I know the Skunk2 IM for a stock H22 was worse for about 3/4 of the curve and then gets you like 2hp on the top end - I’m sure the profile for the B-series stuff is different, but I can’t imagine the GSR IM is that weak. I would say there is no point in putting money into the TB/IM if you are N/A and internally stock. People make a lot of power on the stock GSR TB/IM. I think he’d be better off saving his pennies for some cams. > > This is pretty much just my opinion, so if someone knows definitively that there are big gains in the TB/IM for a stock N/A GSR I’d love to hear about it. This is exactly what I keep bringing up. Adding an IM/TB on an internally stock motor will HURT the power curve with the exception of really high RPM. Every time I say that people get pissed. It’s been proven time and time again, do your research. --- _[View the full topic](https://forums.speedlife.net/t/b18c1-swap-into-97-civic-ex/199238)._
