It sounded like a lifter…is this common on these? The car drove/sounded fine after warming up. I’m thinking I’ll change the oil (maybe the dealership put to heavy of a weight oil in)? > > Also- I’m assuming downpipes are the exact same for GPs and Regals? ZZperformance has some awesome prices on downpipes listed for GTPs…maybe I will get one. I need some better front brake pads and rotors first though. Tap is NOT common. DP’s are same. I have found that most of the performance parts are reasonable if not cheap for this drivetrain. > [@WTB: old school aerosmith shirt.... or any other old school band](https://forums.speedlife.net/t/wtb-old-school-aerosmith-shirt-or-any-other-old-school-band/37546/24): > > Not to rain on anyones turbo parade but there’s plenty of m90 setups running the same times and -100whp as the bulk of the turbo setups. you can’t beat the top end of a turbo but you won’t beat the low end of a blower…it’s a trade off, there’s no way you can declare one better than the other I understand what you are saying and there is truth in the statement. --- _[View the full topic](https://forums.speedlife.net/t/gm-supercharged-3-8-question/199163)._
