从之前的人声鼎沸，到现在的人迹萧条，看来，帕拉丁的时代真的过去了。。。
可惜我没和农版，快爷等前辈英豪玩在一个年代，否则无疑会创造出许多值得纪念的疯狂之事来。
而如今，玩帕拉丁的不多了，像我这么玩的投入的，更少了，知音难觅，感觉我成了孤独的探索者。
不得不承认，国内的汽车文化和玩车的氛围，和国外还有有不少差距
而国内的论坛，和国外比也有不少的差距，技术贴和可参考的案例和资源还是偏少
下面我要说的，估计大部分车友不一定看得懂，先立一帖，后面慢慢补充吧。
1. 锻造强化发动机。换锻造活塞、连杆。锻造件的强度比原车铸造件强太多，最大容许每缸承受200匹马力。锻造强化的目的是为了提高增压值。
2. 高增压，目前使用的卡宴3.0的TVS增压器，匹配KA24，理论上支持1bar以上增压值。目前考虑到原车活塞连杆的强度，增压值被限制在0.5bar，还有很大潜力没有发挥。锻造强化后，将会把增压值调整到1bar左右。
3. 水喷射。参考宝马发动机的混合喷射技术，准备自己攥一套水喷射系统，往缸内喷水（对，你没看错，就是喷水）。目的是缸内直接降温，降低燃速，抑制爆震，辅助汽油雾化，提高燃烧效率。（感兴趣的可百度宝马的水喷射系统）
4. 以上几件事情做完以后，预计可以把KA24发动机的动力提到200kW，400NM附近，相当于4.0途乐水平。
5. 离合器、变速箱、传动轴、半轴，是否需要强化还未知，找不到设计参数，一步步来。哪位手里有靠谱的数据的，还望能提供点参考。
2018年2月28日，更新一些资料数据，说的是KA24发动机各个部件可承受的马力数值

Turbocharging the KA24DE can produce great numbers if the tuning is right. It's easy to attain over 200rwhp with a basic turbo kit like the kind sold on ebay. Advanced tuning and internal engine modification has produced KA24 240SX's with 500+ horsepower.
For a budget turbo build, you can get a t25 turbo and 5-7 psi without having to upgrade the injectors or MAF. You will need a fuel management unit (rising rate fuel pressure regulator). A new fuel pump is recommended. You also need to be careful with the ignition timing. MSD's Boost Timing Master can retard the timing appropriately.
The stock internals have been proven to be quite resilient. There are individuals who have made 350+ rwhp on totally stock internals. Here are a few quick limits on stock KA24DE internals. Keep in mind these are NOT EXACT NUMBERS. True limits can vary signifigantly from motor to motor. Before undergoing any turbocharging project, it is a VERY good idea to do a compression test. The closer to 180 psi you are the better. Anything below 150 and you generally want to start to think twice about a turbo project. So without further adue...
Pistons - Good for approx. 275-300 hp
Rods - approx. 400 hp
Crank - Indestructible
Valvetrain - No known issues
Head Gasket - approx. 320 hp WITH A GOOD TUNE (see below)
Head Studs - approx. 300-320 hp
...Ofcourse, all of this is dependent upon a good tune. As long as your compression, timing, and air/fuel ratios are all within spec, and the motor is not continually beaten upon, you can expect extended performance out of these parts. Many individuals are making 300+ hp on stock blocks with 200k+ miles on them! For a wealth of information on turbochared tuning for KA24DE and KA24E motors, visit the forums at KA-T.org.
美国玩车的朋友们，90年代就开始了各种办法玩尼桑的KA系列发动机的增压，2002年，两个资深玩家专门建设了一个网站，收集各种案例和数据，分享经验，现在已经有超过10000的会员和很多可参考案例。
