Message these are the differences:

1. The Greddy TD05 kit already comes with Greddy tubular manifolds.
2. The Greddy kit uses Greddy Type-S external wastegates. vs. the much more expensive HKS racing external wastegates used by Pentroof.
3. The Greddy kit comes with downpipes and intake piping.
4. The Pentroof supplied TD05 turbos come with a much smaller turbine housing (6cm^2 vs. 8cm^2 of the Greddy kit) for faster spoolup.

As for using Pentroof manifolds with GT2530, compare the 160+cfm the Pentroof manifolds flow at about 8-10mm lift, vs. 100cfm for stock manifolds or even 110cfm for extrude honed manifolds. Given the GT2530 do benefit from higher lift cams, they certainly flow enough to benefit from Pentroof manifolds.

It should be a little easier to plumb the GT2530 with Pentroof manifolds, because there is no external wastegate piping to worry about.
