Help me size a new turbo for new setup: high comp z6 EF
I want more power. I had a feeling it would come to this right after I finished the car, and it did.
I have a built z6 with eagle rods and srp 10:1 forged pistons skirt coated
Head is z6 with a pretty big port/polish job, oversized ss valves, 59300 cam and OEM springs for now.
IM is stock z6 portmatched to the head
Running RC 1000cc injectors (overkill, but I got a good deal on them)
Factory ignition
Chipped ECU on Crome, probably will be changing to ectune though
I don't have any numbers, but according to butt dyno and beign told what the turbo is capable of, I'm guessing somewhere around 180whp. I want another 100 if at all possible. Ideally I'd like to see 300 but it isn't a sleeved block and I'm not so sure what the D series is going to be able to take on a car that is basically a backup daily.
Goals: rolling burnout capabilities, good acceleration in 3rd and 4th. Right now it's a dog in any gear above 2nd, and doesn't even break loose in 2nd.
Current Turbo is the Greddy TD04H on the greddy D series kit cast manifold, but with custom 3"DP. I want to replace the manifold with an external wastegate piece, but may be making my own. More than likely I'm going to have some sort of mini ram type manifold.
I have a small 12x3x6 FMIC and want to keep it that way if I can, but intake temps are high with the lil bitty turbo.
Any suggestions?

Flange: T25 but that can be changed as the manifold will be changed and I will have to redo the downpipe.
Manifold: Undecided, but leaning towards a mini ram
Budget: Not really an issue, but within reason. I wouldn't spend more than $1500 on a turbo and a manifold. I have everything else.
Oil/water cooled: Again, not an issue, whatever turbo will be ideal for my setup is whatever system I will have to deal with.
Basically I have no idea how to read compressor maps etc to figure out the ideal turbo for my application, which is fairly specific. The one I have on there is way too small. It's fine at 7psi but beyond that it definitely feels like it's struggling, plus my intake temps are extremely high.
