Hi guys.
I havent talked much on here since I got my 86 S10 Crate Iron 3.4 TBI on the road... and now I would like to start gathering info and parts for a turbo system that I will be building in exactly 6 months form now.
What is the drivetrain??
-GM Crate iron 3.4
-H260-2 cam
-Bored 2 bbl TBI intake
-400 cfm Holley TBI
-2 45lb injectors
-FP = 13 psi
-Headers
-MSD ignition
-Rebuilt T5 tranny
What is planned??
-E-fan (this week)
-polish/port (flow benched)
-1.6 Roller Rockers
What I want to do 6 months form now??
**Forced air!!
**16197427 ECM with $0D 4.3 TBI tune

Now with my current research I have found out that I can run 6-7 psi on the stock crate pistons and valvetrain.
* first question... which turbo and from which vehicle will give me 6-7 psi at 5500 rpm on my iron motor??
I have instructions on how to boost fuel pressure from 13 psi to about 24 psi under boost conditions with a vacuum referenced fuel pressure regulator.
I read that I need a Bar 2 MAP sensor.
* How do I make the 7427 ECM recognize this?
I have access to a MIG welder so piping and fabing is not going to be an issue.
My motor runs 9.0:1 and I already run 91 octane just because.
* Will the timing need to be retarted at all?
*Last question for now, how many HP do you figure I will be creating at the wheels?
