ka24det does not exist, you have to make it.Also refered as KA-T.
ps:t3/4 is a good size up to 450ish hp.the t28 will not get you very far, unless you have modest plans for your car.Even the XSengineering kit uses a t04b, ill have to check it out.
edit:XS uses a t3/4, sorry
by the way, like my man Bubb Rubb said, its all about the flow!A sr at 8000rpm that flows 450cfm(i dunno, random numbers) is the same thing as a ka at 6500rpm flowing 450cfm.
