couple questions.
1. j.b.p. 2.4L ld9 High Pressure Oil Pump or 2.3L oil pump swap? also year of oil pump? (will a 95 cavalier 2.3L oil pump work?)
2. where can i find a custom oil pan? (guy at Miller Performance doesn't get back to anybody)
3. Looken to get possy traction don't know much about what you need but i believe its only a gear? any links on its whereabouts? 97 Chevy cav z24 2.4L thanks for the help. schmitzrcing
search for the team green lsd. and as far as the oil pan, i have seen several threads about doing this your self.
did a search cant find nothing on team green lsd?
anybody) check back tomorrow thanks

Ive heard good things about th team green LSD.
p.s not to thread jack but I would also like to know more about the oil pump if its cheapr/easier to do.
i wouldent, it dosent flow the volum that the LG0/LD2 pump does, also it dosent get rid of the ballance shafts.

do the pan yourself, drop it a inch lower and weld her up.
yup, go with the 2.3l pump, like Taetsch Z24 said, the 2.4 doesn't flow the volume of the 2.3
I'd love some proof showing that the JBP Pump doesn't flow as much as the 2.3 one.... not that I'm saying the 2.3 upgrade isn't better overall as a complete system upgrade.
Given the choice on a simple build I'd definitely go with the 2.3 pump, it frees up the rotating assembly a damn decent amount... overall I feel the power gain is substantial over my setup.
I am running a custom JBP oil pump, even higher volume and flow over the modified pump Mev sells as standard. I am also running his neutralized tubular balance shafts - not much left to them but they ARE still there and therefore a hinderance on the rotating assembly. I have my reasons for running a custom pump setup... but as I said given the choice to do a nice simple build I'd put the 2.3 pump in with the windage tray to ditch the shafts and free up some nice HP.
As for the pan - I'm not surprised about your results. check the photos forum somebody just posted pics of his modified pan.
For a "posi-traction" differential... the TG LSD (found in the Transmission forum} is a definite upgrade over stock but it is far from a full LSD or 'posi traction' unit.
Good luck with your build!

im looking for somebody to do the swap for me . if you know of anybody let me know. close to Dubuque, IOWA
are those pics of the stock 2.4 compared to the 2.3 or is it the Jbod high pressure 2.4 oil pump next to the 2.3?

That is my point, that is LD9 stock vs 2.3 Stock..... and that in no way shows me any pressure or flow #'s.
Just so you know Mev cuts brand new rotors as well as works on the housing a bit... I'd love to get my hands on a 2.3 pump to lay them side by side and compare overall just like in that picture...
So yeah....

And... no it wouldn't. That's like laying 2 grinds of cam side by side and saying cam #3 that isn't even in the picture isn't as good as cam #1. Nice try, though.
That WOULD be you making an assumption though.... good luck with that one.

Chuck, I just sent you a PM.
I agree that is no way proof of flow

............ so i guess JBP finds a way to put a LARGER pump in the SMALL housing?
I was going to rant, but i know other would get mad at me.
take some measurements of your "all mighty JBP ultra high output pump" and compare.....
I’m calling there bluff, there "pump" is nothing more than a stock LD9 pump with a different presser releafe spring for higher presser, NOT volume!
its like saying a t28 flows the same CFM at 20 PSI that a T4 does at 15.
FACE IT LD0\LD2 pump is just better.
but what ever makes you sleep better at night right?

I would rant back but in essence it would be pointless, because you clearly didn't see what I wrote above. But that's alright - you can keep believing what you think without actually spending the coin to see that you're wrong. As for believing mu "All mighty blah blah blah pump" is better... where did I say that? Nowhere, in fact I recommended the 2.3 pump but said I had to go with the pump I did for other reasons I haven't mentioned. I stated that it is in fact modified and quite capable but given the choice I'd still go 2.3 - if you can find all the parts easily.
*shakes head* All I've see you do lately is make one assumption after another. You seem like an intelligent guy Chris - stop guessing and start researching. You're starting to sound like a few of the prime asshats on this forum who just make false statements and back them blindly no matter how wrong they are.
Tsk... a simple question being turned into a fight on JBO - as per usual. It's no wonder I hardly post.... all the "Correct" information flying around here could build a sh!t casle and fill the moat.

I posted that about Dec of 2005 iirc.
I REALLY would like to see the JBP oil pump setup. because there are 2 major flaws (possibly more) in the 2.4 setup.
1. Gear size, the gear on the crank is larger then the gear on the pump so for every rotation of the crank the pump is spinning either 2 or 4 times as fast. (would have to count the teeth on the gears. When you start spinning the pump to fast it causes air bubbles which is BAD!!!!
2. Rotor size. as you can see in my pictures the rotors are a LOT smaller. Meaning it WILL flow less oil volume.
If JBP can correct both of those issues then i could see how the JBP pump could be a good alternative. Not the route i would chose but, until i see a pump i would be unable to say for or against the jbp pump.
ive done the research, and get this..... JBP told me that the pump dosent flow what a LG2\LG0 does...
quite frankley i dont care. i just rather see someone get more bange for the buck.
and save a motor.
well see, after all i cant be too smart, ive only bracked raced my car for 2 years, and it has 125K on it, with the stock watter pump no less. ( but i did pop a tranny at 121K)
what the hell do i know.
