Hi there
Really depends on budget and target,but as you are said,you want 500bhp then I would go too with 2.1L as above SJ
Advanced Automotives or Lateral performance and many other companies selling their stroker kits...
Crank this depends,if you are want go with 2.1L,most commonly used crank is EJ257 crank and stroker pistons and rods,second option is go with EJ207 crank and longer rods(+2mm) and stroker pistons,this combo is used on HKS and Cosworth Stroker kits
About the rods and pistons,we are run Cosworth pistons with Manley rods which has been OK for that power which we are run,good pistons are too Wiseco and rods,this depends on budget,but you can buy K1 rods for nice price(they're slightly expensive than Manley,but not as expensive as Carrillo/Cosworth) and studs,I would go with standard size ARP head studs or Cosworth 11mm 260k psi and I think they don't need to be machined
Hope this helps and good luck with project there
Thanks,Jura

I run a 2.0 WRX block Sti bottom end rebuild from Andy Williams at pp@wms-racing.com with large capacity oil pump. The block should be just over a grand. The other issue you have is you do not have AVECs ( like me ) so you will loose the power gains that these heads bring , and to be honest if you are looking for over 400 you should really think about these as they flow better than the WRX heads. So its time to think about a late or scrap Sti for the diff-box and engine, then go and stroke it as described by above contributors. Also take a look at the Leaderboard, and you will see Tweaks has just posted his RA's figures. This will help show you what you can expect and what it takes to get there. Enjoy.
