Im going b20vtec soon and collecting parts that I will be needing just to make the car run. What head studs shall I use for this build? I have an ARP b16 head studs but this head is a SIR II JDM, they should be the same right. What ecu can I run? Last, do I really need to use that b20 block with b16 ARP head studs? I think they are different part numbers compared to the b16 ones. Also did anybody ever hear about the vtec conversion kit made by Blackworks. Is that produuct okay to use.
