I do not recommend GT35's on a 2.0YB engine when using the 2wd exhaust manifold as the turbo has a late boost threshold (usually 4500rpm) and a tendancy to surge in the 4500rpm to 6500rpm range.

However with a suitably specced tubular manifold the GT35 can work well on a 2.0YB, but certainly not what I would recommend as a road going engine.

For nice engine manners, keep with a GT30 on 2.0YB's or go for 2.2/2.3 if using a GT35.
