Good thing I made that up. Some FACTS are B20vtec motors (not saying there arent exceptions) Can rev high due to r/s ratios and weak stock sleeves. Just what I put in my previous post. So without building the block with sleeves, maybe even a block guard, apr studs and prolly some strong internals you wont be able to get full potential out of the setup. Type r/Gsr motors make power at peak rps, not crvs dont. Thanks for the imput tho 🙂 _edit I was wrong about the name though, I meant “crvtec”_ --- _[View the full topic](https://forums.speedlife.net/t/b20b-with-type-r-head/44157)._
