Well thanks to the Adrenaline my HX35/ K31 twins will no longer keep egts in check. My main problem is the 12 cm housing on the 35. I just cant see putting $350 in a used housing or $480 in a new housing into the 35. So I am looking for suggestions for a new secondary turbo. I really like the ball bearing units either Garret or Turbonetics, but I am not sure what would be the best. I plan on upgrading to Mach 4s in the future as well as new springs. I know orings are in the near future as my headgasket is going to let go sometime. When the head comes off for orings I will be doing some porting. So let me hear your suggestions. I am not set on a ball bearing unit I just really like them for the cool factor and fast spool up.

A larger housing on your '35 would be a nice way to improve things without spending a bunch of cash.

A 14nwg housing and a large external gate might be all you need to fix your EGT issues.
