Hi guys, the time is coming soon for me to do a cam swap. I already know what cam, springs, retainers, and rods, but what oil pump do you guys recommend? I am starting to hear the ls6 isnt much better than the one i have now. So which ones should i be looking in to?

 

i used the melling m295, its just a small upgrade from the stocker, but really its less of a problem with 01+ than it is for the first few years. i believe you already have the ls6 in your car

there is also a great disscusion on oil pumps lower on this page

 

I have no complaints from the TSP Ported Ls6 one...

 

so i can just get mine ported? Will this suffice? I am going with a cam that is a little more on the agressive side.

 

Melling 296. Do it right the first time and don't regret it.

 

GM makes a hi volume pump # 17801830

 

And if you're not careful it will suck the pan dry at sustained high RPM. Without knowing how your engine is built and what demand the pump has on it, I'd say just go with a ported 01+ stock/LS6 pump...it's better choice than anything Melling offers.

 

I have used TSP and Melling oil pumps and both are great. On my formula, I took apart the original clean it up polished the inlet and shimmed the spring. At idle its always at 65-67psi and at wot its at 81-83. Im running 10w40 Castrol Syntec in it.

 

I love my melling!
and the Lsxtechnician left the high pressure spring in it! gotta love the added flow and pressure. I get instant pressure at cold starts, and even when the oil in hot the pressure never goes down.

 

1. That is what people on the internet have said. Is it sufficient? Probably. Is the Melling better? Well, Mine went in perfect, makes great pressure with the high pressure spring, and works great. Shop manager for TR told me they only reason that he stocks ported GM ones is for the internet crowd that has it in their heads that this is the way it is. He said Melling is far superior, and recommend it highly.

2. If you are at such a high rpm that you think a pump that is making probably 20psi more than stock will suck 6 quarts dry, you need to figure out why your oil is not returning quickly and strongly consider switching to a dry sump set up. My L98 motor made so much oil pressure that when cold at idle, it was off the crappy digital scale. After it got hot, would peg it on full throttle runs. 5 quarts, inferior design engine, and never had an issue....

 

My Melling 10296 is sitting at home waiting to go on. The 96 # is the high volume one as opposed to the OEM spec 95. Get a 96.

 

hmmm....sounds like their is alot of opinions when it comes to oil pumps. I dont want to spin the motor over 6000, maybe 6500. I am not really sure. I am getting a cam in the 230ish duration, but with alot of lift. Does this matter? I dont mind spending a buck, but if all i need to do is port mine than that seems to be ok.

 

i got mine from lingenfelter its 97 shipped, shipps in 1-2 days its a high volum and high pressure pump, has the option to put the stock pressure spring in it.

 

Melling 296. Leave the high pressure spring in.

 

TSP Ported LS6 is doing great in my car

 

Your telling me it is $97? I looked at the one on thunder racings site, i dont remember how much it was but it was alot more than that. I assume since it is from there its probably a really good pump huh? If i port mine will that suffice? I have an 01 car so i hear it has the ls6. Anyone had problems from porting their stock one? My car has logged some miles on it, so would it just be good insurance to get a new one? Do they even go out? Never heard of one going bad, just me tho

 

+1 that's what i';ll be running on my car when i swap the cam, just need to find some time.

 

I am running a ported ls6 from sdpc

 

ported or shimmed ls6

 

Just keep in mind higher volume pumps also require more HP to drive them... That said I went with the ported, shimmed TSP pump.
