This kit has been specifically designed to work with the factory fitted existing single point engine management system. No modifications are necessary

Please beware that if prolonged speeds of 100mph are envisaged the engine may run lean and could eventually lead to engine failure. Power output figures of around 80bhp are normally expected after fitment but is dependant on the original engine build (rolling road tests have consistently shown 20-25% increases).

Figures confirmed by Swiftune Racing. Extra BHP can be obtained with professional air box modification. Further power increases would necessitate modifications to inlet manifold and use of a tubular steel LCB exhaust manifold. These performance figures apply equally to both kits and the only difference is the material of the valves and the different type of 1.5 rockers used. The budget kit uses forged rockers and includes 4 extra washers to shim correct alignment over the valve stems. Fit 2 of AEG168 washers between post and rocker on both of the two center exhaust rockers and refit both end spring washers between post and rocker for correctalignment. The performance kit uses roller rockers which should also be checked when fitting to ensure alignment over valve stems is correct. 4 multi point nuts are included to use on the rocker posts to eradicate fouling of the rocker sides
