B & K series, SR20, RB26, 2JZ, and More - Top Engine Swaps

Honda F20C/F22C
Not an easy fit in anything but a S2000, but this motor is such a good FR 4-cylinder that people have gone through hell and back to just to get that 120hp per liter in their cars. We've seen these motors in Miatas, old Corollas, Starlets and old Celicas. You'll need the help of a fabricator like Andy Vang who's done several of the Toyotas conversions. If this swap didn't require so much fabrication to the firewall and transmission tunnel, I'm sure this would be more popular and further up on the rankings.

GM LS
Some of you might not like the idea of using a domestic GM engine in an import and I'd have to agree with you. There are some sacred rules you just don't want to cross. But not even I can deny the numbers this engine makes. With so much horsepower and torque, all from a naturally-aspirated engine, who wouldn't want that? Not everyone can afford the latest LS7, but the older LS1 engines are very affordable. As for the actual install, you'll have to resort to custom fabrication and wiring. RX-7 owners have been doing the swap for years and now we are starting to see more and more Nissans making the jump. Just look at many of the Formula D cars.
