since last night I bad rattling noise as emerged from engine bay...Its definiately not the dash.

I find I can make the sound worse if, I put into gear (i.e. first gear) and release the clutch to the point of friction where it lets go, without putting pressure on the accelerator pedal..

ANy ideas? This is worrying me....

Na it will be ten VVT my friend. My S14a does it and nearly every S14 i know and some S15s that have a few more K's(not Many though) do it. Common problem. Cost around 1500 to fix, not really worth doing as it doesnt really cause any problem. If the car is still under warrenty get it fixed, he he.

its hard to varify what the noise is exactly without hearing the noise coz some noises sound quite similar, but u say u can make it worse when selecting a gear but the noise goes away when u engage the clutch abit in gear? Possibly an internal gearbox drama, mainshaft bearing/s, counter shaft bearing/s something like that, but again unless i know whats actually happening and when, with what noises etc its hard to tell u, ur best bet is to talk to someone in person(ie a mechanic or gearbox place) and see what they say. U could try talking to boosteds15 of www.boostcruising.com he has an s15 which has had afew gearboxes replaced. maybe u have the same drama

my s15 has done 28000kms. and it doesnt happen when i rev the car or while normal driving.

i agree sweetr33 sounds a gearbox problem....ICE in melb says its possibly the thrust bearing. Pain the in arse to change cos u gotta take out the whole gearbox....

I can make the noise appear by putting into 1st gear, then slowly disengage the clutch to the point of friction where I nearly stall. By the way this is when NOT pressing the throttle.

could it also be the engine/gearbox mount?

I know i might be repeating the people above but it really sounds like a thrust bearing issue had a similar problem on an import gemini, turned out the spring that holds the bearing had come off and lodged itself between the fork and bearing, thus always making it touch the pressure plate.

Mind you my problem ended with a screech squeel yelp and than bang as the pressure plate disintigrated the thrust bearing, in amongst other things.

Pull of the g/box and check it and its not that much of a bitch if you gotta pit/hoist.

there is 6 bolts holding the box on the bellhousing 4 holding the tail shaft 4 bolts mounting the box disconect the slave cyilinder and yank out the shifter.

Ohhhh and don't forget to drain the oil.

ooo and trhe starter motor 2 bolts holding that one

Hope it helps

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
