2.3 PS Pump on a 2.4
Monday, March 05, 2007 7:01 PM
I was wondering if it was possible to put the 2.3's belt driven power steering pump on a 2.4l motor? I will be running an 086 head with HO cams and towers and dont really want to hastle with the hex cut if I dont have too. But if the 2.3l pump bolts to the 2.3l block I might have too.

I can't tell very well from all the pictures I've seen, but it looks like the assembly bolts directly to the block...If so, a custom bracket might be required...click

Perhaps some of the Quad 4 guys could comment, because if it is cheaper/easier, I may consider this instead of getting the ld9 lifter bores expanded.

Check Magick post in the photo and media forum. He has a few pictures of his old style pump swap. He used the 2.3 bracket to hold it.

2.3LO cam towers = 35mm + it has the hole all ready and cut out, all you would need to do is have the cam have a hex put in it.

I would sooner fabricate a bracket than screw with the cams......not because I can't do it, but because I just dont want too....PS pump swap should be much easier.

The 88-94 LO cam towers use the 35mm lifters, and old pump setup (just like the HO)

The 95 LO cam towers use the 33mm (2.4) lifters, and the new pump setup (just like the 2.4)

Sooo....... I dont get what your trying to point out?

To run the older belt drive setup on a 3rd gen, you'll have to do like Magik1109 did for his swap.



OR have a machine shop bore out the 2.4 towers to fit the 35mm lifters, which is probably the route I will take.

just make a bracket like i did, the machine shop charged me like 5$ for it. if you use a longer bolt like in the pics, you will have to cut it because its in the way of the dipstick tube. and i dont remember why i had to get the bracket sut at an angle like that... something must be in the way....

you will also need that bracket. this one bolted directly to to the block

If I were to do this, would I be looking at getting the pump with variable effort steering or w/o?

Also, would I just go to autozone or advanceautoparts and tell them the size of the belt I need? I did this when I did my underdrive pulley, but I'm asking this because I don't know how small of a belt you can get.

Nevermind, its the one without variable effort.

Sorry don't mean to jack the thread, but what if I wanted to use the 086 Head on my 2.4, and just wanted to use the Secret Cams, would there be more to the swap than just boreing out the Water Passage on the Head to match the water passage on the block?

you wont need to do anything else... just be sure your valves/pistons clearance is allright!!

I planned on using the stock HO valves, and get a custom set of 8.5:1 CR Forged Eagle Pistons from Karo. That will give me a CR in the end of 10:1 so I will need HPT to get a nice tune.
