The latest honda tuning issue has a feture of a dart block build up. Dart blocks have already been discussed here, but i was wondering the drawbacks to dart engines. They got a closed deck design made out of aircraft qualiy aluminum among many other race-conscience modifications. There made in b18 and b20 styles and are around 2G . Does anyone know of someone with a Dart Engine? Cause it seems like a great way to go, I just want more info....
