Find the right section for your question and go from there be it electrical or mechanical

From my knowledge the blocks are the same. I know the efi system onto the tb42 is popular. So one would assume it's either piston/ bores are different or its all in the head???
The 4.8 is a completely different engine so yea no point with that.

any reason you want the 4.5, if your going to turbo it would it not be easier to just turbo a tb42e? they make good power and torque when you pump a little boost into them

i know for a fact that you can run the gq efi on the 4.5 and my mate has tuned a turbo 4.5 with the gq computer but i want to know what parts and bit i need to get to do it to mine eg. dizzy,tps,airflow meter, i was just hoping one of the fella here had done it before!
