I thinking seriously about trading my msp in for a msm, but i'm wondering about the stock turbo that comes on the miata. I've read it's a IHI RBH5, also I've heard it runs out of steam on the top end. Now knowing a good amount about Subaru's, i know people who own wrx's use IHI turbos that come stock on the Sti to upgrade the stock wrx mitsubishi turbo. Since those two turbos are interchangeable, I'm wondering if they would work on the msm. The stock wrx turbo seems like a perfect match for it, and it seems plenty would be available from the subaru forums. Just wondering if anyone has any info on this.
