There has been all kinds of engine swaps into the Base 914s (Porsche Aircooled 6 cyls-2.0L 2.2L 2.4L 2.7L 3.0L 3.2L 3.6L) along with a large range of Subaru Conversions and LS1 engines, SBC, any other conversions, along with 2056 builds etc. I’m sure a lot of people besides myself would like to see some performance specs after these conversions were completed (0-60mph 0-100mph, 1/4 mile, roll on performance) along with transmission changes and estimated cost for conversion.
Example: Upgraded to 2056cc build (Fats Performance), 125-130hp, dual 40 carbs, cam etc., headers, stock 901 side shift trans. With Rennshift Shifter, 911 suspension conversion. 0-60 6.5 seconds. 1/4 mile about 90 mph. Cost for drivetrain including trans rebuilt approx $10,000.00 in 2015. |

Went from a tired "Question Liter" Type IV (probably 1.7 or 1911) to a 2.2 "S" with Solex cams, a little head work, carbs, crankfire, headers, and a sport muffler. Suspect it was a wheezy 70-80hp on a good day, now 169.9 at the rear wheels unfiltered, and probably 160~ with a Fabspeed intake and filter in place (the snorkel was -20 hp, while deleting the snorkel and filter gained 12 back). So probably 180-190 hp. More than I had hoped for from 2.2 liters, and plenty for a narrow 914 (for me).
It's a different car, with more options more of the time and real oomph. But the real gain has been aural—with echoes of Le Mans/Targa Florio/Spa circa 1970 everywhere you go. You can drive it loud, or mellow, too. I do miss the more casual/tossable handling with the Type IV from time to time, but prefer the car overall with the six. Have always thought there's huge potential in the "outlaw" conversions, from various V6s and V8s to Mazda Wankels or Subaru flat fours and sixes. |
