How important is a upgraded oil pump Hey guys, I'll be installing a cam soon, a mild one. I have helped doing cam installs in LS1's (mostly 2002) Which I have the same with 38k on the clock. I know that the more lubrication the longer the motor may potentially last under WOT condidtions.
With a friends's LS1 that we put a cam in he didnt want to drop the pan to do the chain and oil pump, the car has 12k on the clock. Runs fine, and has 22k on it now makes 420 rwhp and is a beast.
Now to the point of the post,.... it it a "Needed" thing, or a good to have. My car will be 226/228 on a 112 LSA 580/580 lift. Has great oil PSI on Mobil clean 5000.
Please, let me know your thoughts and WHY do you beleive its needed.
Thanks!

the stock ls6 pump which i think came in the 2002 cars is just fine,that's what i have in mine.i'm not all that caught up in the (ported) pump or tr6 plugs but that is my opinion.

Now as far as someone runing the right heat range spark plugs for thier application.. Why do you have a problem with that? Do you know why someone would run a tr6 plug gapped at .045? or even a tr5?

In my LT1 car I ran a TR-6 gapped to stock when the car was over 400 flywheel hp, THe same maybe with this car.
It will get a shot of n2o, a small one to get it to the 500 mark, I have to see what it makes 1st with the cam and other supporting mods....

when I did my cam swap I reused everything including pushrods. only thing changed was the cam and springs. It had 65k at the swap and drove for another 20k miles without issues with 6700rpm rev limiter. When I sold it, it was running as good as new.

My opinion is, it comes down to how far out you can maintain the
needed oil pressure -at the journals-. The more torque, the more
"down force" trying to punch through the oil film that's supposed
to keep the metal apart; the more RPM, the more "up force" and
"down force". If you push through the film you can spin a bearing.
So anyway a high revving, high torque motor wants more pressure
at the journal. This is head-end pressure (pump) but it also can
involve other work (radiusing oil passage bends, chamfering the
bearing holes, etc.). If you expect increasing tolerances to make
more oil bleed as the motor ages, putting in a high volume oil pump
can "get in front of that". But high volume, high pressure costs
parasitic drag and can even snap a drive shaft (on old SBCs; the
LS1 drive scheme, I dunno).
Like anything else in the performance aftermarket, it's an idea
with some good points and a lot of overselling.

My new motor cost me about 10k.
I would have ridden a camel thru the desert and traded my hamster if I thought there was a better oil pump to put on it.
I think the heart of the motor is pretty important.

Its $150. It's a very important part( pumps the life fluid of the engine). It's a no brainer if you ask me. You dump how much into your motor and you can't spend and extra $150?!?
Most likely your current pump is fine and will never have an issue but if you dump say $1800 + into engine mods you dont think $150 is good insurance money spent? Seems silly to me not to do it.
I think I've got my original here if anyone wants to buy it. Only has 60k on it.
