which backhousing to use 48 0r 63 A/R
im really torn right now because i dont want alot of turbo lag but i want alot of power so i would like to know how bad is the lag difference between a 0.48 A/R backhousing when compared to a 0.63 A/R

oh and this turbo is for a b16 so i dont want a turbo that going to spool at like 6000 rpm parts i have so far are drag manifold(and yes i know about the wastegate placement),intercooler,turbosmart supersonic bov,dsm 450cc injectors and i cant remember the rest right now

ball bearing gt28rs with a 63 a/r would be perfect. but if you are sticking with the t3/t04e get the 63. it will probably come to life around 5500-6000 but the pull will be insane.

to each their own but I have a 2.0 LS/Vtec and I had the .63A/R housing and switched to the .48 since my car is mostly a daily driver and I like the quick spool, lots of low/midrange torque.
This car has 400whp so its not a light setup, nor is it that wild either.
.48A/R does not die up top (8700RPM redline) but it doesn't pull as hard as the .63 did. Its is not very noticable. On the dyno, I think there was like a total of 40WHP difference between the housings.
One thing to note though is that I also used 2.25 piping to help with quicker spool up but I think that I might be near the inefficiency range of my setup cause my horsepower and torque numbers are rather close, and that is usually an indicator either the turbo exhaust is near its limit of flow, or the system itself, cannot flow much more with more than minimal results.
I do not want more power so I'm happy with my results.

IMO I would say .48 for 300whp range anything more then that you want atleast .63 I dont mind lag so I would probably get a .63 for even 250whp car. You can run a .48 on a 400whp car, but you are limiting the setup at that point. .63 would be better for 400whp.
