i have a 94 cummins with a 175 pump with stock 160 injectors(old pump went for a ). turbo is Wh1c. i wanna make more power but need some advice... i've been looking at sdx injectors and not sure to go 90hp or 140 cause its only $50 difference or even 370's from new era with proper spray pattern..i plan on gettin another turbo as well... i've been looking at a JA-S300 Performance Cummins Turbo from city diesel or a htb turbo. if i was to run those injectors what compressor size wheels should i use. i've been thinking 62mm... now i also see sdx is making there own performance delivery valves...i was wonding if anyone has used them or are they worth changing...i hardly smoke at all and i'm running no plate with 16.5 degrees of timming. i'm a diesel mechanic and have no issue changing things..just wanna know what will work best

 

well how much power do you wanna make?

 

over 300 would be nice as long as its still streetable

 

good tranny?

 

trannys done billet front to back, tripple disk the works

 

ok if you go with the 140 injectors i would get a 64mm with a 14 housing, but its all about preference, it will make the best hp while being a daily driver the 62mm would be good if you only want around 300 hp those injectors will make 300hp with a 60mm so its your preference that matters.

 

depends on how everything is set up im running 370 industrail injection injectors with a supe phat shaft 62/71/14 and made 472hp at our last dyno run with a p7100 off a 94 5speed. 17* timing 191 dvs will get the job done

 

now can you run a larger compressor wheel and still a small 12mm housing?? i just still want a fairly quick spool up

 

the 14 doesnt spool bad my last turbo i ran was a hx35/40 hybrid with a non gated 16 cm housing and i had no issues with getting it to light the phat shaft 62/65/12 will light faster but with the bigger exhaust wheel you get cooler egts. i tow quite often with my truck since i put the cummins iin the ford even being a heavier truck than the dodge im happy with how thhe 62/71/14 does
