What spark plugs and gap are you running in your rb25 and what gap?
Anything over half throttle I seem to be having blowout. If I peddle it and keep it at half throttle it spools fine. But if I mash the gass it bogs

NGK BKR6E stock #6962 gapped to .028 is what you should be running with stock turbo.

I just got the bkr7es will these work at a bigger gap?

They will work, I think they are standard electrode. If you are blowing spark, you should close the gap lower. I wouldn't gap any higher than .030

It sounds more like a coil pack issue. Not saying its not the plugs. My rb did the same exact thing. I bought plugs, turned out to be the coils

+1 on this. Went through 2 sets of coils gave up and got some ls7 coils. Easy to wire and got rid of the infamous cyl6 rb25 misfire. As for the plugs i use oem rb25 ngk pfr5g-11. My buddy at the nissan dealer found the oem plugs for me all the other ones gave me issues. And they come pre gaped.

Yea I guess the coils will be next. When I pulled them they looked fresh though. ( no arc marks or anything). But I guess you never know
