i mean if your just flat broke and on a straight budget (which it would help to list your budget). d will get u there. lets face facts a stock sleeved 500 hp d isnt going to last long same for a b an u will go threw motors. so u really cant use that as your basis. me id start with a b just a better start platform. for a few hundred bux motor into the swap u can have higher hp motor. because i your not boosted right off the bat.

this is a very noob question is a high goal for your knowledge level. i see people all the time want to just head strong into something like this and hell it never happens (swap and boost same time for a first timer). start off with a nice clean swap learn a few things then step up to the next level after you get some time skills under your belt.

sry for the lack on punctuation other than periods. its the internet i dont use them unless its important.
