I use my truck as a daily driver and to tow occasionally most the time into the mountains. I haven't been towing since adding aftermarket stuff to truck due to play toy being rebuilt but it won't be long. Anyway I'll be towing around 10K usually and maybe 15K or so rarely. My question is I am hitting very high egt's when at wot. I saw it hit 1600* in 6th gear at 2800rpm messing with a Dmax on way to work last weekend . I let off quickly fearing a meltdown. I usually only hit about 1350-1400* in other gears this was my first time pushing that fast that long. I had my smarty on #6 with fuel economy timing everything else is default with waste gate set to stock. Do I have wrong setup on smarty is this normal temps with setup and do I need bigger turbo or what? Maybe an GDP intake or something similar? I'd like to end up with around 600hp in the end so I'd like to not put something on now that will be replaced/upgraded later. Thanks for any help and/or advise you can give. By the way the Dmax won

What turbo are ya running now? Not a stock turbo I hope.

REVO?

If so, be careful with the timing on 4 when you are playing...

Stock turbo still. And yes revo and I it is version 4.16A on the smarty. Is running timing 4 bad because it keeps the cylinder temps higher? I know I need a bigger turbo I guess the better question is what size is best.

I have been considering a larger turbo for some time, lots of opinions out there regarding stock replacements with better performance. I actually looked really hard at twins as well.

Some twin kits are made so you can use the stock turbo as part of them. If you look at a good aftermarket replacement, it might serve you to consider one that is a direct replacement with a little more CFM's over stock but bolts straight up with no downpipe changes. Tht way, if you decide to go twins you only have to buy the 2nd turbo and the plumbing.

I am leaning toward the D-Tech twin kit down the line. So, I purchased the D-Tech 62/65 as my replacement for the stock turbo. Then the 2nd half of the twin kit will come later if I need more to get the EGT's down more.

you could go the cheaper route and get an aftermarket intake horn, 3 piece manifold and a bigger down pipe. all would help your truck and make it look cooler under the hood.

Reduce your timing setting. You want to get the temp out of the cylinder and into the exhaust manifold. More timing will give lower egt with higher cylinder temps = melted pistons. If you want 600hp in the future get a twin setup using your stock turbo and a s475 and skip the larger single. I am loving every minute of mine and I have yet to get the temps over 1250

If I run twins now I'll have to add head studs and valve springs correct.

yotaonrocks

Are twins really needed for 600hp? I have read alot of post by madhat and he runs over 600hp according to his sig with a single. I would rather keep a single and only get 500-550 I think then spend all the money for twins now.

COUNTRYBOY

No you don't need twins, just the fuel to feed a larger turbo... Studs would be highly recommened, but valve springs are so you can run higher RPMs, not more boost...

Looks like you need a 62/65 size turbo if you have any inclination for twins down the road. It would be a good single for towing with better heat reduction and more air capacity for better cooling. It would also be a prime candidate for a quick spooling twin setup.

yotaonrocks

I don't really want to runs twins if I don't have to so what size single would I need. Is there a size that can meet all my needs? Sorry if some questions seem stupid I'm pretty mechanically inclined I do a lot of work on 4x4 rigs I am just fairly new to diesel performance and I get lost easily trying to research it through the forum when people start talking about s whatever number turbos and what not. I'm trying to learn though. My friend was right when he said the diesel itch would get me after I told him all I wanted was a mild chip. Thanks again for the help and suggestions.

Like I said, and rip 112 said, a good replacement turbofor DD/towing is a 62/65. That's what I just installed inmy truck, it really made a difference in performance, EGT's were instantly a couple hundred degrees lower and then some. LOTS of low end spool up and considerably better than the stock turbo.

And, ofcourse, if you get the twins bug down the line it is perfect there too.
