    Any DSMs running the R2’s in a 2.0? I know they are advertised for a stroker. But duration stays the same as S2 with higher lift at 12mm.

    You can't compare cams with only the advertised duration numbers. The R2 has 6 degrees more duration at .040" than the S2.
    It's just they would fit better with a stroker engine but it doesn't mean you can't use them in a 2.0. Compare to the S2 in a 2.0, it would be a bit more peaky, narrower power band. you would have less low/mid power but more on top.

    Listen to the manufacturer. Call GSC and they will tell you the r2s are for a stroker.
    I doubt your going to find anyone running them in a 2.0.

    I only found Evos running them and a couple were 2.0s. Headgames recommended for me to use them. So just wanted to see if anyone had first hand experience.

    I have no experience with the R2 in a 2.0L. I don't know if this will be of any help, but just speaking of my experience. I was using the Kelford 276/272 12.5mm lift in a 2.0L which is supposed to be their 272 range cams that fit better in a stroker. It was definitely fine in a 2.0L. Just the power band was obviously higher than their 272, so I liked it in the track more than on the street. if it's mainly for streets then maybe you should go with the S2 if you want GSC's cams.

    Right on, they seem to be a nice middle ground between 272 and 280. Hopefully the perfect pairing on an auto car with a 67mm turbo.
