hi guys i just finshed my turbo set up on my 85 and its bad ass fast as **** but im going ot go with a SC soon to go even faster so im going to sell my turbo set up will fit on all f150-f350 300ci L6 will not fit 4x4 if you have a 4x4 i can make one for your app. i have all mounting parts but you will need to sulppy oil lines if you live close to dayton ohio i can install it send me an email if your interrested under_hz_master@yahoo.com

I live in Dayton and would be interested to see this setup.
Well to answer some questions for everyone. Here is the summary of the whole project.
1989 4x4 F150
engine: 300-6 bone stock and 140K miles to top it off.
clutch: 10 inch disc...Its time for an 11" this one slips under boost
transmision: Borg Warner T-18 4spd.
transfercase Borg Warner 1356
gears 3.54:1
Turbo: Warner-Ishi from 6.5 GM diesel
Piping: custom fabbed by myself
Target boost pressure: 10PSI have run as high as 15 PSI.
Fuel management: Megasquirt and spark using stock distributor and TFI, Dynojet wide band air fuel guage controlling fuel ratios
Wiring harness: OEM..removed 60pin EEC-IV header connector from scrap ECU and built a "plug and play" wiring harness adapter.
Fuel economy: 14.2 MPG HWY when I'm not hogging on it. I expect to get 15-17 range when completely dialed in.
Why?: 1. I want to prove that economy and power are acheivable
2. I'm tired of the common small block, big block game everyone and their cousin has run and currently runs.
3. The 300-I6 was used as an industrial engine on used equipment and is built very well with its 7 main bearings and is about perfect for this kind of application.
Current miles on projet: 14K abusive miles, and now that I have everything dialed in much better I haven't really seen any adverse effects on the engine.
I have a 83 f150 4x4 with 300 I6 180k Miles. Timing gear broke so i'm rebuilding it but i want to see your pictures of your turboed 300 to get an idea of what need to get and make for it. It's all oem excoulding the starter, fuel pump, head and general maintence. It thinks it's a semi. it sound like one and it will look more like one after i get the motor done an the new exhuast stack on. ;-)
Question and idea for you 300turbo. are you cooling the oil that comes back from the turbo or is it just dumping right back onto the pan. Idea use a radiator for automatic transmission and use a remote tank with an electric pump. Hook the tank up to the pump. Pump to the turbo. Turbo to the radiator. Radiator to a remote filter and filter to the tank. The turbo stays lubed and reduces the break down of the oil in the engine.

Go to the "megasquirt" website and check out the "megasquirt and spark" ECM. For the moment, that's what he's using to run the engine. It runs really well with the MS system, but he's in the process of developing his own ECM that has far greater capacity as the MS system is pretty "simple".
I just put a borg warner 6.5 chevy diesel turbo on my 89 F150 EFI 300. It works incredibly well the power is amazing. I can easily keep up with a 351. boost starts at about 1500 RPM and peaks out with 9 lbs at 2500-3000. I had to change fuel injectors from 15lbs to 21 lbs 302 injectors. I also had a rich cold start condition that I fixed by adding a resister in parallel with the CTS..Now for the BIG technical question.. Will the factory speed density system run in closed loop utilizing O2 sensor IF the MAP sensor is getting 0inches or positive pressure while the TPS is at half throttle. Also I wonder if the computer in closed loop mode will be able to reduce the pulse width enough on the injectors so it will not be running too rich. I havent yet installed the 02 sensor yet. This thing is great but I am trying to retain some MPG when im not hogging on it.. Any input would be great. Thanks
Hello everyone, I haven't posted in a while. Here is a quick status run down on the turbo project. The rebuild I did a year ago after cracking 2 of the sealed power hypereutectic pistons, I replaced the pistons with custom ordered Wiseco's and Total seal gap-less rings. I have now about 7000 trouble free miles on the whole setup. The MegaSquirt ECU could probably go for a little bit more fine tuning. All in all I think I have found the right combination of fuel, timing, and boost for a reliable setup. I have run this turbo setup for about 4 yrs. now and have learned tons of info. Now I'm on to a different animal, I just purchased a 99 powerstroke so I'm going to play around with diesels for awhile. I am thinking about selling the turbo project pickup to pay off the debt I have racked up building it. I would probably let this project go for about $3500 and will be regretting selling it every step of the way. No aspect of this pickup has been untouched. I rebuilt the rear diff, transfercase, transmission, front diff, all new U-Joints, clutch, engine twice, new tires...uhhgg...Damn money anyway...
hi folks, finaly joined this site after 3 yrs of browsing. after much planning and reading corky bells " maximum boost " cover to cover many times over i am now coming down the home stretch on my turbo project. like so many others who have the 4.9 i was always looking for a way to get more power and came to the conc. that this was the best way to go. my set up includes the 6.5 b.w. turbo, stock inj , a vortech fmu ,bypass valve and an intercooler. boost and air/ fuel ratio gauge in dash. i figure i will have some bugs to work out on the fuel management end of it but have to start somewhere. one thing has me going is the wastegate spring setup on turbo 300 six's rig .i always thought you needed a boost sig to activate wastegate.anybody? oh well talked enough.
The drive pressure of the turbo opens the wastegate and the spring regulates the pressure it takes to open it...It's not the most elegant way to control boost but it does work. A wastegate actuator does the same thing. Inside of one there is a spring and a diaphram. The spring is strong enough to keep the wastegate closed under all boost pressures so boost reference is placed behind the diaphram to help push against spring. With the combined forces of turbo drive pressure and boost the wastegate opens.
Thanks for the reply. Didn't know if you were coming back to this site. Thanks for clarifying that for me, I have a good selec of springs layin around the garage. Made a bracket to mount a spring w an adjustment bolt on the turbo itself as mine is mounted up and forward from your setup. I hooked a spring scale up to the wg lever and set the spring to open it at 5 lbs. Don't know if that will work or not. About two more days and its fire up time. This thing was way more work than I ever thought but is by far the best winter project I've ever done. I drive a turbo saab 900 back and forth to work. These have what they call an APC set up to open the wastegate right at the edge of detonation. Works with the knock sensor. Would be something to adapt that over to the 300. Well a few more details such as modifying the pcv system, a check valve to the map sensor and painting the pipes a pretty blue. Can't wait to show it to someone other than my wife who just said yea , what am I looking at? Like I said ,I don't know what the air/ fuel ratio gauge will say when the boost kicks in but I guess I'll find out. Will post some pics when my college boy comes home show me how. Wouldn't have even tried this if I hadn't stumbled across your forum thread on this. Good luck with the powerstroke.

Reason: misspelled college
The stock ECU is pretty good at keeping detonation down. I am curious how that rising rate fuel pressure regulator will work for you. In an attempt to richen mine up I blocked off the return and deadheaded the pump but could only get about 50 lbs. from 42..my pump might be a little weak. That's when I did the 302 19lbs injectors.
