Well I got the bearing housing/cartridge all built up today, then realised the 18G Billet doesn't fit..........
When fitted and the shaft nut lightly tightened the wheel makes contact with the bearing housing/cartridge.
This wheel was provided by dealing direct with Kinugawa staff (not just picked off the website), as I was offered the 11-Blade or a 5+5 blade.
To me it looks like the profile of the base of the compressor wheel does not give enough clearance due to the larger 18G size of the wheel.
Billet Wheel fitted, showing contact with bearing housing/cartridge and shaft nut right on tip of shaft :
Original 16G wheel fitted, no contact and spins up fine :
Head scratching required, followed by another email to Kinugawa.
Whilst that goes through the interweb to Japan I did a bit of research (it's much more fun doing it after the event). It turns out that the bearing housing needs to be machined to accept an 18G wheel DOH !!!!!!!!.
A chat with the is now Bro-in-law required regarding his lathe and 4-jaw chuck......or if anyone on here can help
