I have the chance to wait a week and get the S15 turbo or I could get the Isis turbo now I just want my car finished asap but i'm not sure which to go with is there a really huge difference between the two?

I've heard great reviews on the isis but if the Spec r will spool up thaaat'd worth it to me. Also will they produce the same power or is one gonna make a big difference?

Anyone care to elaborate? Also it's going on a ka24de.

Also with the S15 turbo if I'm using s13 Sr20det inlet and outlet pipes will I need clocking adapters?
