Toyota 4AGE Bike throttle bodies kit 42mm danST STARTER PACK
danST Engineering are pleased to be able to offer this complete bolt on kit for the popular Toyota 4AGE engine. The package consists of the following:
1x TIG welded danST Engineering Aluminium inlet Manifold
1x Set of Tapered 42mm GSXR1000 throttle bodies, complete with injectors, fuel rail and TPS
1x danST Engineering Fitting Kit (4x Fluoro lined silicone hoses and 8x stainless mikalor clamps) in red, blue or black
50mm Diameter, danST Aluminium Trumpet Kit complete with custom danST clamp ring assemblies (trumpets available in 25/50/90mm lengths, please use drop down to select)
1 x Pipercross PX500 or PX600 filter kit (depending on space and trumpet requirements)
1 x danST Engineering Universal Throttle Linkage Kit (all parts to adapt your existing cable)
4 x Injector Plug Connectors for terminating the injector loom
This kit is ideal for anyone wanting to carry out the popular bike throttle body modification. Bike throttle bodies offer excellent performance, reliability and fuel economy without the pricetag normally associated with TB conversions! These conversions are very popular in both modified and kit car circles as well as Hillclimb and Motorsport applications and provide a low cost, simple power upgrade not to mention a fantastic soundtrack!
NOTE: A standalone mappable EFI ECU will be required to run this kit on your car (the standard ECU will not support individual throttle bodies). We can supply Motosport Electronics ME221 ECU and loom kits (as seen in the above video), please see our other shop items.
The manifold is manufactured from high quality aluminium with a precision Water Jet cut 10mm thick flange and TIG welded 51mm (Outside Dia) runners with a 3mm thick wall. All internal joints are fully ported/ground to ensure a smooth flow.
All danST supplied Throttle Bodies undergo a comprehensive inspection, strip, ultrasonic clean and rebuild process.
Kits can be customised to your requirements (eg delete the filter should you wish to utilise another solution). Buy these now and have your cars performance increased ready for the summer season! We can also supply the following additional items to aid your ITB conversion:
Standalone Engine Management ECU's (ME221) with relevant wiring looms
Various Sensors (crank position, air temp, water temp)
Data Cables
Please Note: All of our throttle body kits are made to order and therefore on a 10 working day lead time. This is to allow the manufacture of the manifold and preparation of the throttle bodies.
FAQ’s:
What Else Will I need?
1.0 Engine Management & Sensors.
To run any EFI system an ECU is required. We offer the same kit but with the ME221 ECU and associated loom and sensors under our 'Fast Road Pack' for this engine. A coilpack (typically a Ford wasted spark type) and matching ignition leads will also be required.
2.0 Fuel Supply
All danST Motorcycle Throttle Body kits come with the bike injectors and fuel rail included and require a typical EFI fuel supply pressure of 3 Bar (45psi).
2.1) OE Fuel Injected Engine. The standard fuel pump on a vehicle running EFI as standard will usually be sufficient to fuel an individual throttle body set-up (engine spec dependent). Should you opt to retain the OEM fuel rail, regulator and injectors then the fuel system will remain unchanged. If you opt to run the injectors in the throttle bodies then an aftermarket fuel pressure regulator will be required (offered as an option).
3.0 Throttle Linkage. The throttle cable connection is relatively simple on bike throttle bodies in comparison to other aftermarket offferings with no complicated linkages required. In most cases it is simply a case of adapting the end of the existing throttle cable (inner and outer) to interface with the carbs. Our throttle body kits come with the basic parts to achieve this adaptation, or the danST universal cable kit can be used to make a cable assembly up (see our shop for this kit).
4.0 Rolling Road Tune. Our throttle bodies are fully balanced prior to dispatch. However the ECU will need a mapping session using the necessary AFR equipment and under real world load conditions (usually on a rolling road). This will ensure the maximum performance is achieved and will avoid engine damage that can be associated with running excessively lean or rich.
What power increase will I see?
Power gains are highly dependent on other work carried out to the engine. As with any induction modifications the throttle body kits will better compliment an engine that has had an exhaust manifold and system upgrade as a minimum. Camshafts and headwork will of course further benefit the power and torque curves. A typical healthy 2.0 Ford Zetec (standard 135bhp) will see 165-170bhp with an ITB kit and free flowing exhaust when correctly mapped. Please also see the various customer power graphs posted on our website for typical examples.
How do I connect the fuel supply without a return on the fuel rail?
Please see the below fuel supply schematic diagram (swirl pot is optional):
