you know? I saw a REALLY nice Starion at Buschers anual event this summer with the 4G63 in it
The set back using the original engine mounts moves the engine too far back
It may be a better choice to make the mounts then to struggle with the firewall
It reallt all depends on your budget and goals. If you can find a wideblock g63b, the stock 4g63t internals will fit and it will then bolt up to the starion trans. If you go with a 2.4, you will need to buy pistons at the least to make the bottom end turbo friendly. You also could go with a narrow block 4g63t, but your trans will not bolt up, Bill and others make adapters for other trans options...you see where this is going.
