Default Stock Turbo over 62?

wanting to lower egts a bit and really am just looking for something new for the truck. I recently did a second gen swap and am running my sig- I have my stock turbo sitting in the garage. Would it be stupid to compound and put stock over the top of the 62/68/.91? For the price of a nice intercooler looks like I can buy piping needed

There would be no point to do that. Why not just add an S475, also how high are your EGTs getting?

Yea that's what I figured- I have my stocker sitting in the garage collecting dust. Driving empty locked in OD cruising the hill country 1000-1250 while I'm empty. It seems too hot for being empty. However That is the perfect storm with my tight converter and low rpm/low boost and I don't tow often. I have a Spearco intercooler I can pop in but was thinking for about the same money (not buying turbo) I could do compounds.

Intecooler i dont think would help too much. In that scenario as I am only about 25-40% throttle depending on hills.

The truck is fun to drive and has a lot of power with just a little smoke down low which is why I don't really want to mess with my tuning

I don't think you're running too warm and an CAC won't really make a difference. These engines can run at 1500* all day long, that's what they were tested at. I personal like it when my EGTs get over the 1000* mark and try to hold it there all long as possible. These engines were made to work and when you work them getting the EGTs over 1000*, it helps clean out the cylinders burning off carbon. I would talk to your tuner or try running a different tune if you want lower EGTs. But until you tow and see how hot they get, i wouldn't worry about it.

thanks for the input- guess I'll just look to do springs and studs for my next upgrades!

It's a good idea to get push rods with valve springs so you don't have to worry about rod deflection.
