Questions on turbo 200

[Anonymous]

I have a 64' Fairlane with the original 200 six... but I have some questions.

1) How much compression should I run with 10 pounds of boost?

2) Can I use the Turbo off of an early Cummins "B" Model engine (The one used in Dodge Rams,) as long as I put a "softer" spring in the waste gate?

3) What is the best turbo I can get for the engine, without having a lot of lag off the line?

4) If I am getting this correctly, can I run a J-pipe to the turbo, run the suction side of the turbo through an aftercooler, then right to the carburetor?

5) Is a 350 Holley 2 bbl sufficient to feed the engine, or should I get the bigger 500 CFM?

6) How much horsepower can I expect to make at the crank with this set up?

7) Is the comp cams 260H a good choice for the 200

8) Where can I buy one of those carburetor hats, or do I have to custom make one?

9) Whats the fuel economy going to be like with this engine?

Sorry about all of the questions...

Do a little more research to begin with. I'm fairly new and alot of these questions have been answered. I'll give ya my opinion though.

1 Psi is NOT repeat NOT the factor you need to worry about with a turbo. The size and flow of the turbo determine whether or not its safe and the compression you should run. 10 psi on a medium/small turbo SHOULD be fine. If you don't know the turbo we can't help too much. Compression wise you should run roughly 8.5-9 to 1 as that is a really safe compression for turbo setups.

2 You can run a turbo off anything that you want to. It depends on what you want to do. Those turbo's are Holsets, they are really nice turbos and can make really good power on a 2.0 (there are companies selling conversion kits for dsm's) They should have decent size and spool for a 3.3.

3 There are numerous turbo's you can buy that would do what you want. Btw what do you want? What kind of spool by what rpm? Want a turbo that is going to pull hard up top too?

4 You are partially right. You can run a J pipe. However The suction side of the turbo is the intake of the turbo. You would put an intercooler/aftercooler after the outlet of the turbo or on the charge side. The routing sounds simple but is fairly complex to actually run sometimes.

5 A 350 will be more than adequate but be prepared to modify the carb to work right.

6 We need to know more than you have a 200 and think you might use a Cummin turbo to tell you a horsepower estimate.

7 A stock one? What else do you have to tell us about the combo so we can make an informed cam choice?

8 Try turbonetics. Depends on the carb your going to use.

9 The more you keep your foot out of boost the better it will be.

Questions are cool we just need more information to be able to help you pretty much at all.

Ok, I'm going to be getting a rebuild kit from the Ford Six shop,

The Fairlane will be a daily driver, so I want mostly streetable hp and torque, that why I want a lot of low end,

I will probably be changing the tranny to a T5 when I do the engine rebuild,


Thanks for all the help you have given me.

1) stock compression ratio and stock cast pistons are perfectly fine for 10 psi.
2) Dodge Ram Cummins engines used aither HY35 or HX35 Holsets, either will work well on a 200.
3) There are many!
4) Aftercooler comes after the turbo, nice to have. If it isn't in the budget for now, or hard to find room to mount it, you can add it later for more power (cooler charge).
5) The Holley 350 is the ideal size. I plan to use an Autolite 2 bbl in my next build because I believe they are a superior design to the holley.
6) HP depends on a LOT of things!!!
7) It'll work well enough. The stock cam works very well as a turbo cam for a mild application (such as yours)
8 ) Any carb hat that will fit a 4 bbl will fit either a holley or Autolite 2 bbl. Some guys have used "propane carb" hats as a bonnet!
9) When you make boost, the gas gauge will go down fast. That is what HP is!! Turning liquid fuel into speed. On a 13 second run, at 22 psi I was burning 2/3'rds a gallon of gas per 1/4 mile!!

Thanks for the reply Linc, I read your sticky on the Forced Induction forum, very good information. I'll keep you all posted on my progress, although any engine work will be taking place next year (I'm concentrationg on getting my Fairlane road ready by the time I get my license) as this will be my senior project for school. Thanks

That is wise.... the 200 six has one of the worst cylinder head designs known to man. It stops flowing well around 4000 RPM's.

It IS good for making low end torque, though....
and BOOST will fix that airflow problem at 4000!
