Just bought a 38r for it as well.

160/80.

160/30 if you have the stock HPOP. If you are going to change the fuel and HPOP, then can go bigger. You're not going to like the D66. IMHO, I would keep the stock OBS turbo.

I have heard nothing but hot laggy dirty slow spooling Not happy with people that go with the d66. Ive also seen some people make it work. Good luck.

What is wrong with the D66. With 1.0 housing. Ive heard nothing but good and reason to buy.

Who did you hear that from?

A little searching here and you would've found out.

Read page 2, two guys have almost the same build as you want to do.

Just return that D66 and wait for the KC TP38R. The KC will be a little bit more but you get a 66mm ball bearing turbo instead of a journal bearing 66 turbo that most have been unhappy with. Or just run it your choice. Most find the D66 to be laggier than a stock turbo due to the extra mass and design of the D66. Or go T4 and have room to grow and lots of turbo options.

T4 i thought everyone was wanting me to spend more money this and that i promise there is a reason people say t4 because it works and imho is a much better investment.

Thanks for the info. Hard believe if they are that much of pos, beans would still sell them.

I think it really depends on what your overall plans are.... Like if you tow alot or how you drive if you care weather or not your smoking out the road going to pass someone or getting on it from a dead dig.i have only ever driven one truck with 160/100 and a d66 it is what made my mind up to spend 1200-1800 more then the d66 to go t4. i personally didn't like the d66.
Like i said depends alot on you.

Also i believe dyno proven has a verson of the d66 i believe its called the brute 66 i dont know much about it but have heard claims of some big numbers.

364.5 SXE and 160/80's

secondarychaos · Mar 23, 2016

There is no reason to stay with a stock nozzle.

160/80, but I don't see why you wouldn't do 238/100's. they're nearly the same price, you can build more on it later, and you won't have issues if you discuss your goals with your tuner.

g2outfitter · Mar 23, 2016

Same price from who. Right now in leaning towards rosewood 160/80

I'm running Rosewoods 160/80s with the stock turbo 1.0 housing w/ Barder's 360 rebuild kit and it runs good.Tranny didn't last long but now I have a BTS Trans and wish I got a hybrid injector.I almost bought diy 66 but I am waiting to t4 w/ sxe charger.with what these guys have posted in the past d66 just didn't make sense.My turbo holds it and spools good just can get little hot pulling a heavy load up long grades.If you got the extra $$$ I would get the hybrids and run the stock turbo with tunes for it.

g2outfitter · Mar 25, 2016

Sorry for my ignorance but what size are hybrids and whats difference of those.

Hybrids are A code injectors with B code plunger and barrels. They use less high pressure oil to move more fuel with the downside of a lower ratio 5:1 versus the 7:1 of an A code. The capacity is changed with stroking the plunger with machining required. Most running injectors that are larger than 200cc are running hybrids.

So it seams compared to a 160/30 or 160/80's the hybrids are more efficient. Guess anything can be tuned down. Will they run on stock fuel.
