Hello, This is my first post and I made a quick search about it and didn't get any relevent results. I recently brought a 1991 Integra GS with a swapped B20B (around 90000km on it) and the automatic tranny . Since I checked around to ID if I had the low comp or high comp engine, I figured I had the low compression one since it came from a JDM reseller and it had no Knock sensor and a serial starting with #3, I plan on removing the head and checking the pistons just to make sure. The engine seems to have all the B18a/b intake, fuel rail and accessory attached to it. (Guess they just pulled the block out and threw everything that bolted on the B20B right on). So since I am a little bit disappointed by the loss of power due to the low compression I was looking at these... B20 84mm High Compression Pistons Rings DC2 EK EG on eBay.ca (item 130326242859 end time 20-Oct-09 08:58:58 EDT) I am now wondering, -Will they fit? -Are they any good? (Reviews seems nice with NPR) -What kind of power gain should I expect? -Would you do it? I am studying to be a Auto Mecanic so I don't really mind opening the engine up and swapping parts but I'd like to know the opinions of people who know more than I do and I am willing to listen to any advices. Thank you for your time, and I am happy to be part of this community.
