lol...I honestly never saw that there before...
ok heres my 2c...call hypergear, get a turbo and an adaptronic ecu off him if he still has any
or theres one here and get a 3076 if you dont want hypergear..

comes with built in MAP..if your tuner tells you its no good tell him to get his shit together cause its a perfectly capable unit (i know cause i have one) and you wont get better for that price unless you buy a used pfc or something which are getting alot cheaper these days
then get the best injectors and fuel pump (wired for full voltage) you can find..NPC clutches are great value too
for around 3k (which will easily blow out to 5k) you will be super fast...job done...
for the money it would cost to setup a 3037 (which really should be mounted to a decent manifold to be effective anyway) you could setup a t67 kando and be just as fast if not faster. there is far better ways to spend your coin than just getting a 3037
You cant just roll in here and say Which turbo is best, cause there is so many variables as to which turbo is best for your situation..whats the car used for drag, drift,burnouts, track how much money do you have to spend, is it daily driven yadda yadda yadda...but if you did a little research you would know this already..
as they say, ask a stupid question , get a stupid answer...
