How does the power feel in the setup? What are you hitting on boost? Also do you think the roller rockers are helping at all in the power department? I know you put them in due to how stock ones wear but I am curious how they do performance wise as well. You also have probably the most mods on an engine running a Typ4 cam that I have seen, any plans on dynoing after it is broke in?

IDI mods, ive got a few, but in my opinion its still stock ish. i didnt fool around with compression, or polishing up the intake/exhaust runners, still running a stock turbo.

yea i have better valves, springs and roller rockers, but i didnt expect any power change from either mod, more for longevity. these engines dont spin up very fast, or very high, IMO its damn near impossible to feel the difference with roller rockers.

i have had some worn out valve guides in the past. and this is why i bought them,
less friction is always key.

right now im chasing a vibration. i think i accidentally installed a turbo flywheel,
finally got it up past 3k and i dont like it. the crank and rods are N/A
so ill pull the trans tomorrow.

the only dyno round here is ran by electronic diesel douches.
that wouldnt know how to operate a Kent Moore J33300-A

im only hitting 6 psi right now, i have no exhaust leaks, and i have not messed with the WG.
2.25" charge piping into a small 1000 cfm FMIC

but i still need to adjust the valves and timer her up.
i set it @ 7* on the stand,

I think it will be a strong running setup! You have an RD90 correct? With that much fuel, are you going to set boost high enough to clear it up? I guess what I'm asking is how much boost are you gonna run? Lol.

could i get a bigger turbo? sure.
as long as my EGT's are kept under control, thats all i really care about.

im not gonna lie, this rig will be a pavement princess.
most action itll see is pulling boats in fair weather.
and in the winter, it can see alot of snow.

i built this for my kids woman, and i to take trips up the coast, camp on the beach, and visit my parents, they live at 6000 feet so a real 4wd was a must.
and with my 26 foot and my 33 foot boat, this truck should have zero issues!

i have other trucks for off road use.

and since I brought this thread back up, heres the outcome of my build.
all torn down ready to get another short block built.

I have my spare engine in, and it runs pretty good.
still gonna rebuild, but I will most likely put that engine in my 41 1/2 ton truck
