STG III - For the seasoned EJ veteran only! If you are looking for a great rotating assembly to handle 600-1000 HP builds you have found it! This kit upgrades the connecting rods to the Manley I beam Turbo Tuff rods with your choice of ARP 2000 or ARP 625 rod bolts. This assembly has been well proven to handle over 1000 HP when properly tuned! If you are building a serious racing machine to handle up to 1000 HP you don't need to look any further than this page. **Please be advised that anything over 600 WHP on the EJ we strongly recommend having the block sleeved. If you have any questions please feel free to ask** We make things simple, we make things easy, we are the best at what we do when it comes to building EJ engines. No one has as many options and can back it up with customer support and help when you need it! Whether you want to build a 2.0l high revving motor or a 2.7l stroker we have you covered, you want custom compression ratio pistons? We can do that too. Want to have the assembly fully balanced before it is sent to you? Got you covered there as well. You want your piston tops ceramic coated? Easy, just choose that option when you are building your PERFECT rotating assembly! BUILT EJ is the last place you will ever need to go for Subaru parts.
