Compressor wheels hit housing.

So i'm in the process of changing some piping and noticed the compressor wheel has been hitting. Is this a sign the turbo is on the way out? Has the usual side to side shaft play very minimal same as in and out. Still boost's hard running 17 psi on a GCG-S1 Check the red arrow in the pic pretty sure that's not normal no idea what is...

Need a better pic with more light, but from what I can see it seems the turbo many have eaten something rather than hitting the housing?

Grab the middle nut and give it a wiggle up and down side to side and in and out if it's not contacting the housing during any of that then it's probably fine.

If it has eaten something then whatever damaged was going to occur has already happened. If the car is still driving properly and making boost the same way it did before then you probably got away with it. If there is damage to one of the blades then you might not want you go cranking heaps of boost into it.

      The MX5 has had some annoying rattles in both front doors over bumps So I installed fancy pants door bushings, which stopped all of the rattles with the windows up, but........with the windows down there was still rattles, so after some googling,  and a chat with MX5 Mania, I got some new door to glass weather seals, all the rattles, windows up, or down, are gone now Shout out to MX5 Mania, the weather seals were on sale, and when I head to Dural to pick the up they even fitted them for me for free I did see a "really" nice Blue NA sitting out front   and this Black NC PRHT that looked like it has sat in the sun for its whole life and never had a wash, the clear coat was non-existent, an it looked horrible, really horrible, but, it had a nice turbo kit with over 200kw, the thing went like a cut snake, bagging the rears through the gears and dosing like a champ 😍 But, as I've always stated, I am keeping my NC na, I'm happy with the current power the car makes In other news: MX5 Mania do a drive in drive out turbo kit, the only minor additional part recommended for boosting my car, as it sits now, is a oil cooler, and that bonnet vents are definitely required for track use Aftermarket version look a bit to "racecar" spec I wonder how Focus RS bonnet vents would look?????

      Paint is only structural when applied to the outside of Chinese and Indian cars. Otherwise it should never be present between mechanical joints that were intended to be metal to metal. Pain slips, slides, cracks, compresses, and add thickness that wasn't intended to be there. It comes firmly under the category of "just no".

      appreciated it thanks   There are threads on the adaptor. I rear re anodising but didn’t know it will reduce strength   re mating services needing to be flat/ not painted, why would that be? I am devastated as car been off for a year, fixed power steering then installed bm57 master cylinder and just before driving it this came up. So annoyed   worried and afraid to drive it, no fun caliper coming off

      And boosters can be rebuilt by the same sort of brake shops that will rebuild a brake booster.
