Per the factory spec book:
1.7 heads have 51.1cc to 52.6cc combustion chambers. 1.8 heads have 52cc to 53.5cc combustion chambers. 2.0 heads have 58.7cc to 60.2cc combustion chambers. So with a stock 1.8 bottom end and stock 2.0 heads, the compression would drop significantly. Jim |

QUOTE(jcd914 @ Apr 20 2018, 01:52 AM)  Per the factory spec book: 1.7 heads have 51.1cc to 52.6cc combustion chambers. 1.8 heads have 52cc to 53.5cc combustion chambers. 2.0 heads have 58.7cc to 60.2cc combustion chambers. So with a stock 1.8 bottom end and stock 2.0 heads, the compression would drop significantly. Jim Stock 2.0L crank and rods with 1.8L heads makes for a bump in the compression ratio. Put 2.0 valves in the 1.8 heads, and you make up for the non-optimal plug location issues with the increase in compression. Plus the 1.8L heads don't drop valve seats like the 2.0L heads. If you do it, make sure you run premium gas all the time. (IMG:style_emoticons/default/driving-girl.gif) |
