Was speaking to a guy today who said that he used to do alot of work on turbos about 10-15 years ago.

He told me that he made a device that would keep oil flowing through the turbo for about a minute after the engine was shut off... cant remember exactly how he explained it but basicly he had a seperate cannister with a small amount of oil in it, which when the engine was shut off, a valve would open and allow this cold oil to flow through...

anyone heard of anything like this? or is this dude talkin crap?

It could be done, but just wondering if it would help much since when the engine is on the turbo is spinning at a specific rate and while the engine is on all the oil is flowing through the bearings etc while they are moving etc, i dont think letting oil pass through the turbo while its not spinning would be so effective. I myself dont use a turbo timer just for the fact that 5-10min before i enter my driveway i take it easy and let things cool down, and then give it 20 sec to get out of the car etc then shut it off. My 2 Cents.

This sounds similar to a system that Subaru use in the B4 engines to cool the turbo down properly.

Just use a turbo timer and make sure it's wired to the handbrake so when the handbrake is disengaged it'll shut the car off immediately

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
