Not sure how much I should be giving away in advance....
I've managed to run a 13.9 now, still with stock heads, cam and intake and street tyres.
Next up are two small jobs (hopefully!).
Replace the clutch fan with an electric one - just need a fan.
Convert to mass air from speed density. Need a couple of bits of pipe and an ECU.
There are other larger plans ahead, but at least some of those require money I haven't got at the moment. Plus there's some maintenance work required too.
