Fits:
Porsche 911 2.0ltr - 1965 to 1969 
Porsche 911 2.2ltr - 1970 to 1971

This distributor is made in the historical design of the original Magneti Marelli ignition distributor and combines the latest technology with an authentic look. 

It was installed at the factory on the 906, 911R, 914/6 GT and 911 ST and the ignition map is easily and freely programmable via an app and Bluetooth. 

In addition, an immobilizer can be locked/unlocked with a PIN and a speed limiter can also be set easily via a smartphone. 

This version requires two 3-pin HKZ devices but it fits all engines from 1965 to 1971, so from the 2.0ltr to the 2.2ltr

Rennline RSR Style Stainless Steel Engine Carrier.



Fits:
Porsche 911/930 1965-89 Coupe And Targa
Porsche 964 Turbo 1990-93*

Adding solid or semi-solid motor mounts is a very popular upgrade for any 911 that is driven the way it was intended to be. Unfortunately the factory mild steel engine carrier is very weak and flexable, defeating the purpose of upgraded mounts. Rennline's RSR Style stainless steel engine carrier eliminates that flex due to its upper and lower horizontal flanges replicating those on the factory RSR race cars. Additionally, the Rennline mount incorporates gusseted mounting points built to withstand extreme horsepower and race abuse. This engine mount is by far the strongest engine brace on the market today.

* 964 Turbo's will require aftermarket or RS engine mounts with m12x1.5 threaded bolt.

Rennline Tunable Semi-Solid Engine Mount (Pair).



Fits:
Porsche 911/930

The Rennline Tunable Engine Mount for the 911/930 offers the ultimate in adjustability for your car. Replacing your compliant factory mounts will decrease engine movement resulting in better acceleration, handling and significantly increased shifter feel. This is the ultimate solution for almost any car, and allows you to tune our mounts for the way you drive. Our mounts are CNC machined from billet aluminum and include three pairs of inserts in varying densities. Tune your mounts by using the softer inserts to reduce engine slop and avoid missed shifts in your street car, or utilize the stiffest inserts to get the most from a more focused track car. You can even mix and match, giving you 9 possible combinations to let you dial in our mount to your specifications. Here at Rennline we know you want your Porsche to be flawless, and that is why we are Driven to Improve Excellence.

Lightened crankshaft for steel con rods. 



Fits:
Porsche 911 2.0ltr - 1965 to 1969
Porsche 911 2.2ltr - 1970 to 1971

Notes
Conforms to FIA Appendix K
Tested to 10,000 RPM

Increasing the performance of an engine via the crankshaft does not make sense at first glance, but it is worth taking a closer look. 

The mechanical efficiency of an engine, which, together with the thermodynamic efficiency and the volumetric efficiency, determines the rated output of an engine, depends fundamentally on the diameter of the crankshaft bearings and the friction in the bearings. 

Of course, the diameter cannot be easily changed, but the friction can, which in turn depends on the bending loads and the resulting vibrations of the crankshaft. This is exactly why the use of top-quality titanium connecting rods is of little use if the resulting significantly reduced rotating masses at the connecting rod foot are not also taken into account on the counterweight side of the crankshaft. 

Because only a perfectly designed crankshaft, calculated for the connecting rod weights, actually brings with it less bearing friction due to eliminated vibrations, and thus an increase in performance. Furthermore, this crankshaft is speed-resistant up to 11,000 rpm and tested in continuous operation up to 10,000 rpm. A pleasant side effect is of course a reduced load on the crankcase and less wear. 

This crankshaft is designed utilising the latest calculation methods using CAD and FE methods (finite elements), but is still FIA legal for historic motorsport and conforms to Annex K, but is only designed for operation with steel connecting rods. The focus was on the FIA ​​regulation that " in the case of a new production, the original or the newly manufactured component may be lightened, which was exactly the case with this crankshaft. 

If you want to run this crankshaft with titanium connecting rods, use crankshaft part number 91610201600/1 which is designed for the lower rotating masses of titanium connecting rods. Failure to comply with the mass balance will sooner or later lead to the crankshaft breaking at maximum speeds. 

Furthermore, this crankshaft is an authentic replacement for every standard crankshaft of the 911 from 1965 to 1971, i.e. every 2.0ltr and 2.2ltr engine.

Oil Inlet Check Valves eliminate oil migration from the oil tank to the engine reducing excessive smoking on start up typical of cars that sit for long periods of time.



Fits:
Porsche 911 1965-71

For freshly rebuilt engines, do not install check valve until first oil change.
Before installing, start your engine and verify/ reference your oil pressure. Drain oil from the engine and oil tank. Remove the rubber oil inlet hose on the right side of the engine directly behind the #6 cylinder. Cut a 1.5" piece out of the center of the horizontal section of the hose. Install the check valve with the correct orientation and tighten the clamps. Reinstall the hose and refill engine oil.
Check your oil pressure gauge when you start your engine and verify pressure.
Note: the valve is clearly marked with an engine side and a tank side. Failure to install the check valve in the right orientation will cause oil starvation and catastrophic damage to your engine.

Rennline Stainless Steel Alternator Strap.

Fits:
Porsche 911/930 All 1965-89

We have redesigned our alternator straps for a sleeker look and simpler install. On most older 911's, the cadmium-plated alternator housing strap looks worse for the wear - the plating has become dull or corroded. The factory alternator housing strap can't be replaced without removing the ignition distributor, which necessitates resetting the engine's timing. Rennline's new alternator housing strap solves both problems: the brushed stainless steel perforated strap can be left as is or painted the color of your choice, and its unique 3 piece design makes installation easy to accomplish without touching the distributor. Comes with stainless steel hardware.
