[Carl H]

well since i had crap luck finding a proper part number for arp bits i had to go out and do some research on my own.

heres what ive found and is aplicable to the rb20/25/26 unless noted.

head studs:rb20/25 202-4301rb26 202-4207

rod bolts:z32 dohc vg30 bolts were reported to work on the rb25/26 but will not work on the rb20 (rod bolts are too long for rod, verify length of rb25/26 botls)pn for z32 rod bolts 202-6004use sr20 bolts, may need slight trimming 202-6005 x2 (2 sets req'd if using kit)or alternatively order (rod bolts and nuts respectively)12x ar3.67-112x n502rb20 rod bolts ONLY : 202-6003 (l24 late,l26,l28 rod bolts)

main studs:this is from my measurements of my stock bolts and my blockrb20/25/26 except rb30, again verify lengths and sizes.3x am4.600-1lb 11x am4.125-1lb14x 200-851914x 300-8344

awesome.

thank you!

[eh?]

For RB25 rods, the arp SR20 rod bolts work fine. I didn't have any issues.

[Carl H]

said problem of vg30 bolts being too long on the rb20 rod... again keep in mind that if you choose to use vg bolts on your 25/26 make sure to get the dohc ones as the sohc is diffrent.

[eh?]

Not sure why you're d!ck around with VG bolts Carl, you're suppose to use SR bolts :P
