So, I am contemplating on power upgrades as I will be getting another car soon. While the car is plenty fast in it's own right, I wonder about turbo upgrades.

I read somewhere that the internals for the turbo and N/A models are the same, is this true? could I turbo charge the car with bolting on intake and exhaust housings with any additional hardware, like obviously turbo etc?

Keep in mind I have a 1980 engine, not a 76.

Ewwwww. Sounds like a ton of work but it can be done.

It is possible and been done by others here, but probably much cheaper and certainly much easier to sale your NA buy a turbo.

Can you turbo and NA? Short answer is yes. Long answer is No, NA and Turbo internals are NOT the same. No, you can't just bolt on a turbo. No, you can just bolt on a turbo exhaust mani. No, you can't just bolt on a turbo intake mani.

Read this. The whole thing. Then read it again. Then if anything is unclear, come back and ask clarifying questions.

Depends on whether you want to try and use the factory turbo parts, which are lacking in some areas, but also provide a lot of well thought out engineering work. That requires a lot of work to change over and you'd be better off buying a factory turbo car and swap parts you want from the NA to the turbo (chances are you'd get 5-lug brakes, etc in the process)

If you just want to put a turbo on the NA motor, then you could track down a BAE or Windblown aftermarket turbo manfiold (a simple cast iron "log" that runs to the front of the motor with a flange for the turbo) and put a small turbo on it and figure everything out on your own. There was even a Windblown turbo converted car for sale recently, would make a good donor I think.

If you have a friend that can weld cast iron, you could build a replica using cast iron Weld-El's and some flanges waterjet/laser cut from steel, they show up on eBay from time to time.

Another option that has been done was to build a cross-over pipe off the stock exhaust manifold to mount the turbo on the driver's side, like the 944 turbo.

Lots of work either way with getting exhaust piping routed properly to clear everything and to ensure that critical components don't end up getting damaged via heat.

Biggest issues will be the fuel and ignition tuning as well as ensuring there is enough cooling for the motor. If you keep the stock CIS system, it would need to be modified to handle the addition of boost. An EFI conversion would allow more fine tuning, but isn't exactly easy to do either, depending on your skillset and comfort level.

Ron Davies makes a better radiator that drops into the 924 (or you could adapt a 944/944 turbo radiator, not much different price wise when buying new)

Bottom line, do some searching here and figure out what works best for your skillset, budget and time.

Hey, isnt this the guy who called us names and went coocoo about his modded NA being faster than a 911 on the straights?

Well for what its worth...if you want to be faster than a 911 on the corners turbo is not the right way.

Well think of it is,.. I am getting another car soon and I am thinking of all the different ways to play with this thing.

Turboing seems like to much of a hassle.

V8 LSX swap sounds fun

Electric conversion sounds like fun

so many choices.

Start breeding hybrid super mice hank the na install a pull eyed
exercise wheel and train them mice to run it. ..You could supercharge
might be less hassle than a turbo.

supercharging is in fact much easier as you only need a custom bracket (no need to change any exhaust component)
No need to tap oil feed in your oil pan if you take a sellf oiled unit like a Toyota SC12 used on Aw11 MR2
These superchargers can be found for cheap, I bought 2 for 200$

the electric swap is also very interresting as there are a lot of how to's and once built it is very easy and cheap to repair if it ever brakes.
Battery technology is getting more mainstream and you can buy decent range now.
If I'd ever go that route I would also try to swap most of the steel body parts for fiberglass to keep weight down as much as possible.
