I am looking at Garrett part# 486827-6002 which is 23.7x12x3.8 and rated at 1000hp. The other core I am looking at is 703522-6005 24x12x4.5 rated at 950hp, what is confusing to me is how the dimensionally smaller core is rated at more hp and costs more. Is this a newer core design that is more efficient? I know the smaller core rated at the higher hp is a bit more costly so what else could it be? I would prefer the smaller core anyway because space behind my JDM Front is hard to come by.

Damn over half the message got deleted so resending that portion.

 

cuz maybe the 4.5 is not a bar and plate core and the 3.8 is a bar and plate core..

 

thats not it, i got my answer.

 

Well care to share what was it? thanks.

 

According to Turbo Elements the 4.5" is a much more popular core and they sell more of them, and that Garrett's ratings are incorrect and that they are in the process of updating them.
