The picture below was when I saw it for the first time.  I was running some errons out in the sticks and saw it.  It looked too mint.  Turns out everything was new due to a theft.  I picked it up the next day....

Before N After...

Before:  "The engine that couldn't." The HF D15B2 1.5L SOHC 8 valve 1493cc 62hp at 4500 rpm and 90 ft lb. torque at 2000 rpm to the fly not wheels.  Redline was at a whopping 5k rpm and compression was 9.6-1.

After: "The engine that could!" The JDM H22A 2.2L 2157cc DOHC VTEC 16 valve motor.  11/10/06 200 whp and 168 ft lb. torque.  Right out of the box with Custom 4-2-1 H22A header.  The header makes power.  About 230+ hp to the fly.  Compression is between 10.6-11-1.  Vtec is at 5500 rpm where the old engines redline was 5k rpm.  Redline is at 7200-7800 rpm.  This motor swap was a huge gain about 140+whp and close to 100+ft lb. torque.  3 times the power the stock engine made.  I am still getting great gas mileage between 25-30 mpg.  Bigger the engine the less gas is needed to maintain speed which equals better gas mileage.  Going up hills and mountains is a breeze.

"You get the best of both worlds power and great gas mileage."

1/4 mile trap speed was a constant 106 mph on street tires this past year.  We will be dialing the car in this spring and hope to see high 12's being achiveable and possibly on street tires.  We have plenty of customers running low 13's completely stock.

Here is a short video of the H22 Crx in action.  Just a simple drive by from a dead stop.  It pulls and pulls hard.  5th gear and still wants to pull.  This is my old setup.  No muffler, lil less power.
