I just purchased a 2001 3500 6 speed. It is stock except for a S300 turbo, 5 inch exhaust. What fuel mods should I do to the truck. I plan on getting a smarty for the truck but with the original injection pump what lift pump should I get first and also should I upgrade to different injectors. Also what clutch kit is the best for towing. I am going to be hauling with the truck I have a 50ft 3 car wedge gooseneck trailer. It will be towing about 20,000-22,000 lbs. What would work best for what I plan to do. Any information would be helpful
Thanks

 

#1 rule with a 2nd gen 24v, put a fuel pressure gauge in it before doing anything else, i wont even drive one unless it has the gauge

 

Truck has a gauge on it already. It runs 15 psi while driving.

 

I'm a big fan of Dan at Valair clutches. I would call him and tell him exactly what you plan on doing with the truck. He won't over-sell to anyone, he'll just help you get the right clutch for your application.

As for the fuel, I have a Raptor 100 pump and it seems to be fine. Had a Fass 95 on my old truck and I liked it too.

I would start with the smarty, then if that's not enough, think about injectors/turbo. JMO

 

I'd recommend a South Bend clutch, but I've also heard good stuff about Valair. I have a South Bend "Con FE" in my 2000, but it's probably a little grabby for heavy towing. I had no problems towing about 10k lbs. a few times though. I'd see what South Bend recommends.

With the turbo you have, you're going to be happier ditching the stock injectors and going with a set of good aftermarket ones like the Mach series or DDP. I have Mach 1s in my truck, but the Mach 1.6 is very popular with the heavy towing crowd from what I understand. I think the Mach 2s are about as big as you want to go with for heavy towing, but then I don't tow heavy so I'll defer to others there.

Yes, these guys are correct. A big clutch is next because 2001 HO's LOVE injector upgrades.

HO VP-44's push more fuel pressure, hence injectors really wake them up.( The stock Dodge HO injector is actually smaller than an SO injector)

SO VP-44's trucks push more fuel volume, they really love fueling boxes.

I was SOOO disappointed after my full Banks install I considered selling my brand new '01 HO. I posted on another forum my problem and they all told me "before you sell it, change the injectors"

The next weekend my neighbor told me, "I didn't think a dually could do a burnout..."
