I can tell you it is like night and day. I felt like I had 100 HP too."

I gotta agree with this one.  When I swapped my tired quarter-million mile 
1.9 for the new Tiico, it was an incredible improvement.  Maybe a NEW 1.9 
would be on par with the 2.0 I4, but that would involve time travel, and the 
heads would still leak.

Any rebuild or new engine is a huge improvement over a tired old dog, dyno or 
not.  It's just a question of what you want and who you trust.
