jap ae86 bigport cost me about $1500 all up including 1000 for motor package including extractors ecu loom inlet alternator etc then the rest went on exhaust and fuel pump and lines and filters etc
98kw, 100kw and 86kw are just ways of identifying the engines. They are the factory rated power that the engine came with (some people say they are overestimated but I don't know). Also an engine that is 20 years old is likely not to be putting out the same power as it was from the factory anyway.
If I were to do it again I would go a 100kw because they are slightly more torquey and most will have lower kays and they are still cost effective and easy to upgrade...
