Hello JC88, so that a 2.0 engine takes those horses, I will tell you how little I know, in case you want to take it: it would be complicated, but easier (relatively, if you have appropriate sewers, etc.) but atmospheric: you can only get through rpm increase, but for this it requires the increase in the entry of more mixture, also helping with a slight increase in compression, and so that RPM, (in addition to lightening masses), it will have to be shortened to change from change, (replace the conic group) and a long etc ... well, the fact is that in reality, when an engine is enhanced based on the crossroads of valves in sceso, the reality is that it becomes inconducible in the city, (at least with those 170cv in Atmospheric Just make a "repro" and 4 more things as the "commercial tuning" say, if not, I don't know what the Crisler engineers paint or any other. It limits a lot if you want to be reliable the "preparation", think about it, because to overcome those numbers that you say, there is no other than I know ... but this is just my opinion and I do not intend to discourage you, you continue investigating, there is much to know .. encouragement and luck !!!
