    On a turbocharged 3.0L V6 the stock ford head bolts and mains have been fine and reliable, always fit upgraded rod bolts though.... I run a arp stud kit on the heads.

      Forged Con Rods, not decided on make yet there is a UK company producing them but seem a little expensive

      I am developing ITB for my engine currently as am moving to DBW, mine is charged and running silly power so I have gone for 50mm units. I looked at Jenvey but the conversion is 2k so I decided to design my own. This is a prelim mock up on my dummy engine, i will quickly progress this over the next month or so as I want them on the car ready for mapping in April.



      I looked a dry sump system but instead designed a new wet sump with large wings and baffles and trap doors, I have a motec ecu and log the oil pressure and it has eliminated oil surve completely, some of us run 305mm slicks and compete in the GT3 series so its well proven now and half the money the dry sump is.

      I use clevite bearings and ARP studs and bolts.

      I use Arrow forged rods, good for 3 times what you plan to run power wise and I rev the engine to 8000rpm... I have seen the xpower ones and the guy is pretty local to me but not seen them yet so can't comment if they are up to the job.

              How did you get ARP main studs? They don't even exsist according to ARP

                Joey Got a batch of them from ARP. I believe he still has them in stock. It's not in ARP's catalog anymore, but it seems they'll still provide them to shops ordering batches of them.

                    What a people using for Main and Big end bearings, I have a set of Clevite "A" bearings been told that the tri metal "P" bearings are obsolete

                    Looked at King bearings but they don't make a competition bearing for this engine

                    Andygtt can you tell me what grade of Clevite bearings you use

                      Im actually not sure... i have previously run the stock ford bearing so they can't be bad although that was when i only revd to 7000rpm ish... must admit i wasn't aware there was more than 1 grade of clevlite ones available for the engine.

                      should be an awesome engine once you are done.... how much room do you have under the engine bay? I've just developed this, hope to dyno it over the winter to see hat gains it made on my low boost actuator pressure.

                        Andy simple answer is no room in fact we will have to go Promod and come through the bonnet

                        Going to run shorter trumpets in the final build with one large foam filter to cover all the intakes
