So....down the road...if and when i ever need to re-build my engine...I would rather buy a new 1.8 ltr engine to replace it with. Would I be able to do that and if so 1. would there be other things i would have to replace besides the engine and if so, what? 2. are there any specific 1.8 ltr engines that would be the best choice for this? I love my xb and i don't see anything out there i would want (including the new version xb) but it would be nice to have a bit more oomph. I've done some mods and i'm happy with it for now but if at some point I have to go through the trouble and expense of rebuilding the engine anyway, I would consider this an opportunity to do something like this.
