T3/T04E 57 trim .48 or .63 A/R?

[Drackonn]

alright so I came across a deal and have a bunch of parts to boost my recently swapped b18b so I started looking for a turbo that would fit my needs.

this is the turbo I have decided Im gonna use but the question is what A/R ..

Stock B18b
Street use - my trips to the track are seldom because its like 2 hours from me
and Im going to be looking for somewhere around the 220hp range - if I get more fantastic

Im just wondering if the .48 will die out up top - even though it doesnt rev that high

I also have no clue what size injectors to run ... I appreciate the help - also I have been reading through the huge LS turbo thread on HT - but it is mostly - this is what my build looks like etc ... wanted to see if anyone had some solid answers- thanks again.

i would only run the .48 a/r turbine on a d-series. anything else, the .63 is a must

theres nothing wrong with a .48 on an ls. I had t3/t4 57 trim .48ar on my b18b ek. I made 230 @ 9 psi. I forot how much torque i made but it with that turbo it was very torquey. It was my first setup and i was very pleased with the results. It had plenty of room to make power. But on a gsr/typer/b16, thats a different story.

Trust me you'll be happy with both a/r sizes but if you happend to find a deal on a .48 dont pass it up.

I also used 550cc injectors on my setup just to let you know.

hmm...i would go with the .63 if you plan on rebuilding your motor...is you plan to leave it stock go .48....
