Top end upgrades!
It’s been a long while since I’ve posted!
Recently made some purchases to freshen up the truck a little and will be installing slowly in my free time.
238/80 bitterroot diesel injectors
comp beehive valve springs
Smith bros pushrods
arp head studs
riffraff diesel stainless injector cups
and finally installed my hydra
Shooting for the 500 mark
Anything I’ve missed that I need to purchase ?

I have already replaced the cups already. I am doing studs one at a time. Working on the springs first.

A freshen up of the heads wouldn't hurt (new valves, new valve seats, ported head, but I have no clue what mods are needed to make 500hp on these engines either so theres that.

I haven’t seen you around much lately. Glad to see you still have the truck. If you have the time and $$ and are looking at the 500hp target, I would give some thought to upgrading the 38r. There have been some pretty strong updates since that turbo was really popular. If not, enjoy it as is and let us know how you like the 238s

I have my 2001 7.3 apart right now and am putting a stage 2 kc turbo in it with the same injectors you bought. I doubt I will be near 500 hp though as my tuning will be more conservative as I have PMR’s. Depending on your primary uses and gears/tire size you could use a stage 2 or 3. Stage 3 would get you to 500 easier I would imagine.

this! If it’s in the budget, a t4 kit with a borg warner sxe turbo sized appropriate to your needs seems like it would be hard to beat.

38r has stock size turbine.
There's quite a bit of exhaust from 500hp..
EGTs,EBPs through the roof and possible surge expected.
I'm running Holset HX50 86/72 turbine,16cm housing and NO intercooler.DIY 205/80 hybrids.
EGTs maxes out at 1100f in "normal" driving.
(I think that even 86/77 turbine would work in my application)
