Time to rebuild, anyone done the same? Just looking for more information on sourcing parts and upgrades to do so.

It all depends on what you want to do with it and how much you want to spend. The VG33E is a pretty basic engine in design. Camshaft upgrades are fairly common. Some switch to VG30 cams and some pick from Stillen's choices. You can make a 3.4L out of the 3.3, but it's a fair amount of labor and expense. Fuel injectors are always a weak point on these engines, so it would make sense to have yours rebuilt or purchase a set of remanufactured fuel injectors. Rockauto.com is a great place to purchase parts due to their selection and low prices. Stick with established and reputable brands, like Fel-pro, Beck-Arnley, Gates, Bando, NGK. The quality of your rebuild is only as good as the quality of your parts.

They sell performance cams on 4x4parts with heavy duty springs.

I was looking at this cam set here, but Im worried about losing low end because I can't afford to lose ANY low end at all with open headers and intake, I've already lost enough.

What do you think about the lift duration of this cam set?

S2 billet cams..473"/266 degrees.

Provides good idle, great mid range and torque.Good on turbo or street normally aspirated engines.

Provides 15-17 Horsepower increase.

The S2's are for manual transmission only. Good for horsepower, but you'll probably lose some low end torque. The stock VG33 cams were designed for torque, sacrificing horsepower.

Does anyone have any personal reviews on the 4x4parts cams, or the Jim Wolf cams? I found a video on YouTube and it sounds good but because our trucks are pretty old now it is more difficult to find information.

I have a manual trans.
So basically you're saying the s2 cams are no good if I want to upgrade my cams for better low end? Better off with stock cams? The s2 cams will take away low end?

Thanks

DONT BUY 4x4 parts stuff. if you want to upgrade the cams, buy a jim wolfe stage 1, or find a VG30 and use the cams out of that. the Stage one is similar to the VG30 cams. also port and polish the heads, as far as injectors, I've never heard of the VG33e or er having issues with injectors. if they're working now, re use them and save the money. there fine. at most you can have them flow tested and cleaned. but its 25$ a injector.

i have a built VG33E jim wolf cam stage 1, port and polished heads and lower intake manifold all matched to the gaskets.
just needs to be put together. I'm waiting to hit 200,000 k on the body. or 100,000 on the engine thats in the truck. and the only thing left for parts that i need is the timing chain stuff. then ill put everything together, just other stuff is more important, hydro assist, exo, 3 or 4 link rear.

So the OEM VG30 cams are similar or almost just as good as the Jim Wolf? Well, heck, that's convenient I might just do that and put the extra cash towards the HD valve springs.

Well, I guess you've been lucky! I had a dead injector on my VG33ER a couple of months ago. I came across quite a few when I worked for Nissan in the late 90s and early 2000s. Nissan even released a TSB; let me introduce you to NTB01-033a:

The design of those gallery-style fuel injectors had a tendency to collect dirt around the screen, impeding operation of the injector. The cleaning did a pretty good job on most of them, but we still ran into a few at the dealer that still ended up needing to be replaced even after using the injection cleaning system.
