woahhh! great work! I was wondering a few things, I've watched lots of builds but never felt like asking questions, this is the first practical looking setup I've seen, compared to some.

May I ask;
What makes this so efficient? An engine made for a larger car able to move the smaller car much easier perhaps, or is this a particularly efficient engine? I don't know enough about civic models to begin to understand the HX/DX mess of acronyms...

How dangerous is the "lean burn" for the engine? while reading performance modification threads for supras and such (I drive one) I have often seen that a fuel mix that is too lean will burn up the engine. Perhaps that's more dangerous with higher compression and turbos...but I would assume it risky here too.

Why don't car manufacturers do this sort of thing more? If anyone could swap in this engine and buy some engine management tools...you'd think that car manufacturers would jump on the bandwagon. I'm sure that some amenities may be sacrificed since I skipped a lot of the thread, but surely it's driveable... is it very tricky to get it to run right?
