The mailman thought he'd be nice and dropped me off a package.
They're Z1 GT600R turbos, the same turbo that came on the S14 Silvias, the GT2560R, just with the right wastegate brackets and inlet adapters to fit the Z32. I'm going to send these off to have the housings installed on new CHRAs so in the long run I get new turbos with a little mileage on the housings for cheaper than buying a brand new set. The guy I bought them from made 560rwhp on his 300ZX so with the intercoolers and piping I'm putting in at the same time, I should make a decent jump from the 325ish at the wheels I'm making now.
