So now I have a new issue, I have a 14b rebuilt with a 20g wheel and a stock 14b housing. I am running 450cc 2g black top injectors and a stock 1g maf with the lower honeycombs removed. So with that in mind I am running off of the wastegate. But my car is running extremely lean from the looks of the plugs, and the fact my exhaust manifold was red hot the other day. But the plugs are pure white, so I looked at them a little closer with a magnifying glass and i didn't see any signs of detonation on the plug itself. I only have a narrowband af gauge (useless I know) but this restoration has kinda zapped my funds at the moment, But the gauge is constantly in the "rich" zone. Do these narrowband gauges just take a guess at where my afr is?
I did a boost leak test at 15 psi and the only thing I could hear leaking is something under the intake manifold, so what I'm thinking is my intake manifold gasket might need to be replaced because its sucking in air pretty much directly into the combustion chamber. Am I wrong in thinking this would cause the car to run lean?
The first one in the pic looked just like the others, I touched it and it came off.
