It's an off brand delta core. I chose delta core because I've seen many reviews and tests that have proven them much more efficient than flat plate.

My exhaust after the turbo is an inch bigger than the turbo outlet and it's only about 6' long. I am using a Magnaflow straight through 4" In & Out. The turbo wasn't small if I wanted to keep it under 4500 RPM's. It's the smallest turbo that I would recommend for a 5.3. The exhaust side was choking it. Now the truck is a different animal but I'm still keeping the boost around 6 PSI to keep it at 500 WHP to keep my trans from slipping.

Thank you. It's a fun truck for sure. It tows very well too. Fortunately for me, my truck stays on the road or trails. I don't do any mudding with this truck. I wouldn't do a rear mount turbo if I was using this truck to go into the mud unless I snorkeled the intake up into the rear fender or even better, put the intake through the bed under a bed cover. As for the piping and everything else, if you have never dented your driveshaft or your frame, you won't touch the turbo setup. It is tucked high and out of the way. It really depends what you want to use the truck for. One build will always have its pros and cons. The debate for turbo vs supercharger also depends on what you plan on using the truck for. I prefer turbo over supercharger any day. The benefit of supercharger is the ability to have boost at any RPM. This is also a con. Having more torque at lower RPM's is harder on engines. Supercharger consume alot of HP to make HP. Therefore, Superchargers will also get worse MPG. With turbo, you are using energy that your engine is already producing. Turbo's need higher RPM's to spool up. Once the turbo is spooled, it remains spooled until you let off the throttle. If you're driving on the road at 40 mph and floor it, it may take about a second to spool back up. Even with a rear mount 78/75, I am fully spooled at 3500 RPM. I would only supercharge for ease of installation or all out drag racing.

What post?

Thanks! Oh wow, I'm sorry to hear that. Sounds like my lifter situation. I went ahead and did a full rebuild as well. The ARP bolts and studs aren't cheap. Spent over $1500 on bolts and studs from ARP. Bought every bolt they offered. That's right. You'll have a built engine ready for alot of power. The cam works flawlessly. I was worried about it with boost as well but it really helped spooling the smaller turbo that I had. Now that it's a bigger turbo, it spools a tad slower but I prefer it to not boost at lower RPM's. With the TSP stage 2 cam with the bigger turbo , I begin spooling around 3000 RPM's. I am fully spooled by around 3500 RPM's.

I don't plan on doing transmission work for now so I am keeping it in its safe limits around 500 WHP. I plan on keeping the 6L80 for now. Other than the huge cooler, external filter and the lower temperature thermostat, I'm going to leave it alone for about a year or so.

With the VS Racing Billet 75/65 turbo, it made 505 WHP at only 7 PSI. The graph showed how restrictive the turbo was in the higher RPM's due to the smaller turbine so I swapped the turbo out for a On3 Billet 78/75. I plan on putting the truck on the dyno again this weekend.

Turbo setup is done for the most part... few things in the tune need dialed in. Completed the 4" stainless exhaust with 2 mufflers and 1 resonator, all coming to a 5" tip. I wanted her quiet and it surprised me how quiet it is!

2 Breather tanks and 1 catch can setup. May seem overkill but it beats not being good enough! 1/2" hose to each valve cover. 1/2" hose to 2019+ oil fill tube w/ an10 180 fitting. 3/8" hose to gutted PCV valve tapped with a 1/4" npt 1/2" barb.

Fitment of the 4" piping was pretty tight but the spare tire still fits just like factory. I kept the drain simple by making it gravity like any front mount turbo. Can't go wrong there. No need for check valves or 2 pumps.

Just about done with turbo. My divorced oiling system is complete, purged and tested with constant 40 psi. Ran out of titanium wrap and had a extra spool of fiberglass wrap for the muffler. Figured why not.. Now I just have to coat it all with the black silicone coating once it dries to help protect it. I just have a couple more welds to finish the other half of my 4" piping from the turbo back to the 5" tip and pipe my wategate back into the exhaust after the turbo. Then weld my MAF & wideband bungs. Then back to the dyno.

Relocated ECU onto secondary battery to allow room for intercooler piping to the turbo.

Shouldn't have anymore worries on the dyno. Now I can do a pull all the up in the RPM's.

Onto the turbo portion. Here's where it gets really fun... Many hate on rear mounted turbos but hey to each their own. I prefer to have the heat out of the engine bay and no clutter in case I need to work on something. A few random parts.

Made the Y pipe from stainless steel 45 degree mandrel bends. Heavily titanium wrapped and coated to retain the heat.
