  1. Compound Vs Single

    Performance Discussion
    Had wastgate pressure increased when I ran it, definitely no boost leaks. Everything is back to compound setup now with the smaller td04 as the secondary.
  2. Compound Vs Single

    Performance Discussion
    I understand it is too big, when I previously ran a single I was using td04L-19t low rpm performance was great, which is expected. I just find it odd it that when used in combination with the larger atmospheric Garrett the low end performance was so much better.
  3. Compound Vs Single

    Performance Discussion
    Just to clarify, this setup is on a 2.8 4JB1T. High pressure turbo is aTD04HL-19t atmospheric is a garret GT2871R. Not a perfect match for turbos but does give a reasonably even split between turbos. The td04HL is a litttle on the big side as a single for my engine, so would expect it to be...
  4. Compound Turbo Bleed valve plumbing question

    Performance Discussion
    The picture shown is to control a twin turbo setup not compounds. Which turb are you trying to control with bleed adjustment on the compound setup?
  5. Compound Vs Single

    Performance Discussion
    Hi everybody. Had a question for the compound turbo Gurus here about compound vs single turbo performance. Had an oil seal drama on my atmospheric turbo on my compound Rodeo. I have temporarily removed the atmospheric turbo and just running the high pressure as a single. All exhaust pipework is...
  6. 4HE1-TC performance build

    Isuzu 4BD1T/2T
    it is a mechanical S4MD11 inline pump, engine is 2004 intercooled variant. I don’t know exactly what truck it came out of, but is mated to the MXA so probably derated a little for the manual box. Was easiest just to modify the passenger footwell to fit starter. Would not be a huge task to clock...
  7. 4HE1-TC performance build

    Isuzu 4BD1T/2T
    using the MXA 5r that was on the engine for the moment, will probably fit a 4L80e auto when I get serious at the drags
  8. 4HE1-TC performance build

    Isuzu 4BD1T/2T
    Did a bit more work to the chassis the last few days, shortened to suit the extra cab tub. Also a bit of bling on the rocker cover
  9. 4JB1T Compound Isuzu Rodeo

    Buildup Showcase Threads - All Engines, Vehicles
    Routing it like that made it easier to make the turbos modular. I can remove either turbo with the other one still in place. Noise is not too bad, I have a small resonator in the 3inch exhaust, get a lot of turbo noise but the engine noise is pretty quiet. Runs about 8L-100km on the highway...
  10. 4JB1T Compound Isuzu Rodeo

    Buildup Showcase Threads - All Engines, Vehicles
    The gearboxes are pretty strong, but the input shaft is the weak point. Clutch is standard diameter, cushioned ceramic with double diaphragm spring. Had a heavy duty organic, cushioned ceramic, ceramic 5 puck clutch, before that and none would hold. Have over 2000kg clamp force now so input...

  12. Isuzu 4bd1 in Trooper?

    Isuzu 4BD1T/2T
    They will fit with the right engine positioning, I was going to fit a 4BD1T into my rodeo drag Ute, until I found a 4HE1T which I am setting up at the moment. The thing that gets in the way is the deep section of the sump, if you can modify the sump to work around the crossmember there is no...
  13. Isuzu 4bd1 in Trooper?

    Isuzu 4BD1T/2T
    Can’t help with the oil squirters. I know they ran an upgraded nitrided crank on the turbo versions, and slightly lower compression ratio. They will survive fine without the squirters as long as the fueling is conservative and not pushing EGT’s
  14. 4HE1-TC performance build

    Isuzu 4BD1T/2T
    I put another thread in the builds section with some info there
  15. 4JB1T Compound Isuzu Rodeo

    Buildup Showcase Threads - All Engines, Vehicles
    Hey guys Thought I would share my compound Rodeo Isuzu 4Jb1t 2.8L Turbos: td04L-15 for high pressure Garrett gt2871r for atmospheric Running around 34psi total. Turbo sizing is not perfect, but what I had available. 12mm ve pump Cam regrind, lower compression ratio, Head porting, ceramic coating...
  16. 4HE1-TC performance build

    Isuzu 4BD1T/2T
    Hi everybody. Going through a few threads regarding the 4he1, can’t fine much information on any performance outcomes. I built up a compound 2.8L 4JB1T setup for my rodeo diesel drag Ute, but I am pretty close to maxed out with that setup at around 220hp and 500nm. Now currently squeezing a...

    Isuzu 4BD1T/2T
    G'day Rick, I have a MSA gearbox in my series 3 land rover which has been converted to a top shifter. I will be overhauling the box in the next few weeks, so can get some pictures of the shifter assembly if you like Cheers Paul
  19. Isuzu MSA gearbox data

    Transmission, Adapter, Transfercase Discussion
    G'day all I have an Isuzu 4BB1 in a series 3 land rover, which is mated to an MSA gearbox. Has anybody got any technical data for these boxes, eg. overhaul and parts manual? having difficulty finding any info on the net. I need to pull apart and inspect the box, but not too keen on doing so...
