99VETTE PILOT

What are the differences between a 05' LS2 / 06' LS2?

I'm looking to replace my grenaded LS1 in my 99' Vette.

Thanks all

There the same engine

There are a few small differences like the cam timing sprocket and other stuff. PM one of the vendors to get the definite changes.

Well, for one difference....
Starting with the 2006 model year, the LS2 now comes with a 58X reluctor wheel and new camshaft sensing, and is NOT compatible with pre-06 ECMs.

Yeah I read somewhere that there was a new 32 bit something or other new for 2006 LS2s, related to all of that I'm sure.

So I guess not even the stock shortblock is good for a trade in on a forged motor. They will want a 05 core for an 05 build-up and eventualy they will need your actual core for a build-up. Never buy a car the first production year.

I hope youre kidding about not buying 1st year production...
that's ridiculous!

Not in my opinion. You never know what putting 10, 20 or even 30k on a car can do real world use, not on paper. So by the next go a around they have more real data to work with. My opinion of course.

Yea, I'd much rather have the local Chevy dealer ripping the driveline out of my brand new, second year of production, 2006 C6 to get to the defective flywheel. No thanks!

I've had Zero problems with my 2005 C6. I'm off warranty anyway with my mods, but that's my choice. You need to remember that the C6 was on the road for a number of years racking up miles and lots of them, before we ever got our hands on them. I'm sure they made many adjustments to the car during that time. Really the first year we can buy them isn't the first year on the road. So saying never buy a car the first year of production doesn't really ring true. At least not my figuring.

The vast number of people would in hindsight have passed on the rear end weakness and future engine swap issues if they were aware of it ahead of time. I have had few problems myself but that doesnt mean I didnt wish I had a stronger diff. I dont care about the warranty myself, but I think that I should have waited a year or 2.

Ahh, your memories are so short grasshoppers.

Talk to anyone who bought a 1984 Corvette about first year problems. If I remember correclty there were issues in 1997 as well. Everyone knows that 1953 was a pile of junk. That is one of the main reasons I waited until 06. First year vettes are notorius for having major issues.

I bet if there are any older folks on here they will tell you about issues in 1968 and 1963 as well.

ALL cars have issues...

'06 Quicksilver Z06

The C5 had issues throughout it's entire run. In '01 there was the oil consumption issue. There was the seat rocking issue, the leaking battery destroying the BCM issue, the column lock issue, the fuel guage issue, the piston slap issue, the Premature Wear of Leather Material on Bucket Seatback Bolster issue, ......... many of these were issues which plagued more than just 1997 C5s.

The "first year syndrome" is a thing of the past. Auto manufacturers use enough CAD in the development now so that first year quality is not the problem it was. My early '05 has only been back to the dealer once to have the rear differential fluid changed (I do my own oil changes). Aside form that, ZERO problems after nearly 16K miles!

Did I hear someone say PISTON SLAP?
