camgti 56 Posted September 19, 2008 Now that im in a position to actualy get moving on my build, ive found (quite rare over here) an RGX 2.0 Turbo. It has 157 000 Kms on it and the compression the guy is telling me is 155 psi on all 4 pots. Does this sound correct? Im planning on Fitting a Garrett GT25/30 onto a custom manifold running a haltech and a few other bits. After about 230+ HP not any more really from about 14psi. Any thoughts?
