Removing The Twin Turbos 

Chris, Thank you for capturing the real difficulty of this job. It reminds me of how much work went into the design and manufacture of all the components you see here, and the ones you haven't gotten to yet. Most of your difficulty has come from the fact that the hardware you are struggling with is not from Callaway. We use specially sized hardware throughout and someone has changed all that. eg. the exhaust clamp that gave such trouble is not ours, the nuts on the turbine inlet flange are not original, and clearly the last assembler had never heard of anti-sieze. Too bad. All the turbo hardware was installed with the engine in place.

From Calloway Headquarters: What a major job!! Thank you for explaining in detail.... Parts over 30 Years....

It is always a bigger bite of a project. Just got done with a 81 C3 corvette after 1 year of restoration and big improvement.

Snowing here, so just look outside and you will smile !!

I admire your persistence and appreciate this filming of your Callaway journey disassembling and rebuilding your C4 Twin Turbo! Thank you! I check back every week.

Wow, Chris. I can’t even imagine how frustrating it would be to have gone thru all that myself. Frustrating with a capital F! Really feel for you but glad you are so determined. Makes me wonder how the Callaway factory techs felt about installing all that stuff…probly about the same as you! I’ll bet good money you probably are the only private Callaway owner to have ever removed the turbos! With regard to all the hardware removed…I think I would have that all sandblasted or media cleaned then sent off to be either galvanized or maybe even cadmium plated or something that could prevent future rust. What with all the work you are going to put into this car, I would seriously want to keep it after the restoration. But I also know you will need to convert it into funds to be able to continue your channel. Maybe Barrett Jackson is in the cards a year or two from now? The car will certainly be a great candidate for them. Good work, Chris. Keep on making these vids!

Amazing engineering for that era. Glad you have the patients and to complete the removal.

Hmmm with it that difficult I wonder IF the engine is pulled for this and dropped in all together??

Hard work but awesome videos Chris. Keep up the good work! Enjoying following along.

Working on a c4 in general is a pain but a twin turbo OLD ONE NIGHTMARE..... You got it off but imagine putting it all back together 😬😬😬😬

Wow. Im at a loss for words. I don't mind working on my 2000 vette but I'd go nuts on that one.

Chris, I really appreciate your tenacity on this project. It makes my head hurt just to think of working in that area by the oil filter. I am really enjoying watching this restoration. Thank you for sharing.

The Engineering that Calloway had to do initially to design and build the turbo system and get it all working in the car is mind boggling. Congratulations on figuring out how and then to get them removed. It looked completely impossible to me when you were under the car in the last video.

Holy cow that looked difficult. I hope you have a huge sense of accomplishment because the perseverance to complete that removal was remarkable. Keep it up!

Great work, persistence, and dedication. The level of restoration your doing, I recommend removing the engine, if that's a realistic option for you. Keep up the outstanding work and videos.

Great vid Chris!

Buddy!! One step closer my friend. What a job, whew no invy here lol. Thumbs up video ~John

Hi Chris, WOW, just think if you added up the cost of labor for that project alone. Glad to hear that you can have the turbos serviced not too far away.👍👍👌

Chris, I commend you for your perseverance although I got a headache just listening to this ordeal.😂

Great job brother ! You’re a mad scientist at the craft

You have your hands full with this project Chris, it could take you months if not years to get it running. A ton of work but it will be worth it in the end !

Having fun. Chris is the master.

Oh man...you're earning every inch of this project! 👍🏻Respect👍🏻

I would be willing to bet you are the only person in the country that has taken any of these turbos off. I personally have never put a wrench on one of these and I have been turning wrenches in a Chevrolet dealership since the fall of 1985. These cars are very rare. I new about these cars when they came out but have not even had the privilege of seeing one let alone work on one. Good work Chris. It looks to me you have figured out the secret to removing the turbos. Removing the manifolds from the engine so they drop down appears to be the ticket. Very good work sir.

You must be really looking forward to putting it all back together lol. You'll have nightmares thinking about it.

Good Job Chris, welcome to the mechanic life, just be glad all the bolts came out. I usually have to heat them or cut them off, dill and retap them. Keep up the good work.

The turbos!

Please see if Rotomaster will give You a tour for the channel? Thank You for showing how projects go in the real world!

very impressed with your patience! i would have been swearing my ass off!

Your determination is inspiring! 5 hours to remove a bolt!!!

Piece of cake... Now it all smooth sailing from here on... Fingers crossed...

WOW, STRESSED out just listening to your ordeal on this video removing the turbo and you still have one to go. Your right you are probably the only guy that has done this on your own. I admire your tenacity, most guys would have been done. Perseverance does pay off. Like to know your thoughts on the reassemble of this portion of the project. Keep up the great work you do.

You have a helluva lot more patience than I do, Chris!!!

Maybe dropping the motor out might save some time 😉

I skipped through a lot of this video. Enough said. Sending you good vibes while you work on such a cool Vette!

Just said to myself during breakfast where’s Chris been.

The oil cooler lines are a pain, I have the additional challenge of the 4+3 slave cylinder being in the way. I actually though about moving to a remote oil filter to try and gain some space

I was wondering why there hasnt been any videos for a few days now i know why lol

I'd get new bolts. And while it's apart, I'd replace those generic rubber hoses.

Well shit seems like I'm going to be going down this road soon. I'm only an hour out from Callaway and they told me they don't really service these cars anymore. Mine runs and drives, but I just don't have a good feeling about the turbos, and I really want to get them off and sent out.

When you get a price on what rotomaster is charging, please either put it in a video or on your forum thread.

Chris, heck of a project buddy! Do you know if Calloway had specialized tools fabricated for the original install?

Would you be able to put in any turbos on your build? What about a supercharger and turbo mix or a procharger?

How many miles on the car? Why did the turbos need to be serviced?

Did you ever get the Turbos rebuilt? I sent mine to rotomaster and they are saying they are having troubles finding the bearings for them?

Id also think the top oil line would be feed and the bottom return? Would it be easier to remove the turbo and exhaust manifold together as a unit?

Is it possible that Callaway did all this with the engine out? Would it drop back in with all this reinstalled? If so… Uhhh …Chris it has to go back together… yikes! So maybe stop and pull the motor now before you invest more time in the other turbo? How would it be any easier to reverse this process if you can pull the motor? Would Callaway tell you one way or another how they installed the turbos? Motor in or out????

Those purple manifold lines look new… must have been replaced recently?

when you going to have it running?

What is your "busted knuckle count" for this project. I bet it's way up there. Just hope that at the end of all this you are not disappointed in the car itself - performance etc. Good luck with the other one.

Would it have been easier to remove the engine before removing the turbos?

Are you planning on removing the engine and having it rebuilt?

Would it if been easier to pull the motor out and taking it apart with it out ?

It’s easier to remove the turbos by removing the engine. It only takes a couple of hours to remove the engine. Work smart not hard.

All those oil lines, it must take 12 q of oil every oil change.

How many times have you thought to yourself that this might have not been the right project to have selected?

Perhaps it would have been better to take out the engine completely.

Pull engine out

Wouldn't it be better to just pull the motor

Dude, with all the b.s you've gone thru, you're bona have to ask at 40K for this if you plan on selling it.
