Measure the OD of the 75 wheel and the ID counterbore that it fits into. You can do this on either a lathe or a mill that has a rotary table. Use the same amount of clearance (or more). Make sure you get 100% cleanup on the backplane. No step in it. If you cut too deep in the backplane, or make the counterbore too big of ID, it really doesn't hurt. But if you leave inadequate clearance (aluminum expands way more than steel), you can fk up the wheel when it gets to full RPM and temp.

Yes.

did you just have them turn it out to the same gap that is between the old wheel and groove?



yes, cover will have to be machined. i bought the wheel and cover from newly and the cover is already machined and ready to go. boy is there a big difference from a 75 to a 80 lol


im almost kinda wanting to buy a backing plate so i can sell the 75 as a complete setup for someone that wants something they can drop right in.

I was wrinkling the pavement with the loaded down 30' enclosed lolol

lol i was just thinkin about that at lunch. i still think your text from way back when was awesome.
you "uh, you towed on that tune?"
me " yeah you said it was a tow tune"
you "resend me that tune"
you "holy hell, that is NOT a tow tune!"
me "lmao, you said it was!"
you "i was kidding! we need to drop that pulse"
me "heck no! i like it way too much"

and since its been killing camaros, mustangs, hondas, and trucks of all sorts. and the occasional 350z, ford/cummins, and that "i gotta get infront of this guy hauling a trailer" vehicle.

thank you Pat. i have a good buddy with a lathe, i just dont know how id attach it as we usually use it for tubing or little things.


awesome, thank you!

Talked to a few guys on my local forum here and they pointed me towards AGP turbos here in AZ. owner will be able to shave it right down as i wait which will be perfect for me so i dont have to deal with down time.

I know this upgrade has been a pain in the dick for you. What about getting the 475 a billet wheel, port and polish the comp and turbine housings?
