Porsche 912 2270 SR/912


The Porsche 912 is a great vehicle to outfit with one of our MassIVe engines! The appeal of the 912 suggests that it’s a 911, but the engine just doesn’t do it all the justice it deserves.
Here at Aircooled Technology we do not offer engines based on the original Porsche 616 “912” engine. Our focus is on the application of the Porsche 914/4 engine featuring some conversion and efficiency boosts that allow it to easily be BOLTED IN to your pre-1969 Porsche 912 with no modification to the vehicle.
The reality is that in the modern world we can provide a 150HP 914/4 based performance engine outfitted for daily service and reliability for the same cost or less than a 90HP 616 engine! The conversion is carried out with a mix of VW, Porsche and Aircooled Technology specific components.
The wise 912 owner will realize that he can pull the original 616 engine thats tired and in need of a 10-14K stock low HP high dollar rebuild and “pickle it” for a later date when the car is more valuable with it’s original, matching numbers engine. This is capable with a Raby conversion engine as NONE of the 616 engine components are necessary for the MassIVe engine conversion.

2270 RT and other motors. Product Options:


  • Rated at 155 BHP with 170 lb/ft of torque this is my favorite engine combination for any application, but it really shines in the 912.
  • 2270 SR/912 uses a high-velocity intake port cylinder head offering, the RS+ to develop 155HP and 170 lb/ft of torque.
  • This engine’s power band is exceptional as it pulls from 2,000 RPM to just over 6,000 RPM with ease, making peak HP@ 6,200 RPM.
  • Over and over again this engine astounds me with it’s extreme drivability and manners while making big, usable power.
  • This engine comes complete with DTM V2 cooling system, conversion flywheel and etc and is 100% ready to install into any 616/ 912 engine bay through 1969.
  • Pull your original engine and preserve it; the 2270 SR needs nothing from your original engine except the mount bar!
  • All 912 conversion engines require rear engine hangar fabrication during installation
  • Optimized drivetrains will take advantage of MassIVe Type 4 power through altering the OEM gear ratios to take better advantage of the high torque output of the Type 4 engine.
