As far as adding a supercharger, turbo and/or nitrious to the 3.9, unless the motor is torn down and prepped for a power adder, the life span will be short lived... |

LS v8 can handle up to 400 hp... do we have forged internals? |

Has anyone on this forum or other owners that you know of spoken w/ Ford Racing, BBK, Holley, Edlebrock, Steeda, Anderson Racing etc., for a broader selection of aftermarket parts, such as a rear end gear, axles, stalls, emission legal/yet modified cams, upgraded heads, mass air meters, etc? |

MSRP: $40,600 Invoice: $37,300 Rebates: $6,000 + $1,000 Your price: $30,300 So a new LS V8 would've been $30,300 assuming you paid invoice and financed through Ford for the extra $1,000 rebate. I don't know if the rebates are still that high now. |

I know quite a bit about turbocharging and would very much have been wanting to play with a 24valve 3.0, an awesome motor by any means. I figure a solid 400hp on street gas should be a walk in the park. Anyone know where I can find more info on the manual transmission, as I could not find a search button in the forums. |

That being said, more power would still be good, just not through the awful 4.6L. Better choices would be the naturally aspirated or blown 4.2L Jaguar engines. They would actually fit under the hood (unlike a 4.6L) and would bolt up to the tranny (unlike a 4.6L). Lincoln should at least try offering the blown 4.2L on a limited number of LSes. Because everything would (seems like it should at least) bolt right in, it would probably be pretty cheap. |

Now, while working on both engines, I almost wonder if the 3.9 isn't loosley based off of a 4.6 if not entirely...? To me the eng config looks like a severely destroked 4.6 4v with a shorter deck and a more expensive intake. |

Anyway, my comments toward the 4.6L aren't based solely on reliability, but on having a crummy torque curve with no bottom end. When my V6 Mustang was in the shop once, the dealer gave me a GT loaner. I'm sure it was a lot faster than my V6, but it sure didn't feel it. The problem was the lack of torque. Same thing with the Marauder. I've driven Crown Vics and Grand Marquis, and a handful of Mustangs with the 4.6L, and I just can't stand that engine. |

http://www.jagweb.com/aj6eng/v8_performance.html The LS 3.9L is a slightly cheapened Jag 4.0L that has had the bore reduced .05mm for marketing (so Jag buyers get a bigger engine). Also, the Jags have variable valve timing, which the LS didn't get until '03. On the lack of bottom end, I hear you when you say it's ironic for such a comment to come from a 3.9L owner. However, the LS's 5-speed tranny does a great job at compensating for that. What's 1st gear on a 4R70W? 2.4? 2.4 x 3.27 rear = 7.85 torque multiplication in 1st gear. For an LS, it's 3.25 x 3.31 = 10.76. The 3.9L in the LS feels a lot bigger than it is. I'd like to see a dyno chart of it. It'd be interesting to compare area under the curve to a Mustang 4.6L. |
