    high volume oil pump?

    Okay guys ive looked around and most of the boosted setups are running the oem oil pump. we just took the bottom end off and we have killed the the main bearings the middle two. we are gonna go back with the ACL bearings this time and have the crank turned.

    The question is we never had the engine run low on oil so we arent real sure how it starved. but we want to keep it from happening again. so is there a high volume oil pump that anyone uses?

    I know that Toga makes one, has anyone used one? and we have the f22b DOHC what oil pump should we go back with?

    Thanks in advance.

      one of my old teachers has a turbo GSR... and he had a toda oil pump, and that actually failed on him.. so i would be weary around that one, i believe he is now running a type R oil pump.

            hondafan had his done i believe.

            I personally have the circuitworx oil pump gear installed into a brand new oil pump housing and this is what i would suggest with HIGH hp boosted setup. the one for the h22 works in the f22.

              I know some members here have modded their own, no diy on it though.

                Post your close ups of the bearings and I'll let you know what happened before you go spending money on an oil pump.

                  can do.

                  The 3rd main had scoring on the crank, mike said its a black spot in the middle, i didnt get a pic and hes already put the pan back on for the night, so ill have to get tomrrow, hes pulling the engine as we speak.

                  we havent ever run it low on oil, and havent over rev'd it ( as far as we can remember) I do know that before this started we had some over heating issues, we arent quite sure if that could of lead to all of this, we just want to make sure when we put it back together that we dont have this issue again.

                  Kinda wonder if because we have a large turbo on the car, when it starts to spool it spools very fast, could it be slinging all the oil out of the areas? we are running 8-11psi daily and the afr's are always fine, so no issues there, we did a compression test and it was good across the board.

                  Any ideas would be great help.
                  here are the pics
                  #4 main

                  #3 main

                  #2 main

                  #3 top half


                  I think i have those numbers right idk,

                    So only the mains were fucked? Those were all spun bearings fo sho.

                    Are these OEM bearings that the motor had, or you replaced prior to boosting? What was oil pressure like at idle, 3k and at WOT redline?

                      holy buckets! there usually are no issues with main bearings on a honda engine.

                        only the mains - and this is the second engine we have had only eat the mains. the first one was due to low oil tho.

                        i dont know what my pressures are cause we dont have the gauge installed, and yes those are oem we havent replaced them.

                        if the spun they sure sat back down in there places well, course i know nothing about this stuff.

                          The turbo you have on there is not "large" really.
                          The turbo cannot really "sling oil" all over the place inside the crankcase.
                          One thing i would start to look into is some type of crankcase breather which is a solid posibility for what happened. usually though the turbo will blow from crankcase pressure pushing air backwards through the oil return line. but this is also possible if the pressure in the crankcase gets too high to cause air pressure to force the air out of the main bearings. usually though the oil pressure regulator within the oil pump will compensate by raising pressure very high before air pressure can get high enough to blow main bearing but even with this factor too much oil pressure can cause the same problem.

                            So those are Honda OEM bearings?

                            That's weird. How many miles did that motor have? To me, it looks like the coating on the bearings started wearing off due to one or a mixture of the following: contaminated oil, old oil, over heated oil. I'm thinking the latter since you mentioned over heating. If the oil gets super hot, it can't lubricate. This caused improper bearing clearances and starter wearing the coatings on the bearings off, which causes spun bearings.

                            Are you running coolant lines to the turbo? I'm thinking that could have added to the heat(when you over heated) of the oil.

                            Either way, mic out the crank and the main bores to make sure everything is true. Replace with properly sized bearings and then use an OEM Honda pump, either modified or not. I don't think pressure was your problem one bit.

                              the motor was supposed to be low milage its been in the car maybe 4 months.
                              the turbo only has oil lines. no coolant lines.
                              we change the oil regularly and only run full syn mobile one .
                              mike says the bearings were not spun cause the tabs we still in tacked.
                              im not sure if we need the oil pump or not but anything to help it not happen again is fine w me.
