Hey all, I currently have a HDI intercooler on my car and after looking I think it used to be for the ct9. I tried making new pipes ect to fit but it could just do with a new intercooler tbh. I have a WEPR one here too which I bought for my old starlet to suite a td04 but on this kit the pipe work is all 2" hot and cold side were the HDI has 2" hot side and like 2.5" cold. I want to fit the WEPR one on but will it effect the cars proformance in a bad way? I will be running 1.5BAR at 270bhp will it flow the rate alright or too small and cause the velocity to increase and effect the air drag?

Thanks
