Can I put a VX engine into my 89 Honda Civic Wagon

I just bought this car and it is still in pretty good shape to be a keeper. The 1.5 engine with auto trans has 160,000 on it now. What do I need to know on how to go about doing it if it is possible? Where would be a good place to look to pick up a VX engine?

Shaving the head enough to get a significant gain in compression causes problems ie cam timing, hitting the water jacket. The best way to increase compression is with aftermarket pistons. If it requires you to run premium I still think it's a good deal. The extra power is desperately needed. You wont need as much throttle to get up steep hills. Besides; if you never give it full throttle, you're not going to get knock anyway.

Honda increased compression from the Z1 to the Y5.

I just reringed my motor. No honing. I didn't check the cylinder walls for wear. I know I should have but at the time I was 18 and it was only my second time in a motor. My car was taking a quart of oil every 200 miles. After reringing it it takes no oil. Still to this day after 65000 miles it takes little to no oil.
