I would stick with the efi system on it I really don't think that would be that hard to get that running right take it to someone who can tune turbocharged motors either on an engine dyno or chassis dyno

I think your main problems are going to be a cam and figuring out what size turbo would be best

Your going to want to throw the biggest turbo on there you can but you need to find the right a/r ratio to give you good power throughout the rpm range

To big of a turbo will give you lag for days and your motor might redline before peak boost to small of turbo you'll lose power at midrange

So I'm looking at building a street truck at some point and I want to run something different than everyone else's v8.

I have been reading around on turbo builds for the 300 and its got my creative juices flowing.

So my thought for a turbo 300 6 is pretty simple. Kinda pricey but simple in my mind at least. Everything I have read its straight forward to get a turbo mounted to the engine, I was looking at either the 6.5l Chevy diesel or maybe a t3/t4 hy35 turbo running into an intercooler. And air flow ratio, boost, and egt gauge to monitor it all.

It's seems the tuning and getting everything to run in perfect unison that's the pig of it. After reading all these really cool builds that people have done with efi and ended up fighting the electronics the whole way because of the limitations of the stock system and the megasquirt (most common one I have read people using). All eventually getting it to work but after a lot of time tuning.

So my original idea to get around that was go away from efi with a blow-thru carb easy and simple correction. But, now I'm stuck tuning a carb to try and match the boost correctly and I'm not a carb wiz so tuning would be fairly time consuming and difficult for me.

This is where my mind branched into something even more different. Run a turbo into a Holley Avenger EFI 550-400 conversion kit (That's the pricey part lol)

The Holley system is designed to support 200-400hp, it's self tuning (even for boost and NOS). It will optimize air fuel ratios on the fly in real time all the time come with all the necessary upgraded parts to convert and is designed to operate in the exact power ranges that a turbo 300 would.

Here's my quandary though, it can't be that simple. I'm looking for someone to shoot holes in my idea and sound board with me so that I can perfect it or scrap it if it's not possible.
I myself have seen the Mike's Maverick article and videos and am very impress with what he's done with a almost stock Ford 300. BUT! I also believe that car could have been built alot better and put out lots more power if it was EFI'ed.
At first my thought was to go carb'ed and turbo to make things much easier on me and the pocket but then after a long talk with my uncle thats working on a turbo 2jz dragster recommended to checkout Fuel tech and there EFI tunable system perfect for turbo and very easy to work plus from what ive read its Ford compatible(o2 sensors,positioning sensors)

My ideal turbo 4.9 300 project

•MOTOR
-Forged pistons
-Forged rods
-Heavy valve springs(like the Mav.)
-High pressure oil pump

Might be missing afew things...

•Exhaust and Intake
-Bronco header with custom turbo flange.
-Garrett turbo T3-T4
-Ebay Intercooler kit

The only thing I havent looked for is the trottle body. Would have use stock but its a double barrel body. :/

•FUEL
-High volume internal fuel pump
-Fuel pressure regulator on firewall
-Stock fuel rail
-The biggest OEM Injectors you can find (cause the fuel tech system tunes so better safe than sorry)

And top it off with a nice MSD system and a 4in down pipe with no need of a muffler

well the truck I'm looking at getting doesn't have a stock efi system. It's a 1983 f100 with a carbed v6 (Dont think that's the motor that came in the truck but the guy who has it says he is the original owner and didn't swap it, so I'm gonna take his word on it). I will be getting a motor from the junkyard or Craigslits or something and building from there. I like simplicity and uniqueness, I don't want to drive anything that's like someone else's. I might spend a little more to achieve this in this build but I think it can all come together really nicely.

Diesel, that offy intake was the one I was looking at getting to run the setup.

Well that changes things yeah I would go with whatever is easiest or whatever motor you come across first

That makes tuning easier then just build whichever motor on the stand then take it to an engine dyno for tuning

Talked to the guys at Holley. They told me that the avenger, hp, and dominatir efi systems are all capable of handling boosted applications. However all the systems would needed to have parameters set via computer before the system can start self tuning and doing what it would on a naturally aspirated engine.

Seems like this idea is pretty feasable.
