Hi All,

i have just completed my rebuild of my RB26 engine, spec are below

the tuner told me that i can't higher the boost due to the injector has already max at 85% or more. if we would to push 1.5 to 1.6 bar the air fuel will lean down. i have attached the dyno sheet.

The question is that i see some of the forumer here have smaller or similar size of injector but could push a much higher WHP.

Is there any problem with my setting or tuning?

RaceTech 86.5 mm piston

TOMEI 1.5mm @ 87mm metal head gasket with oil restrictor

Jun Oil Pump

Balance crank, piston, rod, clutch, main pulley

Refresh Standard Head

HKS step 1 IN/EX 264 cam

Jun Cam gear

BC valve spring

Greddy type 6 throttle intake manifold

SARD 720cc injector

HKS type fuel rail

Tomei Fuel regulator

Garrett GT35R AR1.06 split type

aftermarket ex manifold split type

Tial 44mm ex wastegate

Power FC D Jetro

ETC ETC...

Would have thought 720cc capable of quite a bit more power. Pressure on idle is fine but Walbros flow chart shows flow drops off sharply when pressure goes up so I imagine having two of them won't change that. I guess adding an external Bosch 044 or two with a surge tank would solve the problem.-

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
