There's a turbocharger calculator here:

Its not as simple as just picking a turbo form a junkyard car. You should read "Maximum Boost" and other turbo system design books first.

| Post subject: | What size turbo |
I have a 65 dart with a 225. iam wanting to biuld a turbo small block but want to use the 6 to get fimiliar with turbo's. This turbo will go on my stock 6. I picked up a 2bl set up and will run a blow threw carb. The car will be raced more than street driven Will have an 8 3/4 installed From what ive found from searching iam looking for a turbo off of a 2.0 to 4.0 motor.....AR around .90ish. I found a few off Grand National's . Some Holset off 6cyl cummins. is that roughly what iam looking for? I also will be doing the work myself. I biuld all my own motors for my bikes and mopars in the pass. keep in mind i will be useing this as a learning curve to learn turbo's for a better set up later on. All parts will be 2nd hand if possiable thanks for any input. |

I used a stock 87GN turbo and it was good enough for high 12s with a stock 225. .63ar. My "good" turbo is still .63ar. |

The Buick GN turbo is a great starting point, and there are plenty of used ones around. turbobuick.com is a good place to look. Lou |

I love your biuld..... It makes me laugh...15 years ago I had a 69 charger with a just about stock 440 with a purple shalf cam....the car was pretty much striped down and ran 12.50's.....To see a ole 6 running low 12's is awsome. I know theres a more technical ways to picking a turbo but i dont know what to expect. The 1st thing i would do is see how much a stock motor can take. See what kind of times it puts out. Take all I've learned from blowing up that motor and biuld another motor to handle more of everything is all i know to do....hell, Its what i've done with everything else and seem to work pretty good...lol Thanks for the replys guys.... |

A GN turbo, HX35, or HX40 would probably be a pretty decent starting point. |

The TB03 used in a Grand national may be a bit large for the stock intake and carburetor. rejetting the carb to compensate for more airflow while making it a blowthru set up can give you better results. What is your target HP and Ib.s of boost? If you want to reap power from the car, I'd go with a 4BBl. carb and intake. Otherwise the stock intake will definitely restrict some CFM the Grand National or similar turbo can make. try a TA34, 466159-5005S this may be a bit agressive, but it has potential to support future mods.

Way back before turbos were the rage I put a corvair turbo on a 170 slant six for a Bantam Altered race car. pics are on my website. It was around 1976. It worked very well for back then. I used the Corvair Carter carb first bt then built a adapter for a small Holley 4bbl. Car was owned and driven by Stu Denyes and ruled the old Mohawk strip inSmallblock class during the run what ya brung days. It was also raced very successfully at Cayuga Ontario .I have often thought about two Daytona tubos just forthe fun of it. 3 and 3 Don |

Investing in a good wide band air-fuel gauge will go a long way toward preventing an engine meltdown. I ran a carter BBD on a blowthrew turbo setup for 3 years,and I don't recommend it.I had to make fuel metering rods out of AFB ones and I fooled with the air bleeds for a long time. |

I tried a Carter BBD on my corvair turboed 170, in a draw thru, and the needle/seat couldn't flow enough fuel to keep the float bowl full. |
