Borg Warner EFR 6258 .64 or .80?
I’m trying to decide on which 6258 to buy the .64 or .80 twin scroll. My power goal is +280whp with 8.6:1 CR, I will be using the Skunk2 manifold and Throttle Body. Which turbo would be best in this sort application if going to use 15psi? |
.64

Make a build thread, ask questions there so you can remember everything in one thread.
You have already read all this, right? https://www.miataturbo.net/engine-pe...g-ideas-83443/ Have you read any of the EFR6258 build threads? |

Then read this thread
https://www.miataturbo.net/diy-turbo...-scroll-96920/ There are no twin scroll EFR miatas that i know of currently. I will have one of two with an EFR 6758 Twin Scroll and one other guy who isnt on miata turbo is getting a manifold as well. |
