hey guys..... there is this dam noise that has only started about a day or so ago... i was driving home at night... and noticed that the car when it hits full boost (1 bar) a wistling, screeching kind of noise is comin from the turbo area... it is most noticable when u boot it in 2nd...and gets less and less as the gears go by... i checked for leaks and so forth.... and had a look in the front of the turbine to see if the props are all tight and everything seems fine... its a really weird noise... and i am sure its either the turbo or the external gate.... but stumped/... its a r33 with a t04e garret turbo high mounted..with all the bolt on mods.... any help would be appreciated... but this sound has me sketching!!!!!... thanks guys

anyone with n e ideas what so ever.... ??... all bolts are tight...external astegate is tightened up and all... the only thing that looks wrong is an oil leak from the side of the engine (its tiny tiny tiny) and i dont think that would have n e thin to do weith it.... cause its been there for alot longer than the noise...

sounds like its an air leak. could be gaskets. Also try checking all the silicon hose joiners are tight. u say the exhaust gasket has been recently replaced, the mechanic could have been lazy and not tightened everything up

      Sane enough. Remove the roof liner, because the acid will go everywhere.

      Rusty roof repair

      By PranK 路 Posted

      Thanks guys, I really appreciate the help and experienced opinions.  I have spent a lot of my life working on boats so I'm pretty good with fibreglass. I'll take everybody's advice in here;  I'll cut a little more of the 2nd layer away as it's a bit crunchy rust and also it's sitting high now. Then I'll wire brush it all a bit to get off anything loose, then I'll soak the bejesus out of it all in rust converter. I'll make sure to get a little hose piece and feed it into all the holes and gaps between the roof layers. Then I'll fibreglass up the holes.  Then I'll get a pallet of filler and mix it with 3 buckets of hardener and hope that is enough to build up the roof corner.  Does that sound sane? Is one type of filler better than others for this?

      My goals for it atm are to get it registered, respray and some mild power gains eventually... I picked up the car from an elderly gentleman near the border of NSW and VIC, its honestly a bit rough and looks like its been driven on a farm (because there was so much dirt underneath). Last week I dropped the subframe and emptied the old fuel out + added a new fuel pump (think the old one went bad from old fuel). Now I'm onto fixing a coolant leak at the rear of the engine + adding a new radiator as the old one is corroded. After that i have a new bumper, coils (as the old were leaking) and lots more

      Love this so much! Please post a photo when you have a bike on the trailer.  I was a little bit worried about having a tow bar on the Skyline, but having it hidden behind the number plate is genius
