g'day guys,

i have a little concern about my R33. whenever my turbo comes on boost, it squeals to high heaven. nobody seems to know quite what it is. i've heard some say that its a boost leak or something from the turbo seals, but the car hasn't lost any power. am installing a boost gauge shortly, so i'll see where its boosting. got me stumped. its gradually been getting worse over the past few weeks. i dont drive my car particularly hard, but i kinda have a feeling its time for a new turbo. any ideas would be great.

cheers.

ok, so installed to boost gauge on the weekend to see if its leaking, and its not. its running at spot on 7psi. doesnt roll back, it just sits a dead on 7psi. so, i took off the bov to check it all out. the gasket is a thin metal one, so im thinking of changing that. but its not leaking any boost, so this is leading me to believe that it may be an exhaust bolt or something else. am yet to check the turbo, but will try to do it soon. work is flat out atm. hhhmmmmmmm.....dont know what else to do.

      IMG_8641.mov     She doesn’t sound the best but starts with out using any gas now. I just ran some injector cleaner through her. started roughly the first time after adding it but gave it the beans slowly upto 4k, Must have cleaned a few cobwebs out. another step in the right direction for the sub

      Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in

      Let's just fix the problem by f**king the rest of the gearbox.

      Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
