As for the oil pump case, I can see and feel the scratch marks, but they dont seems to have lost much material, but I'm sure the clearance between the gear and the walls is important
I will probably have to go with acl unfortunately if I go with new, I just cant afford a new pump while I'm unemployed
It's not about the oil pressure or horse power, it's about its production quality. The link below is what you should be careful with an aftermarket oil pump before installing. Even it's new, check if the gear cover sits its position correctly and all clearances are fine, if not, gears wouldn't spin smoothly and the gears would eat the case. If those are OK then it would work just fine. But of course Mitsubishi pump has the best quality.Ok, it should be a medium build, going for about 450whp, eventually might go up to 600, so yeah that sounds good. I'll be sure to watch it if I go with acl
It's not directly related. To engine speed, yes. I had run the ACL pumps without any issues. So from my experience, I would say it would be fine if you would be careful with what I said above.Hmm, it even says for low boost rebuilds an ACL, I might have to find some way to pay for an oem one, if I cant find a used one that is
I think I went with 20w50 because I had no balance shafts (I thought there was a second reason I would need thicker oil, but it's not coming to mind)
For break in, I used the cheapest 20w50 non synthetic I could find, and also a zinc additive that was recommended,
20 minutes of 3k rpm, change oil and filter, then 20 min drive, getting into boost and decel to seat rings,
Then onto valvoline VR1.
It was obviously to high pressure because the bearings were backwards, so I don't know what it would have looked like with them correct, I know I have at least one more thing of vr1 oil
(And thank you, means a lot, but I'm now making headway thankfully, also I'm glad you made it through the whole thread, I know its long)
Yes because of the larger radius. But he uses King XP bearings. The king XP bearings already have narrower design for larger radius. So it would work without making the bearings chamfered. I always use new Eagle cranks without making King bearings chamfered, I have never had any issues.1. You need to chamfer the rod bearings. Eagle cranks have a larger filet on the rod journals, so the edges of the bearings need to be chamfered. This is why the other rod bearings look like that.
ACL pump would work but yeah the oil pump is one of most important parts, so if you can go with the OEM, that would be the best. No doubt about that.I'll wait one more day on trying to find a used oil pump, then I'll probably get a new oem one, I found one for about 300 including shipping, it's just to important of a part, and I dont trust myself to check and guaranty that an acl pump would work properly.
Here is the link, should be legit, not sure
