My thoughts are on the extra boost the M35 runs and shitty factory dump pipe causing excess heat and shaft speed on the turbine wheel.
I currently have an a/market dump and soon to add a front pipe with 200cpsi cat and keep the stock cat back, unless I come across a factory option Nismo system. Will be interesting how long my turbo will last. I oil change every 5000km and rarely give it any stick. Having said that, last week I relived my younger years by going up against a VE SS manual and VZ SS auto. Left the VZ a good 3 cars behind and the VE sat side by side. Boy did he look shocked ?. I didn't stall it up for either.
