[QUOTE="RedVenom48, post: 16133885, member: 166576"] Im not going to lie, its a commitment to getting strong parts. The alternative though is that little nagging voice in the back of your head and a potential boat anchor under your hood. 2 steps are pretty rough on the timing system. The lower crank gear and oil pump gears should be on there as a minimum. What should be considered MANDATORY is the tensioner arm pivot pins. Standard aluminum block pins are 8mm dowels with 6mm threads. They can shear off at the block under abusive stress (2-step, high RPM and load etc). Upgraded pins will require machining the block to accept 8mm pin threads. Available from Cobra Engineering, Accufab and I believe JDM Engineering sells a set of ARP produced pins. Picked up the TSS lower crank gear and the Accufab Pump Gears. The price on the Accufab OPGs is.... breathtaking to say the least. But after getting them in my hand, and knowing its made out of precision machined tool steel I can accept their cost. I picked up a Ford Performance GT500 oil pump. Fresh housing and high pressure valve with a steel backing plate and the Accufab gears should mean no issues with oil pressure. The Accufab dowels and cam spacers are REALLY nice pieces too. I need new primary chains, secondary chains and passenger tensioner, cam bolts and arms. My timing system is complete after that! [/QUOTE]
