Megan Racing SR20DET Manifold

Stainless steel turbo exhaust manifold to fit the SR20DET. This is a copy to name brand bottom mount style tubular manifold and is excellent value for the money. Built from 2.8mm thick wall schedule 40 stainless pipe, this manifold will help to scavenge turbo exhaust gasses and help produce faster boost and more hp. Fits all T15, GT25, GT28 series turbos with internal wastegates for the SR20DET. - 100% 304 Stainless steel - 2.8mm wall thickness - 0.5" flange thickness - Includes bolts and gaskets - Fits SR20DET motor

- 1 year Megan Racing warranty included

Note: Contrary to the popular belief that these and other Ebay manifolds crack easily, it's true that ALL stainless manifolds will expand and move more than factory cast manifolds or mild steel S40 manifolds, so exhaust mounting and engine and drivetrain vibration all attribute to stainless manifolds cracking prematurely. We have testimony from many customers that have had this manifold for years with no issues on cracking. Ensure that your engine and transmission mounts have been replaced, along with PROPERLY hanging your exhaust system and turbocharger. Excessively loose exhausts will pry on the manifold and cause it to crack. Replace or reinforce all exhaust hangers especially the main one that comes off the transmission. We at PDM see more of these hangers broken off or exhausts hanging loosely which cause more exhaust leaks and cracked headers and manifolds.

Megan Racing Stainless 70mm Turbo Elbow for SR20DET

70mm turbine outlet elbow for stock SR20DET turbo, or stock replacement turbos. This elbow also fits Trust T517Z/T518Z Turbos. Reduces turbo lag with noticeable torque improvements throughout the entire powerband, with boost kicking in at lower rpms.

Made from fully tig welded and polished 304 stainless steel, the Megan kit contains all the necessary bolts and gaskets for a direct fit. Plus this unit just looks so much better than the rusty red stock manifold. A perfect addition to the Megan SR20DET exhaust manifold.

DC Sports 4-2-1 header systems are dyno tested to outperform all comparable header systems on the market. Extensive research and development goes into each system to ensure the best performance for your vehicle.

DC Sports header systems are precision bent on CNC mandrel benders using data acquired from their non-contact digitizing scanner. All flanges are CNC machined, then machine-grind the flange-mating surface to ensure a leak-free seal, and a robotic welder is used to attach the flange to the header pipes. This state-of-the-art manufacturing process ensures superior quality and a perfect fit with every header system DC Sports make.

DC Sports headers from PDM are available in mild steel with a proprietary temperature- and corrosion-resistant ceramic coating. After manufacturing, they are subjected to a thermal degrease and a preliminary sandblast to prepare the header's surface for coating adhesion. Every ceramic-coated system is hand-painted to ensure an even application of coating. After verifying the proper thickness of the coating, the header is cured for proper bonding of the ceramic coating and then fine-blasted for a high-luster finish.

DC Sports 240SX headers are designed to produce maximum power and torque from your DOHC KA motor. 4 into 2 into 1 design maximizes the KA’s pulse signals and allows for a design that provides maximum ground clearance and emphasizes low- to mid-range power for street/drag/drift and auto-x.

Greddy has been an industry leader in turbo car accessories, and PDM has a soft spot for their products. The type RS Blow Off Valve (BOV) was created to be an extremely reliable blow off valve with a very compact design. Improved response and increased pressure are achieved through carefully selected spring rates and a large 40mm valve. With it’s unique CNC machined 8 discharge ports in the horn, this BOV draws air from the surrounding atmosphere to really increase the blow-off sound. The Type-RS is compatible with the standard GReddy Blow-off Valve flanges.

Features:

- 8 discharge ports that draw in surrounding air and release a unique discharge sound.
- 40mm hard-anodized valve for increased airflow.
- High-quality diaphragm and short stroke significantly increase response.
- allows for high boost pressures due to the Type-RS’s dual spring system, which promotes increased response
- Optional discharge adapters for rerouting discharged air back into the intake charge (not included)
- Utilizes same flange as older S and R valves, so installation is simple retrofit.

• 347 Stainless Steel Alloy is used for valve and valve housing.
• High temperature silicone Nomex reinforced actuator diaphragm.
• 17-7 PH Stainless Steel actuator spring gives consistent pressure at high temperature, resists "relaxing" at temperature to 900F (483C).
• Nitronic 60 Stainless Steel is used for the valve seat and the valve bushing uses the same material found in the higher level gates for reliability and longevity.
• CNC Machined 304L 12mm thick weld flanges.
• Available spring pressure: .25Bar (3.63 psi), .4Bar (5.80 psi), .5Bar (7.25 psi), .6Bar (8.70 psi), .7Bar (10.15 psi), .8Bar (11.60psi), .9Bar (13.05 psi), 1.0Bar (14.50 psi)
• High Pressure available: 1.1Bar (15.95 psi), 1.2Bar (17.40 psi), 1.3Bar (18.85 psi), 1.4Bar (20.30 psi), 1.5Bar (21.75 psi), 1.6Bar (23.20 psi)
• Comes with gasket and vacuum hardware. Stainless flanges are NOT included and sold separately.

Comes standard with a 1 bar spring. Other spring pressures available if needed, call for details. This is the wastegate we are using on the PDM Racing turbo KADET with huge success. Note if you are plumbing your wastegate back into your downpipe, we recommend the stainless flanges and flex pipes sold below to custom build your wastegate pipe. Also we recommend drilling and wiring the bolts for your wastegate to prevent them from coming loose under repeated heat cycles.

Vibrant 1.5” wastegate flexible exhaust tube

If you plan to plumb your wastegate exhaust back into the main downpipe, you must use a flexible piece inline with the wastegate tube to prevent the tube from cracking. Since exhaust gases are only going through the wastegate occasionally, the temperature difference between the main downpipe and the wastegate pipe is extreme, and these two pipes will have different expansion rates. To allow flex in the “cooler” wastegate tube, you must use a flexible joint to allow for variances in the expansion.

Stainless 1.5” flex piping manufactured by Vibrant is your solution. Inner stainless coil wound tubing with outer stainless steel flex hose, this exhaust tube can be tig or mig welded inline with your wastegate to allow for flex and movement between the main turbo downpipe and the wastegate. An absolute must.

Silicone connectors

3" silicone rubber connectors, and 3" to 2.5" reducers to adapt to your MAS. Building your own cold air intake for your naturally aspirated car ? PDM offers silicone rubber adapters to allow you to build your own systems. These are inexpensive couplers and reducers to allow you to install air filters and intake extensions for your intake system. (note, these are not designed to withstand heat or boost, so they are not for turbo hot pipes or intercooler pipes)

300zx MAS

Nissan's MAS system is a highly efficient extremely accurate method of monitoring intake air flow and works flawlessly through all temperatures and vehicle loads. However, the stock KA or SR MAS is calibrated for only so much air flow. Boosted KAs and modified SR owners that run much larger turbos and boost numbers 2 -3 times higher than factory numbers will soon run out of MAS airflow capacity. One of the most common, and effective upgrades is changing to the 300zx Z32 MAS. This unit is designed for airflows for the turbo-charged 300zx with horsepower airflows in excess of 500+ hp and is a perfect upgrade for SR and KA-T owners.

Note: ECU will require reprogramming to compensate for larger MAS (contact PDM for ECU upgrades).

Z32 300zx MAS adapter

Z32 MAS plug similar to the Tomei units with matching wiring colors for SR MAS engine harness for color matching install. The extra 'solid brown' color wire is for chassis ground.
