Leave the car with bolt-ons. Use the tons of money wasted and buy a 2013gt500 and keep stock so I could beat the shit out of it and not worry about warranty.On my 06 I literally broke everything.
I'm the same boat your in. I had bolt-ons and spr never had much issues. Went turbo. Broken motor tranny. Had the motor "built" nothing but issues since March.
Like someone mentioned before, theres people who 450+ and it lasts years. For people like me who beat the shit out of there car the stock motor won't last. (didn't last lol)
On my stock motor on 7psi made 450rwhp. And I bent a few rods my first outing at the track. I had numerous of street runs and racing. I launched off the 2step and it just didn't take it anymore lol.So IMO its 50/50.
