OK, I started to buy a few things for the turbo build today. Got the boost gauge, water temp gauge, intercooler, BOV, and charge pipes. Going to go custom and use the F/IC at has been recommended. Everything else about the kit will be easy to find/buy except the turbo..... here is where I'm having problems picking the right one for my application. I'm looking at UP TO 200HP, but not OVER 200HP. 99% of the time this will be my daily driver. These are a few ratios I'm looking at but can't seem to make a decision....so I list what I'm looking at:

T25 or T3...
.42/.48
.42/.63
.48/.60
.48/.63


EDIT: redline is around 6500 RPM's.

 

You need wheel sizes as comparisons . not just A/R housings.

 

I know but I'm trying to keep it basic and not introduce too many variables. That being said, please feel free to recommend a specific turbo.

 

what about a sr20det red top turbo. I have a chance to get one for a good price and in good condition....


EDIT:
# Turbo Specs:
# Compressor: T-25, 60 trim 56mm
# Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.

 

i went with a t3 .42/.48..I let you all know how it goes....
