Not that I mind...but it would help you out a bunch if you would READ other posts before just posting something that was answered like a week ago!!!

KA24DE's are good for up to 400-450 on stock internals

SR20DET's are good for up to 400HP or so on stock internals

But they are inherently different...KA's have torque and lower redlines and higher compression ratio's while SR's are more race engines w/higher redlines a bit less torque (but still lots), and lower compression. KA's are iron block's while SR's are aluminum.

My choice...KA w/turbo kit...SR's are cool and all...but you dont have to pay lots of money for JDM parts and have them shipped over here...

Go w/F-Max kit stage II or Nsport stage II. BOOST AWAY!
