Porsche 912

Porsche 912 and the TIV
Create your own “912E” with your early 912!

The Porsche 912 is a great vintage vehicle, and has sufficient power to keep up with today’s traffic in most instances. The cars handle great, but are a tad bit heavier than the earlier 356 which shares virtually the same engine.

The 912 shares one major con in the engine department with the 356, and that’s with cost Vs. Horsepower and reliability. We do 356/912 engine rebuilds and have some of them posted on from doing these engines in the past, we know how difficult it is to find quality parts at a good price. Due to the high priced hard to get engine parts, it is not uncommon for a stock 356/912 engine to cost over 7-8,000.00 to be done right.

Enter the 4th dimension- Add TIV power to your 912

Porsche chose the VW TIV engine for use in the 914 and 912E!

Yes, you heard right……it is possible to install a VW Type 4 engine into your 356 for LESS than rebuilding your stock engine! Our MassIVe DTM converts the “Pancake style” TIV engine to an upright engine, and allows the install quickly and easily! With the 912 you have an engine bay that will accommodate a 6 cylinder engine. With that comes the possibility of installing a TIV engine in its original pancake state, and having it look like a factory 912E, which shared the same engine, the TIV. If you choose to do the conversion with our upright kit, you will gain efficiency, and ease of maintenance. If you want to keep the engine a “pancake” we can provide you with the appropriate conversion pieces and do so with no guesswork.

Imagine having 150 BHP of reliable performance at the turn of the ignition. You can have your cake and eat it too! And all for less or equal the cost of rebuilding your stock engine. Heck, its even possible with the TIV engine to install air conditioning to that same engine, and never know it’s turned on!

With a TIV powerplant of any size you can enjoy tremendous torque, and excellent fuel economy, while keeping super reliability! Choosing TIV power for the 356/912 is a wise move in every direction, from reliability to parts acquisition to cost and every other aspect.

Here are the facts….

With our MassIVe DTM cooling system it is possible to remove your stock engine, in its entirety. The stock engine can be stored for originality purposes, so when you sale the car you have maintained its originality. When fitting the TIV powerplant you will not need any of the stock 356/912 engine parts for the conversion, so your original engine can be put in safe keeping for later

The TIV engine with the MassIVe DTM cooling system and our conversion modified flywheel will slide directly into your 356 gearbox. The installation also DOES NOT REQUIRE ANY CUTTING OF YOUR 912 OR MACHINING OF THE TIV ENGINE!!!

When the TIV is converted with a MassIVe DTM shroud this is the end result- A reliably powerful engine! If you want a stock TIV engine making 80 BHP, or one of our complete MassIVe conversion engines from that can make 160BHP with a few modifications and a dose of our “attention”……You will not be disappointed either way. With the TIV added displacement does not cost reliability or longevity decreases when done the correct way with a proven recipe.

The TIV engine (of pretty much any displacement) is great in town, or on the highway, so the character of the 356 is enhanced by the addition of the “Factory Big Block” The Type IV!

Being able to have a 100(stock HP)-150BHP(performance,2270cc) engine that idles like stock in town and gets 30 MPG, while having a rev capability of 7,000RPM (with performance engines) is absolutely amazing. It really pushes the 912 at any speed, and power is virtually on demand with the vehicles gearing.

The MassIVe DTM shroud installs onto the engine quickly and easily. This is especially true if you opt for our deluxe kit with all new TI cooling parts and our water-jet cut sheet aluminum air sealing kit. We have a sealing air tin cut made especially for the 912 conversion, this makes the job A cinch, and so easy!

The installation of the engine into your vehicle is easy, it installs just like a standard 912 engine, in most cases can be done in about the same amount of time. The 912 has a larger engine bay and the engine will slip right in, with NO CLEARANCE ISSUES.

Currently there are only a few exhaust systems for the TIV conversion. We are working on getting several of these imported and offering them as well. These exhaust systems do not incorporate standard heater boxes and fan shroud pressurized air for heat delivery are more difficult to arrange with a TIV conversion. The best method of updating your heating system is with a “Gas heater”. These were original equipment on many VWs and we keep a few of them around to sell most of the time.

The conversion engine will need to be fitted with Dual Carburetors, or a Fuel injection system that uses twin throttle bodies with hex bar linkage. The design of the shroud does not allow the use of a single carburetor. Single carburetors on large engines like the TIV have been proven to be inefficient, so this is not an issue with most conversion enthusiasts. With a set of conversion manifolds and linkage you can keep your stock Zenith or Solex carburetors for the conversion engine!!

One of the best parts of our cooling system is that the engine does not look like a 911, or a TI, it looks like something many people have never seen, and that will separate you at car shows and events. The MassIVe DTM has a hint of a nostalgic look, and some people will confuse it with the factory 356/912 engine. I have even had folks think that a converted engine was a 547- 4 Cammer!!! (AKA Carrera engine)

If you currently own a 912E, our shroud will also install easily to your current engine, and will provide better cooling and ease of maintenance!!

Of course, if you desire your conversion engine to be designed, balanced, blueprinted assembled and thoroughly dyno tested by a professional, then see our complete conversion engines on our sister site Do it all once and forget it!

With our shroud and a TIV the engine won’t be needing much more than a wipe down, because it simply won’t be breaking any longer- It’s a TIV!

So in one sentence I’ll sum it up…

Add 40-50BHP to your 912, do it easily, and do it for the same or less than rebuilding the factory engine to stock Specifications!

I Love 912s, and I Love my 912E…..make your car a 912E and do what I do with mine….drive it 30,000 miles in one year and only open the decklid to show off what you have got, that “THEY” don’t!
