I love my super hx40 lower egts and pulls great sounds cool too

181s are all the more you needfor a street truck. Pure diesel power sells upgrade kits for the hx35 much cheaper than to by a new turbo.

thanks for the help so it sond like getting 4gsk would be next and it should be fine without valve springs

What trans do you have and what if anything is done to it.....

its a auto 47re and has a bd valve body and a 350hp towing converter that the tranny guy recommended and ddp likes but cant remember what it is and it has deep magtec pan with amsoil in it then heavyduty bands and clutches
