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.

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
