I own a 1982 Coupe, and have found that the 5 cylinder engine's 100hp just aren't enough..... I have yet to read of any modifications costing short of $2000 that will increase the power of this engine to something, well, more substantial......all I'm looking for is 50hp or so. I'd like to get into the mid 100s, nothing spectacular. What are the best upgrades for this engine? thanks, geordie
