Which would you guys recommend regarding
a. Blow Off Valve
c. Fuel injectores [for a stock 3SFE]
d. Boost Control [computer or manually]
e. Fuel Pump
a. I like Blitz and HKS. What you choose is up to you, its a personal preference thing.
b. HKS or Tial.
I don't see a spot on your manifold for a external wastegate.
What you can do is cut a hole in the manifold and weld on the mounting flange for the wastegate to it. But good luck welding to cast iron though.
c. Not sure.
Are your stock injectors high (13.8 ohms) or low impedance (1.7 ohms)?
If your not sure about the impedance look at the injectors. Their color coded (blue, green, gray, etc..)
d. Either will work. Blitz, HKS, and Greddy make EBCs.
e. Walbro (255 lph (liters per hour)).
Did you paint or ceramic coat the turbine housing on your turbo? For your sake I hope its ceramic coated.
Do you have fittings & lines for the turbo oil feed and return? Hose couplers, piping, clamps, etc..?
