You cant argue with a cast iron closed deck block. And you can wind them to 10krpm with the correct work. I think subaru make PERFECT 200-400hp well rounded quick machines. They turn well they launch they jump they are a blast. A 300hp subaru to me is alot more fun then a 600hp evo. If you looking for balls deep power then inline six is the way to go. But if your lookin for 500-650hp an evo will do it no problem with some pistons. 700hp plus get an inline 6. 2jz or rb
Right now after extensive thought about selling my car to get something else, I have come to the conclusion that I would get one of two cars. Choice number one would be an 03/04 Cobra "terminator" with a 3.4l whipple pushing 800whp on E85. That would be a great car for the fact that I am in Arizona and don't have to drive but 15 miles round trip to school each day. My other thought is to get a Audi urQuattro circa 1983. The 2.2l inline 5 is probably the most powerful German small displacement engine in history. There are inline 5s that turn over 1500 ponies on race gas. The inline 5 can be expensive to build, but are very reliable when done right. The nice thing also is that the transmission is very similar to a subaru trans in that it is not a transaxle with a transfer case like an evo. This means you have symmetrical awd, reliability, and strength. I also love the group B rally heritage of the cars. I think the 4G63 is a great engine, but its greatness is reduced by the need for a built trans in pretty much any DSM under 13 seconds and pretty much any evo under 11 seconds. I know people in my area with mid 12 second DSMs that grenade the trans launching once at the track. A built trans can cost as much as the additional money it requires to make big power on a subaru. The Subaru will almost always be more expensive, although it is not as large of a gap when you start making bigger power where built engines are required.
