Vauxhall C20XE 'Redtop' Bike Carb Conversion Kit

danST Engineering are pleased to be able to offer this complete bolt on kit for the Vauxhall Redtop C20XE Engine. The package consists of the following:

1x TIG welded danST Engineering Aluminium inlet Manifold c/w Inlet Gasket

1x Set of 37mm Mikuni/keihen Carburettors

1x danST Engineering Carb Fitting Kit (4x Fluoro lined silicone hoses and 8x stainless mikalor clamps) in red, blue or black

1 x NODIZ Pro Ignition ECU and Loom Kit

1 x danST Bike Fuel Pump Kit (new pump, not reconditioned)

1 x Throttle Cable Kit (all parts required to either adapt your existing cable arrangement or replace entirely)

1 x Pipercross PX600 competition air filter and baseplate cut out and ready to fit the carburettors

1 x main jet (1.5-1.6mm depending on advised engine capacity and spec)

This kit is ideal for anyone wanting to carry out the popular bike carb modification as an alternative to the old weber twin 40 style conversions. Bike carbs offer excellent performance, reliability and fuel economy when compared to the weber alternatives. These conversions are very popular in both modified and kit car circles and provide a low cost, simple power upgrade not to mention a fantastic soundtrack!

All of the above are 37mm diameter carbs and will support power levels up to 175bhp and are ideal for an 1800/2000cc engine in standard and mild levels of tune. This size of carburettor have been proven to offer better torque characteristics than larger 40mm carbs on such engines and are therefore ideal for a road and occasional track use. Exact model of carbs used is dependent on our stock levels, please use the contact form to enquire or request a a quote.

All danST supplied carburettors undergo a comprehensive inspection, strip, ultrasonic clean and rebuild process as required. Every set of carburettors are run on our dedicated test rig to ensure smooth idle and transition to higher RPM (see our youtube channel for running examples). We provide the carbs with base settings (and necessary jets) to allow you to get your engine up and running/driving. However these settings are only approximate and it is therefore essential that the carb jetting is set up by a competent engineer/mechanic using the necessary wide band AFR equipment (ideally on a rolling road) to avoid engine damage.

Carburettors will be one of the following models (stock dependent):

ZX6R

CBR600

CBR900

YZF600

ZZR600

R6

GSXR600 SRAD
