im running a hx-40 compressor and wheel with a 12cm housing right now and i think my egts may be too high. im waiting on the probe for my egt gauge to check it. I have the 160hp pump with 90hp injectors, #0 plate, 181 dvs, 3k govenor springs, and a 2095 rack plug. anyone have any good advice on which way I should go for more power? also I dont know what size the compressor wheel is, if i remember right it is a 7blade wheel, did the 40s come with different sizes? Im think a 14cm exhaust housing would be the next step form here and was wondering if anyone had an extra one laying around

i was also thinking maybe a custom set of twins using my current turbo and another built using a 22cm holset exhaust housing i have

 

are you using a truw hx40 or a 35/40 hybrid. because they dont make a 12cm hx40 housing and a 14cm is pretty much impossible to find they werent regular production

 

has to be a hybrid, smallest hx40 housing is 16cm

 

they make a 14cm theyre just super rare. it was a trial thing holset did they never went into production but theres a few around

 

sounds like next to impossible!!

 

high tech turbo and gillett diesel both have the 14cm housings for like $200. as for my current turbo, i took a hx35 apart and put the exhaust fan and shaft into a hx40, so im able to use the 40 compressor but also use my stock 12cm exhaust housing, didnt cost me anything cause i found the 40 laying around the shop and i noticed better power but the boost levels stayed just aboth the same
