Starting to part together my turbo build

Already megasquirted car, Built block, 2000 head.
Began with the RX-8 425cc injectors

How does this Exhaust manifold look? I got up with a guy who had it custom made in a shop, it is used. no cracks, dented in on the 2&3 for clearance. flanged for t25/28

Now talking compressors here.
This is going to be a conservative daily driver low boost build. just looking for more power and fun on my daily 20 minute drive on the interstate etc...

What should i be looking for? Ive seen that the GT2560 is a popular choice.

Also could use some help finding the right down pipe.
this is a bottom/low mount manifold, and right now im running a magnaflow cat back exhaust system, that the previous driver claimed to have had custom bent for fitment. and that worries me.

was there any specific reason he flattened out #2 and #3?

He said to clear the valve cover.

It looks like its never been run on a car and that the turbo might hit the frame rail. I'd be wary about buying it.

So what you're saying is that the manifold doesn't actually fit the car, right?

I think he's saying turbo hit block.

If those dents are clearance for the valve cover, I wouldn't imagine the valve cover gasket has much of a chance.

I would have to agree. That's awfully close. I guess it was mocked up on a head that didn't have a VC on it when it was built.
