Digging up an old post I know. But getting the Tacoma back within days after the connecting rod let go and exited the engine via the oil pan. Well months later the engine is almost back together after being rebuilt with forged pistons, rods, ARP studs, new bearings, valve job, etc. Currently have the NST + URD 2.8 + a little nitrous. Thinking about pulling the nitrous and adding a 2.55 pulley. Truck is an 2009 so I'm running MAP-ECU3 and a 7th injector. Can I run that small of a pulley? Maybe need to add some methanol?
