99 FL60 mutt/conversion/repower project build

[malibu795]

Wore the rear pads off and caught a rotor :doh:
Both wore evenly

As with the theme of the truck.. mis-matched rear calipers in piston size....
Since rotors are inboard..... I put some cheap pads on,
got new rotors calipers pads, wheel seals coming.. swap everything when I get back from KS..
Front pads are 80% of new,
pads/rotors are same F/R

There's two caliper size (F) 2.6" and rear are either 2.6" or 2.8" if I can I'll put 2.8 all around..

That's my.life... nothing is easy...

Adam have you considered an AFC Live setup for the truck? will allow you to dial fueling on the go

I give you another of credit. Either you really love what you do, make alot of money at it or just down right have alot of drive! I thought for sure by now you would have gotten a new career! Keep on keeping on!

I have it along with Max travel kit... Kinda useless until I get more fuel..

Thanks.. going on 6 years
When it's going good I can do well.. especially for a single guy with no kids..

I could have sworn I warned you that the turbo you picked out was too small. I think you have more than enough displacement to drive that S400.

 

[malibu795]

You definitely mentioned you'd go with a 400 frame... Along with several others.... As which specific 400 you'd go with was never mentioned...

I have air flow
Intake valves float at 30-35#
Head lifts 35-40#

How big of a 400 do I go to reduce the risk I've overspending but small enough I'm not under it all the time. Peanut gallery is still out on that...

Only problem I have with the 362/68 is turbine wheel is too small which is bigger than the H1C I pulled off...

I errored on the small side vs big side

I took a blind shot in the dark with this setup.... Remember?

are you sure its boost pressure that lifts the head and not drive pressure? whats your current drive pressure? 9/10 times guys say boost popped a HG when really their drive pressure was double what boost was.

 

[malibu795]

The guy that I posted about having a 8.3 in a f550 blew the HG out at 35-40#.... Was his drive pressure 2-3x boost IDK...
He also said 30+ boost holds intake valves open..

I currently don't have the cash on hand to find out if those are legit statements.....
Just about every common 400 frame turbo is capable of 45+

 

[JoshH]

The 464 you posted should be a good turbo for you. You don't need a ton of flow on the compressor, but that big displacement will choke a turbine quick. I bet a 1.0 or even a 1.1 T4 housing would work well. It will definitely be a little lazier than what you have now, but once you're rolling, it should respond quickly. If you have the funds, I would probably step the turbine wheel up to an 87 though.

throw a drive pressure gauge on there now and see where you are at. if it floats valves at 30psi of boost, those gotta be SUPER low pressure springs in there. a duramax stock spring seat pressure can be shimmed up to about 75psi seat pressure till you run into coil bind issues and those hold 50-60psi boost pressure just fine.

Pacbrake makes valve springs capable of 60# of drive pressure for their 8.3 exhaust brake... Intake/exhaust are the same... Logically they should be fine up to 60# of boost... ..

Iirc OEM spec is ~100lb closed seat pressure

I too would recommend this turbo. I had one with a .9 t4 housing on my lbz. No wastegate though. If your worried about boost you may want to put a gate on it but with a 1.1 you may not need it.

them boys over there are blowing some smoke on ya

whys that?


well the 2.88" piston is too wide designed for a rotor/pad that's ~1" wider
ordered the 2.6 version which are more $$ than the 2.88......

got a 3.5" 6pt socket.

pull the damaged side off.. check everything over... clean the stuff, go to install new wheel seal... doesn't work... its .100" bigger than what I pull out... napa has what I need of course I find out 15 minute prior to them closing its.. 25 minute ride in :bang

put new rotor/pads on, reuse old seal, load tomorrow at 0700 come home swap new wheel seal and do the non damage side as well....

did try and see if I could get some stemco pro torque nuts.... but rs15-120 isn't covered....

 

[malibu795]

Well had the clutch go completely out of adjustment in one stroke in downtown Philly yesterday, T/O is shoved up against the transmission.... From what I'm told the adjustment ring pulled loose... Not a common failure but does happened
Valiar is sending me off a new one under warranty.. missed the truck yesterday.. so it goes out Monday..

Gues it's a good time to get some of the little stuff done... Finish getting brakes all the way around, spacer for the fan so I can run the air fan clutch and AC.. get electric Windows working
Turbo/pump/front leaf springs/fuel tanks/AC components, CAC/radiator
All need replaced/upgraded
Course list is always bigger than money in the bank..... Basically in project..
Be in the 50s all week nice wrenching wheather :thumb:

 

[malibu795]

Finally found my exhaust leak.. it will leak when either really cold or pulling long grades...

New stoppers on the front..

 

[malibu795]

Found these guys and access Industry supposedly new heads and not Reman
680.00 for new bare and ~1000.00 for assembled..

New Cummins 6CT 8.3L 12V cylinder head 180/088/584
Access Industries - Cummins Diesel Heads, Blocks Cranks

Idk if anyone had heard of these guys?
