The head studs are the ones that were reccommended on this site. They should fit both 1.9 and 1.6. Correct me if I am wrong. Same deal with the main studs. Got the info from here. Con rod bolts, I sent my rods to ARP for them to check and find correct replacement size. This is what they reccommend. I would have sent in 1.9 rods but no one sent me any. I will pass along my contact info at ARP if someone wants to send some. These rod bolts are for the 1.6 and 1.7. I was told they offered about an additional 20,000 psi of strength and a much greater shear strength. I do not know if they will fit a 1.9 The trans ring gear bolt kit is for the 020 tranny's. The oil pump bolts are direct replacement for the bolts out of my pump. I do not know if these are the same size as the newer 36mm pump people are talking about here on the site. Anyone know if the 36mm uses different size bolts?
Is it true there are two seperate lengths?Somewhere i heard you need to use a spacer in some cases.You sussposed to be able to tell by a c or s cast number.
