Product Description
Second Gen Swap Kit – what is it? The Second Gen Swap Kit simply means that you change some parts around on your Third Gen Common Rail 5.9 (2003-2007) so that the turbo is mounted centered in the same location as it did in a Second Generation truck from 1994-2002. If you have been intimate with your Third Gen, you know that the stock charger is mounted low and under cylinders five and six. Although this location works and everything fits, it does leave some performance to be gained by changing things up a bit. The Second Gen manifold is divided, meaning the cylinders are paired, 1-3 go to one port, and 4-6 the other. This gives you better performance by matching the exhaust pulses and minimizing turbulence when opposing cylinders are firing. Additionally, by running a center mounted turbo, you will have equalized drive pressures leading to a more balanced Exhaust Gas Temperature.
The kit begins by center mounting the turbo using a divided T3 manifold from the 1998-2002 24 valve truck in conjunction with Borg Warner’s S300 SX-E and SX-R turbo line. You can choose the 3 piece ATS, or the top of the line Steed Speed. Your choice of SX-E/R turbos are teamed with AGP’s .70 (12cm) .80 A/R (14cm) non-gated or gated divided T3 turbine housing for the best spool up and airflow available in a T3 configuration. We tap the exhaust manifold for EGT and Drive Pressure monitoring, simply remove the preinstalled plugs and thread in your favorite sensors.
We include an aluminum 4” short ram air intake for the turbo combined with a huge S&B filter so every bit of air makes its way to the turbo. The exhaust exits via our 4” diameter stainless midpipe which ends in the stock location for the 04.5-07 trucks. All silicone couplers, clamps, gaskets, oil lines, and hardware is included in this kit for a simple installation. 03-04 trucks will get a new downpipe.
We offer mirror polishing on the compressor housing and ceramic coating on the manifold, turbine housing, and midpipe. The polishing is for looks and the ceramic coating is for looks and performance. Although we’ve never been able to run a measurable back to back performance test, the drop in underhood temperatures when the exhaust components are coated provides a cooler charge air which leads to denser airflow and cooler EGTs in theory.
What turbo should I choose? This becomes the million dollar question and one that keeps you up late nights losing sleep over. If you have a manual truck, we are always going to recommend the smallest turbo we offer, which would be a 61-65. If your truck is an auto, most setups we'll recommend a 62-68. I know we sound like a broken record when every recommendation ends with "62-68-14", but it's the truth. Our opinion 90% of trucks will run amazing with this kit and a 62-68, even when towing, so that's why we recommend it. Now, if you've got a stroker CP3, large injectors, and an aggressive custom tune from your favorite tuner, we can move up in sizes.
- Optional T51R Mod is where we plug and then CNC machine the inlet of the compressor housing to amplify the turbo whine and whistle. Keep in mind this modification is done after the order is placed and typically ads a week or two before the order is shipped. However, sometimes it can take longer and maybe even up to 4 weeks. If you have ordered other finishing options like ceramic or polishing, it may add additional time on top of the typical 2-3 weeks before your order ships. Because of the labor intensive work and machine time needed, there can be delays beyond what we quote. We do take special care to every order to prepare for shipping and want to make sure you get the highest quality parts and service. We are confident that the quality you receive is worth the wait. We appreciate your patience while we work.

T3 s366/73
Solid kit very good customer support if your on the fence do it. truck runs and sounds crazy

Amazing kit
Amazing kit. Installing on an older 03-04 ram requires an 04.5+ turbo back with 5" vband. This kit didn't come with the vband so I had to make my own. Warning for anyone ordering internationally, I waited over a month for it to arrive through USPS and it came in separate packages more than 2 weeks apart.

T3 2nd gen swap
Only reason for the 4 stars was when I read the description it said all hardware included but didn’t have new manifold studs or waste gate fooler but those are easy to make but other then that went together good love the sound the spool up

Big improvement over stock location with second gen manifold. Makes engine run smoother. Came with everything for entire install.
They were very helpful with any question I had.
