Upgrading BorgWarner EFR Turbos
 

I’ve edited my question in hopes that it helps others in providing useful information.

Hi all,

I’ve searched a lot on this - between this site and all of Google. If Ive missed something then I apologize. I was expecting to find more on this subject but maybe it just hasn’t been done.

I’ve been researching replacing the BorgWarner IWG and RCV with Turbosmart units - ideally the twin port IWG and 100% recirculating BOV (due to placement of turbos and not being able to make adjustments). Please let me know y’all’s insight. Thank you.

Nobody uses the AAM twin turbo kit on here. The intercoolers are way too small and can't support an upgrade anyway.
