dbtk2 is on a distinguished road

You guys are all talking about turbo'* off eclipses and talons, and I don't really understand why. The purpose of the twin charged setup is to get the off the line power from the supercharger and then the turbo kicks in for the topend power, and also the supercharger will help the turbo spool since it will make the exhaust pressure greater quicker than an N/A engine. And a turbo off a talon isn't going to flow any air after like 4k or so on a 3.8. A 3800 is twice as big as those engines. You need a much larger turbo, especially since you have that blower to help it spool. The turbo on my STE is the same size as what is on a Talon/Eclipse and it is fully spooled at 1800rpm and I only have a 3.1L and NO blower.
