Hello, I am a newbie here but not in the mopar world. i am building a rat rod 53 dodge/desoto. Instead of the usual removal of the flat six engine to a v-8hemi, I have taken the route to go with a turbo off a 1986 mitsubishi and re-use the flat six engine. I would like to see if anyone out there can provide info, specs, or ideas on this project. The unit should be arriving this coming week (tues. or Wed.) Stay tuned for this wacky thread I guarante you it will not dissapoint from the rookie to the experts... Please feel free to ask and answer any questions, Your support and input as this will be my first.

Which 6 are you using? If you want to buid the Dodge 230 Cu In version, check with Jasper engines, or a local Fork lift repair shop, they were used into the early 70's in industrial applications with things like sodium filled valves and hardened valve seats for running on propane, these would be beneficial with a turbo. The crankshafts on the FH 6's from mopar are going to be the Achilles heel for your motor, (along with airflow) Look into some nascar history, they were pretty popular in the early 50's stock car racing, ane many had some unique oiling mods with external lines to help oil flow to the mains. About 15 years ago a team built a Chrysler flat head 8 for Bonneville with a B&M blower, the 8 was pretty closely related to the 6, so some info may be floating around from them. Call Pertronix in CA, they make a nice drop in module for the ditributor to eliminate the points and give you an electronic ignition. There wwere HP aluminum heads that were reproduced a few years ago also. There is some good info on some Power Wagon sites for engine mods as well. Good luck with your project.

I am running a 230 Cu. In. flat six, with a single barrel rochester carburator. I was under the impression that the airflow was the only major component of the turbo. I am interested to know if the stock crankshaft if going to hold? I am on the hunt for that pertonics electronic ignition, I just send the carb. to be rebuild. I am currently looking for a dual exaust set up or I may need to send mine out to be split...

turbo is too small, I'm assuming its off of a conquest or a starion, First thing I would suggest is a bigger turbo and a blow through carb. Also check out www.homemadeturbo.com
I agree that the hot side is way to restrictive for all-out power, but would be a killer DD.:)

I think your turbo will be fine, the flat head motor will flat out not flow much air, no matter how much boost you run, and it will not spin much RPMs and live. I'd say 4500 RPM is REALLY pushing it for a Flat head 6, unless you go with lighter pistons/rods etc...

So what happened with this project?

I'd really like to know because I just got a 1950 230 ci Dodge Flathead for $30bucks last week and had a similar idea. Great minds think for alike.

How strong is this crank really? I can't find any info.


Sin,
ShelbySean
