The turbo I have is a 60mm schwitzer turbo 150 ddp injectors and a hot rod vp44 I bought the truck with all of this and all have less then 6k miles I’ve driven the truck for about 1k miles and notice the turbo doesn’t spool past 8psi until about 2k rpm is this slow? Also the most the turbo has spooled too is about 25psi because it runs out of rpm and smokes really bad down low in third fourth and fifth gear 

Personally I prefer using a smaller turbo with a wastegate on a DD or towing duty truck.    The waste gate can open and bleed off excess gas at the top of the rpm range without lossing low end spooling. 

 

 

Depending on what you use the truck for I would say a 12 cm housing would be a much better choice than the 14 cm.  

 

 

What does your truck do?

My truck is used as daily driver and hauling about 3-5 cattle around 

Honestly if I was you I would opt for a he351cw.    It will flow ~450 hp, it is very tough, it is cheap, and it will spool faster than the 62 or 64 mm sxe turbos. 

 

If you want an sxe I would opt for a 62/68/12   It would flow ~ 500 hp maybe a bit more and spool faster than the 14 cm housing version.  You will loose some top end, but every post of yours so far seems more geared to lower rpm ranges.

 

 

Your injectors should be replaced first though.  You will not be able to tune out the smoke of them regardless.  They are not correctly designed for street use.   DDP uses the WRONG spray angle nozzles. 

 

remember a turbo diesel engine at or near 0 psi might as well be a NA motor,  A new turbo WILL NOT help offidle smoke.  A new turbo might help clean up smoke faster once it is lit

Should I get 6 hole or 7 hole 150hp injectors ?

 7 x .010's are generally speaking the best injectors for a DD truck.

His truck has more fuel then mine with the hot rod pump and mine lights at 1500  with 355s and 35s it's a blast to drive and keeps it cool on the highway 

and you have control over timing and injectors that aren't spraying at the wrong angle.  

 

the 14 can work, but the 12 will spool faster.    I would also argue a wastegate should be used.  having a wastegate prevents overspeeding without having to oversize the turbo to prevent overspeed.  VP trucks make power at 1800-2200 rpms, not 3k + rpms most want to size a turbo that reaches peak area in the turbo maps at this point.



regardless, for the goals of the OP a set of 7 x .010s from DAP and a HE351cw will meet his goals for less than the cost of the sxe turbo.

What about the SXE 57

Edited July 16, 20195 yr by gipperkid

supposed to be good, but Idont know that it flows significantly more than a he351cw,   You could install a 351 for ~$500 said and done.   

 

hard to recommend a more expensive turbo that preforms the same.  

 

the he351cw is a very underrated turbo for a vp truck that does towing duties and Daily duty stuff

Any idea where I can get a he351cw?

I found my Holset HX35 on eBay for pretty cheap with free shipping. Exactly what parts are needed to build an hx35/40 hybrid? Being I already have the hx35.

I have a HE351CW from an 06 Ram. The waste gate is seized on it.

That could possibly be fixed. Pull the haust housing off. Warm up the exhaust housing in an oven or with a propane torch then dump it in a small bucket of diesel fuel. Let the heat and it soaking hopefully free the shaft and wastegate up. Might take several passes and some light tapping with a plastic or rubber hammer to shock the wastegate rust.

The mechanical vgt s300 and 400s are coming yay 

Just saw that posted on FB. Very interesting. I'm sure pricey also.

S400 on my truck with that oooooooo
