You can get close to that with ko4's and meth.

If I built the motor, would the curve improve dramatically??

Who put down 390whp w/ Tials?? Is that a realistic # I will see on a conservative tune??

WMi_S4

purchased it, as no1 has this running and tuned yet...

WMi_S4

THAT much??

Jeff 'S iv

was gonna end up running $10,000 WITHOUT building the motor. not worth it

Assuming you kept the rev limits the same, you'd have a small power band but peak power should be significantly higher with a bigger turbo. So the loss of some low end power would be negated by the huge increase in power across the rest of the power band.

But while you're adding rods, most people do valve springs and retainers and then bump up the rev limit. This means your power band stays about the same, but is just moved up some. AND peak power throughout the power band is increased significantly. So ya... big turbos + rods + increased rev limit = ftw :-)

that sounds alot more expensive than buidling the motor and doing RS6's or Tial's....

But most people just have new rods, piston rings, and bearing installed.

The stock pistons are forged and the crank and block are pretty stought so you should be in good shape.
