| The turbos are Garrett GT2560R's which were previously known, and often still referred to, as GT28R's. "GT600R" is just Z1's name for their package deal. JWT 530BB's are GT2554R's with modified compressor inlet and outlet flanges to fit the Z's piping. GT2554R and GT2560R both use 5-bolt downpipes.
