Custom Turbo

Hi, i am new to the forum! Hello everyone! I have a 2.7 V6 Tiburon. My Goal HP is 250-300HP. Ive been researching and researching and researching about Turbochargers and how to choose the correct Compressor and A/R Turbine Housing for the application you are running. So Far i have gathered information on how much lbs of air a minute the stock engine takes in which is 17Lbs/Min (170/10=17lbs.) 170=Stock HP and there is 1lb of air to 10HP. So know knowing that and knowing the pressure ratio (8psi+14.7/14.7=1.54PR) 8 PSI being the boost i want to run in my application, 14.7 Atmospheric Pressure. You also want to be 65% or more on the map, so on a compressor map for the Turbonetics T04E .60 Compressor Trim this Compressor will be good for my application correct? Now for the turbine housing i want a slow boost response and higher end power so a bigger A/R Housing will be suitable like .85 A/R Trim correct? I also am concerned about choosing the right turbine wheel. Should that be small for slower boost response? Here is my custom turbo on turbonetics website! Thanks! Any Info is appreciated!

What about upgrading engine internals?

Are you going to upgrade the fuel pump?

What about injectors?

Front mount inter-cooler?

What engine management are you going to use?

Custom manifold for the turbo?

Don't forget about the exhaust.

PLUS an $800 turbo! LOL!

I think you need to do some more research.
