need to decide which turbo to get . its for an h23a1 and my goal is to get 250 whp . i am guessing the redline on the motor is 6500 . i want something as a daily and street driven car and maybe take it to the track 2-3 times a year . i want something to spool around 2.5 - 3k and make power all the way up to 6k .

i decided between these two turbos and cant figure out which one would be the best for me . after researching i found that the .48 spools quickly butt doesnt make power on the top end . butt the .63 doesnt make good low end butt makes up for it on the top end . i was originally going to go with the .48 butt i didnt know how much of a power difference i was loosing in the top end considering redline is like 6500 . please help me decide .

go with the .48!! For 250 hp, u dont need that much flow that would require a .63. And for it being a street car, .48 will be more responsive.

For a longer rpm range on honda dohc vtec motors. I would go with the .63ar, since you will need stronger spools on top end. (We dont want to be losing power on top end now do we? ) t3to4e usually spools up pretty quick anyways. 2800rpm to 3200rpm range. Pretty much all it is , is the 1st gear you be waiting. then from 1st to 2nd to 3rd gear...its pretty much reved up high enough to be in full spooling. .63ar all the way!!
