Hey. I posted this question in the general discussion area, but I have not gotten any responses so I thought I would post in the actual GT500 section. I currently own a stock 2010 C6 base. I have been pricing out a few things, and if I decide to go through with it, I am looking at getting a UPP twin turbo kit with meth injection and running 650-700whp or so.
However, once I add the price up to what I have already paid for the c6, my total cost involved will be around that of a used 13-14 GT500. I have always wanted a GT500. In addition, I am thinking that there might be less "hassle factor" in dealing with owning/modding/working on a car that is boosted from the factory vs had an entire twin turbo setup fabbed into it. There are a few concerns I have going with the GT500 though.
1. It's much heavier, and stock vs the TT c6 I imagine it would get walked pretty good, and need an additional 100+ whp over a c6 to even be able to keep up. I never had any illusions of being "the fastest" though, and the fact of the matter is that I have never owned anything over 400whp, so I think I would be more than happy with the stock power level of a 13-14 GT500 until I decide to mod it. Plus, like I said, I have always wanted a GT500, which brings me to concern number 2...
2. I was thinking that going with a 13-14 GT500 would also be beneficial because, if/when I did decide to mod it, 650-750 whp would be much safer on the 5.8 vs that same power range on a stock LS3. However, I have also seen a lot of posts on here that indicate some people have blown 5.8s at around that same power level, in addition to breaking axles, so now I'm wondering if it really is that much "safer". A bigger issues though, is that if I did blow the LS3, it looks like I could build a new motor (forged 408 or something along those lines) for $10k or so. On here, I have seen a few posts from people who have blown the 5.8 indicating that it costs $20-$30k for a rebuild/new engine! Is that really the only option if a motor is blown on a 13-14 GT500, or is it possible to build something else and throw it in? As much as I'd obviously like to avoid blowing anything up and plan to stay under 800whp, it's something I would want to consider given the potential of breaking stuff once modding starts.
3. I live in a state where I need to pass an emissions inspection every few years. The inspection just consists of an OBDII check for no codes and at most one not ready. No visual inspection is done. One nice thing about GM vehicles is that you can actually "turn off" the emissions checks in a tune as opposed to just making them not ready, so the car would still pass even if i have catless exhaust, which would be needed with meth/E85 from what I understand. Is something similar possible with a 13-14 GT500, or would I have to get catted x-pipes?
Any advice is welcome, thanks for taking a look!
