Fp 4R cams and FP beehive springs and retainers.
I do not recommend stock springs with these cams. These beehive springs are rated just under kiggly springs. I had no valve float and no problems with the springs to 9200rpm. On my old 70mm turbo I had minimal low end power loss with positive boost coming on at 3300rpm and hitting 1.8 60fts without a 2step on street tires. There was great mid power and pull hard as hell up top spinning tires over 100mph in 3rd gear.
$640 shipped.
