Im new to the forums and i have a 96 6.5l turbo diesel gmc, its got a front mount intercooler and i turned up the boost but i would still like to get abit more power from it, i just want to know if a Holset hx35w turbo would be much of an upgrade for my motor? im going to get the marine injectors, what else do you guys reccommend getting for some decent power?
right now your truck is making 7-9 PSI max with your stock turbo. check the specs on both turbos and compare the size. if the HX-35 has a similar size it should spool quick enough as stock but make more boost. 15-16 PSI MAX with head studs and heavy duty gaskets is what i would do
Check my signature for all my mods. I hit 20psi with a mechanical wastegate on my stock turbo then turned it down to 13 max boost. I am going to rebuild my engine soon and do head studs with oversized gasket and 18:1 compression ratio, along with some other goodies :-)!!!
As far as the holset turbo goes, you ought to make more boost but whether or not it is efficiently, that would require one to look at some Turbo Pressure Maps.
