My stock bought about 10 years ago is made in Brazil. I am not sure if this is an improvement to the one before (leaking too and then failed) from Germany

Hi
I like this project. but dont use a SC fuelhead, If you do, add 3 extra injectors
and also a pressure switch to activate the injectors. This is so simple.
If possible, try to find a a fuelhead from a 928 or a MB 560-1988.

Good Luck
DPHANS

The factory 3.3L with very low compression ratio cannot run reliably past 0.8 Bar.

A compression ratio of 9.3:1 will greatly limit the boost, so @0.5, that sounds about right.

Are you doing anything to your clutch package to take up that additional Torque? The standard 5-Speed 915 tranny was too weak for a 245HP 1975-77 3.0L Turbo, hence the standard 4-speed on the 930 until much later, when they went to a 5-speed.

Good luck!

I did a transplant on my 82SC-Targa with a 3.3 turbo-(Top end rebuild 1994)-Cams,polished,7006,AIC-HKS,..ETC..ETC.. My car is at 380-400 to the wheels. Plus being a lightweight car, its no joke. I use my car strictly for HWY-TOP END--60-130MPH +-No drag races.

I did rebuild the 915 tansmission and still have an organic clutch. No problems that area. I have currently 15,000+ miles on the engine and the 915.

Just-relax in 1ST AND 2ND GEAR. You will be fine. INMOP.

I recommend a leakdown test when you get it running. Good luck.

By the looks of it, he is dumping the oil back into the oil tank vent. It would be nice to see a detailed pic of that setup. This is what I had originally planned on doing before I sourced a turbo oil tank but I hadn't figured out how to make it work while still using a catch can.

Awesome project TIM.G 911 :-)

Any chance of some extra details and images of how you did your customer airbox?

Cheers

Oil

Oil from the turbo is being returned to the vent side of the oil tank thru an R.B. RACING electric spur gear oil pump and braided steel lines. Exhaust is done just needs bolted up, looks like i will fire it up on Tuesday!

I have very detailed pics of every piece that was fabricated for this build so yes I can and will post up pics of the airbox later this week.

Tim

Done!

Runs great! 6.5 psi boost @ 6500 rpm pulling 13 degrees timing air/ fuel was at 12.0 and it felt great! Going to run the existing fuel out, fill it with 100 octane and head for the dyno to see what difference all my work really made. Exhaust sounds fantastic!

So, you're blowing into the stock airbox, I see. I have found that the plastic airboxes leak like sieves. You may want to pressurize it to check. Do you have any backfire protection?

Nice work overall. You will be making a lot more than 240 at the wheels, I'm sure.

Air box

I am blowing thru the stock air box, i did have a few leaks but taken care of, my 1st goal was to get it up and running at 6.5 psi boost assuming the box would hold that kind of pressure with no problem. My backfire protection right now is a spare air box! I am in the process of fabricating a stainless air box which i can tig weld my lid to and be done. By the way i have no lag with this set up it spools very fast. Since 1st goal is met i will enjoy it this way hopefully all summer and next winter approve upon a few areas so i can turn the boost up.
Next goal 14psi!!
