BTW... the S54 is for the MR2(relocated shifting levers)
And yes a 5speed 4banger is a lot of fun! It's been said to be equivalent to an auto v6.
Whereas the 5speed v6 is the equivalent of an 5 speed 4 with aftermarket turbo...
Your in the states so a 5speed 4banger would be easy to find(well easier than canada!), and you save on the insurance and gas cause it isn't v6. Like BigBird said, lot's of fun! If you learn how to use the torque produced by the 5s, you can also surprise the dudes with civics and custom pipes!!
