S13 Rb 26 Engine Problems

[c-west norway]

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.

Sounds like an air leak somewhere straight off. But airflow meter can cause similiar problems. Check its plugged in properly, or then check if its actually working properly.
