Efi 170 i6 ???

Corrected. They've turboed some Mustangs, but Bronco's are scarce on Fordsix.

So I'm gonna do this just cause now. I'll run 1 injector per port for a true SEFI. Maybe 2 or 4 injectors at the throttle body for when I boost. Depends if it's needed or not. 1 coil per cylinder as well. I can't remember if the AEM box has 5 coil outputs or more... So possibly wasted spark, hopefully a single fire though. I'll have to check into it again. Another Motec trigger wheel/Cherry Hall effect sensor and 5.0L cam sync sensor. That combo works great on my other AEM project. The hardest part of this swap is the fuel system. I want a sustained 40-45psi. I'd prefer a fuel cell, but I can't find one to fit properly. This could be fun.. Until the little engine blows up. hahaha.;D

I'd love to see you get this done..although were it me I'd want the much stouter bottom end of the 7-main 200.

Oh..and a turbo is a must too. ;D

i think the 300 six (Ford 1/2 ton) was fuel injected in the later part of the 80's but i don't think there is a lot of crossover parts to the small six??? go with a 300 and get the bonus of all that torque

 

[t120r]

But my truck came with the 170 WHEN it blows up, I'll figure something out. Maybe a 200... Maybe a 300... Maybe my 608HP 441cid BBF/ZF combo. Who knows?

A little update: Just finished moving. I have myself a nice garage to work in now. The EB project should start moving along nicely.

I ditched the Honda AEM unit for a 30-1400 Mustang box. I'm more familiar with it and the guy threw in a dual channel wideband controller. Will make tuning a lot easier.

I picked up an Aeromotive weld in fuel tank sump. My tank is in decent shape, so it's worth modifying a bit. I'm gonna go with an external fuel pump for the ease of it. I love my Aeromotive pump on my ranger, but it's crazy overkill for a 170. Does leave room for future upgrades though.

I need to find that link where someone milled off the intake of their 170 and fabbed a custom intake. Anyone know the one I'm talking about?

 

[graniteguy]

I've seen plenty where they milled the top to attach a 2barrel carb. I've got a 67 stang and all that is lacking to drive it is a carb that fits. I made my own adapter and darn it the hood won't close. It starts though. lol

I found fordsix after making the adapter on my own (blindly). Gonna have to suck it up and remove the cylinder head and get it milled.

 

[t120r]

The pictures/writeup I saw was where someone completely milled off the intake and made a flange to bolt on an aftermarket/custom intake. Was pretty neat. I haven't been able to find it since.

I've seen a couple over on fordsix.com, but never seen none actually finished and working. The ones I seen where similar to fabbing your own headers.

 

[t120r]

Well, I have the Aeroquip socketless hose in the mail for plumbing the fuel system. I have an aeromotive reg and a walbro 255lph pump. My buddy has an aluminum crossflow head in the mail for me as well. Should be interesting.

Is the Aeromotive pump loud and where did you get it from? I have an external pump on my EFI and it squeals like crazy. I'm hoping it gets a little quieter after I get everything done.

I like the Holley Pro-jection systems. Its a TBI system that sits right where your carb used to be. They have a small version for 6 cyl engines. It is self contained, super easy to install and reasonably cheap on ebay.

 

[t120r]

The aeromotive pump is loud... That's why they have rubber isolators as a mounting kit and a fuel pump controller to slow it down when you're not into the throttle. It's made for performance. I have one in my Ranger and you can hear it all the time. I'm going with a quieter pump for the EB cause it just won't need as much fuel delivery as my big block.

For a cheap easy kit, by all means go TBI. Just isn't for me. I need SEFI or I don't see the advantage over a good tuned carb. There may be one, just for me to justify any money, it has to have a noticeable/quantifiable difference.
