    Supercharger and wheel upgrades on 2018 gtr 230

    Does any one know what charger comes with the 2018 GTR 230? I thought I read it used the same charger as the 300's, however the PN is different. Can the wheel be upgrade to a ET 135 or ET137? I would like to add more boost to mine. So far I have a 4" Intake and Riva tune. Would like to get 75 to 78 top end. I would like to spin 8500 to 8700 RPM, and yes I will be putting springs and retainers in.

    Thanks Brian

    Not a 300 charger but the regular 255, you can add the 300 charger but would need to change a few parts.

    So I guess that means I can drop in ET 137 in that correct?

    Pull the wheel and measure it. Then you will have your answer for sure.

    Supercharger in the 230's is basically the same as a 260 but the "maintenance free" version. ET137 will work. Highly recommend dropping in a cam.
