The idea is i've got the standard filter housing (which will be made more holey) that has a k&n replacement element, i will be fitting a small bore LCB with a twin box RC40, the hif fitted to a 'superflo' inlet manifold. Other than that, the engine is standard and will stay like that
So basically, a stage 1 kit of sorts.
Any guru's like to help me choose a suitible needle and spring (which given my choices i assume i a red one?) i've been looking at http://www.mintylamb.co.uk/suneedle/ but i'm not entirely sure what i'm looking for

Cheers!
