Hi, i just got my Greddy Type S bov, i know i will need to order a flange kit/adaptor to install it.

but can anyone tell me what size of flange should is use. I check greddy's site...it's has 16, 19, 29 mm for the outlet! It's for EVO, and yes, lancer shop have those , but it's too expensive, i tried ebay it's own 20 dollar shipped, but i need to be sure what size first. How much mm or inchs if you know.

thanks for anyone that will tell me. I did search first, but just can't find exactly measurmance.

much thanks
