Hello and wellcome to PP!

Now few hints:

It is very very common to see newcomers with impressive build sheets. You need to think trough it a bit.

If your goal is high HP, I suggest ditching the 3.3 alltogether and building on 3.6 instead. Trust me, required amount of work/money to raise 3.3L to 700hp-ish is much greater than work to do the same on 3.6L.

3.6L N/A already has twin plugged heads that flow well + greater volume to boot (to help low-range torque). Further on, VNT turbochargers that can survive gasoline temperatures are very very scarce. Only modern example I know of is the pair that sits on 997 Turbo. I suggest going for ordinary Garret BB's.

EFI is least of your problems, there at least five different types that can do what you want. Heck, even a MegaSquirt will do it.

Autronic, Haltech, SDS, Nira, MTE, name it. They all do that stuff...opening ans closing injectors, firing plugs and controlling the boost. It's just a matter of finding one that your dyno shop is used to.

To conclude:

If you want big power (500+), building on 3.3 engine is not cost-effective. 3.6 gives much more headroom than 3.3. Saying "but I already have a 3.3, shouldn't I use it?" is fooling yourself. Build check for such power will be much greater than cost of core-engine itself. It's better to sell the 3.3 alltogether and buy 3.6 than shelling out 3x engines worth to change parts 3.3 that cannot be used.

Good luck!
Thank you for your time,
