Thing about a twin turbo

[Doc]

That’s thinking,
Stock turbo bottom end turbonetix top end..
any Ideas?

Doc,are you just going to race this or is it a daily driver also?

Why not just big turbo? It would be way easier... It sounds like you're thinking about sequential turbos. Hmmm.

Both.. but this truck is not my daily driver..

Because a bigger turbo will not spool up as fast as the stock turbo..sequential, yes..

The ranger turbo is small, but is kind of torquey and fun to drive. Would be fun to put a bigger turbo on, some injectors and a moon tune... ?

I would think the hardest part is going to be adapting the electronic controlled waste gate to function the way it needs to for bringing on the atmospheric, while maintaining a healthy and durable drive pressure.
main points that I would dig into-
-what are running out of first right now, fuel or air?
-what cfm is the head/engine capable of moving? Ie: is a compound/sequential setup overkill air?
-charger sizing, as well as wastegate for atmosphere? Too small would create negative drive pressure ration especially on the small factory. Too big would put the additional cfm and benefit of the atmo passed the working rpm of the 4 cyl.
I love the idea and think it would be awesome.luckily being electronic wastegate tuning can help, but it will be interesting to see it work and be worth while.

I wonder what model this existing turbo is to see what the specs are.

I would look at possibly removing the electronic wastegate controlling system (through tuning should be able to). Utilize the turbo mount from full race

Then go with an internally wastegated EFR charger small frame with similar compressor sizing as factory (will still flow way better). Then go with a small 300 frame as the atmospheric. Maybe a 363 or 364.5? In SXE form they are super efficient and will spool great. If not maybe a 6266 precision on top of the EFR. Or dual precision’s even? Once you utilize that turbo mount, possibilities are pretty endless (barring tuning limitations)
I would think maybe an XDI HPFP to be able to run enough fuel for some E85 could support the air?

Externally gated is the way to go of you want to hold high boost. I just don't understand how much "tuning" is required per additional modification parts to enable high boost, I am only an OBD1 tuner with a mechanical waste-gate.

Correct, typically external will be best for high boost. But with overall efficiency of those EFR’s, and the real estate that is gained/saved in engine compartment from running it, it would be a good high pressure option.
Plus trying to find a way/room to externally wastegate the high pressure, being as there is no manifold since it is a part of the head, would be tough. You wouldn’t be able to modify the Full-Race mount and add the external gate, because being a twin volute setup which runs independently from each exhaust valve, you would actually have to run a riser(betweenT4 mount and turbo) with wastegate in it. Doing an external on these for a high pressure would be difficult.

Manifold is part of the head... haha. What will they think of next
