Starion Oil Pumps....Decipher This Photo

I'm in the process of a turbo longblock swap in my Raider and planning the oil pan/pickup changeover right now. I keep finding this oddball cross section of an early Starion engine showing an oil pickup mounted to the block (like a truck) but fitting the turbo oil pan. I've NEVER seen this in 50+ engines I've handled through the years (they all have the pump mounted pickup) but low and behold Bad2Rass has a block mounted pickup tube that fits in a turbo oil pan. Was there an early Starion that used this block mounted oil pickup???

 

Here's a comparison from the forums.....Starion on top, Montero on bottom supposedly.

I think you're right....had my father cross reference everything at his NAPA and he shows an early oil pump till 2/83 with no provision for a pickup tube but then from 2/83 to 89 they show the same number for the standard pump.....weird.

Interesting. Is it just me, or does that first engine seem to have a gnarly crack in the oil pan? lol

 

Looks like that pick up tube set up is for the early model G54's. That pick up tube location is on all g54's I've seen, the provisions for it that is.

jon, this is pretty much the same problem i ran into with my old 4 x 4 mm. i swapped in a regular truck motor that was from a 2wd and when i tried to set it down realized there was a difference in the oil pans and crossmembers. the motor i was swapping in had an oil pan like that of the starion. pretty sure it wasnt a turbo oil pan but i dont know what it originally came from. the motor needed a oil pan like whatever came from your montero but my truck had previously been a g63b truck so swapping the oil pans was not a possibility without going out and hunting one. looking at it pretty closely i only needed like 1.5" to clear, so i built new motor mounts and lifted the motor which actually worked super easy since the truck had a body lift and the lift of the motor actually corrected the fan to radiator distance. since its 4 wd its off the ground plenty and the trucks are much more open it was a breeze to get to the motor mounts to mock them up and then pull them out and weld them up. might be a viable option for you especially if you plan to lift it.

Depends if its 4x4 or not. Its just a pickup tube, as long as its in the sump it doesn't matter.

Here's a 4x4 B2600

If you want to build a motor to rev high and not just have the pump spinning like mad and pumping it back through the relief valve into the sump and making it all full of air, this is the setup you need. You can find that at some tractor store, its the pump for the forklift/exported engines that were running in heavy trucks and buses. The "turbo" pump flows way too much anyway and all it does it dump it back in the pan when its cold or rev'd up while driving and why have a pump that does that? You ever seen the pre83 "non turbo" pump? Its just a case that use gears that are a little shorter and you can't buy it anyway, the replacement for it is the same as the "turbo" pump it just sucks from a different hole. They put that pump on there so they could try to feed those balance shafts and not have it knock when cold after they put the additional demand of the turbo on so if you take the BS out then why do you have the pump that flows too much? Even then they still had to add that rubber stick in the plunget spring to take up the space so the pressure would reach the rod bearings before it started to knock on start up but oh still people use thick oil and think it reaches those poor bearings. You have no use for all that oil. it makes for pressures way to damn high at high rpms.

What comments would you add when they claim that the noise at start up doesn't mean anything? LOL

The oil pan on the Starions is the same as 2wd trucks, both front sump, but the turbo models switched the dipstick to the other side and added an oil drain for the catch can. Like others stated, in late 83 they switched the turbo engines to a front pick up instead of a block pick up... just make sure you use the right oil pump gasket.

 

Metric posted the engine block series numbers so you can narrow down what year your block is if you wanted.
