Message	After dealing with a whole batch of bad lifters, I'm going to add a few more performance modifications to my NA top end. Does my final list of modifications justify a performance timing belt (Gates, etc.)? When do you normally upgrade or do you prefer to stick with an OEM belt in all instances? I'm planning to set red line to 7500 rpm. Here's my build list: -Fully ported heads -Ferrea competition valves -JWT valve springs -Ferrea titanium spring retainers -JWT 400+ cams -BDE Adjustable cam gears -New oem lifters -Full exhaust and pop intake -Nistune for tuning with wideband -Fidanza aluminum flywheel balanced to pressure plate -Aluminum drive shaft -370cc injectors I'm sure I've left out a few odds and ends. Do you think these upgrades justify a stiffer timing belt? Will I run into any issues running one? Thanks
