240turbo

Hi im newb to this form i have done alot of research tho . I have a 1970 240z with a 1983 l28et motor . but less fuel injection. I am going to be running weber dgv 36 32 down drafts. The thing is im going to be blowing thru them. I have done all the apropriate carb mods and studded the block . I will be running the stock garret turbo for now , with 2.5'' piping and 27x8x2.5 fmic. and then pressure box ontop if carbs. 1;1 fpr and wide band . Has anyone done this on this site that can possibly give me a few pointers? thanks
