Turbo EFI F100 Progress

[Petrol360]

More updates on the turbo system! Found a local place that sells the stainless pipe and they keep stuff in stock which is nice. So I picked up some 2.5” sch10 for the up pipe. I decided to use a pre made Turbo flange to make things easier and give me some flexibility with the v-band. Mocked everything up and got it all tacked up. Used a runner pipe for the waste gate. I think this will give me good flow to keep the boost in check. I am running a 44mm gate, i know others have used smaller gates but I am planning on running low boost so I think this gate should allow enough exhaust to bypass to keep from boost creeping. If not the up pipe should be easy to remove and modify.

I'm sorry Sir, but I don't believe porn is allowed on this forum.

Still working on the turbo build but took a bit of a turn as far as the EFI system is concerned. Waiting on parts to arrive now.

In other news still rocking the truck NA. Took a 500 mile road trip alongside my dad's 64' F100 (408ci blueprint crate motor). The F100 grand nationals is a cool show for old ford trucks. There was only 3x 300's and one 232ci that I saw out of 1200+ trucks. None of the 300's were turboed of course! Truck ran good but unfortunate the chevy rockers are not getting enough oil to one or two rocker arms and wearing out the ball pivot pretty bad. So I'm getting my second motor ready to be swapped in just in case mine bites the dust!



Really excited to get the turbo in the truck as well but it feels like there are still soooo many more parts to get before I can pull the trigger. Now I am looking into the fuel system and looks like I will be putting a new gas tank under the bed so I can have an in-tank fuel pump. Either way still making progress!

Anything wrong with the stock tank? You could pull the parts from one of millions of Fords that used stock un-baffled tanks, or buy/make your own. It's not a cheap-out, it's a solid sump-free system. The stock Ford system was rated 400+hp from any model or engine type. Just a thought.

Yes- it's in the cab! Still can't believe this design was ever considered. I did witness a death in a truck of this vintage, when an impact caused a tank explosion.

I am going to swap the tank for a few reasons. One it pukes fuel out the filler when its full and I park on a hill. Two its just not set up for a return style EFI fuel system. I could run an in line fuel pump and add a return to the stock tank but going with a new tank will kill more birds in the long run. I believe I can run a 25gal tank from a suburban that is already set up for in tank pump. My dads truck is running a mustang tank that we converted to in tank pump to feed his sniper efi.



I did work on the motor last night. Added a bit of exhaust to the turbo side and getting some parts ready to be blasted and painted. The spare motor looks good but I think I will add some new bearings in the bottom end along with new ARP rod bolts and a high volume oil pump. The bearings I have looked at look ok but the motor does have 190k and will be getting 5-8psi. Plan is to leave the head alone for now and rebuild one of the heads I have laying around with some port works and swap it in later. I already have ARP head studs and a good gasket ready to go.



Wanted to share my progress on a crank trigger wheel for the 300.

Sendcutsend.com will cut parts for you. So if you have CAD you can design parts then get them laser cut. But they also have an online designer tool that you can spec out a custom crank trigger wheel. I picked up a harmonic balancer from Rock auto (photo below) DAYCO PN# PB1496N. It comes up if you look at 1996 f150’s with a 300. Its the only one I know of that has room yo bolt a wheel to the center hub behind the pulley. I used some calipers and made this wheel in there design tool. Around $30 so not bad for a bolt on wheel for the 300 for those looking to go standalone EFI. Will still need a custom bracket for the sensor but one step at a time.



Anyway more progress worth some photos! Thanks for tagging along!

Great work! This is an awesome project! I'll be doing something similar to your crank trigger setup on my 300 build, whenever I get back on that project lol.

What EFI system do you plan on using?

Trigger wheel turned out sweet. Getting the fuel out from behind the seat and lower to the ground will feel good. Your fab skills and attention to detail are inspiring. Right on man. Thanks for sharing.

Also - keeping it on the road while building is rad.

Also just appreciate being upfront about the aesthetics of it being a driving force behind some of those decisions. That's so true for me too. It looks cool man. It will be fun to just listen to that spool up all over town.

An exhaust cut out on a switch with a fender exit that also triggered your boost controller up to like 15psi would be fun.

And these are the days! Sendcutsend, plentiful throttle body options, cheap turbos. Pretty nice times to work on cars all said.
