"Please, enlighten us all as to what makes the SR's head design so horrible and why the valvetrain is so "sorry". Where has this been proven "countless times"? And don't say "it has rockers" b/c there are plenty of other ohc engines with rockers...even KA's! "
^^Your right about both of the motors having rockers. BUT, the sr20 has FLOATING ROCKER ARMS compared to the shim and bucket design on the ka24de. Meanng that the KA24DE is way more resistant to valve float at high rpms then the SR20DET.
Also, when the SR was created it was made to save some costs, a rocker arm was implemented to press the two followers, so that 4 lobes could be used on each cam, rather than 8 lobes. This added arm can create difficultys when high-rpms are needed for more power
Another weakness, who in there right mind makes a twin cam with a single row timing chain like the SR?? at least the Ka24de has twin row. Not only does the SR have 4 lobes per cam. It has a V shaped rocker to push 2 valves per lobe - very unreliable at high revs.
DORI DORI, no offense but, when you bought your SR(assuming you have one) did you do any kind of research?
If my option and last resort would be to import a motor for my s13 it would definately never be an SR. Hands down it would've been a Ca18det. The CA18 has an Iron block and eats revs for breakfast that would demolish an SR valve train.
BTW, before you say anything about personal experience. ive had 3 friends of mine shatter there rocker arms on an sr20det. The proof is in the pudding.
**SIDE NOTE** The SR20det was also built in nissans greatest money depression.
if you need any further explanation/info just pm me. im sure people are dieing for this thread to dissapear.
