This week's update, I added a couple of items to the firewall, the wooden "Master Vibrator" box will be used to house the fuel pump, horn, and other relays. The amp gauge will not be used, but looks pretty neat anyway.

Today I received a 2.5L Chrysler turbo from eBay, it cost me a whole $.99 plus $23 shipping. The first pics are as received.

I then removed all the EGR valve crap that I can't use since I'm going draw thru.

The listing said it was stuck from sitting, so a little work and some PB Blaster, and it turns freely. All it was was a little corrosion on the exhaust side, easily fixed, and I plan on going through it completely anyway to put in a positive oil seal to prevent it from pulling oil into the intake when I close the throttle.

So now I decided to compare the intake side of the turbo to the HS6 S.U. carb I plan on using, PERFECT MATCH!!! On the second pic, you can see the turbo housing sitting on the S.U. carb, and the butterfly through the hole. I got lucky and picked just the right size.

Now all I need to do is find one more turbo, and I can start on the intake and exhaust setup.

The reason why I chose the Chrysler turbos is because they're small so they'll spool up faster, and they're water cooled, so I'm thinking they'll last longer. Also, since they're OEM, they should be higher quality than some of the "Chinese" turbos presently on eBay.

you'll be lucky if you get 3 psi out of that thing....they were only about 4-5 new...and that thing being old and crusty...even when cleaned....may only put out about 2-3 psi. but maybe that is why you are going twin turbo and it probably makes more since to go low on that motor.

also why are you mounting the turbo straight to the carb...wouldn't you want some tubing between the two so you give the air time to settle before vortexing into the motor. maybe it doesn't matter, but i know it does on EFI w/ MAF sensor....otherwise your MAF will freak out bad if it is too close to the source of push.

also is that a single barrel.....i think that probably the chrysler turbo is used to alittle more fuel then can bee afforded by a single barrel carb.

just thinking way the hell outside the box here, but kudos to you on a freaking awesome project! i hope it DOES work i want to see it and learn from it.

sweet!!

The Garrett turbos from the mid '80s Chryslers are good for 25 psi, so I'm not too worried about it, and I plan on rebuilding it anyway. As for the carb, it won't be "directly" bolted to the turbo, it'll be about 5" away from it to help with heat soak. I chose the smaller HS6 over the 2" HS8 for better throttle response. Remember, this is a 327 cid engine, and a flathead at that. I have two of the carbs, one for each turbo. With a max rpm of 4000, I don't need much, I'm aiming more for low end torque.

In the spirit of "doing a little each night" I decided to try and figure out the e-brake setup tonight. I think I came up with an elegant solution, using the discarded master cylinder bracket that was riveted to the chassis and in my way anyway. The e-brake handle is off from God knows what, but is the perfect size to be comfortable to use. The upper hole mounts the handle, and the two lower holes will hold the cables and ratchet mechanism eventually. Keep in mind this is all a mock up, but I think I'll use it as-is. Opinions??

After much thought on how to mount the turbo's and the carbs, and even considering drawing from one single 4bbl carb in between the two turbos, I did some head scratching tonight out in the garage, and decided that this would be the best way to go, so I mocked it up. Now, the turbo's will sit higher than it is in this pic, about 3" or 4" or so, hopefully no higher. Also, forgive my use of the paper towel roll, but it's the perfect size for the inside of both the turbo intake and the HS6 intake. The beauty of all this is that it solves a multitude of problems, and keeps the carb away from the heat of the turbo's. It also allows me to have plenty of room to run carb linkage, oil lines, and coolant lines for the turbo's. And since I plan on using an electric fuel pump, the fuel line can run on the driver's side of the car, so I won't have to run around in front of the engine with a fuel line from the fuel pump. Whatcha all think?

P.S., I think Mal came up with this idea months ago, but I didn't want to do it because I didn't want the carbs to go over the engine. But now that I look at it, I actually like it!
