So I finally got fed up with my engine. NOT because it has no power, like seriously it was fun having to drive around town and not worrying about fuel in this little engine. But its been costing me unnecessary expenses. So I've made up my mind to disregard the small cc and op for something worthwhile. I plan to go with a 4g91, but then I heard people saying 1.3 chassis can go for 1.6 engine. That being the case, if lady luck is at my side, might as well go on a treasure hunt for a 4G92 mivec. But the question is, what basic stuff should I look for when purchasing this 1.6 monster, and what should I do before I put it in the car (overhaul, etc). Mod ideas also welcome 

.
Side note: Can anyone tell me, if it is possible to get a 4g91 block and fit it with a 92 mivec head? Or will it have troubles in terms of tuning and stuff?
