Anybody on here go from the 370z to the bigger Z06?

cjwsrt6

Title states it, anyone go from a 370 to a c6 wide body, grand sport or z06, even a c7 grand sport? If so what's your thoughts? Obviously they're great cars but is there anything you dislike?

Wider, how you sit in the car makes it feel harder to maneuver with wide hood. Noisy cabin. Less reliable stay clear of the c7 lots of engines having problems. The C6 zo6 has valve train issues causes engine to crap out.Anything with ls3 engine is a sold build However they have issues with a wobbling harmonic balancer, Torque tube bearing issues, electrical gremlins. Nothing real expensive but definately less reliable then our Japanese build. I honestly believe for the price the Z and corvette are the best bargain for anyone's money. They just perform and look better then cars that cost two times as much IMOP. I actually moved from a vette to z.
Good luck!

Can you be more elaborate about the C7 engine problems thank you.
I know you came from a vette to a Z.

Did you actually own a C7 and had a first hand engine trouble experience?
Thank you for sharing

I've read about the valve issue, most I've seen in the 7 liter is pre 2012, I'm looking at a 2013 if z06 or grand sport c6.. noise isn't a big issue, with the targa or convertible I'd have more wind radio and exhaust noise to cover up.. I have not seen any issues on the c7's I'll have to look into this more

Crux

Just about everyone in MAZOC in the mid-atlantic section of this forum have made the switch to C6's and C7's.

I had the honor of chasing Z1NONLY (driving bladesofchaos' C7) up and down the dragon last year. I gave him a lot of space

I have both. The C6Z06 is nearly 6.5" wider, 3" lower, and over 7" longer than a Z34. Wheelbase is about 5" longer than that of a Z34. It has less ground clearance and more front overhang, so scraping is a problem that occurs more.

Problems are always there in any vehicle, they are just different. Replacing the exhaust valves and their guides improve reliability. Mine now runs Ferrea SS exhaust valves and brand new guides. At least GM decided to forego the electric steering column lock since the last model year of C5, so no C6 is plagued by its malfunction.

Some of my dislike is the extensive use of electronics in the C6; door handles are soft buttons, nothing mechanical about them. The keyless system is about as robust or fragile as the one in my Z34. Cabin noise transmitted is about the same since it's largely dependent of the type of tires.

With a much larger engine and a lighter chassis, a C6Z06 demands more self-control and driving skills. Tail-out happens on demand yet it's docile enough for daily driving. However, while my wife drives the Z year around (even in the snow with proper winter tires), the Z06 is much less useful due to its very low ground clearance.

All those said, what's your intention for a C6 Z06?

Honestly, it'll get driven maybe 100 miles a week and used for autocross. I will have a daily for work and take this out when it's nice weekend or date night that's about it

Oh yeah? Im Asian and Im undeniably goodlooking in and out of a vett!

Your reasoning is immaterial. Case dismissed!

POS VETT

That would work. Proceed

Here is just one thread: Never owned a C7 but I was considering until I started doing research that is why I own a Z now...nothing is more reliable.

C7 engine problems, would you by a C7 today? - CorvetteForum - Chevrolet Corvette Forum Discussion

Grand sport is fine it uses the LS3 not the LS7. All Z06 LS7 engines have the valve issues... lack of valve concentricity with the valve seats, and the subsequent valve guide-valve wall wear. They do wiggle tests and band aid it but that concentricity issue needs more work than what they do to "fix it"...I wanted a z06 bad until I read about this mess....I would focus on a GrandSport or the LS9 engine! That is the king of Corvettes IMOP the ZR1 ..it essentially has the more stout LS3 engine but with all redone supercar internals to handle the power/supercharger etc....but then your talking 55 to 65k and in comparison to the Z/Nismo there is NO way it is worth two times as much...( you can buy 2 Nismos for the price of a Zr1???) I am a financial planner and that did not make sense to me...
I owned a Hellcat too ask me about that POS...lol

280z/300zx

I've been a Z owner since I was 17. Started with an 84 300zx (still own it), then when I was 18 I bought a 280z (still own it). Bought an 09 370z touring sport and after a wreck I replaced it with a 2010 NISMO. In 2014 I replaced it with a 2012 Grand sport Vette that only had 2200 miles on it. Didn't want the C7 at the time and always loved the C6 GS.

In my opinion the C6 GS is obviously faster, handles every bit as good as the Z in tight turns but at high speed turns the Vette is better (I'm assuming due to the wheel base), the interior is quiter, and the Vette is so much easier to have fun with. One of my biggest issues with the Z with the VDC was too strong for daily driving. Wouldn't let you have any fun, but with it off was not safe for daily driving. The Vette's system allows you to get the back end out or spin the tires with in reason, but will kick in should you get into trouble. Nissan really needs to take a lesson from chevy on this issues

The Z did have better materials compared to the Vette, but fit and finish in my opinion is the same. My NISMO rattled all the time on the fwy due to the harsh suspension. The Touring Z was better and more similar to the Vette.

As far as reliability, the Vette has been problem free except for the known fuel leak issue. The connector at the top of the fuel pump tends to crack with age. Chevy has some funky VIN coverage on this where some cars are covered and others aren't. Mine wasn't so I had to pay out of pocket. The harmonic balancer issue is typically only on the early models. The 05-06 also had issues with the rear diff and half shafts. For the most part I'd say the Vette has issues just as the Z does. I don't think any car is perfect. I also don't think the Z is any more problem free than the Vette. While I had my 370z I never had a single problem, but I'm sure if I still had my 2010 I would have had the steering lock issue by now.

Overall, I'm happy about the switch from the Z to the Vette. Being I bought used I only paid slightly more than what I paid for my NISMO and in the end I got a much faster car that is also more fun to drive, without have to sacrifice anything of importance. Both cars are low and scrape very easily, but the Vette is even more so given the GS has the lower lip piece.

My plan is later this year to upgrade to a 2018 GS Vette now that they are out.

Yea, what he said. The ONLY thing I cant stand, well maybe not CANT stand isnt accurate, dislike very much, is C6 interior. Albeit its better than the C5, but thats the lowest bar possible as a public toilet is better appointed. Im talking porta potty stuff too. First world issues huh? Boo-hoo.
