To elaborate on the components more:
-The TPS, it's an off-the-shelf GM part.

-The FFE trigger wheel sensor is a readily available part from any auto parts store as well. .

-(Mentioned earlier) "a custom LS1 coil-on-plug setup" is really just coils with short wire leads to the plugs, I got rid of the COP adapters.


-Like already mentioned, the injectors are Bosch and to my knowledge widely used. .


All parts mentioned are compatible with the SprintRE, I did my best to make sure of that.

The only roadblock I hit along the way when it came to compatibility was the idle air control. . My TB accepts a GM stepper motor design and a SprintRE will only control a two wire design. I knew this up front but it wasn't until recently that I got the idea to modify an OE 2nd gen BAC to use on my TB.
