i couldn't find any info on what arp stud kit i would need. so does anyone have an idea? its a d15b7 block with a d16z6 head. thanks. also, i know i need a z6 timing belt, what water pump would i need? and are adjustable cam gears really necessary bc i know it will be a half tooth off without them. i want it to run right. and should a stock p28 run it with any problems? thanks guys.
