Spiff Posted September 4 Report Share Posted September 4 On my Z24ET i ran a ka24 oil pump(the high volume one) and i logged oil pressure across the rev range. Now after that one ate a valve I run a junkyard z22 with the efi and turbo and it seems oil pressure is a consistent 1 bar lower at all rpms(14psi). Basically its around .8 bar at idle and maxing out at 3.5-3.7. 5 (50ish psi) FSM says pressure should be a minimum 3.5 at 3000 rpms so its within spec even though just barely. Just wondering would you have done anything with it or just let it be. Because I suppose I could put the ka pump in if i felt like it... Quote Link to comment
Stoffregen Motorsports Posted September 5 Report Share Posted September 5 Here in Murica, Bar means a place to drink. But seriously, if it builds pressure off idle (revved up) it's more than likely just fine. 1 Quote Link to comment
datzenmike Posted September 5 Report Share Posted September 5 If you have a KA oil pump the idle pressure should be 30 PSI or better. If significantly lower than 30 PSI idle pressure, then expect worn or excessive main and rod bearing clearance, or the turbo oil line needs a restrictor. The KA pump should easily reach maximum 50-60 PSI no matter how shot your main and rod bearings are. Quote Link to comment

Question is if I should man up and fit the KA pump or just let it be since although it's low it's stil within the factory specs albeit on the low side of the spectrum 15 hours ago, Stoffregen Motorsports said: Here in Murica, Bar means a place to drink.
