This is the original version of the engine that we created especially for the more demanding 914 driver that likes a better performing “Dual Purpose” engine/car- It’s the 2316 and it is very fun to drive!

This is the “Aircooled Technology” "2316 original Annihilator" base engine it was developed in 2001 and currently is being refined to create another base engine that is even more performance minded. This engine is unique in its ability to absolutely haul ass and still remain tractable in traffic and still have a somewhat smooth, slightly choppy idle.

This engine is built with performance in mind. We did not go to extremes when designing it to have great fuel economy, or a 100,000 mile life span. This engine is for the 914 driver that likes torque as well as high RPM capability as it will spin to 7,500 RPM easily.

The 914 needs torque to get up and moving, but to really perform better at any level it needs added RPM power. This engine has that and plenty of it. In my personal car that you can read about here.  The engine performed flawlessly and really amazed many passengers. On many occasions just taking someone for a ride in this car was enough to sell them on the 2316 combination for their own 914!

The 2316 has been refined many times since this early edition of its creation and has progressively gotten better and better. The powerband of this engine comes on hard at around 4,000 RPM and shoots quickly to redline at 7,500. Some versions of this engine with our severe duty valve train retain valve control to 8,000 RPM and make monstrous track engines that are still street drivable on pump gas. This engine has incredible midrange and top end power and coupled with the 914 gearbox it can achieve 100MPH in just 3rd gear with stock gearing! With its shorter rods and longer stroke this engine spins up fast and achieves RPM incredibly. The cylinder heads that we have designed to work with this engine match it perfectly and have high port velocities that also promote rapid acceleration while allowing for smooth power transitions on the street.

The demand this engine has for exhaust is high and a normal set of heater boxes won’t cut it! This engine must use headers and we highly recommend the Tangerine Super Header to compliment this combination as it was used with great results on our original test engine. If this engine is not outfitted with good exhaust expect drastic power drops and hotter running temperatures- not good.

Speaking of HP keep this in mind. The Six cylinder 911”SC” us-49 state engine produced 180HP@5500 and 175Lb/Ft of torque @4200RPM! This SIX cylinder engine is heavier than your 4 cylinder 2316 that virtually equals the HP and Torque for LESS MONEY!

If you want a more powerful engine that still has a 60-70,000 mile lifespan this 2316 engine may be for you, especially if you like a durable engine and don’t mind spending some extra money on your go fast hobby. Since this engine has more severe duty parts it does cost more but after it’s all said and done the durability and even reliability make the purchase of this engine really worth it- not to mention the power.

The cooling of this engine can be accomplished with the stock system, but due to its power output this engine will benefit from our 914 version of our DTM very well. A cooler engine makes more HP and lasts longer so the perfect annihilator” would be DTM cooled for sure!

Currently we are working on a Fuel injected version of this engine and will update the site when the developments are made. When this engine is completed look for more bottom end power and even more HP at all RPM ranges due to increased efficiency!

For those who want a more tame engine that isn’t quite as powerful we also offer a detuned version of the “Annihilator” that is just as smooth and torque filled as our 2270cc “Performer” but just has more power and is easier to drive with a lower redline. You can see its graph below as well for comparison.

The Annihilator is a very serious engine combination that was designed especially for the 914 on Steroids. We highly recommend this engine for the serious driver who likes to push his car to the limit and we know from experience in my own car that it will take the constant abuse like a champ.

With our dyno tuning you can rest assured that the engine will arrive in the best state of tune possible and producing its peak amount of power with its best settings for the desired RPM. Each of these engines is balanced much better than stock to a tolerance of “Intermediate”, and benefits from all the same procedures as our larger more powerful engines, even dyno tuning. This engine is best if built from a customer’s 2.0 core, but we can start with any core, or even supply a core if need be.

The future “Annihilator” owner will expect to see 18-20MPG, zero-60 times increase drastically and top end performance to far out perform the capability of some complete cars! This is a serious engine, with a serious goal and it means business. I have owned one of these and can honestly say that it scared me on many occasions and that simply doesn’t happen!

Unlike many of our other base engines we are sharing multiple graphs from some of the various states of tune that the 2316 can be made into. If you are interested in 2316 power we’ll help you choose what you need and one thing is for sure- You’ll haul ass and LOVE IT!

NOTE: This engine IS NOT compatible with the stock EFI system! It is designed as a base for those who want to add our Aftermarket EFI system to their engine, or outfit it with carburetors. We have a base version of this engine for each of these methods of fuel delivery.

Graphs coming soon...
