14B turbine shaft nut?

[Sjd6795]

I was fooling around with my turbo yesterday swapping a 18g into my 14b housing but without porting the exhaust turbine is way to big so I will just use my exhaust turbine from the 14b inside with the 18g. However I can't seem to find the shaft nut I found this one and I think it may be it, but I'm not 100% sure it does screw on but it feels the threads are either dirty or a little different.

Here's a picture of my nuts

Not sure why my flash didn't work as good on this one.

That's a right-hand threaded compressor nut from an old 14B turbine, sure. Hex size is 11mm or 7/16"...the flush "hex" side faces out; the "circular" side faces the wheel. 90% of weekenders install the nut incorrectly.

The 18G you're referring to must be an old TD06SL2 model from FP, hence the reason the turbine wheel is too big. Any other 18G's produced for our cars (MHI/Greddy, older FP turbos) all had TD05H turbines...the same as a 14B.

Thanks for the piece of mind already had the 14b come apart once while at 17 psi. Luckily no damage was done 200,000 mile turbo with aboslutely no play in it at all just needs new seals because it's leaking oil. I posted the inducer size in the turbo identification thread its 1.98"
