Ok guys I am having to replace my head gasket and while I’m at it I decided to put in a new turbo..... after a ton of searching I am no further along in my quest to find the turbo I want. With all the sales going on next week I’d like to take advantage of it!!!

 

-I would like 500 ish horse power

-this is my daily driver

-I tow a 10,000lb horse trailer once every other month

-I’m running a FASS 150

-ARP Head Studs

-HX40 down pipe

-Quadzilla V2 tuning

 

 

 

I’d like to pick the right turbo so I don’t regret my decision down the rd. I am torn between a few turbo sizes...

 

-S364/68/.70SXE

-S362/65/.70SXE

-S300g (57/60/12)

 

If you guys guys had the opportunity to start fresh with a new turbo what would you purchase?

 

Hopefully you guys can help me reach a decision!!

 

for 500 hp the 62  I would also do 7 x .011's or .012's.  

 I agree with ^^^ I have 62/67/12  and 75 hp injectors, but with quad v2 I'm looking in to 150 hp injectors just not sure when, I have no leaks at injectors now and like it that way lol. Plus I'm pretty happy with what I have at the moment. But I'm sure time will come.

I run a 62 68 14 sxe and love it u got get the 12 gated for 1400

I agree with @Me78569's statement.  the 62/65/12 or 62/68/12 gated with a set of larger injectors.  The quad will tune out the smoke and still leave plenty of power.

I would stay away from the 64/68 pairing in your application.

 

I am another for the 62/65/12 gated. 

@Silverdodge I actually like the sizing of that turbo. I don’t know how I overlooked the 62/68/12... how do you like the spool up on it and when does the turbo light for you?

 

 

 

Ok I think I have narrowed it down to the two sizes below. Just not sure what size is better for my application now. I don’t want it to be too big and I don’t want to regret not going big enough....?

 

-62/65/12

-62/68/12 

 

I will be looking into injectors probably next year. 

 

 

Thanks everyone for your input!!

I've run both of those turbos.  I have slightly larger injectors than you do (by a whole half of a thou!).  Currently running the 62/68/12, and with the v2 tuning, spooling after a shift is no problem.  I can get it spooled to 10 psi by 1700 rpm with ~25-30% throttle position as a single.  

If you ask Jacob, he'll say "the SXE line isn't the end all that everyone thought it was" and "the 68mm wheel seems to limit itself to 550 hp", but, it has been a robust turbo for me that has held up to moderate abuse.  

The reason I went to the 62/68 over the 62/65 was to have a bit more top end over the 65 wheel.  Was there any gain?  The butt dyno says there was, and the boost gauge picked up 7 psi at the max.  But the butt dyno isn't necessarily reliable.  Just my experience with it.

Since you tow heavier than I do, you might consider the 65mm wheel to spool *just that* much quicker than the 68 wheel, but the Adrenaline will allow you to spool either turbo relatively easy by adjusting the CANBus percentages.    

Just my thoughts.

That's why I got a 62/67/12 in between 65 and 68   not that I know any better. Definitely more laggy than the stock hx35, but not hard to get used to.

@Dieselfuture you had Zach Bore out your HX35 right? And if you don’t mind me asking what did that run you? 

 

I’ve had a few quotes for the S362/68/12SX-E for approx $1,300 and when I asked for the S300g to be bored out it was $1,400

Yes Zach, I believe it was 800 bucks for him to build me one. They charge around 100 for a core so I kept mine. And just had him send me a turbo, less turnaround time in my case. But you're limited to 3" outlet, if I didn't like my exhaust break I would of went with 4" outlet for better flow.

I have a non gated 14 and I start to spool around 1700

Leverage of the turbine on the compressor.

@jlbayes can you expand on that comment I am a little confused?

Think of the turbine as a lever. The longer (larger diameter turbine wheel) the lever the more leverage you have on what you are trying to move.

You also have to remember that the larger the compressor side gets the more load you putting back on your lever. 

@jlbayes and @Mopar1973Man ok that all makes sense I think! The larger wheel pushes more air with less effort? 

 

So do I want more leverage as in the 68 or do I want a little less leverage with the 65? I am looking for reliability and longevity 

I already made my recommendation.

 Listen to these guys they know their stuff. 

 

Like myself I'm running a 60/60/12 (HX35/40 Hybrid) for the reason of keeping my exhaust brake. I would gladly jump up to a larger turbo if I had the funds for an inline PacBrake. Just for info value the stock HX35W is a 54/60/12...

Just remember the bigger the HP/TQ goals are the lower the longevity and reliability is going to be.

 

 

Alright gents I’m going with the 

62/65/12 gated

 

Stay tuned!!!

 

 

 

thank you everyone for your help. I am stubborn and hard headed when it comes to a large purchase like this!!

I'm kind of the same way I hate to spend large amount of money on parts I'm not certain of. I tend to come here and lean on the guys for assistance and helping me pick the right stuff. The neat part is we all learn for each other experiences and know what works and what doesn't work.
