Dude, get another 420a. The power potential for this engine is far superior to just about any other engine, except for maybe a VTEC or vvti (I think?), and that just wouldn't be worth the trouble. Unlike most other 4 cyliders out there, the 420a is operating WELL below it's potential in our cars. For the amount you would spend for an engine swap, you could easily have a new 420a power plant pushing 300+ HP.

The 420a takes it's design cues from such sources as Lotus, Ferrari, Porsche, just to name a few. That's all I should have to say.

Just my $.02
