Re: 2006 TJ Replacement Design
Actually the V6 predated the I6 in Jeeps, so reverting back to one would
still be in keeping with the "Real Jeep" tradition. Making one with the
appropriate low rpm torque peak, now that would be DCs challenge. Who needs
a Jeep with a 7500 rpm redline?

Re: 2006 TJ Replacement Design
Actually the V6 predated the I6 in Jeeps, so reverting back to one would
still be in keeping with the "Real Jeep" tradition. Making one with the
appropriate low rpm torque peak, now that would be DCs challenge. Who needs
a Jeep with a 7500 rpm redline?

Re: 2006 TJ Replacement Design
Actually the V6 predated the I6 in Jeeps, so reverting back to one would
still be in keeping with the "Real Jeep" tradition. Making one with the
appropriate low rpm torque peak, now that would be DCs challenge. Who needs
a Jeep with a 7500 rpm redline?

still be in keeping with the "Real Jeep" tradition. Making one with the
appropriate low rpm torque peak, now that would be DCs challenge. Who needs
a Jeep with a 7500 rpm redline?
