It's a 2.5 built cosworth long block with big port and big valve heads. Awesome cams. Water meth and GT35r size turbo. Hydra stand alone computer. Larger front mount. And the best thing in my opinion is the Cosworth intake manifold. Also got a AMR unequal length header and up pipe. Getting all new gauges. Twin disc clutch. New tial bov and ewg. Should be all set for a while. Goin to the body shop as soon as its tuned......
