俺以前的JD改过2。0~有点经验~
如果改2。0T的话你需要换曲轴（6千多）
连杆不用换（18T和2。0一样都是锻造）
活塞不好找~用2。0 2V的活塞压缩比太低（1200/套）而且有可能顶气门~
用2。0 5V的活塞压缩比比较高（一套原厂的接近1万）~不适合T用~
2。0TFSI的活塞估计也不合适~一个是活塞顶的造型怪异~再一个是没气门让坑有可能顶气门~
你现在是81的缸径~干完了是82。5的缸径~缸桶间的距离很小了~
另外搪缸最好下个缸套~但是目前82。5的薄缸套没啥比较好的~
还有就是下的套很难下到缸桶的最低下~EA113缸体高度短~2。0的话~活塞运行到下止点的时候~活塞裙部的一部分本身就已经出来缸桶了~会和你的缸套下面磨的~活塞裙部磨损会比较大~然后增大活塞间隙~然后就是在增压的恶劣环境下烧机油~降缸压~
不知道我说明白没有~
反正改2。0这个方案挺难的~
一个是不好找合适的活塞~另一个是搪缸下套有难度（除非直接买个PASSAT 2。0的缸体）~
总之~真要是改出一个可靠而且性能好的2。0T来~估计花的钱挺多的~不如塌实上K04~刷STAGE3~
我到是建议你找174KW的1。8T活塞~和连杆~压缩比8。7好象~嘿嘿~改到250匹以上没问题而且安全可靠！

技术....这就是技术....

SORRY~是176KW的1。8T~发动机代号BFV~上1代AUDI TT用的~
活塞配件号是：06A 107 065 BQ
连杆配件号是：027 198 401 B

强啊.......

男阿姨很专业，鉴定完毕。

技术含量就是高啊

看的俺一任一任的

EIP FORGED PISTONS
EIP Tuning has researched and developed a number of forged alloy piston designs. Over the years EIP has made the ultimate anti-detonation pistons for VW, which withstand high horsepower levels. Every piston is light weight forged alloy, hand de-edged, features tool steel taper wall wrist pins, spiral lock pin clips, high performance ring pack which provides quick break-in and a long life. The bore can be tight for reduction in noise and wear compared to other typical forged piston designs.
