Anyone know anything about the Buick Lacrosse?

Okay, I was part way right, the vtec guy probably got the idea from EGR valves

Kick ass, where iwork just got pre production brochures on the Buick LaCrosse. I can post more info on it if people like, since i stole one. They aren't supposed to be seen by the public yet.. Engine options are interesting- choose between the series3 3800 or the new 3.6. Personally i'd go with the 3800.

Since the 3.6 will be in the Lacrosse I will give you the info I was told.

Sounds like its going to be a great reliable engine.

Its about time GM makes a smaller V6 that can produce as much as what the dodge 3.5 has been producing for a few years. I still find it funny that GM has been using the 3.8 with only 200 hp for so many years. My 1995 Chrysler has a 3.5 that came stock with 214hp and 221 torque. The Ones theyve been using the last couple years have had 245hp and 250 torque. With out a super charger. Its nice to see GM finally Catch up.

that 3.5 mopar engine couldnot stay together

My 1995 3.5 v6 has 156,000 miles on it and hasnt been rebuilt yet. neither has my transmission. My engine leaks a little bit of oil but its still got plenty of power and can smoke a gm 3.8 that isnt super charged. My dads buick lesabre had the 3.8 and it broke a connecting rod at 78,000 miles and punched a whole in the block.

I have owned 2 chrysler/Dodge products in my life, both of them were crap, one couldn't stay running, the other leaked and burned oil so much I had to carry 6 bottles of oil with me where ever I went. These 2 vehicles left me stranded so much it was unbelievable. Since then I have owned nothing but GM vehicles, most of them with a 3.8. I now have a 1990 Buick Park Ave with 200,000 on it and it doesn't burn oil, it doesn't leak anything, and it has plenty of pick up.
Did I mention this engine or the transmission hasn't been rebuilt.
