I have started to research rebuild options for a project that I want to take on later this year. I currently have a fairly clean bone stock fuel injected 1.8 engine with 50,00 miles.
I want to build an engine that puts out around 120-30 hp and has good middle to top end power. I mostly do AX and an occasional track run. I'm not terribly concerned about classifications etc. I just want an engine that keeps me out of the way of faster cars during track days and can put me into the running for top ten times in autocrosses
It seems to be that most think I should buy a 2.0 engine and build a 2056. Are there options with my 1.8 case and heads? What are disadvantages of using a 1.8 and increasing displacement?
