Incase the Precision sc6152e doesn't come through I have narrow it down into these two turbo. Which one will spoon faster between the two? It's going on a stock b20vtec. I know one is a t3 flange style and other is a t4 flange style. Looking for 300 whp on stock but will want 450+ whp when I have a built block ready.

 

Well, I guess I end up getting the precision sc6152e after all. Thanks for the reply though.
