Porsche Speedster Replicas

The Porsche speedster is a very sleek, sporty, vintage Porsche Replica- It Looks FAST. It deserves the power to motivate down the road, for thousands of miles, and do so without constant maintenance.

Many replicar owners are not super handy with tools, so they need an entire vehicle that is trouble free. They also need an engine to propel that vehicle that also is trouble free. When the TIV is converted with a MassIVe DTM shroud this is the end result- A reliably powerful engine!

The Speedster is a great car for getting around town in, as well as jumping on the freeway and making a trip to a car show or other event. The TIV engine (of pretty much any displacement) is great in town, or on the highway, so the character of the speedster 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 speedster at any speed, and power is virtually on demand with the Speedster’s lightweight body and chassis.

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.

If your Speedster is outfitted with a transaxle prior 1971 you will only need 3 later model pieces (release bearing, clutch cross shaft, and a release bearing guide, all of which we sell in a kit just for this) to bolt the TIV engine to your current gearbox. If you have a post 1971 gearbox no conversion pieces are needed and the engine is a direct bolt up. The TIV engine will bolt to either a swing axle or IRS chassis. Some conversion enthusiasts opt for one of our conversion gearboxes that’s 100% set up for the TIV engine and is ready to install. This gives better fuel economy and better torque transfer with the now larger engine. We design the gearbox for you and your cars powerplant.

The installation of the engine into your vehicle is easy, it installs just like a standard Type 1 engine with dual carburetors and in most cases can be done in about the same amount of time. The Speedster 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.

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 speedster engine. I have even had folks think that a converted engine was a 547- 4 Cammer!!! (AKA Carrera engine)

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!

Of all the conversions we have done, The speedster is one of my favorite cars.They really turn heads wherever you go. If you have a Speedster (any Manufacture) and want to boost the daily drivability or all around performance, choose the Type IV for the job and you will be amazed. 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!
