Gen 2 swap?

[TH-64]

Hello everyone! I need advice. I'm almost ready for a 2nd gen swap for my 2012. Here's what I have: Stage 2 Intake, BD intercooler, BD intake horn, GDP grid heater delete, 4 inch TBE with muffler & 5 inch tail pipe, 95 Fass Fuel plus GDP filter & Big Line kit, and RaceME Pro. I'd rather not have to buy injectors. Truck is a daily driver and 12000# fifth wheel hauler. Here's my questions: (1) Will 425 ARP's be enough? (2) What size turbo is best? (3) Would a S467 or S471 need to be waste gated?

If you never plan upgrading the injectors and since you haul a good size load, I recommend a small S400 turbo like the S464-465 variety. That will give you great power potential and still have great spool up rate. The ARP 425s will be a plenty for your build.

Thanks Ray! If I were to do injectors also, would a 467 or 471 spool up quick enough? Check out BD Diesel's new S400 kit for Cummins. Sweet... but pricey. (I can't figure out to paste a link here)

If you did injectors a 467.7 would do fine. Basically you have to look at turbo size and how they effect the power curve. A small S400 lights quick and produces torque very quickly but will loose steam as you get up in the higher rpms. The bigger S400s will light much slower but have greater top end power. There are guys making 700HP with a 464 with injectors and there are guys running a S480 with stock fuel that have a turd until the engine goes over 2500 rpms. With a daily driver and especially a tow rig, you want that turbo to light quickly and make low end power.

The BD kit is sweet and pricey. Really its geared for more a performance truck. It uses a BD manifold that has a gate port. Gates are not needed on a properly sized single turbo setup unless you are gonna spray nitrous. Compound setups do need a gate.

I have sold a couple of Terence Wilcox's (Black Market Performance) 2nd gen kits. They are what I call entry level kits. They don't have all the bells and whistles but they do the job...and priced competitively. You get a BD manifold with the choice of 464,467.7, 472, or 475 BW turbos.

There are other great vendors on this forum that sell great kits. Check them all out.

Hey Ray... if I were considering Work Stock truck pulling in the future, would a 63 mm gen 2 turbo setup work with 90 hp injectors?

Sure! The only thing I highly stress is for guys with a 6.7 to use the S400 series turbo. The S300 series is better suited on a smaller 5.9. The 463-465 will great with a small set of nozzles like the 90s. The thing with bigger nozzles/injectors is that you can always simply dial the tune back and let the injectors do the work vs using a big pulse width to make power.

Would custom tuning need to happen at the same time or could a lower setting box tune work for a while?

Lower box tuning would be just fine for a while.

Im running on the same old tunes you are with this 467.7 and bbi 1.5 injectors. Truck runs like a rocket. Yes custom tuning will be nicer but you'd be surprised how well it will run without it to.
