While inspecting my intake hoses for a different problem, I checked the turbo and it has heaps of forward-back play in it. Similar to this YT vid, maybe a bit less than this:

I am not concerned with lack of power, but will it be safe to drive this on stock boost for a few months, until I can afford to get a hiflow? It spins smoothly by hand.

Thanks

You can have shaft play with a BB setup. There is shaft play on EVERY turbo. There is just less on ball bearing than journal, once the oil is in there of course that disappears.

A turbo that doesnt have any movement would be siezed.

All my Ball Bearing turbo's have had minor play, they were all brand new.

That turbo though = fubar. So if your anything near that then don't even waste your time.

Honestly you are better off just buying another 2nd hand one, $350-$400. Rebuild will be more than that, hi-flow for a decent Ball Bearing jobbie is $1700 :)

Save yourself alot of time and buy a new turbo,do not put that back on,unless you want to pull all the parts off your engine and search for all the bits when it goes. (past experience) even found a piece in my Idle Control Regulator.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
