hi ,, I have a 2003 with 4" exhaust, afe air intake, juice with attitude, I pull a large 5th wheel trailer and i want to put a bigger turbo, but I am worried about going too big, what sizes and brands does everyone recommend?

thanks

Kevin

 

what are your intentions for the truck? it makes a difference. are you wanting to race, tow, or just run around?

for towing I went with an industrial injection sps 62/14.

 

I liked towing or just driving with my Super B. kept my egts down and spooled well.

 

It is mostly going to be street driving and pulling my 5th wheel,, it is a jayco eagle 341 rlqs. I am probably going to be stacking my bdpp and the juice too,, i really like the bottom end that the bd gives me. by the way,, which is a super b?? (being dumb here) also I notice that there is a phat shaft 62/14 in the classifieds,, would that be a good turbo?

 

That would probably be a good turbo, however the sps 62 might be better. then depending on your budget twins would probably be the best for you application. The super b is a switzer turbo by BD.

 

my budget is a bit limited,, I am just in the middle of putting out for a new tranny, fass fuel system, and I just bought the edge. How much difference do you thing between the 12 and 14?

 

I dont really know, never had any experience with that. I would say that the 12 will spool quicker, but not have the cooling effect especially in the upper rpms. the 14 would cool better but have more lag.

 

thats what I am worried about,, of course I want the million dollar answer,, lol,,, how do you think lag will affect when pulling a heavy trailer?? I think my unit is about 12k empty

 

well do you have a six speed or auto. if a six speed then i would go with the 14 or the auto a 12

 

Morkable, send me a PM if you want to know more bout mine. No prob whatsoever out of mine. 99% satisfied with it so far. Give Twest on here a call when u do decide. Best prices around.

 

I went with the High Tech Turbo HTB2 62/12 based on their recommendation and I have not been disappointed. Nice daily driver manners with good giddy up and go under a load. The stocker on the 03 HO is ?/9 if that helps any.

when it gets hot outside
or
driving on two lane roads at 60 mph
towing heavy , you will wish you had a 12

over 65 life is good with a 14

 

if you get a 62/14, there is the option of getting a super. the difference is the standard 62/14 is just that. the super gives you the chance to send it back and they will machine the compressor housing, change the wheel, and make it a 66. so it can grow with your mods.

 

No experience with this turbo but I tried a 14 housing on my 95. It is at approx the same power level as a stock 600. It was a miserable ride. Belched black all the time and took forever to spool! The 12 is definatly the way to go for a daily driver. I tried pulling a car for my neighbor. probably a 5k load including trailer and still wasnt spooling well. Switched to the stock 12 housing and love it.
If you up the turbo give us an update. I need to upgrade my 600s because of towing EGTs but I need a bolt on because of the exhaust brake.

 

the sps 62 has slightly more lag than the ps 62 due to the bigger turbine wheel

lag is bad when towing heavy or in higher altitudes
