So I went on a family holiday to Florida for a few weeks and couldn't resist buying some parts for the build, Really good savings to be had, I bought a set of Siemens Deka IV 630cc Injectors for £90 rather than the £200+ they are here, Also managed to get an AEM Wideband Lambda with sensor and gauge for £100 again half the price of the UK. Couldn't believe how cheap it was, just had to worry about US customs thinking that I had bullets in my bag lol

The Siemens 630cc injectors will easily flow enough with some headroom to the desired 300bhp so I thought they were the perfect choice:



The wideband will be more of an extra bit of insurance for me so I keep an eye on the AFR and don't end up melting all my hard work



Does anyone know the best place to mount this lambda sensor as I imagine the manifold and downpipe on a turbo car to be a lot hotter than a standard one, Would I be ok putting it where the cat would be on a modern car? and do I need to angle it or can it go in straight?
