Hi, yeah, you need the 9 inlet manifold, unless you fit your own map sensor to the original manifold. Didn't wanna drill the original manifold, so just put the 9 one on mine.
I couldn't find an engine loom in the U.K. for sensible money, so made my own, should be a lot easier for you if you have an original 9 engine loom, should just plug straight in....forgot to say in the thread, you'll also need the top timing belt cover from the 9, the 8 one won't fit over the Mivec pulley.
Sorry for the delay in replying, haven't been on for a few days, cheers, Andy.
