Porsche 911 991 Engine & Turbocharging

This larger turbo inlet elbow is strongly recommend for use with the M660, Pure 700, and M800 turbos. The factory inlet elbows are place an unnecessarily high restriction upon the inlet of the larger turbos, and they don't fit correctly to the inlet of the turbo, due to the larger, machined opening.

These inlets will allow the compressor inlet of the turbo to breathe properly.

Note: The original part was 3D printed aluminum. However, due to supply issues, the updated part is nylon.

Product Details

The Flat 6 Motorsports by EVOMS Performance Diverter Valves replace the cheap OEM plastic diverter valves that are prone to leaking boost with tuned and even stock 911s. Flat 6 Motorsports has partnered with Evolution Motorsports (EVOMS), a renowned Porsche tuning company to offer a high-quality diverter valve solution. We leveraged their expertise in tuning high powered Porsche vehicles for decades. Paired with precision manufacturing, these diverter valves are built to last.

The performance diverter valves use a 100% 6061-T6 aircraft-grade aluminum housing with an engineered spring rate capable of handling higher boost applications. These performance diverter valves will hold consistent boost pressure, maximizing power delivery along with much quicker recovery, enabling faster acceleration and smoother rapid shifts from the PDK.

For any 991.2 Carrera running a tune, these are a must-have!

Features

Quicker turbo spool up
Faster transition between gears
Holds higher boost levels where the factory diverter valves fail
6061-T6 billet aluminum construction
Tested on 700HP+ 991.2 Carrera
Installation

The diverter valves are 100% bolt-on and installation can occur in a few hours.

Upgraded aluminum intake piping for the 991.2 3.0T Carrera / T / S / GTS

These extensions may be necessary on cars which have both an upgraded intake as well as a taller diverter valve (such as the EvoMS).

These will require some 6mm nuts and bolts to attach to the car (8 of each) which are not provided.

Need to install a 105mm rear main seal into a 991 or a 997.2 Porsche 911? Make sure you set the seal to the proper 7mm depth from the surface of the crank flange! If you install the seal without a tool that controls the depth, you'll likely install it too deep, and you'll have a high risk of a leaking seal.  It's simply too time consuming to do the job twice, so do it right the first time!

This is an affordable alternative to the costly (~$400) factory tool from Porsche. Simply bolt this tool to the crank using the flywheel bolts until the tool bottoms out on the crank. Remove the bolts, verify that your depth is even, and you're done!

This CAD designed tool is 3D printed plastic, and is safe to use on your seal without risk of damaging it or the bore that the seal sits in.

These turbos by Tial are a bolt-on upgrade replacement for the factory turbos. Capable of 650-770whp. These are an upgrade for all of the 991.2 3.0L turbo motors including the Carrera, Carrera T, Carrera S, and Carrera GTS.

These are brand new turbochargers and do not require your cores to be sent in. 

You will receive a refund for your cores of $2000 for a functioning K03 Turbo (from a Carrera/T/S) or $2600 for a functioning K04 Turbo (from a GTS).

Intercooler Upgrade Kit for 991.2 3.0L Carrera / S / T / GTS

Recommended for tuned cars with upgraded power. Compatible with all stock frame turbos, including base, S, GTS, M660, M800, etc.

Includes intercooler kit only. Product photo shows all turbo products from Tial.

The panel / cylindrical air filter is commonly referred to as "replacement air filter". It is installed in the vehicle's original airbox to replace the OEM air filter. It is made of highly performing materials that allow an increased air flow combined with a more efficient filtration, guaranteeing containment of all impurities from as small as 7 microns (compared to OEM's 10 microns).

This chart has a pure illustrative purpose and does not refer to the present filter.

BMC air filters are produced using a "Full Moulding" system that enables the characteristic red filter to be realized from a single mould with no welded joints thus avoiding easy breakage. The rubber used in BMC air filtering systems has a long life, is very durable and has optimum adhesion characteristics to all shapes of airboxes.

BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity.

All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit.

AMS Performance Intercooler System for 991.2 Porsche 911 Carrera

The Alpha Performance Porsche 991.2 Intercooler System utilizes a pair of 120mm thick high volume cores, smooth cast aluminum end tanks, and organically shaped carbon fiber ducts giving you the best cooling upgrade on the market. Each high quality Garrett core provides optimum fin density for unmatched cooling.

AMS developed the Alpha Performance Porsche 991.2 Intercooler System to provide you the best cooling upgrade for your Porsche 991.2 Carrera. In bringing these intercoolers to market our goal was to provide the ultimate system in terms of quality, simplicity, fitment, aesthetic design, and performance.

The Highest Quality Garrett© Intercoolers For Your Porsche 991.2

• The Alpha 991.2 Intercooler System utilizes Garrett Intercooler cores that are 50% thicker than OEM! Alpha’s massive cores give you the most power producing intercooler upgrade on the market by way of significantly cooling the charged air flow. Each of the two super thick 120mm Garrett© cores provide an optimum fin density of 20 fins per inch for unmatched cooling.
• AMS’ engineering team designed the Alpha 991.2 Intercooler end tanks with extremely smooth features and the perfect geometry for the best flow resulting in maximum horsepower. Designed using Solidworks 3D CAD software, these end tanks have improved flow over boxy sheet metal end tanks found on other intercoolers. They then took it one step further. AMS Engineers designed the organically shaped carbon fiber ducting to make use of every millimeter of available space for the ultimate power producing charge of cool air. The organic carbon fiber lower ducts allow the heat to transfer to atmosphere instead of soaking into the intercoolers.

Cooler Intake Charge Boosts Power And Response

• Channeling cool air to the intercoolers is vital for optimum performance of any intercooler. Some manufacturers choose to remove the factory intercooler inlets in order to cut costs. This greatly reduces the effectiveness of ANY intercooler whether it’s larger or not. Others require that you cut up and tape the factory shrouding to the intercooler core in an attempt to seal the shroud to the intercooler core. While this is better than removing the shroud, it is still not the most effective way to boost performance. The Alpha Performance Intercooler kit requires no drilling and no cutting.
• The Alpha 991.2 Intercooler System retains full use of the stock intercooler inlets forcing cool air into our larger, carbon fiber shrouds. Not only is this option more aesthetically pleasing, each rigid OEM-quality carbon fiber piece is made to seamlessly mate to the Alpha Intercoolers feeding them cooler ambient air more efficiently than the alternatives. Not to mention, eliminating the removal or destruction of your intercooler ducting. Included with the kit are velcro Alpha branded “speed straps” that hold the lower duct securely to the upper duct that will not deteriorate over time.

Maximum Airflow For Maximum Horsepower And Torque

• Perhaps the best feature about this intercooler system is that it maintains cooling efficiency as more Alpha Performance power producing upgrades are developed for your Porsche 991.2. It improves the effectiveness of your other upgrades giving you maximum hp output potential.
