    Ive found arp main cap studs for my build part number is ar203-5403

    These are listed on tuning developments as 4efte main studs

    Everywere else they are listed as 4age main studs,

    Can anyone confirm they are the same and will fit my 4efte before i place an order?

    Arp never made a direct fit stud kit for the 4efte they only made headbolts. U can use 4age studs listed on tuning developments site if i remember correctly the block and head will need to be machined to for them to fit as the studs are thicker than the headbolts.

    Met with the engineer and discussed this today, ended up ordering the 4age arp head studs (10mm instead of stock 9mm) and main cap studs

    Thanks i was talking about main cap studs (the ones holding the crank to the block) not head studs , but ended up needing that info about headstuds anyway :)
