Have you done a build like this before? If you are unfamiliar with Zs, I would suggest buying a running and driving stock or near stock Z, not an unfinished project with a bunch of aftermarket parts. This is one of those things where you really need to be familiar with how they go together. And who knows how many pieces are missing from the project, and how much it'll cost to repurchase all of them one at a time.
The shell looks pretty good, some of the parts are decent. Seems like he spent a lot of money on wheels and flares. Looks like probably a stock L28ET in unknown condition, and a set of coilovers from a brand I've never heard of. CX Racing as far as I know is chinese stuff, not sure if it's any good or not, and he lists the turbo as a BW T4 with a value of 600 which makes me think it might be some old journal bearing turbo. He has quite a bit of stuff from Skillard, which I'm not really a fan of, from what I've seen it's mostly sheet metal parts that are only suitable for a race car. The brakes are nothing special. Kinda comes down to personal taste as to whether or not you like the build he's doing. Personally, I'd be building it a lot differently.
