only problem with calling percision or one of the bigg companies is...
they are going to try and market you a billit dbb q/p housing turbo and your talking 3,500-5g nad if your talking a comp class turbo you can go up from their.
than they may try and get you to port/clip,fence the unit which adds on.
think about it this way..
you can drop 3-6g on a off the shelf unit
you can drop 4-7g on a modded custom unit
you can spend 800-3g on a used unit
their are options like a hx45(off a desile truck) that are dirt cheep buy a back housing and walla you have a good contender that will flow 30-60 psi ( you could even go with a tial stainless machined housing that wont ever crack and will drop your weight plus is the shit and flows better than the cast unit
their is options likes300/s400(borg warner) that are t4 or t6 fotprint that will flow 1000whp+ and dont require you to brake the bank and are easily rebuilt where the new units reqire the whole center section to be replaced unless its the new percision center housings that are rebuildable but i can say i spend 3,500 on a 72mm with a q housing and it was dbb billit(off the shelf turbo)
again you can buy whatever... but you can get a turbo that will hit early and taper off on the top or you can get a mid rang or one that has some lag but makes it on the top end. with a bb motor id be shooting for a mid-top end you are drag racing odds are your on a trans brake or 2 step(if not both) and dont have to worry about spooling it.
are you running exotic fuel or pump gas... are your spring in the head up to the task of holding back 30+psi ive seen test where valves were pushed open because not enough seat pressure, how much air are your heads going to flow.. how hard can you spin the motor(you dont need a turbo that wakes up at 4,000 and makes power till 9000 if you cant spin it that hard..
their is such thing a turbo map and its not super hard to read you just need to know the general info than you can choose your options from their.
sorry about my rant.
