I don't know why I was thinking MTX2. Since it's a three, some slightly later engines come into play like the Mugen MR-12 and X12, the first gen Sirios, even the first OS rear exhaust 12. Also, while I don't have the motor anymore, I do have a mint Rex RER 12 head off a motor I ran in my 3. If you find a motor but it needs a good head, I can hook you up.
