A guy from Greta NSW that I got to know through selling him some Sigma Turbo parts has EFI'd his GK.
He was on the old site as Myturbo. He had a home made turbo setup with an SU and custom inlet which involved a home made crossover into the stock GK inlet manifold. Went OK. Similar to my factory job.
Well now he has fitted Magna EFI with all stock Magna injectors, computer , throttle body etc. Ditched the turbo
Fitted it all to a M1 GN head. Nice extractors and system .What a beautiful thing to drive ;) Far better bottom end power than the old turbo, similar midrange, but just doent go on with the power delivery at the top end like a turbo.
Just great to drive around town. And all up all it cost was a weekend under the bonnet and $200
EFI GK Sigma..............Beautiful
