Default os .21 vspec replacement

I wish I could just buy another vspec , absolutely love this motor. Have you personally raced this motor and what have you found that runs just like it , I'm thinking of going with os speed , there are so many versions of that b21 etc , Las Vegas edition !? - I'm not sure what to pick and for the price I'd hate to get a motor that insane and has trouble tuning , a part of me is tempted to try the aTom gtr .21 I hear it's a copy , " I actually used some atom parts to keep my vspec alive for a few more gallons "
- if you could chim in that would be great

why dont you look at the OSMAX 21XZB VerII it is very power motor and has the piston and sleeve and the crankshaft from the XZB spec just has a simpler carb and you can get one for around 300 bucks and the 2090 pipe will cost you almost 200 xtra but its worth it in my book! Michael

I've been running v-specs for years. My father got one of the atom vortex motors and it has run just as well as one the old vzb's. You might try one those knock off rebuild kits from ebay, I've put a few gallons through one and it's held up so far.
