so the flow rate of both the xtr and g2r is 49lb/min.....i'm curious to know what the difference is between them, may have to reach out to blouch for that. but based on the flow rate, and the fact both have 8cm or 10cm hotsides, so no difference there, you'd think it would make the same power out of each...my only guess here is that maybe they lightened the turbine wheels and get a little faster spool up and transient response? i'm just shooting in the dark here lol

I’d have to go back and look again, but I thought the 1.5 xtr was a 49lb turbo and the 1.5 g2r was rated at 52lb of flow. All while having the same size wheels. If spool is basically the same, the g2r seems like a perfect 400hp street turbo which is my end goal on 93.

i'm excited to see people running the g2r, i think it could beat out the 1.5, which is my favorite of the stock location offerings i have experience with (which, from working at a shop, is alot lol)

I know! I’m ready to see some 1.5 g2r results. Be really sweet to see graph overlays of the 1.5xtr vs the 1.5g2r.
