hey guys,
just was wonderin one thing about the 2.3 oil swap that i cant find out for sure.... i know how to do the whole thing but i have a 2.3 oil pump out of a single over head cam "just the regular 2.3" and i was wondering....will that pump still work for the swap?? or do i have the get the 2.3 pump out the the quad 4 high output 2.3??? i hope i can use the base model 2.3 pump...but if not..i have the part # for the h.o. pump and i can hit the dealership up......any help would be greatly appreciated....thanks guys. i just need some answers quick cause its in the machine shop as we speak....thanks again guys.
there is NO sohc 2.3 quad 4. and im pretty sure u can use a base model 2.3 pump.
from the performance sticky
this is where i got my info from. ^
The pumps from all the pre-95 2.3s... the LO, the HO, AND THE SOHC are the same and will work.
But with all the work involved to do the swap, I would suggest using a new pump so you know your using non-worn parts.
sig not found
USE A NEW PUMP, you need oil, oil is very important, so dont cheap out, if you are going to do this swap, make sure it is done right, and you have a new pump.

So with the swap basicall it gives the car more oil/ pumps oil more efficiently?
Esp, with performance mods?

Remember....syringes go in the RED waste basket.
- More consistent oil pressure throughout the rpm range.
- Pressure does not drop off after 5k rpm as it does with the balance shafts
- Lightens the engine by a considerable amount
- Frees up about 10-15 HP
There may be more.

Oo, didnt know that part.
How long did it take/is it taking to do yours?

Aw man the balance shafts are like 25 pounds I swear. The 2.3L oil pump is maybe 2 pounds then with the windage tray, brace and pickup, maybe 3 pounds. A huge weight difference...less weight for the crank to turn via a chain. a lightweight gear driven pump is much, much better.
Took me about 2-3 hours to drill all the holes. another hour to plug the originals and sleeve the feed hole. Another hour to modify the windage tray and pickup brace.
The machine shop has the block now and they are making sure the sleeve is not going to leak. I believe they said they are going to remove the sleeve because they did not like that idea. They are going to thread where the sleeve inserted into the oil gallery, and o-ring the other side where it is in the block. Then slap a bunch of sealant on both ends. He said that will provide a much more pressure-tight seal than just a sleeve with sealant on it. I agreed, so they are going to do that. I can't imagine that taking them more than an hour and a half at the very most. Should not even take that long.
So total...about 6 hours.

But you had to remove the engine.
Bleh, so much for that idea.

oh yeah...no way you can do this with the engine in. Too much modifications...and whenever you drill holes in the block it should be thoroughly cleaned. So no chance of doing it in the car.
This is on my spare engine that will become the main engine this spring.

$80 something for the Melling HO oil pump from AutoZone. Three day wait.
That's funny, because on their website, it is $139.99 for the Melling M-136 oil pump.

Buying direct is always more than someone who buys in bulk.
