rebuild or twins???

[DFairhurst]

Was checking everthing over before the big weekend and as i was checking the tire pressure looked inside the fender well an ther it was turbo leaking out of the back halfguess I've been mean to her one too many times

Anyway its one of the first 64/14 htt turbos with about 60k on it and Ihave been thinking about sending it in an getting it up dated with the ss housing an changing the wheels i think when i talked to them the recomended 64/13??? not sure the said it would be quicker spool up but still run as good on the top for $750 +shipping.

I guess what Im wondering is should I rebuild it and save a few buck or buck up and go with twins? It doesnt get too hot with this turbo but would like quicker spool up but is it really worth the money "twins??" has anyone ran this turbo then went with the ss 64/13? pros cons just looking for feed back of someone thats tryed them or gone from 64/14 to twins.

Sorry about the spelling not much of a computer person on lets see if i can link the picture

With your mods, I would stick with a single. Twins will take longer to spool. I haven't run the 64/14 to compare it with the 64/13, and mine is in a twin setup, anyway, so I can't really help, there. I will say it should spool quicker, and should cool a little better, since it also has a bigger wastegate.

With your Smarty and injectors, you can support twins, but you'll need studs. If $ was no concern, go twins, but I would probably still recommend the 64/13. Probably a direct swap, cheaper, and easier.
My $. 02, there it is...

When my stock holset was on it's way out, I decided to go to somthing a little closer to it's range and went with a 62/65/12. I was wrestling with the single vrs twins just like you are and wanted to have an aftermarket turbo that would easily work well with another turbo in a twins setup.



I have a friend with a set of the Auroras, drove his truck, he has a 64, to me it seemed a bit laggy, and since I tow, I wanted to be sure to not have the lag. Another friend had a 62 setup, it was clearly a little snappier than the 64, so that is what made me go the 62/475 route. Since both trucks were standards like I have, I had the opportunity to see them/drive what was similar to my truck for my decision making.



If you are strictly looking to build a power street type truck and push your boost into high places, then studs are a must. I tow a lot, I was seeking lower EGT's and a little more power overall. I have my twins set in the low 40's boost-wise, I am seeing a good exhaust pressure ratio, well within the parameters of the stock studs, so I did not install studs. I probably will install them when I add a little larger injector to my setup, I am not going to go over 90's as far as injectors, considering 50's/60's as our trucks are a little adverse to adding too big of a set of injectors. Right now my twins are performing just fine with stock injectors and the stock fuel system.



I am glad I decided to go to the twins, and I am glad I decided to go with the 62 over a 64. I think it is all about individual driving style/use/intention of use that motivates the choice differences. If you have a plan for what you want, then follow your needs. All of those who manufacture twins setups would be glad to discuss all this with you and make recommendations, try giving them all a call and get the advice from the builders too. As I user, all I really reference to you is about my needs and the fulfillment of my needs, question your needs, takl to those who build them, they will help you to define your needs better, that's what I did, and after all those discussions all the suggestions led me to the right conclusions for my needs.

Money is kind of an issue not like I was saving for this or have money jus laying around to go an buy twins but I have learned buck up and buy what you want the first time or you will pay or it in the long run... been down that road a few times. i know i need studs that and water meth an i was going to be done with it all. .

Is twins worth the money??? I dont plan on drag racing it sometimes I will open her up but mainly a drive her to work an pull the camp trailer in the summer. so im not looking for more power or to make a sled puller just quicker spool and maybe a little lower egt's

Also I dnt knw how long its been leaking i dont assume not too long but not sure... should I park it tell i get it fixed or can I drive it? dont want to make a bigger mess. Im going to pull the intake off an check for excessive play in the wheel

It's really hard to tell from the picture... but it looks like the turbo drain line is not correctly attached. If there is any restriction what-so-ever in the drain tube, it will back up oil into the turbo and force it out the thrust bushings.



Like I said, hard to tell from a picture, but I would make sure that is not the problem, your turbo may be just fine.

 

[DFairhurst]

Huh? Dnt knw that but I will check. Its been on the truck for about 60k and never leaked. It is coming from between the main body an the exhaust housing then dripping down on the drain tube. I though at first it was the drain tube leaking but then saw it further up. But thanks for the info will definitely look at it when I remove the turbo tomorrow.

Come to think of it, I had a turbo go out on one of our Cat motors. It had an oil leak in the same area you have, but had that leak for several months. One day, there was a sound like an ambulance siren behind me, so I pulled over to let it pass, but no ambulance. Accelerated again, and heard the same thing. Babied it to my shop and found fresh oil coming from the same area that had a slight leak before. Checked for play in the turbo shaft and could wiggle it about 1/8". Turns out the bearing went out and the turbine started hitting the inside of the housing. That was the ambulance sound!

So, I would keep a close eye on this problem. It's possible that you may have the beginnings of a turbo on it's way out. Hopefully it's something minor, instead!
I would clean the area with brake clean and try to find out exactly where the leak is coming from, though.
Good luck.

Still have your stock turbo? Throw it on with an S475... spoolup is quick; almost feels quicker than the stocker alone. And the setup will easily support 600, and 700+ is common, although at those levels drive pressure is an issue. But, spoolup is just as quick as stock...

 

[DFairhurst]

I dont have the stock turbo had it sitting in the garage for 3 years an gave it to a buddy building a 12v in a ford.

Pretty sure im going to send the turbo off an get it updated from htt an do the ss housing and 64/13 got looking at prices of twins an thats more then i want to spend right now just to need to put head studs in right away.

Pretty sure turbos on its way out lots of play in the wheel glade i seen the oil leak before BOOM. ive gotten my moneys worth out of that turbo i have been nothing but mean to it and amazed it lasted along with the head gasket.

Going to pull it tomorrow an nda it to htt on tues an let u knw how the new one wrks on fri or sat

 

[DFairhurst]

Pulled the turbo off and put a stock one on so I could send it off. There was a lot of wheel play not hitting the housing but left an right an in an out. Called htt and they said in and out is not a good thing so I talked to them about it and am going w/ the ss64/13 so I'm hoping sometime next week ill have it back on and see if there is better spool. Man the stocker spools up fast but falls off just as fast then build heat... . I'll keep you guys up dated and let you know how I like the new turbo.

 

[DFairhurst]

So htt called me yesterday an in a nut shell said it would be cheaper to buy new then fix an up date mine.
I knew I had a lot of drive pressure an was over working the turbo but didn't think that bad. He said the only thing good on it was the intake turbine housing an I wanted to change that to the ss one. He said the bearings were wasted an the exhaust wheel had warn in the exhaust housing an the shaft needed to be replaces an so on
Anyway guess I'm in the maket for a new turbo haven't look in a while to know what's out there so any ideas? With the injectors an boxes turned up most of the time it is about 125-150 hp over stock I do some pulling usually around 5-6k at most. I would like quicker spool than the 64/14 but still have good flow on the top end also. thanks for any ideas

Well I would look at the Htt 62/71/13ss or the Htt 64/71/13ss and maybe the 66/71/13ss. Was your turbo a 64/65/14?

 

[DFairhurst]

Ah I think it was just a 64/14 it was one of there first ones I bought it in earlier 06 it as not a ss or low pressure like the new ones that's why I was going to up date it.
I haven't looked @ turbos in a while an dnt wrk @ a shop anymore so kinda wondering if there is better brands or what other people like.
