Yeah, GM has replaced some LS7's but mist of the taboos happen on track and GM has denied a lot of them too. I provided proof about the LS3's, what have you got since you declare its wrong? You have no idea what it takes for a 996 tt to beat a z06. It takes very little, and yes the reliability would be better for hard driving.

 

Lets not lower to insults, the fact is if he went to a track day and the motor popped the Corvette would cost him 0 and the Porsche just south of $20k if not more.

 

Insults? For stating that you haven't done your research and therefore don't know what you're talking about? Oh my bad.

GM has denied many a warranty, and the 996 TT motor's going are very few and far between. So while the Z06 owner MIGHT not have to pay for a grenaded motor, he will be missing those laps the TT is still driving because his motor is still in one piece.

 

You're spouting rumor, not fact. At least give us a link or two in the Corvette Forum for guys that have lost a motor.

Just cause you say it, doesn't make it fact. You don't believe everything you read on the internet, do you?

Former C5 and C6 owner who misses them

 

are you guys saying that Chevy will warranty a motor that has been run on a race track? I don't think the warranty argument is valid when talking about racing as owner will probably have to pay the bill. I do agree that the porsche engine will cost a lot more to replace than the vette motor, and that is definitely a factor when racing on a limited budget, but if you have to replace several vette motors for every p-car motor that kinda nullifies the cost argument as well. Not sure if that would be the case.

 

I posted a link already, and there happened to be an additional video posted the same day in the road racing section. If you know enough enthusiasts you know someone who's lost a Z06 motor. I'm not posting any more links, look them up yourself. They are there and plenty more vids on YouTube.

 

There are a few " ways " to have an engine replaced under warranty. And for less than even a stock Metzger will cost you an LS7 can be built for 600 rwhp and for road race conditions N/A that won't have any problem being reliable. There are so many of these engines now that the engine builders well the good ones like Katech know how to make them last. If the LS7 was so bad it would not be the basis for a competition race engine would it?

I am debating a similar decision right now and $40k buys me a lot more Vette than it will buy me 996 Turbo. I guess it depends on what you want, if its only a track car than the reliability of the Porsche would be great. But again its a matter of luck. A $20k engine replacement for a $40k car brings a lot of other questions into play.

And the OP is considering trading in a car that he knows the history of and that still has a 100k powertrain warranty on it for an unknown 996. If I were him its not a jump I would make. Especially as the 996 TT's get up there in age and in miles and having seen how some owners tail off the service attention as the cars get older.

 

This forum is full of people that lost a 996 Turbo engine, so what does that prove? How many people adamantly post when there engine is running fine usually? I understand your bias and hatred towards the Corvette since MTI screwed you over but lets stick to the facts here instead of You Tube or forums.

A stock 996 TT is not faster in a straight line or on a road course than a stock Z06. So to even have parity with the car he has now that is still under warranty he will need to modify the 996TT or buy one modified. I think it just comes down to what the OP wants in a car some of us like Corvettes some like 911's but we make our decision with our money. So let's try to keep this objective and answer the questions that were asked instead of going off on tangents.

 

you are talking out of both sides of your mouth. You and I both know the race ls7 and street ls7 have little to do with each other because that was a gt1 motor. The new motors are based on the ls3 which why the new car is called the zr1. And you keep talking as if there is even remotely the same probability that the mertzger would blow up without something like a money shift which its not. And yes built ls7's have blown up too and I would bet a katech motor costs 20k just to build, NOT including the motor. Unless prices have gone down since I was building mine.

 

I have been thinking about selling/trading the 'ole NastyZO6 and getting into a P-car...

I have been thinking about this a lot lately and am glad I found this thread. Gives me some decent info/thoughts to process.

 

Look you know 996's....so do me a favor. Don't speak on Vette's unless you have a clue what you are talking about. The GT1 Corvettes do not use a Gen IV V8 at all, not a destroked LS7 or an LS3. The Metzger is amazing but you make it seem like a 60k mile , never serviced motor would last to 200k with Alpha 28's and at 1.2 bar with every mile at 6000 rpm or above.

I will concede this argument to you just so we can quit derailing the OP's thread. OP what are some of the questions you have that can be answered without any bias?

 

Where are the full of blown up tt motors? Especially ones that weren't heavily modded? That sounds like a generalization which is false at best. There are very few comparatively. I don't hate corvettes, stop twisting my words.

 

There you go adding words again. You are the one who claimed the ls7 was race based. Well who's racing it then?

 

Did I put words in your mouth or is it simply you have no idea what you are talking about?

 

They used to race with the LS7 in GT1....ok so lets get this thread back on track. Does anyone else have any real world experience or unbiased opinion they would like to share?
