I'm started my A6 buildup (read sig) and i was wondering if i should get new rod bolts (ARP). If so do i need the 8mm or 9mm bolts? I dont really think i need them, i'll probally just get OEM new bolts.

BTW it is revving to 7500rpm, nothing crazy

 

How much was your total cost on building that a6 beast??

 

i'm not finished with it yet. I got the block and head free (both from A6 with 130k on it), the head will have Delta 272 cam ($80), JG Spring w/ stock retainers ($120), and a mild port job i'm working on. The block will have P29 pistons ($210 with rings), shotpeened and balanced rods ($60), and i'm debating if $105 for ARP head studs is worth it. I might go with new stock ones ($56) because i'm only revving to 8000rpm. Oh yeah and a Y8 head gasket ($35).
So grand total is somewhere around $550-$600 for the whold build. If I hit 140hp i'll be happy, the motor is being built for endrance not max power.

d series are tight, and from the facts pretty cheap to build up

 

get the head AND the rod bolts. i believe it is a nessesary precaution. i did.
