I recently neutered my Turbo wagon. Installed high comp(9.5) pistons, mounted the MPFI heads with oil and water ports blocked off, and bolted on a Spider intake and spliced in jumpers for the TPS, CTS, and idle solenoid. Along with some other creative PCV routing using and early XT snorkus. Anyway......
It runs like ABSOLUTE GARBAGE!:-\
Symtoms: Lumpy idle, but fairly steady. acts like it is misfiring, but will rev. smooths WAAAY out above 3500 for the most part. But when you drive it, there is no Umphhh. Sputters and struggles to build RPM, gains some power and smooths out in 1st after 3500 rpm again, but will not push second.
New parts: Freshly rebuilt longblock, new Fuel injectors, Fuel filter, PCV, plug wires, cap, rotor, almost new plugs from old motor
Swapped w/known good parts, no change: identical ECU, Disty, MAF.
It has brand new rings, bearings, and completely uncracked (expert welded) heads.
I have sprayed all around the base of intake and all hoses with starter fluid and no vacuum leaks.
So my question now is, would the turbo cams really be this bad in an NA motor?
Or is it the fact that I am using a turbo ECU on a non turbo motor?
