SR's are gay

[Mooney1184]

just from my expierence with my 240. sr with front mount, lsd, 12 psi, profec b, blitz bov, afc II, 3" exhaust, it was a fun car, and i really enjoyed how much the motor loved to rev, but if i had to do it all over again i would buy a ca18det. iron block = ton of boost, one lobe per valve unlike sr's one lobe per 2 valves, all around better valve train, better bore/stroke ratio, revs higher than sr, intake manifold splits into 8 runners (2 per cylinder), 1 stays closed until 4ishk rpms and then opens for better low end torque, basically its a 4banger rb motor. the ONLY reason nissan stopped producing the ca is because of how much it cost to build, NOT because it was an old design. do your research. you want a sr killer??? ca18det head, ca20 block, and tomei stroker kit, you get a bulletproof 2.2 4 banger.

aside from that the ka isnt so bad itself, thye have come a long way in getting power out of the "truck" motor. i would so do a ka24det for drag simply because of the god like torque it produces. and in MOST cases of a stock sr vs. a well tuned ka24det w/ a simple t25, the ka will win the 1/4, but it lacks top end.

these guys do wonders with ka's www.ka-t.org

but thats just my 2 cents.

intake manifold splits into 8 runners (2 per cylinder), 1 stays closed until 4ishk rpms and then opens for better low end torque

+1 and good post, and I'm probably gonna get flamed for this, but:

I don't see why people like the butterfly valves in the J-spec CA. I've seen UK-spec CA's do some serious damage on and off the track, and they have a 4 runner-4 port design. None of that butterfly stuff. Shit, the highest hp CA18 outside of Japan is a UK-spec S13.

I dunno, I just think this would flow better than splitting it into 8 ports. Not to mention that damn near every CA I've seen w/ the head/intake mani off is gummed up behind the valves.





Oh, and I'm gonna reinforce my earlier post.

CA18ET > KA24. The KA in my 90 S13 blew up 2 weeks after I got it. And the CA18 in my S12 has gone through HELL with the last owner. Yet it still runs, and gets nearly 300 miles out of a 12 gallon tank. Runs pig rich, but fact is, it runs and it's not showing any signs of the rods saying hello to the fender wells after punching their way out of the block.
