apparently you need 45x63 reducer (i think) off the turbo, a straight 100mm long 63mm metal pipe then 63mm silicone 90 off that
also another 63mm 90 metall bend
and instead of 2x 90 reducers off the core use 1x 90 and 1x45 (havent done this but apparently this fits better) and will be doing this myself
also what engine code have you got? do you have a map sensor?
