I have a bullseye Batmo billet s475, can't recall turbine wheel size. I will measure if someone really needs the info (it's either 83 or 87), .90ar t4. Excellent condition low mileage. My brother bought it new I purchased it from him, but I'm afraid it's a little to big and aggressive for my stock bottom ens lbz. So will trade for 466 or preferably 467.7 fmw. Turbo of trade must likewise be in great condition. Pics of turbo can be texted pm number for pics.
