That's where the conversation stopped. How different is the valvetrain in the LS? Larger valves? Better valve springs? A possibility to use the LS parts to improve upon the current 3.0?

"Technically" it is a superior design but that does not translate to anything on the street or even in a touring car. Also for what it's worth both the M3 (8100 redline) and the S2000 (9100 redline) have a roller follower design just like the Duratec... Also the stock Duratec valvetrain can handle 8100rpm without batting an eyelash. Let me know when you have an engine that can handle that on a daily basis without excessive wear and oil consumption. Heck much less even have a need to spin that high. Short answer. It's not worth even looking at. 2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.

IIRC, Chris Reinke campaigned an SVT in Speed World Challenge for 2 seasons with a bone stock valvetrain and a motor that saw 8000 rpm on a regular basis. Granted, he could rebuild in between every race but did he? Nope. -Chuck Dienzo Black 98.5 E1 SVT #5022 of 6535 Born on March 16, 1998 "If trees could scream, would we be so cavalier about cutting them down?

Maybe that's how the Jag 3.0 gets 231HP in the S-type. -Auto Makor- -Experimentor -Station Wagonor- -Computerizor- I have a foot that is bigger than a foot. SuperChipFOR SALE

Take into account all the "extras" (DAMB, VVT, Intake, CR, Spark Curve, etc) over a normal Duratec and it's downright embarassing IMO. I had more then that with my 2.5L without even doing any engine or head related work. All bolt ons and home brew mods. (~192 = 235-238 crank) Then I added headers & duals... Exactly... 2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.

Exactly... so - your saying that with your same mods the 3L would be around what? ~270??? the Jag/LS motor makes more power stock for stock than the Taurus/Tour motor. Reason states that similar mods will gain similar power. Thus if you start with more you will always have more mod for mod. having said that - anyone know if the block castings from the LS/S-type and Taurus/Tour are the same? Reason I ask is engine mounts.

Reason states that similar mods will gain similar power. Thus if you start with more you will always have more mod for mod. OKay let's do a fairly equal comparison. 200HP SVT (00) vs 231HP Jag 10.25CR vs 10.3CR Both tuned for premium fuel 80hp/l vs 77hp/l JAG has all the extra "goodies" as stated in my previous post while the SVT does not. So a basic Taurus 3L engine at 80hp/l is 240HP. As an example - We've seen basic build full 3L engines with just SVT cams and stock everything else put down 195-200 wheels. That's 240+ at the crank. That's my entire point. So 231HP from the 3L engine with all those improved parts and better technology is Pathetic. Plus it's in a "company flagship style" Jag to boot. Some engine examples from the competition... The VQ 3.5 makes 74-77hp/l in the detuned form used in the Altima and Maxima. In the performance Altima, Maxima, G35, 350Z it makes 80-84hp/l The Jag is just LAME!!! It's output barely rates equal to the hp/l output on Nissan's 2nd level family car. (If you consider the Sentra a base level family car otherwise the Altima is the base!) 2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.

Yes, they use the exact same shortblock with 2 exceptions: 1) Main studs/bolts are in slightly different locations since they have a unique windage tray, pickup screen, and oil pan. Hole locations are the same. 2) Coolant cup plugs in valley of block are installed in different location. Jag/LS use the foward hole and plug the rear. All other Duratecs plug the front and use the rear.
