Looking to get some opionions on what to do. Car is lagging and it's getting old. Mods are in my sig. stock motor and heads. I snagged a TA5469 new in the box unused for dirt cheap and I threw that on my car. Biggest mistake I think I made with this car. Thinking I can "grow" into the turbo. Should have left the stock Turbo in and just held onto the 54 for my forged/ ported iron build. Stock turbo is gone But this 135k motor is still hauling ass and running great. Just a dog from the dig with this 54 ,thinking of buying a used smaller turbo until I'm ready to go forged. PTC converter stalling the car to 3,000 @ 0 psi. Looking to get into the mid 11's with this car. Any opinions? any turbos I should look out for and snatch up? I mean can I do anything else without opening motor to help spool this this thing? TIA
