Ive debated on which turbo to use on my 90 cummins 5 spd, i now just picked up a really nice He351 off an 05 dodge along with the hx40 ive had for some time? I read the "turbo tryouts" and was exactly the kind of info i wanted but i wanted to hear more input from more people that have ran both or just tried one or the other! Realistically i have no set hp goals, more the better i guess!
Only thing to consider is that i have learned that my hx40 is a volvo variety which i was told and i confirmed that it has very RARE & tiny 56mm inducer and is 6 blade compressor but it is NOT a super 40 like i had hoped (12 blade turbine). It does have 16cm gated housing tho! DSM forums claim that it flows somewhere between a super40 and 8 blade hx40 and there are virtually no flow maps on these volvo 40's...soo im not sure exactly what turbo to use!? My only concern with the He351 is the small turbine being to restrictive and pushing drive pressure to high??
