[quote=“Inn-Tune,post:26,topic:40149"”] Buddy…no way that engine is taking a 42R or 45R. It would take it at low boost, but there’s no point in switching from a 35R to something that huge if you’re not going to really use it. The stock sleeves and semi closed deck design aren’t up to 35+ psi and that kind of cylinder pressure. [/quote] You misunderstood… That is why im keeping the stock block,and that will be built later down the road to be able to harness the power of a 45r eventually. Obviously there is no way I would try to put over 28lbs of boost past that stage 3 block. Correct me if im wrong but this stage 3 block is just perfect for a 35r mike? --- _[View the full topic](https://forums.speedlife.net/t/merry-christmas-me-v-subaru-built-motors/40149)._
