Turbo in non-turbo engine
Is there any possibility of adding a turbo to a non-turbo porsche 911 engine? I'm looking between 1986 and 1989. Is this even a good idea? Just getting into this so bear with me if this is a stupid question.

Yes I have an 89 with a Protosport set up. Call prototech he is in Cali and speak to Todd. Also do a search

Its a wonderful idea-search Protomotive or Protosport.
Keep in mind its a slippery slope.

Yes, it's a great upgrade. Now, if I could just afford that 930 gearbox...

![]() Without touching the engine internals, you can extract 400HP @ 0.7bar of boost (intercooled of course). Otherwise, approx 340-360HP @ 0.5bar, non-intercooled ![]() You're better off getting a tougher G50 based car for future upgrades. They'll pretty much handle anything you throw at them ![]()

Their prices seem terribly expensive.

The 915 will handle that, and more, easily. It all comes down to how you treat the box. Be gentle and it will handle that power easily.

To3 is marginal, T03/4 is better. You'd get 300 hp easily even with a T03.You'll need a rising rate fpr and a chip, the chip is the problem unless you could care less about intellectual property and are willing to just burn someone else's.
MB911 and Souk are both working on systems less expensive than Proto's. MB thinks his price will be substantially less than Proto's, we'll see. Proto isn't really outrageous if you look at what you'd pay at retail to assemble your own system; if you can bend/flange pipe and can do the chip, then yeah, its pricey, but not many folks can do that. As to what the 915 will handle, 400 hp seems to be no problem unless you're into drag racing; the lag itself protects the trans on the street unless you don't respect mechanical things generally.

Proto typically uses a T04B type setup in their systems. Their fabrication work is of a very high quality. You get what you pay for that's for sure.
Either way, a blown 3.2 will put a smile on your face. try to hook up with a member on this Forum who's done the conversion and you'll see first hand what it's like.

If you are currently rebuilding your 915 now is the time to add some bolt-on strength. The WEVO twin bearing retainer and a reinforced side cover are good to have. A posi unit is very good protection due to the torque being spread to both axles.

I guess if you knew what a turboed 3.2 felt like you would not be contemplating selling. Right Merv....
Since my conversion I have clocked about 800 spirited miles.....and the smile just doesn't leave my face. Be prepaired to drop some serious coin as once you do the turbo then come the big brakes, suspension...etc...
