SR20DE vs. SR20Di

Hi, guys.

Just wondering, what is it that accounts for the difference in power between the two engines? The Di one has only one injector, but is anything else different? Cams? Compression ratio/Pistons?

Can anyone tell me if it is possible to put a DE head on the Di block? I need a project for when I have enough money (not soon at all, but still).

Thanks for the answers if anyone knows.

oops, didn't see your thread before I posted mine...

hehe, but nobody seems to know the answers to our question anyway... :( I'll speak to my dealer and see what he says...
