2270cc RT Engine for Porsche 356 cars


Install MassIVe power without cutting or permanently modifying your 356. Using our specially configured 356 conversion engines; featuring our DTM cooling system and proprietary conversion flywheel, and clutch assembly you can convert to Raby power in just a single weekend.

Face it… the original engine in your 356 was designed so long ago that it doesn’t even feature camshaft bearing inserts! That means even a “VW Engine” is more technologically advanced!

  • Price includes Dyno optimization.
  • Customer Core required. If no core, add $2,500.00 (see Core Options)

  • The exceptionally fun to drive 2270RT uses the latest cylinder head offering, the RS+ to develop 140HP and 160 lb/ft of torque.
  • Specifically designed and tuned to best utilize the stock 741 transaxle without shredding it to bits! (4th gear ratio alterations recommended)
  • 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@ 5,200 RPM.
  • This is the largest engine that we’ll couple to a “stock” 741/ 356 transaxle as engines of greater output will shred the 741 due to the extreme torque.
  • We do offer regeared, altered transaxles to best optimize this engine package.
  • We can create an engine and transaxle package for you based on your core transaxle.
  • Big, usable, mild-mannered power are the best characteristics of this engine. With a touch of the throttle, the engine accelerates smoothly like a big diesel.
  • This engine comes complete with DTM V2 cooling system, 180 or 200mm Porsche 356conversion flywheel and etc and is 100% ready to install into any 356, no matter the year.
  • This engine can be special ordered to utilize stock 6 Volt electrics.

Pricing and Ordering

Prices for our Turn Key, complete Dyno Proven engines are posted at the top of each engine offering. Select an engine package from the navigation bar on the left side of your screen then see the pricing tab for the prices of that base engine; which most of the time even includes options. See also our Engine Wizard to create your own custom engine!

Anytime that something is “Custom built” you can typically expect to both pay more (initially) for the product and also receive more from it. There is no exception to this rule with our engines here at Aircooled Technology. Our engines are created with a Pedigree that follows them everywhere they go, all over the world.

You will not find any other Engine Builder in this industry that does business the way that we do. Here we work from a Proposal basis from very specific documents that will outline the entire build and it’s cost from the very beginning. I conduct business the old fashioned way meaning I’m point blank and I’m both fair and firm. Some customers that are accustomed to today’s modern ways of doing business are taken aback by my direct way of getting to the point and getting the job done. None of them regret spending their hard earned money with my company or having me create their engine..

Here I do not believe in fine print or grey areas in contracts or misleading people with misrepresentations of what I can do for them. I try my best to be open with the customer from the first phone call all the way till the time they drive the car for the first time.

If you want my engine I will sell it to you, not someone that gets paid a commission because he is a smooth talker. As the Founder of this company I have personally sold every aircooled engine that we have created; and that will never change.

For a current price for your base engine, please see the list of applications for your vehicle, then follow those links to the detailed information which includes a general price. You can also use our Engine Wizard to build up the engine of your dreams. For all other requests please contact my Director of Operations, Jud Fink by submitting a support ticket. Jud will set you with me for all details.
