Rb25 spark plug issue
Okay so I've looked through many different threads and can't find a straight forward answer to my problem so please don't give me the bs about starting another thread. So I can't figure out what to gap my plugs to, I have fmic full exhaust upgraded fuel pump stock Ecu stock intake etc. I was running on 10psi and every time I'd get into high boost it cut out so I figured I needed colder plugs along with regapping them, I've Gapped them several times with no luck, everytime I give it gas it won't rev past 3 grand and just falls on its face. Any helps appreciated, oh and the plugs I went with were the NGK bkr7es I believe, thanks again.

Have you boost leak tested

Definitely check for a boost/ vacuum leak. Spark plug gap on the RB25 should be .028 to prevent spark blow out. RB25 oem coil packs don't pack much of a punch.
If there are no leaks and plugs are good I would check injectors to make sure they aren't leaking. Sent from my iPhone using Tapatalk |
