okay now I might have to take the idea of the trubo off my mind.. car is fully running like its on 4 cylinders of somethign the whole thing vibrates when idling and sounds like a wrx under acceleration.. guess Ill just have to see what my mechanic says tomoz :D

Update: Mechanic reckons is runnign on 5 maybe 4 cylinders.. he told me to check plugs (i've replaced them), check the fuel return to the furl tank as in might have been blocked and flooding the engine (which I've done runs fine), then he said ignition module (swapped this with my mates made no difference) next up is coil packs, and if not those maybe a blown gasket between the cylinders.. any other suggestions..

Alright I think i've discovered the problem.. I replaced the whole ignition system with that of my mates r33 so I knwo it works fine.. I then proceeded to unplug each coilpack lead one at a time.. as expected the idle changed slightly.. however when I got to the 5th cylinder and unplugged in no change.. im guess this means a problem in cylinder 5..and according to the above problems I'm think maybe a bent valve or valve spring etc.. does that sound possible??

Yes............ Or a crack through the piston ring land.

But unplugging the coil pack on that cylinder still should have made a differance. Maybe the coil pack is faulty or even the loom from the module to the coil pack. Try and swap the loom from your mate's car.

PS: Make sure you have the same series engine (ie: S1 coil packs will not work in S2 engines and vis-versa)

Have you done a compression test yet.

hey guys my turbo i think, makes a noise like this RRREEEEEEEEEE lol, under load, hi revs..

i think its standard 32 but i could be wrong, still ceramic an all..

um and 15psi gets put threw it every day..

goodnight turbo?

fan belt stretchin under load?

how long left till turbo dies?

can i screw the engine if i keep it up?

sorry to hijack...

thanks chris

Yea my turbo makes same noise u mean like a winding noise, its could be the bearings and such when i got my car serviced my mechanic which is benno from racepace called up and said that turbo makeing winding noise and could be on its way, he suggested not to do a dyno because it could blow up then and it could not said should get new one befor i do a dyno, as for how long i dont know i geuss it depends how you drive the skyline and if you use it allot.

Definately nothing in cyclinder 5 and we swapped everything between the two cars.. igntion module, loom, coilpack the lot..I pulled the plugs and plug number 5 had a build up of what looked like oil on it (keeping in mind brand new plugs were fitted yesterday) I also noticed when shining a torch through the plug hole a build up of black sludgy gunk on the top of the head (or whatever ya wanna refer to it as) in both cylinder 4 and 5.. the rest were absolutely clean (i could see bare metal)

Update: Looks like a gasket, between cylinder 4 and 5...umm water coming out the exhaust, umm cylinders missing.. and when you rev it coolant comes out the radiator cap rather than runs away from it.. if that makes sense..

eh and got the compression test shit here so will do one tomoz for confirmation a head gasket doesnt worry me as much as engine damage.. im going to europe for 2motnhs shortly and my bro is a mechanic so he ca do his work while I'm away :D

It defiantly sounds like the common symptoms of a head gasket. My mate just got himself a subaru rs wagon and he has all the same problems as what your having, exept in his case oil has forced its way down his heater hose and is now filling his floor with oil and coolent lol.

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
