Selling a Garrett turbo from an SR20 with minimal shaft play, a 360 degree thrust bearing rebuild kit, two wastegate actuators, and an ATP turbo actuator bracket for clocking.
I picked up the turbo from a 240 friend who said it was in good condition, I bought the rebuild kit just for peace of mind, and bought the actuator bracket because the turbo needed to be clocked and the stock actuator position wouldn't work. Before I started rebuilding it, another friend of mine decided to sell his GT2560r so I decided to jump on that. I'm just trying to get back what I've paid and get this out of my garage. Also comes with a bag of miscellaneous turbo hardware I've acquired.
One wastegate actuator is the stock SR20 actuator, the other is an adjustable no-name actuator I ran on a Chinacharger at 12 psi for about a year with no problems.
Looking for $250 plus shipping for everything. I want to sell it all together. If you have any questions or want more pictures feel free to ask here or PM me.
Everything I have found (see below, copied from this thread, post 9: https://www.miataturbo.net/diy-turbo...o-specs-31779/) says that the SR20 turbos have a compressor A/R of 0.60 and not 0.80. Are you sure this is the stock SR20 turbo? I may be interested but I would like to figure out how good of a fit this would be for my car first.
Also, could you post some pictures of the turbine that shows its A/R marking?

There is a bunch of info about the Nissan M-24 turbo if you give it a quick Google, I know that one post you quoted didn't address it and I'm not sure why, all I know is it came off a SR20. The coating on the turbine housing is either ceramic or just paint, not sure which. It's coming off in some sections but it's pretty stout. Looks better than a rusty turbine housing if you ask me, haha.
Thanks again,

Does anyone know how this will perform vs the standard 0.64 A/R turbo that a lot of people on this site run?
Thanks for the pictures! Is that just paint on the turbine housing?
