Preformance Racing's website appears to be down at the moment, hopefully not permanently, but according to their R51 V8 drag strip warrior...intake manifold. $$$$ though. Try to reach out to them as they personally drag race their R51 Pathfinder with a manual transmission conversion.

Website is down but there's a recent post on Facebook

Wow You're back!!!!

PS which state are you in?

Looks like Predrag may no longer be selling the intake manifolds.

That's a bummer. I believe Predrag also has his own v8 Pathfinder facebook group that he's pretty active in. Keep an eye on facebook marketplace, once in a while I'll see a Titan owner selling his truck with a supercharger kit. Maybe you can try convincing the owner(s) to part with the supercharger kit. I'd rather go with a supercharger kit before going with just an intake manifold upgrade.

Do you happen to know what is the link for the Facebook group?

I don't, sorry. I'm not in that group. I'm sure if you message predrag directly though, he'll invite you into the group since it's a private group that he runs.

If there's one drawback to the V8 R51, it's that the rarity means minimal aftermarket support. Practically nothing available at popular shops like Z1 Offroad and the like

You can always buy this guys Titan and swap as much as you can over to your R51

There isn't too much that is that special for the V8. It's usually either parts from the Titan/Armada or the V6 truck. Some things may require some tweaking like fitting a cat-back from the Armada. The V8 may use stiffer springs and different shocks, but nothing that can't be found in the aftermarket, thanks to those guys doing steel bumpers and V8 swaps themselves. Generally the aftermarket isn't big for Nissans in general, but you lift a V8 like you lift a V6. Unsure if the rear knuckles are different. Sure the front brakes are also different/larger, but you can thank the Frontier/Xterra guys going that upgrade, which is only a caliper/pad/rotor change and also recycled parts from another vehicle, from which I can`t remember, but it`s why the left caliper is marked R and the right caliper is marked L. The master cylinder is also different, but we`re talking 1.06" vs 1.00", so really minimal difference. The only real things that are specific to the V8 is the driveshaft and rear CV axles. You can get the driveshaft, but the CV`s are only recently available from Trakmotiv, which is a questionable history on quality. OEM is no longer available.

Anyone have experience with this shop?

They have multiple listings for VK56 compatible intake manifolds.

Does anyone have experience with this JET Pwr-Flo throttle body offered by Z1 Offroad? It claims to be a direct fit (no adapter or spacer required, and no custom harness). The "power flow" clam is dubious, however the larger diameter of 77mm does compare more favorably with the 73mm diameter opening of the intake manifold, whereas the backside of the OEM TB is about 70mm.

Was noodling on the throttle body idea, and rather than risk messing with wiring harness and adapters to upgrade to a new TB, does anyone have experience boring out the factory TB? No idea how thick the metal is and what diameter (mm) could be gained.
