I believe it is. I know on the new 06 Civic SI kits that the only turbo upgrade option they have is a GT28

Yes, T25 inlet and discharge. GT28RS, GT2871R, GT3071R-WG are some of your options that fit the greddy manifold and downpipe. Or you can go custom and get a T25 inlet and a 5bolt garret housing in any trim you want.. but you need a new custom upper downpipe.

dont mean to thread jack, but how does the t3/t4 compair to the greaddy kit stock turbine?

Basically the difference between a Garrett T25 and a T3/T4 is the size of the turbine wheel. This difference in wheel size necessitates a bigger housing...
