I have talked a little bit about this in my introduction page. I have a B20 bottom end thats completely stock and a PR3 head i wont to put on for CRVtec and a 75 shot of nos. i was wrried about the sleeves but peope are telling me the rod bolts will fail because they wont hold the revs and told me to look into the arp rod bolts. I plan on building the motor for boost next winter and no one is sure about if i have to have the stock rods machined for the arp rod studs im looking to know before drop alot of money into something thats just gonna be getting rid of next winter. also i wanna make sure that this is the right part number 208-6001, says 1.2L 1.6L & 1.8L M8.
