Hey all, looking for input on my turbo build.
A couple weekends ago my friend and I took a 93 GMC 6.5 turbo and spend two nights welding and turning wrenches our result:



The build is successful just would like to hear other people advice on fuel management/tuning.

Best option obd2 upgrade. Some even offer universal install. Not much tuning with stock. Adjustable fuel rail upgraded injectors. Head job.

I've been planning to turbo my 2.5. Best tuning options I've found are the AEM FIC6 (I believe that's what it's called), which is a standalone ECM that you write a custom tune for, to the tune of about $1000, or you can use a Split/Second PSC1-002, which is a MAP sensor reader thing that can read boost and changes the signal so that the stock computer can read it and not freak out. You can tune that as well, which is what I plan on using since it's much cheaper than the AEM and I have no need for a rocket science standalone ECM. Or, you can go full bare bones and put a Zener diode on the MAP sensor so it doesn't freak out when boost hits and it sees more than 5V, and one of the diaghram FMU's that run on vacuum. When boost builds, it sees that and pushes more fuel to the injectors. Crude, but effective. Best of luck.
