tech9 Posted February 15, 2009 Share Posted February 15, 2009 Are they tough to rebuild? Better off getting a new one? There is some off-brand ones on ebay which look kinda scary. Whats the diff from the regular and turbo pumps? Just higher volume? Quote Link to comment Share on other sites More sharing options...
Challenger Posted February 15, 2009 Share Posted February 15, 2009 MSA sold a turbo oil pump and they just advertised more flow/higher volume. Quote Link to comment Share on other sites More sharing options...
tech9 Posted February 15, 2009 Author Share Posted February 15, 2009 Found it http://www.thezstore.com/page/TZS/PROD/SMEC07B/17-8021B Didn't think they would have it that cheap! Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted February 15, 2009 Share Posted February 15, 2009 Dang........the automatic is 4 times the price. I've been running a stock L24e (1984 maxima) oil pump after putting the turbo stuff on it and have done 50,000 miles on an engine that now has 277,000 miles with no trouble.

iaconsultants Posted February 15, 2009 Share Posted February 15, 2009 There is an old trick we used to do with the standard Z oil pump that worked out very well. You remove the fastener remove the spring place 4 small stainless steel washers behind the spring the same diameter as the spring or slightly larger (ACE Hardware has them). This increases the pressure to the oil pump of the standard oil pump above what the turbo pump has. Side note generally there are two things that go wrong with the oil pump. 1. the spring fails and it does not pump as much oil as it should. 2. The pump simply gets worn out and oil pressure drops.

HowlerMonkey Posted February 15, 2009 Share Posted February 15, 2009 Pressure is one thing but it won't combat low pressure that is the result of loose bearing clearances. A higher volume pump can help in that instance but it's best to fix the cause of they symptom (low oil pressure) rather than use a band-aid.

tech9 Posted February 15, 2009 Author Share Posted February 15, 2009 Why do you think it needs a rebuild? I've just heard a lot of people say to get a new pump rather then reuse the old one. I guess I can check tolerances on the old one and it should be OK. Quote Link to comment Share on other sites More sharing options...
woldson Posted February 16, 2009 Share Posted February 16, 2009 Those pumps are pretty dang reliable, checking it out can save a buck! Post up your findings, maby with a few picks. Quote Link to comment Share on other sites More sharing options...
josh817 Posted February 18, 2009 Share Posted February 18, 2009 I've just heard a lot of people say to get a new pump rather then reuse the old one. I guess I can check tolerances on the old one and it should be OK. You can do a clearance check on the pump and make sure everything is ok. Thats what I did on my rebuild because I knew the pump worked just months before so it should work now. Next oil change/EDIS 6 install I'm buying a new one though as I will have it off to trim my dizzy spindle. I have a Black Dragon Automtive catalog that has the turbo pumps for $50 + $7 shipping. I'll get the PN for yah when I get home if you want. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted February 22, 2009 Share Posted February 22, 2009 I'm still curious what the difference is between the standard and turbo pumps? Besides the increased pressure, does it flow more at a given rpm? Given the turbo engine has the extra oil flow to lubricate the turbo, that would make sense. But is that really the case? Another way to ask this is if it's necessary to swap to a turbo oil pump when converting a NA to turbo? Quote Link to comment Share on other sites More sharing options...
tech9 Posted February 22, 2009 Author Share Posted February 22, 2009 I've never seen anyone doing a swap say "man, i blew my engine cause of that darn oil pump" yet at least. I'm sure it flows more, and it was just precautionary. Quote Link to comment Share on other sites More sharing options...
Tony D Posted February 22, 2009 Share Posted February 22, 2009 The turbo Automatic pump had the longer gerotor assembly to compensate for the oil cooler and tubing used on that model. Elsewhere in the world, most of the turbo motors got the larger pump as they had the oil cooler assembly wether they were automatic or not. It does not have increased pressure, but flow. The Nissan Motorsports "High Pressure Spring Set" was actually from the LD pump... There are specifications somewhere, but as a rule with any pump, the longer the compression section, the more flow it provides, regardless of RPMS...it's just a matter of physics. The pumps are still readily available and cheap because of their existence on the KA series engines I believe. I know the oil pump gasket is the same on a KA and an L... I don't know of anybody NOT running a Turbo Pump. Quote Link to comment Share on other sites More sharing options...
woldson Posted February 23, 2009 Share Posted February 23, 2009 You know me;) But of course I'm still na. hehehehe. Quote Link to comment Share on other sites More sharing options...
