Looking to turbo

well im just looking to be able to hit low 13's thats all i want also about the injectors that i have right now are the 42.5 do you think this injectors will be good with 10lb boost ?? maybe 8lb ?? right now i have everything already install manifolds/injectors/LT1 MAF/oil lines/intercooler/Wbody custome PCM/ i just need tofind the right turbo i understand ebay turbos are not good but would one of this be able to last for at least 6 months while i try to get more money for a good turbo ??
 


boost doesnt tell you flow.

MAF freq or HP numbers or IDC will tell you how well your injectors are doing.

IDC is the easiest way considering there is no math involved.

But from a dyno you can calculate it.

Short answer? Probably.
 
oh ok well im going to dyno turn the car after i find the right turbo il check that any advice in what turbo should i get thats is not soo expensive ?? or do you know if there someone that is selling a used turbo here in the forum
?
 
bullseye S256 is decent, as is a precision P61.

But a T67 seems to be the more common choice for bigger builds.

T72 is more "balls to the wall"

Note: no turbo costs $300....

$800+ unless you're buying used.... and that can be a nightmare.
 
thanks thats a big help i will try to get one of those ...whitch one is less expensive ? do you if someone is selling one of this ?? will replicas work ? for 6 months ? is godspeed an ok brand ?
 


i really need to get a turbo my car has been in the garage for almost a month already and i need the car but i dont have $800 right now only $400 thats why i was trying to get an ebay turbo for right now while i was trying to get a good one but i guess its not worth it i will need to wait another month to get the money ..
 


i guess i will need to do that thanks and this is my car by the way link///http://www.cardomain.com/ride/3893101/2005-pontiac-grand-prix-sedan-4d
 
10 lbs of boost? the eaton M90 supercharger that comes on the new GT's make that. or i had mine register that on the boost gauge.
