Could you answer me a question? I have a 1998 S70 GLT with a bad TD04 13G. I can get a good deal on a 15G. What are the pros and cons of switching to the 15G? Can it be done without modification, flanges, oil, water lines, boost level... Any help would be awesome.

 

13g to a 15g if it has the same flange should be a direct bolt on.

Angled to Angled, Straight to Straight, Conical to Conical.

Your stock boost levels should be fine.

 

Yeah, upgrading from a 13G to a 15G isn't that big of a deal, I mean everything should work fine. You'll lose some of your lower end speed though because it is a slightly larger turbo and you'll have a bit more lag.

 

I would like to thank each of you for your expertise in this matter. I will be asking more questions soon. Later, Jake...
