Thanks for the info, Inferno (i was looking for your post)
Questions (if you are not sure let me know):
1) Octane level, is it much higher, and is this why some engines are running more HP than the American ones?
2) If we compare for example an Integra GSR or Type R from Japan and Here... are we talking about the same engine with different setup (chips...)?
3) My buddy is talking about putting a Japaneese spec engine in his Eclipse GST (blew the turbo, which in turn destroyed the engine), which one would be best for his setup (needs turbo and engine)?
I told him you should go with a 4.6L DOHC from the Cobra, but he doesn't like the idea

... just kidding!
