Turbo on the stock injectors?
Yes I have stock injectors.
I was going to buy the green top 42lbs injectors. But want to ask if theres any other good injectors I can use.
For the fuel pump changing the stock one and put the 255lph walbro. Anyother fuel pump that is good also?

Everyone uses simeians dekas around here. You can get them from lime swap, if your only going to run low boost a 255 would be more than sufficient with gasoline, i would change the injectors before you pop it, there isn't room left on the factory ones to begin with.

15 psi on a stock block..........be warned, your motor is not going to last long......especially where you have been running it on stock injectors
