I do not post on here much but I have not found any other websites with a dyno graph with this turbo. This is a gtx2976r .86 a/r on a built sr20det. mods are as follows

hks cams (specs unknown came with a spare head I bought)
brian crower +1mm oversized valves
supertech dual valve springs with titanium retainers
3 angle valve job
supertech exhaust valve guides
wiseco 11:1 Pistons
eagle rods
acl main/rod/thrust bearings
ARP main/head studs
machine work done with torque plate
cosworth 1.7mm head gasket
Nistune
Isis z32 maf replacement
Tomei turbo elbow
Tanabe medallion exhaust
Id 1300 injectors
Radium top feed fuel rail
Murica Motorsports Catch can
Isis fmic kit
Isis radiator
2 12in spal fans
Isis oil cooler kit
walbro e85 compatible 485lph fuel pump

It is tuned with nistune at 18psi. unfortunately nistune and my z32 maf were hitting a limit if we tried to go higher. It still has a stock intake manifold and the only thing done to the exhaust manifold is that it was heat coated. The first image is a comparison to my s15 spec r turbo both turbos were tuned at 18 psi. The gtx2976r gained almost 100hp at the same boost. Murica Motorsports did all of the work including installation and tuning. This is a drop in turbo for the sr20det. Here is a link to the exact turbo I purchased
