Both sets of injectors sold pending payment, also have a set of Arp main studs that were installed in a 4g63 block but never torqued up as went with standard bolts instead $60. 2 sets of evo 9 bee hive valve springs and alloy retainers. 44,000kms on one set and 60,000kms on the other set. I used a set of these on my evo 2 4g63 with 37psi of boost, 8500rpm and 272 bc cams with no float and previously ran a set on my 4g93 gsr with 410whp. 90$ each set
 
I think its like 11.5mm but they don't like big ramp rates like kelford 272,s unless you keep it below 7700. I do have a set of shims that would give them a bit more seat pressure though.
