Hi Guys & Gals, Currently doing a 7KE EFI setup on my 4K test rig engine, which if it works well, will go onto a fresh 5K engine, yet to be completed. Nearly got everything finished, and the Haltech E6K I'm using, is all wired up. Got a brand new Haltech O2 sensor & mounting boss today, and am not sure where the best place to fit it ? I'm running a 4 into 1 extractor, and thought possibly the easiest & best place would be where I've marked with a "white" circle. However, it occurred to me this is a fairly turbulent point, as all four exhaust pipes meet here. Maybe a better place would be a little way further down the exhaust pipe ? Most manufacturers of modern engines put the O2 sensor up on the exhaust manifold somewhere, relatively close to the engine. Is this for convenience, or would a better spot be further down the pipe. Appreciate if anyone who has done this before, could give me their thoughts. Here's a couple of pics of the 7KE EFI intake on the 4K. No distributor Pajero acelerator cable (thank you Nesta) No mechanical fuel pump Cheers Banjo
