    1HD FTE (pre heater / EGR valve)

    Rob, in case you weren't aware, the pre-2003 cars battery setup is different to the post-2002's. So don't just take the conversation here as gospel. Also, I think the early cars used vacuum for something other than the EGR so check that before deleting everything.

    I guess if you are chasing power, deletion of the butterfly would also be on the list. But that's risky........

    1HD FTE (pre heater / EGR valve)

    Nice work! I don't suppose you've had a chance to run back to back dyno figures of before and after? Like I said above, I didn't notice any significant power change after removing my EGR, gutting the heater block, and cleaning the inlet path (and it was filthy). But my turbo, IC, exhaust...

    I'm not a fan of catch cans on the 1HD-xxx. Too much risk of backpressure, as your mechanic alluded to, and I just don't think a little oil through the inlet tract is a bad thing .... as long as the SOOT from the EGR is avoided (EGR delete). Catch cans add potential fail points for no benefit...

    Sorry, Yes, the batteries are wired in parallel so act as one bigger power reservoir. The only thing physically connected to the RH battery though is the heater. Notwithstanding aftermarket additions. In other words, with the heater deleted, you can isolate the RH battery with no further loss...

    BTW, the inlet heater on the HDJ is not to aide in starting, it's solely an emissions reduction device to reduce cold engine emissions.

    Note retention and orientation of the vac piping and filter feeding the boost sensor. In this pic the filter is immediately left of the EGR valve replacement casting on the crossover manifold and held with a spring clip. It needs to sit upright so excess oil drains back into the manifold:

    Two valves/sensors retained: Not shown is the small vac line which runs from the blue valve down to the hard line through the tappet cover, and then on to the top of the small white plastic filter on the front of the crossover manifold. Another line runs from the bottom of the filter into the...

    1HD FTE (pre heater / EGR valve)

    For the EGR valve, I replaced it with genuine Toyota part 17861-17030 sourced from my local Toyota dealer. I used new gaskets however they are all metal shims and could be re-used with a coat of gasket sealer. The EGR pipe was removed and I made up a blank for the exhaust manifold. The two...

    1HD FTE (pre heater / EGR valve)

    I recently carried out a 'complete' EGR and intake heater delete on my Aussie-spec 2003 HDJ100 in conjunction with reconditioned injectors, new injector lines, full valve clearance reset and a thorough cleanout of the inlet path. I did a detailed thread on LCOOL but that site is temporarily...
