Ive ran the isis T25/T28 replacement for about a year now on my SR and my KA deffinately a little laggy on the SR. Overall not a bad choice though for the price. I suggest getting a braided oil line kit with it. Make absolutely sure you use the tubo nut locking plates from the stock T25 ive seen isis manifold turbo flange studs back out on two different cars.
