yeah they will do fine! but they are only 17mm bearings and not 19mm.
you can use them though.
but as marcy said, the standard rods are good for around 500bhp and you dont need the arp head studs either, in fact the oe nissan bolts i believe are better than the arp studs.
they are thicker than the 200sx bolts and can take a lot of abuse before they will move anywhere.
the stud kit just makes it a real pain in the asse job to remove the head, when the need arises (which it will if you use that cometic gasket)
i would also use a standard oe nissan head gasket over a cometic steel one, as you aint gonna be able to afford a head skim and block reface, so theres an excellent chance of the steel gasket being totally useless to you. there not good at the best of times, hks is the best but then you will pay around £150-200 for one.
