive done this so learning curve. As the headgaskets have failed on my engine i was going to get the heads skimmed but how do i know which size replacement gasket to order? or do i have to wait for the machinest to tell me the size?? Andy

Hi guys/girls, Got about 650 quid to spend on some rims but not sure what to go for. Seen a few sets on E-Bay from a seller called DP-Motorsport. I want 18" minimum and ideally want a deep dish design but I'm open to suggestions. Any ideas would be greatly received. Many thanks, Rob

Found a leak from the radiator which i thought was where the coolant was going down from, filled the car with water to get me home from work, just started her up and theres more water coming out the exhausts. looks like me headgaskets have gone lol really glad im doing an engine rebuild now. just hope the heads are ok and havent damaged them. Andy

Saw you this morning, blew my horn as i drove past in my lorry, very clean car you have.;)

Just got the car in the air to do the water leak (rad p*ssing out at bottom) but while checking the underneath i found a plug disconnected on the same split loom as the steering rack motor? does anyone know what its for?

Just got a rough guide of all my parts for the rebuild, will be looking around about £6000! think ive gone over kill at the moment saying ive only was looking to spend £2000 lol started out being a minor rebuild, pistons and recon the turbos keeping standard injectors etc. then i got carried away building a monster lol large turbos, upgraded cams, injectors, etc etc lol. might go back to orignal plan for time being lol.

Inside out feature As per the title, if there any parts ( not internal engine parts ) that I can dis-assemble and photo with a working explaination let me know here and will do my stuff. Jeff TT

Inside out feature Cas unit The cas unit is a much talked about part of the zed engine but quite what it does and how it does it is more of a mystery for many than its needs to be. It`s closest comparison is the more commonly recognised distributor on engines in the past, but the cas unit does a whole lot more than the lowly distributor. The ecu takes signal pulses from the cas unit pick up, these signals are used to trigger the coil pack at the correct time (ignition timing ) and to feed earth triggers to the injectors again at the correct time ( fuel timing) To know how it does this take a look at the photo's, the reluctor disc has a series of…

Hi people, looking at rebuilding the engine soon and decided on nearly all areas of the rebuild except for what turbos to have! want an overall turbo fast at spooling and good at high revs but dont want to spend loads on these. Im a best in getting the original ones upgraded? and when the engine is complete with the rebuild what type of boost is save to run at? also will i need to take it to a rolling road/performance garage for them to set up the mapping/timing/best boost etc etc? Thanks again Andy

Is it that you fix your Z and then find even more wrong? LOL Finished fitting my brakes and just need them bleeding tomorrow. Put my rear wheel back on and noticed a screw through an almost new 295 tyre! :rolleyes: :cry: Tyre hasn't moved in a year so it's been there ages and hasn't gone down. I started to unscrew it hoping it might be a small one but noooo it started to hiss and the thing is about 2 inches long. God knows how it got stuck in there. It never ends!

Ok my electric fan packed up earlier, the first time it was the fan controller so i had my mechanic wire it up so its on full time.When i finished work i went on a nice little drive to the pub and noticed the temperature getting a bit higher than average and i didnt think much of it as its been very hot today! so on the way back it started to to get to 90 degrees give or take a few so i pulled over and turned her off getting a bit worried and then put the ignition on and i cant hear no fan? popped the bonnet only to see coolant bubbling outa the pipes! (started panicking by now) let her cool down a few hours before picking her back up and limping her home...Anyway i have …

I've been thinking about a silver on black rear number plate for my Z as I think it might look better on a white car. The DVLA website says they are ok on pre-1973 (I think) but there are plenty of much newer cars round here wearing them. Any thoughts guys on legality and style choice ? Mark

Hi everyone Looking for a big favour from a member. Got a missfire that comes and goes on my 300tt and error 21 (PTU). Read through other threads and most suggest "borrowing" working parts from a running 300, ie coil packs ptu etc... to isolate the problem. Willing to drive to your location. Any takers ????

Managed to get a quick trip to the dyno today to sort some running in mapping but unfortunately my clutch release bearing siezed on one of the run downs so had to cut the session short. Didn't even get any mapping done, just enough runs to establish 2 things really: First that the fuelling is still too rich but OK to run for now. Second that the airbox/intake hose combo I have is too restrictive. Didn't manage to isolate which part due to the problem above, very frustrating. Results so far, with air box lid on, ~350bhp. With lid off 420bhp @ 7.5k (on the current rev limit). Not too bad for such a rough, guesstimate tune, hopefully a bit more to come. I think I …

Spotted a Red Series 1 LWB TT (not too sure on the gearbox, was in the bus!) in Clondalkin, Dublin around about 13:30 this afternoon. Was it anyone on here? Very tidy looking example apart from the paint flaking off the spoiler.
