Oil Pan Mania!!! Ahhhh!!! Help!!!!

[PorterzSupra]

Okay heres the deal I have a 88 turbo, im putting a low milage NA-T motor in. I switched everything over to this motor intake manifold, dis everything. The oil pan is still from a NA because my turbo oil pan wouldent fit the oil pump pickup position. I am using my turbo motor mounts too. You guys told me the crossmember was the same for Turbo or NA. The oil pan wont clear, the motor mounts are lined up but the pan belly is over the crossmemeber. the NA-T im putting in was an automatic but I dont think that makes a difference? WHATS GOING ON HERE!!??? HELP!!!!! And its not like you can put the oil pan on backwards, is has a lip that sticks out on the block on one side

PS: the mounts that came on the NA motor were different

The NA motor may have come out of a cressida

Go buy a new oil pump like you should have and use the turbo oil pan like you're supposed to.

Use all the engine mounting hardware from your old engine. problem solved.

"the turbo and N/A body's /chassis are identical. the only thing that changed was the crossmember in 1989..."

[PorterzSupra]

maybe I could use the NA motor mounts.... ? What would a new pump do, according to you guys the oil pumps are all the same

 

[supra90turbo]

A new oil pump is what you're supposed to do. No crying in 4 months after you have rodknock due to oil starvation.

You're not listening. at all.

how's that bov?

I've got a JDM '87 (I think) 7MGTE in my '87 that was originally a NA.
No problems. Well actuall a JDM 7MGTE and everything else except the tranny from an '87-T.
The place that the motor came from said the oil pump was tested. But the pressure was lower than what I had on my NA. I should have replaced the oil pump when I had the chance.

i put an 89+ JDM GTE into my 86.5 chassis without a hitch.

Okay heres the deal I have a 88 turbo, im putting a low milage NA-T motor in.

ok, what year is the NA->T motor. you said it has different mounts? if the mounts are different than the ones in the pic you posted, then it's an 89+ (round fluid filled mount) motor. it wont work on your car because yours is an '88 and has the old style crossmember.

I switched everything over to this motor intake manifold, dis everything. The oil pan is still from a NA because my turbo oil pan wouldent fit the oil pump pickup position. I am using my turbo motor mounts too. You guys told me the crossmember was the same for Turbo or NA.

the crossmembers ARE the same between turbo and N/A. the only time they changed was in '89, when they changed from the square style mounts to the round fluid filled mounts. the square ones are better anyhow, aside from the fact that you MUST use them because they are the only ones that'll fit your car.

The oil pan wont clear, the motor mounts are lined up but the pan belly is over the crossmemeber. the NA-T im putting in was an automatic but I dont think that makes a difference? WHATS GOING ON HERE!!??? HELP!!!!! And its not like you can put the oil pan on backwards, is has a lip that sticks out on the block on one side.

the only way that the pan wont clear is if A) you somehow put it on backward, (which i'm not even sure is possible) or B) your NA->T motor is from a cressida, which uses a different crossmember. the exterior of the 86.5 N/A oilpan that was origionally in my car is identical to the exterior of the '89 Turbo oilpan that's now in my car, on my '89T motor. (save for the oil return line)

PS: the mounts that came on the NA motor were different

post pictures of the origional mounts to the NA->T motor. they're probably either A) 89+ style fluid filled mounts, or B) from a cressida, which might be different. i'm not sure, as i've never seen them.

cressida ahh.... so I can just get a turbo oil pickup for it and bolt the turbo pan on?

 

[PorterzSupra]

K heres the ones on my motor and the ones that it came with that I took off for shaeff BTW the pan it came with had a center oil pump position and my turbo pan has a left side

 

[JonoTurbo]

cressida ahh.... so I can just get a turbo oil pickup for it and bolt the turbo pan on?

Yep, that's what you have to do. Although I had to replace the entire cressida oil pump as well. I could not bolt the turbo oil pickup to it for some reason.

Also, those other mounts are definitely cressida/crown mounts.

P.S. If you need any help with the supra lmk, i'm from willington.

Heres the problem, they want around $300 bucks for a new oil pump, I have one off my turbo that should have about 100K on it. The oil pump uses a mechanical gears so I dont see how it would stop working. BUT my turbo motor the guage was showing 0 oil pressure for about 4 months even when I replaced the sending unit. I think it was the guage, If there was 0 oil pressure the motor would not run for 4 months however I got rod knock at the end but I think that was because of low oil due to a heavy oil leak. The oil leak and rod knock was why I got a new "low miles" motor. The oil pump I took off my turbo motor the gears are fine and when I turn it makes pressure on the output line. One more thing... when I took off the pan on my old motor there was ALOT of gold chunks, at first I thought I was rich but then it appeared to be copper? Would rod knock cause this gold looking medium sized sparkles? im gonna have to take my chances with my used oil pump unless one of your guys has lower miles pump for cheap??

 

[supra90turbo]

Compare $250 to the price of a new/rebuilt engine.

 

[IHI-RHC7]

Yeah, get an oil pump.
You can get an Aisin pump from the devil. (read www.importperformanceparts.net) for $200.

 

[PorterzSupra]

I also have to drill and tap the new thread damn...

Champion qouted me $130-140ish (don't remember, it's been too long). I just bought a new Aisin last night on Ebay for $140 shipped.

I dont understand why ppl are saying the oil pumps suddenly fail if u dont change them, what breaks? They are driven by beefy gears

Do they fall apart? No, they don't, but they do wear. With wear comes larger margins. With larger margins comes more bypass. The more bypass you have, the lower oil pressure you make which leads to rod knock (hense 0 oil pressure followed by rod knock). But use your old pump, it doesn't matter, right?

You don't change your oil pump but you slap a huge turbo on your car, eh? This is getting downright comical.

 

[PorterzSupra]

change the oil pump, why not the bearings, why not the pistons and rings, I might as well just rebuild, the point of a low miles motor is not to replace everything

good question, I would have replaced the bearings & rings too.
