Very unhappy customer (NST pulleys).

See this is critical. Everyone expects things to last forever when it comes to anything Totoya which includes aftermarket bolt-ons. It all hinges how you take care of it. Cae in point is boosting a stock 1nz. You can run 6psi for YEARS and YEARS. this will net you roughly 150-160whp. This level of performance in this chassis is very fun yet stable. Start going up to 8psi+ and that longevity begins to pull back. You could go 25k miles or even 75k miles or more depending on how you maintain and treat the system. A pulley is made with certain alloys for certain tolerances. If you use it hard then the lifespan is shortened. You make a calculated risk. These statements I make here are general and in no way supporting anything. Just plain facts.

That's exactly it! I'm without a dought guilty of believing that. I'm sure there's more people out there that think the same way, because "hey, i'm replacing part xxx with an aftermarket bolt-on, surely it must be better, because (in some cases) it costs more than the original".
You're absolutly right! Aftermarket manufacturers do offen have different tolerances and standards than the original manufacturer and it really is unfair to try and compare the 2.

Ultimatly it's up to each of us to decide if we want the extra risk.
