What is said on the internet the 4.8 & 5.3L engines are great engines but really shine when super or turbocharged.

The 5.3L heads are good but need mild cleanup and better valvesprings to be great.

I would like to rebuild a 5.3L for an "Relatively" inexpensive E-85Training wheel turbo engine.

Here is the plan:

9.25:1 CR forged pistons/rods but reuse the stock crank, mild turbo hyd cam, Edelbrock Victor Jr intake with 60lb injectors and an elbow with 90MM TB, a 67-76MM turbo, one turbo header & a shorty for the other side.

Am I on the right track or DEAD Wrong?

What Turbo would Ya'll use?

Stock reprogrammed ECU or Stand alone?

Any idea on cams?

Might be better in the forced inductions section

Agreed re the forced induction section but for what its worth I wouldnt bother with the edelbrock intake and elbow. Also with a small turbo like that if big numbers arent a priority the stock bottom end can support considerable boost and power levels. MP76 has been producing great results for guys lately on the cost effective side too. Stock PCM "should" be fine providing you dont run more than 12 psi through the newer e38 ECM. Anyways read this and search it out these builds have been done a gozillion times and lots of info here about it;
