I was just wondering but what do you guys think would be possible with the 200CID I6 engine? I'm talking about tearing it down and rebuilding it with upgraded internals and everything. What kind of power do you guys think would be possible of comming from this engine? Another matter is that I have a t3 turbo already, would there be any way to use this on the I6 I have already? I don't really know, because I don't understand how turbos work on carburated cars.
If I was you I woud checkout www.fordsix.com a lot great guys over there that really enjoy the inline sixes.
I have built a 200 six with input from that fordsix site. isky 262 cam, .040 off the 250 head and .040 off the block. The valves are the largest that would fit and we unshrouded them, then blended the bowls and cleaned it up in to the intake log. Opened up the exhaust ports and I have a 6 into 1 header and Holley/Weber two barrel to feed the fuel in. HP hopefully is around 175+. Vs 120 from stock. Not earth shattering, but it should get our '63 Ranchero to run real good as that is more HP then the 260 V8 had that year and the 6 weighs less. I have also mated it to a T-5 from a Mustang GT. I plan to do the same things to the 250 in my Mav and the goal is to blow a few V8's in the weeds. The target there will be 200+ HP and that is possible with out to much fuss with an Astrailian cyl. head which fits the 200 and 250, but has a separate intake system. There are two brothers that wrote a book on all the small Ford 6's and they have some great info. They are listed on this sight.
Bob, That stock 120hp is gross. Real net hp is closer to between 95-100 with about 70-75 at the rear wheels. Most stone stock six cylinder Mavs and Mustangs could run about 20 @ 70 mph. With the work you've done, you'll see a significant increase above stock; maybe 160-175 hp, give or take. In a light Falcon/Maverick/Mustang that could mean 130-150 hp at the rear wheels, or as much as double the original output. That would be enough to get the car into the 15 second range. Not earth shattering, but still a fun ride (and faster than a stock Honda).
Turbo! on a stock bottom-end, it should EASILY double the horsepower & torque, at a low RPM, given the turbo is matched properly. All it would take is a JY T3 from a 5-speed (or even auto) turbo coupe, custom header, and some plumbing. As a plus, it would sound sort of like a dump truck LOL.
Well like I said I have a t3 turbo already, I just don't know what else I'd need to make it work on this engine.
Jack, Thanks for the info. I guess my target HP is correct. This should be a real fun motor /car combination. Hopefully I will get it installed this spring.
Your biggest limitation is going to be that carb. It only flows just barely enough to get to that power level. It is a lot smoother, but doesn't get you a lot more capacity. More radical mods in order to accomodate more airflow are needed to get much past the 150hp mark. Some milling to allow a Holley or Autolite 2bbl to bolt directly to the manifold is one route. See MustangGeezer's engine on Fordsix.com, for example.
