Hey I guys I need some help, I have the 9.8 turbo version and I saw a 10.5 on ebay that I want to buy. But is there a big difference between the two besides jus size? Or basically the question is when you upgrade to a 10.5 is it really noticeable or should I just stick with the 9.8 and be happy?

 

If you're not running a lot of boost, the difference is negligible.

 

Thanks bro that's all I needed to know

 

just a bigger hotside i would look around for a used 9 turbo they have a bigger compressor housing also might as well upgade the whole turbo at the same time

 

If you do this, don't forget about the clearance with the water pipe.

 

I'm going to b using the 10.5 how much modifying I'm gonna have to do for the clearance of the water pipe
