To answer your question....Yes & No
Our website hasn't been updated since '05 (but soon to be revamped), so both specs and pricing have changed. They are prepped to our latest Stage 1 specs but with improvements that are not listed on website.
All Stage 1 engines now receive new upgraded and cryogenic treated apex seals and springs in addition to all the other new seals, springs, bearings, 0-rings, oil seals gaskets, assembly also includes a new Mazdaspeed metal front cover gasket (we've never had one of these fail or leak!)
E-shaft is checked for "run-out" then polished and thermal pellet installed, Side Housings are checked for wear and micro-lapped and ultra-sonic cleaned. Oil pressure regulator is pressure verified & oil pump is also clearanced & wear checked and tested.
**The "Stock" ported Engine and the "Streetported" Engine have both been sold as of 11/01/'11
