Am switching over the old leaking injectors in my 1982 HR30 with the L20 turbo motor but can't seem to find the resistor pack.

There must be one as it's running low impedance injectors(2.8 ohms).

Anyone know where to look please?

Thanks!...I've read that Nissan used cheaper ECU's that needed resistor packs because they couldn't handle the low impedance injector amps.

My R30 definitely doesn't have a pack so if you are right they must have used an expensive ECU in only the R30 turbo model...interesting!

wow i haven't logged into SAU in A LONG TIME...

that pic is of your boost vac sensor (from memory)

I swapped my L20et injectors for RB20 ones ... pretty sure it was the na VL commonwhore ones @ about $80 each > maybe try searching for my old thread

good luck with those brittle old injector spacers and finding where you start sucking in air when you change them :)

Yep it's a 1982 so 30 years old so needs some work,I notice the injector spacers are already broken (havn't touched them yet) and there's petrol bubbling around the seals.

I was going to but some RB20 injectors in which are 14.5 ohm(high impedance)and by-pass the resistor pack but seeing there isn't one I guess it's back to finding some low impedance ones.

Yes that's the boost sensor in pic,was showing wild fluctuating boost on the gauge so I broke it open and cleaned it,works fine now.

Just replaced the water pump recently as the shaft had wobbled out of it bush and the fan was hitting the cowl...it ontrack.jpgdeserves to be bought back to top condition after towing a horse jogging frame every day for the last 7 years.

Oh and it can still keep pace with my R33 RB25 turbo easy,don't know how but it does!

    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
    • meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
