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.

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.

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.
