Just thought i'd start a topic to make sure you all know that Rossmod can do the crankcase mod required for any V4/X4 or evo3/2/1 MCD models.
I think this is a great idea if you're purchasing a new engine from them and would prefer to get the mod done before delivery. Just remember the crankcasing is only 2.5mm thick, so if you're not confident to do it yourself, get Rossmod to do it... don't want to cut too deep and stuff a brand new engine.
Looks like they do a pretty neat job of it too
