Rb20det Cutting Out

[darkl0n]

hey all

my rb20det will rev out to 7,000 in first, then you go to second and it will cut out at around 6,000rpm then if you put it in to third, you will be lucky to rev to 5,000 before it just cut's out.

it feels like the ign and fuel just cuts out, anyone got any ideas on what the cause could be, it is a dead stock rb20det, running 10psi of boost.

Your boost gauge may not be reading the correct pressure.

You may be hitting the boost limiter.

check your earths to the box on the tappet cover and to the ground wire on the coil packs ive had the same problem the past week!

yeah it feels like the afm is reaching the max air flow and everything just cut's out, i will check the coil earths tonight, also the signal wire going to the airflow meter is not shelded, so this might be causing the issue as well.

thanks for the ideas
