i need all the info i can get on these two cars cause i have bought a 1980 indy pace car and i am going to restore it and i need all the info like were the t-tops mirroed or not and what do if the motor is bad and the #'s match what do. i do how do i rebuild the infamous TURBO MOTOR THAT RAN HOTT AND WORE OUT @ 60,000 miles and just general info
-
I would go stock, as they tend to bring more money over modded cars.
With it being a Pace Car, they bring in more as well.
Not sure what info you want, as they have been tons of write-ups on these cars.
Usually the turbos go out before the engine.
Replacement turbos are no big deal, but I would try to keep the heads/block together with matching numbers.
Tell us more about the car, the shape it's in, and post some pictures, so we know where you are in condition of the car.
Feel free to ask exacally what kind of info you need.
Hope this helps somewhat,

Oy difficult read w/o punctuation. Here's a modified version if you're like me...
The trans am's body is in good shape except for the passanger side fender it has been bent. There is no body rust. The inteior is shot. The front nose is in good shape. The t-tops need to be re mirrored if the was from the factory. It need a center console. The shifter is there with the "fish scale plate". I bought the car for 400 dollars sitting out in a feild in north carliona. The guy i got it from did not know what he had. I knew that it was a pace car by the intrior and the paint sceme and the indy decals on the cars fendor

BTW - Nice find for $400. That's what I paid for my 80 base bird.
-
Rebuild the 301 motor to specs do a custom cam tho the factory spec for the cam. I do not know about them running hot, but you could use an aluminum water pump to keep it cool. As long as the motor does not have a hole in the block. Not sure if the T tops are mirrored or not. Look on e bay, see if you can find another t top indy car, or google 80 indy car you should be able to find your answer. Go to 301 garage. com for a little turbo mods nothing major just a little more boost. Hope this helps.
-
Nice find there. Congrat's. Yes, the T-Tops are mirrored, as for the bird and all the decal's, You can get the whole kit, from Hitman, Good Luck.
-
the motor that is in the car rite now is the orginal 301 turbo but the previous owners took the WHOLE TURBO SET UP OFF when the turbocharger went out what do i do now
-
Then you would need to watch the forum classifieds/ebay/etc for a complete turbo setup if you wish to put the 301T back to stock.
I would also highly recommend you pick up a copy of the factory service manual for your car...you will need it.
-
E-bay, Sometime's I've seen the whole turbocharger,1980, 1981, You may have to have it rebuilt.
May take a little time in searchng. I think you also need engine part's #'s book to verify what part's are needed, I think HITMAN carry's them on cd format now.
-
i dont care if it has to be rebuilt i just want the whole set up
-
If ya go through e-bay, Don't forget to look at feedback of the person selling, and find out about shipping cost first. May save ya a headache later on. Good Luck

i know that it is such a head ake

i now have a 301 turbo motor now what do i need to do with it

where can i get the turbo rebuilt at
-
Turbo City out in Orange, California, has kits, and rebuilds turbos.
They advertize in Ricer magazines.
I'm sure that there are places in other cities by you.
Check the phone book in the big cities.
Hope this helps,

George has already given you a good starting point for your search...have you tried them?
-
i kinda dont want to send my turbo off to ca because what would i do if it got lost in the mail
-
Then your only option would be to check your yellow pages for a local shop or buy a kit and attempt it yourself.
-
Uh,
You could insure it. ;)
Or, buy a replacement and pay the extra "core" charge.
George 8)
-
what do you mean by that
-
If they have one in stock(they have used, rebuilt turbos for sale).
Most places don't only just rebuild your turbo.
They have others for auto shops, and charge a "core" charge, which is the price for a "used" unbuilt turbo.
Call them, and see it they have one in stock.
Some replacement turbos also have a adjustable wastegate rod, so you can turn up or down, your boost.
Hope this helps,
George 8)
-
what kind of aftermarket turbo could i use and does my stock turbo have a adjustiable wastegate to up the boost
-
Call them, and they will tell you what turbos you can use.
As for your rod, is it solid all the length?
Or, does it have a two piece, where you can adjust it.
You have to show some pictures of the engine and turbo for anyone to see.

it is just a stock 301 turbo from a 1980 pace car and i dont know anything about turbo motors

At the risk of insulting you, do you know how a turbo is supposed to work? That might sound like a stupid question but a lot of people don't know about them. It just means nobody has told them. :-\
-
If you haven't done it yet, I would suggest again that you order the GM factory service manual on CD that Brett sells on this site and also pick up a couple of engine rebuild books for good measure to help you get an idea of what you are dealing with.
And the easiest thing for you to do is use the internet. Do some searchs on the web, as well as here, and read everything you can get your hands on reagrding T/A's, engines, turbo units, restoration companies, etc....it WILL help. The info isn't going to just fall into your lap...you're going to have to do some research to find all the answers you need for your project. Good luck.

Have you gone through the entire thread here yet:
http://transamcountry.com/forum/viewtopic.php?t=421
If not you might want to. It'll more than likely clear up a bunch of the questions you've asked. And I second/third/fourth everyone's mention that you need to pickup a couple manuals for your car. The one's Brett sells on CD are great because you'll never wear out the pages, get grease smudges on the pages, etc. Haynes and Chilton also produce some manuals which do supplement the CD's. Its these 3 items I've used to reassemble my Y88.

i have checked all around the internet and i just find all the same stuff and i am still lost

That's why I asked the basic question: do you know what a turbo charger is supposed to do? Understanding that concept is fundemental to understanding all the info you find on the web. I'm really not trying to be a smarta$$ -- a lot of people don't know, and it's not necessarily intuitive. Don't be bashful if you don't -- asking is better than not knowing. Just raise your hand if you don't.
-
no you are not being smart i have never fooled with a turbo car all i know is that a turbo forces heat from exaust back into the motor to build pressure
-

Not quite right... A turbo does not force heat back into the motor. What happens is this....exhaust gas from both sides of the engine are routed up to the Turbo. From there it spins an impeller in the turbo itself and then exits the turbo to continue its path down the exhaust system. The spinning impeller sucks/draws air into the intake thereby boosting the total amount of air going into the car.
-
Brian's right -- think of it as the *forcing* more air/fuel into the intake than would be normally possible. The turbo "force feeds" the engine -- stuffs more into it -- and thus causes it to produce more power.
The turbo mechanism is actually two "fans" (or blower impellers) connected by a single shaft. On the exhaust side, the impeller is driven by the exhaust gases after they have left the cylinder and are on their way to the tail pipe. They spin the fan very quickly. The shaft therefore turns just as quickly on the other end. The "fan" (or impeller) on that end is located in the intake side, downstream of the carbuerator. This fan is therefore taking air/fuel and compressing it into the intake manifold. That's how a turbo force-feeds the cylinders.
Really, they don't WANT heat to be transfered from the exhaust into the intake. Preferably the intake mixture would remain fairly cool, because the charge is denser and that carries more power than a hot mixture. Some later turbo engines (not Pontiac) have "intercoolers" to help cool down this compressed intake charge and thus give better power.
The turbo "fans" and shaft spin at pretty high speeds, which is why it's important to keep them oiled and maintained by changing your oil at regular intervals.
So....that's the basics of turbo engine operation. There are other aspects, like "waste gates" and such, but those are just variations and/or options on the basic turbo operation.
Rather than lose you in all of that, I'll just see if you have any questions about this idea so far...it's best to have a firm understanding of the process before we start branching out to other aspects of how it works. :)

Hey Rick,
My later Turbo engine in my Pontiac (1989 20th Anniversary Turbo Trans Am) has an intercooler. ;D
Just letting you know,
