I was in the net looking for some info and I read in a page that replacing the normal oil pump of a N/A, with the pump of a Turbo would be a nice upgrade. I also read that I could use the diferential of a turbo 200sx (85-86 I think), and that will give a my car with a betteracceleration.
How can I put some photos of my car, so you can evaluate its condition; I bought it a couple of months ago. And I would like to receive some experts counsel.

 

The oil pump is a definite yes.. I think it pumps liek30% more.. As far as the diff.. I dont think 200sx came in turbo.. do you mean 87-89turbo diff?? That one is Limited Slip, but if you have a stock N/A the diff. wont help out too much.

 

where can i found it?

 

There WAS a turbo 200sx in the 80's, but I doubt the turbo would be more effective on a 6 cylinder, since it was designed for a 4 cylinder. Stick w/ the Z turbo parts.

 

The oil pump?? http://www.arizonazcar.com/oilpump.html This is where I get my stuff.. probably cause its down the street.. haha

 

The 200sx diff you speak of efrain is actually a pretty good upgrade. It was used by racers back in the day as the ratio was something like 4.110 or something like that. If you can find one and don't mind killing your gas mileage than do it. It'll make a big difference in the way your car accelerated. But heed my warning considering gas prices these days

 

4.110?? ouch.. My VW has a 4.222.. just like the Z 3500 RPM at 75MPH.. Cant wait to put in the good ol' 3.4LSD

 

What year is your car?
The later 280ZX (81-83) has a 3.9 in it already so going to a 4.11 won't kill your ga milage. It will still be a noticable amount of torque gain.

The earlier 280ZX has a 3.54 in most models. 5th gear in the transmission is not as tall due to the rear gear being higher. A 3.9 in those cars would be an ok swap and easier to find.

 

Hey I asked this a while back and they said that the turbo pump is designed for higher pressure and wouldn't work right for the N/A so now I'm confused... It will work or it won't work. I forget who it was but they said that the turbo pump in an N/a will build too much pressure and mess something up.... I was just wondering because I had the same idea until they told me no

 

A turbo oil pump is a GOOD upgrade for the n/a engine (tho not really needed unless it's built). MSA sells upgraded pumps & springs... or u can just buy a turbo pump from AutoZone. The only way it would HURT the engine, is if oil pressure somehow got extremely high... like over 100psi.

 

This is why I'm putting an NA 5 speed into my 240z with stock 3.364 R180 diff.

3.062:1 first gear and 0.745 5th gear should get pretty good gas mileage.

Add, distributor E12-80 upgrade, MSD and 2 stage vacuum advance and I'm hoping to hit near 30 mpg.

 

How can you tell if its gonna get too high and how can you avoid it using the turbo pump. The only thing my motor is gonna do is run higher than stock compression.

 

Just an FYI... the turbo & n/a block (F54) is the same. The turbo oil pump pushes more VOLUME. It has a regulating spring, to set oil pressure. I put a turbo pump on an n/a engine & it had great oil pressure & never a single prob. I know many of the people that have built high hp L28E's use the turbo pump... it's up to you.

 

Yeah Nismo's right, the turbo one only puts out higher volume (to compensate for oiling the turbo). Not more pressure. If you want more pressure than you go with the spring upgrades. If you want volume and pressure you combine them. YOU DO NOT NEED MORE PRESSURE. More volume can only help so the turbo pump is a GREAT upgrade for a performance engine that sees a lot of the top of the powerband. For a stock engine it's an unneccessary upgrade but won't do any harm. So if you happen to have a turbo oil pump laying around then go ahead and install it.

EDIT: The only time you would need more pressure is if clearances have been increased or oil passages have been enlarged to allow for more oil flow. Either of those things will cause a drop in oil pressure. Which is where the springs would come in handy. In race engines there are larger clearances so more pressure is needed to overcome this.
