Good morning! I have an xc90 with the 2.5t, and it is self destructing. The reason I am posting in this forum is for performance related advice on the 2.5t. It seems this forum might have more performance minded owners than the XC forum. I am impressed with how well the 2.5 motivates my overweight XC, but you can always want more, right? Since most of the used motors I am finding come with no turbo, and I am concerned about the health of my turbo, I am figuring on either rebuilding mine or replacing it. Are there options to consider with the turbo that could improve the vehicles performance and drivability? I noticed a compressor bypass kit that IPD has, and also compressor wheel upgrades available else where. I know a tune will be necessary to make the most of any upgrade, are there some basic things I can do while replacing the motor to put a good base together to make the of an eventual tune?
