actually i just converted to a mivec ck for my wira a.b .... me at sarawak... ck mean terbalik model..... nid mod mounting...... here i can do coz malaysia boleh 'u know i know la' :proud: for ur guys saying wat silvertop and blacktop mivec .. i not really know since we here now all left those out since ck model is much more newer as compared to those... parts are different also....... throttle size, oil rail and etc....... for md and non md mode, power are considred all same except md save more fuel..... but actually, got experience, using a mivec 1.8 non md(ori 1.6L cc hybrid gsr 1.8 block) , rm10 still can go for 70km+- .... if u cant mod mounting, i prefer u choose blacktop mivec rs which they say gud....... i know only terbalik model but for others i not much can help........ prepare 10k for the conversion since mivec nowadays damn expensive...... if u use for normal driving and more at jamming city,go for tiptronic or auto.. but remember to use gud quality AT oil,service well and install an AT oil cooler if can... if not when the gearbox gt problem might cost another few k..... if for racing purpose, of course manual since the gearbox ratio is really gud.......can drag.. lol
