guess no one really cares about the ka-e anymore? i mean, not really receiving any feedback so don't really know if i should keep going with the specs.

[w0nderbr3ad]

Its not that no body cares about the specs, its that a majority of people wouldn't know what to do with the info and without proper tools its hard to measure these specs. If you had your hands on the DE specs I'd be grateful.

yeahh, didn't really think about that. and actually i do. i'll probably throw them on after this weekend. it's gonna be a busy one. driving back home, doing the clutch on my truck, pulling the old de motor out of the 240, bring up the e and blah blah blah. and i don't know how many motors people rebuild on here but you're right. usually just have the machine shop do all them. but like i said, i've got some de specs. not as much as the e, don't know why. still wish i had a scanner.

['89240sx]

i kno this is an old thread but i appreciate it cuz i just bought my first 240sx and it has the ka-e

[Scuba002]

[chr1su12]

[S133P3R]

THANKS!

[soon2Bcool]
