Need some help lq4 build
Then you need an ls1/2 adapter kit that tsp sells for new placement of the cam position and crank position sensors (I think that's all it does..)
if you are running an ls3 intake and sticking with a cable driven throttle body you need to get a device to attach the cable to. scoggin dickey has em, they're about $50. I was gonna go with the same setup, but.. I flat out can't afford it.
If you are keeping the A4/T56 in the car you will need to swap flexplate/flywheels. If you are going with an 80 you need the 6.0's flexplate.
The 408 needs the ls1 windage tray, pickup tube, and oil pan, but you probably know that already.
obv you need a tune.
You also need the correct crank pulley to line up with ls1 accessories, the truck pulley doesn't, but if you have it rebuilt already you probably know that too.
