I called them to get the recommendations for my set up and asked about yours from what I could remember. For the following they said:
0.019 - 0.021 Top ring
0.021-0.025 Second ring

Stock 2.2L ECOTEC rings are recommended. For blown or
nitrous application it is recommended to increase ring gaps
to: .023 to .026 for top ring and .020 to .023 for second
ring.

From the GM Ecotec Book on Page 67.

Ring gap depends on your build. I assume you're going turbo again, Travis? If so, doing a quick search, I found this on Wiseco's site....Click

So, according to Wiseco, for a "Blown Race Only" engine with a 3.4" bore, you're looking at
Top ring = 0.022" gap
2nd ring = 0.024" gap


...which is more inline with what the GM build book recommends.




I have no signiture

Street moderate would be .017
