I have a s13 with an rb26 engine. big single turbo, apexi pfc, 300zxafm, 260cams etc...

I am having a problem with the engine at the moment.

I pulled it hard in first and second gear, and all of a sudden, the engine lost power.

idling is fine, no leaks, changed the plugs to see if they where blown but with no luck.

its fine driving at low speeds aswell, but when it starts building boost at 3000-3500rpm things just bow down.

the air/fuel is going ritch, and lots of black smoke comes out...

right now im thinking there is something wrong in the ignitionsystem.

it seems like its not firing at all on load. tried to release the pedal a bit too, but the same things happens.

have anyone here had similar problems vith their rb26 engines?

its REALLY boring to drive it now....

any help is mutch apprechiated!!!!

Its very hard to try and diagnose over the internet. But I doubt it would be an ignition system problem. You have 6 coilpacks and I would think that it would be rare to lose all six at once. I would be looking at the air side of things - e.g. Air Flow Meter, BOV leaking. Have you got a gauge monitoring your boost pressure in your intake manifold? Just check it to see what may be going on.

Its possible the timing has adjusted? Could be one of many things.

check your cooler pipes. i had something similar a while ago. it would idle like there was no problem at all, but come onto boost and the cooler pipe would be pressurised and i started to leak near a clamp.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
