930 turbo transplant

[Ruff1]

I want to put an 1989 porsche 911 turbo motor into my 1973 911 is this a hard job and what bo i need? Will my stock tranny work and what about fuel pump and rear drive train?

It will work. What R&P ratio do you have? 73-75 was the changeover year, so you could have either depending on your build date. You might want to go to a 8:31 vs a 7:31 if you have that. What is in your car now? (engine/fuel setup?)

[slammed1000]

if you can get the fuel pumps,lines from the turbo car you shouldnt need much else. you can run a single aftermarket pump but if the fuel pumps come with the motor you are purchasing get them. if the car has a 7:31 trans you might want to try and find a later 8:31. i did one in a 69 a while back but we used the turbo trans also.

Please don't do this to a '73.

Thank you.

It will work but transmission will only hold up for mild driving. Mild driving will be hard to do with such setup.

You will need to change the length of the throttle rod at the throttle body; you will need extra oil cooling up front; you'll need a tail to clear the intercooler; you'll need to adapt the 14-pin harness on the 930 engine for the older car.

Then you'll have to get a second job to raise money for the EFI, G50 conversion, and rear flares.

it ain't fun unless it's dangerous. i would suggest selling your 73 trans and using a later aluminum 915. i had a 3.0 hotrod 930 in my 73 speedster conversion and it was awesome.
