i want to turbocharge my i6 300 in an f-250 and i have seen a thread about a guy who used one from a gm 6.5 but how much custom fab work would i have to do? im on a budget and i was just wondering if there was another turbo or if the 6.5 turbo would be the best bet. also would i have to change my Fuel Injectors to bigger ones? like out of a 302? thanks.
Let us know when you start.
We have great input and lots of combined knowledge.
If you are serious then I'd get a 5.9 cummins turbo called hx35.
You can redneck install it by twisting exhaust around to connect with turbo or you can build a decent log exh manifold.
You get a 5psi wastegate to hook up
Not sure if you have checked any of these links out yet but here are a few that I found for performance and what not. I was in the process of building a model T or a T bucket but I didnt want to use the standard V8 and wanted something diffrent so I bought a 66 Mustang driveline, ford inline 6 200ci with C4 auto behind it, but i was going to turbo it because if done right you can build more power then a v8. There is a few guys who race these bigger sixes and know how to turbo them and make massive power out of it. I sent them an email and they sent me alot of info on how to go about building a turbo six. Anyway Ive heard a turbo for a Grand national is perfect for the inline sixes
HE341 is just as good. It's a nice sized exh housing a d flows good air.
The gn turbo isnt big enough. It will spool great but run out on the top if you do actually build an engine later on.
The manifold you make doesn't need to be engineered. Look at the cummins manifold. Tight bends and log style. Turbos like velocity. So a log directing all flow at high pressure isnt bad. The 300 is a terrible head design anyway. It's not like you're putting a crappy home built manifold on a 32v all alum Audi engine that flows crazy numbers.
Don't worry about it. Find some nice bends and build from your current exh manifolds forward and together. A t3 flange is what's on he turbo already so your good. Make a brace off the engine to hold turbo up at the flange as well. Oil feed can be t'eed off the oil sending unit and then get a drain into oilpan somehow.
Turbos are easy to custom do. Supercharges are a little more tricky. Need to be rigid and belt alignment then add an idler for correct belt wrap and stuff.
A turbo on an f150 300-6 would take me a day to build.
If I owned a 300-6 truck I'd build a kit and stress test it, then produce them. Cause it would be something I'd enjoy building in my shop. I love building stuff people say is rediculous or hard.
I gotta say putting a custom supercharger on the corrado was way tougher then the turbo kit I built for a miata. And the vw had WAY more room to work.
Yea they are but the company I talked with that gave me advice had turboed both 200 and 300 they liked the 300 because it could withstand more boost when done right. When i started looking into a turbo six i was told to find a 300 but couldnt do that around here without buying a truck but i found the 200 for 60 bucks with a transmission so it worked for me

Yeah the 300 is a freakin tank compared to the 200. But the 200 is light.
The 300 has giant bearings compared to the 200. But both have awesome potential because of the 7 main bearings.
I've always wanted to turbo a 300 just because. But I've never had a truck with one.
Lots of aftermarket for both if you know where to look.
