I dropped a junkyard LM7 and a TDP stage 2 t56 in my Colorado last fall, and now I'm looking into a turbo for it.

My buddy has a Turbonetics Tc78 that I'd like to pick up, so I started digging around, reading build threads and so on.

So, here's what I was thinking, and where I'd like advice.

LS6 springs/cam
LS9 headgaskets
truck manifolds
pushrods
ARP head studs

Fuel is also where I'm not sure. I was thinking 42lb injectors and swapping out my stuck Colorado fuel pump for a walbro 255.

Find an ls6 intake or keep stock truck intake?
Right now I'm on a speed density tune, no maf. Should I go maf?

Looking to push 10psi or so, nothing too crazy, at least to start off with.

Thanks

PS
Here's turd truck in all it's glory. I rescued it after 8 years as a work truck.


Here's what I have to play with. It's dirty, I haven't washed it and didn't wash it before the motor went in but that's what the plan is for this winter.

i would skip the head gaskets and head studs unless you plan on going high boost 18+psi.

also, skip the ls6 springs and throw some better springs.

^^^^ what he said!

Also, I would recommend ATLEAST 60lb injectors and maybe a Aeromotive 340 pump for room to grow later!

Either intake manifold will work fine for your goals!

The stock rods will bend long before the factory head bolts stretch to the point of lifting the heads so I would think you would be better off spending that $ towards a better set of valve springs and larger fuel system. I would stay on the speed density tune.
