Product Description

This Blow Off, or dump valve, is for the Renault and Nissan Turbo engines that have the electronically controlled bypass valve (OEM Part no. 144839204R). It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred. Unfortunately, the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this. This prevents the diaphragm from sealing.

Our alternative is a fully engineered solution offering both significantly improved reliability. The Forge valve is piston based, there is no diaphragm to fail, and of all aluminium billet construction, it replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control, over valve actuation.

In The Box:

  • 1 x FMDV23A Valve
  • 1 x 2000mm of 4mm Vacuum Tube
  • 1 x 50mm of 10mm Vacuum Tube
  • 1 x 3 port Solenoid and fixings
  • 13 x Cable Ties
  • 1 x Uprated Red Spring
  • 1 x 10-6-10 T Piece
  • 1 x Forge USB Instructions
  • 1 x Forge Keyring and Sticker

If you wish to tune this product to fit the needs of your engine, please see the spring tuning kit below.

Compatible Vehicles

Note that the models listed here have either had the part fitted by us or a customer or they are listed as being compatible on industry parts databases. Where it has not been directly fitted by Forge there will then be a separate May Also Fit tab where the make and model will also appear and which details our no-risk approach to purchasing this product, so it is worth checking there as well.

Warranty Information

The majority of Forge Motorsport products come with a limited lifetime warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.

This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
