ITR? and compression...

Two seperate questions:

1. What is ITR mean?

2. What does lower or raising your compression ratio do? performance wise/throttle response wise/ ect. wise?

1.) Integra Type R

2.)Low compression = good to add presurization (aka BOOST), High compression = good for NA (normal aspiration).

simply put:
if you take your stock honda engine and raise the compression, you will go faster.

if you lower your compression, you can add more boost safely to your engine w/out blowing it up.
