38R or stock?

I have been hemming and hawing about whether or not to get a 38R or to just mod my stock turbo a little bit. I plan on going with either 160/30s or 175/80s. I have heard that a stock turbo with a WW2 will easily clean up these injectors, just looking to get some opinions from you guys.

Thanks

i would try the stock turbo first with a billet wheel from one of the vendors.

if your egts are to high get a 38r or brute66 from no limit.

im in the same boat, but if the stock turbo works fine ill stick with it.

I'm also in the same boat. I'm sure someone's got this setup already, we all would just like to know. Plus spending 1800 is a lot better then 3K+

Exactly. I don't want to spend 1300+ on a new turbo when spending a little over $500 on the one I already have will do basically the same thing.

I like the 175/80 injectors with the 38r.
I drive mine in extreme all the time and the egt are rarely over 800-900

I wouldn't mind a 38r, one of the trucks I drove when I was looking for one had it, and I loved it. But if I can get away with not spending the money or using it for something else, I would prefer that.

Who's tunes? And extreme as in 100+ hp?

Also is your egt probe in the down pipe or the header location?

Dp tunes

Extreme, I don't know how much + hp extreme equals with the 175/80 injectors

And my egt is in the exhaust manifold.

1 stockish
2 high idle
3 tow
4 economy
5 race
6 extreme

I drive around in 6

For what it's worth, when I talked to the folks at No Limits this morning, they told me that the stock turbo with a billet wheel should be fine with PIS stage 2's up to about 400 hp assuming the HPOP is producing adequate pressure and the turbo is in good shape. My understanding is that their Brute 66 is a modified stock unit with a 66mm wheel that can match/slightly exceed the 38R while still retaining the ability to be rebuilt. I'm about to head down that road too so I'd be very interested in any info you have on which is best. I think I'll try to stocker with a wheel first though...you know $$$$$ and all that...house full of kids who think they have to eat every day and don't understand that the truck has needs too

Our stock turbo's down fall is the small exhaust housing more than anything else. It causes stupid high drive pressures and ends up grenading itself.
The new wheels do help lower drive pressure some, but a "stock" turbo with 175/80's is still on borrowed time.

I say run it though, just don't expect it to last forever.
