The original JX .21 was an AWESOME mill!! Hate that they no longer sell them.... Was one of my favorites without doubt!

The VZB Vspec is still around though. With the right modification this engine is just like the JX as the JX was based off the VZB with a DLC coated crankshaft and some mild timing alterations with a more stout case. Too bad they don't throw the DLC coated cranks in them from the speed or old JX.... The promod Vspec did and its a GREAT long lasting engine due to it! I really like the bore/stroke and long rod combination. Made for an amazing power curve especially after some "Modifications" in the right places.
