I'm surprised that you went with the 6258. The 6758 would be very similar in spool, but have so much more potential up top. I think the 6258 will not flow enough on the top end and will be noticeable with the TQ sliding off. Time and dynos will tell though.

EDIT: I'm so glad someone is trying out an EFR on this engine. Can't wait to see how it comes out. These suckers are TQ monsters with the Miata 1.8L engines.
