Depends on the power you're wanting to make! I've got the stage 1 or 2 I don't know. If you got the dough, check FFWD Connections website, he makes some killer strokers. Also, He has rotating assemblies if you plan on doing it yourself. But with slow boy, just pick the right parts, for instance: If you plan on making over 600 "wheel" HP, upgrade the rods to an I or A beam style, or Pauters X beam. They are rated to hold alot more power. Preferably an eagle chromoly 100mm crank is in order if you are going to be racing often, but a refurb will do fine, IMO. Pistons are up to you, and with the compression I would go no higher than 8.8 or 9. If you have a good tuner you could do the 9:1, if you're doing the tuning and are ok, with say DSMLink or AEM, go for the lower compression... trying at all cost to stay away from the dreaded knock, and a higher comp. ratio will inhibit it, not drastically, but you better be able to tune that puppy pretty tight!
Another big thing to consider is that your engine is not an XL Hoover vacuum, wanting more air. So build your head accordingly, the benefits of a built head is well worth more than buying an expensive ass turbo!
