Also, what turbos were you looking at for replacement? These are just the ones I've looked at. I'm sure there is tons more that would fit the bill...

 

Honestly I would not upgrade my turbo with my current setup. the turbo is not the "weakest" point. All of the other things you listed are. If I had everything done and wondered if my turbo was holding me back I would talk to a pro and the people that already did what I am working on doing before making any purchase.

For me personally, I think I'm going to trade in my ecsb 5.3 on a newer (6L80E) CC 6.2 and then toss a 76mm on it. If I cant find a 6.2 then ill settle with the 5.3 again. I'm not looking to break any records but a reliable 500 wheel in a truck.

 

I feel the same way. I'm not looking for a track build but I would like to have a very stout street truck. I know that eventually everything I listed is getting done. But I guess I'm just thinking that doing the easier option first would be, well... Easier lol

 

do a before and after dyno runs w the triple 12 cam please

 

None of the BW S400's will bolt in as all the T4's have a 4" vband and sit 1/2" higher on the pedestal. So you will need a new down pipe with any of those. Any of the PTE will bolt in, but your WG, if it ties into the down pipe will have a tough time lining up as the .68 a/r housing has a 1/4 shorter Vband discharge. As for what will make the power you want, all of them will.

 

That's the info we needed. Thanks. Sounds like there isn't to many direct swap turbos.

Guys how the mp70 compared to the mp76 size wise?

 

Foot print wise, its the same size. The compressor housing is a little larger, but still a 2.5" discharge.

 

Bingo. That could be the upgraded for you then. Easy and bigger turbo. You could go w the water ball bearing version too.

 

My wg is vented to atmosphere. But the pte turbos will work with my dp? Just making sure I'm reading your post right. It seems like the bw's will be more work to make fit. So it looks like for what I want those are out. But if I can find a mpt76 that would work as well?
