So after my dad suddenly had an urge to engine swap his already modified 70 Chevelle, I found myself with two turbos. To be precise, I found myself with two Garrett A/R .70 M24 turbos. Now, I wouldn't say I'm well versed in turbo knowledge which is why I'm here asking for help and opinions. After gaining these turbos, I had the idea of "hey let's slap those bitches on the G." But after considering all the things I could think of, I have some general questions. 1. if I'm going to go FI, I figured I might as well do things right and get forged internals to hold the boost without me throwing a rod, so does anyone have any recommendations for companies that sell well made and decently priced forged internals? 2. With everything (engine wise) said and done on the car, how long would it take for a shop to complete this, considering possible custom fabrication, custom parts, etc? 3. How much money would this cost (approximately)? 4. As I said before I'm not very knowledgeable with turbos yet so if i had forged internals and everything set, how much PSI could I expect to push, and how much horsepower would I possibly be good for(approximately)? 5. As a general question about turbos, is there a way to have separate maps set up so I could press a few buttons and change from an aggressive tune/more PSI setup to a less aggressive/more daily driven set up?

I know it was a lot of questions and not many answers will be exact but anything helps!
Thanks

 

Being as this is your first post, please use the search feature. Your asking a lot of questions that have been asked already. You said you are not too knowledgeable about turbo setups so do the research and learn. There is a TON of info on here, been here 6 years.

Minimum $10k-$15k for a single setup. $20k-$25k for a twin. Gotta pay to play.

 

Extremely expensive if you have someone else do it. fabricate your own.. its actually not as hard as you think and a hell of a lot cheaper.. maybe find a used turbo kit.. to off set balance maybe sell the turbo's and use that money for a used supercharger kit. how much horsepower are you going for? I personally prefer turbo over supercharger.. but the superchargers are a lot cheaper for these cars.
