wan520i, kau betul n aku pun betul.
pasal e39, mcm aku tulis, certain 525i ada m54b25 n certain 525i ada yg m52b25. tgk pd tahun kereta tu dibuat. anyway, it's not that difficult to differentiate m52 n m54. tgk accelerator pedal sudah tau.
if m52, tgk enjin dah tau whether TU or non-TU. kalau ada 1 lump, single vanos lah tu. kalau ada 2 lump, double vanos.
523i: semua m52 engine. takde m54 engine.
bmw badging kdg2 mengelirukan utk sesetengah org. kalau nak tau engine apa engkorang pakai, bukak bonnet. lagi clear.
for european(ECE) market:
utk e34, 525i ada 3 versions. yg pakai m20 engine, 170hp. yg pakai m50 enjin, 192hp. 525ix (4-wheel)pun ada jugak, pakai m50 enjin, 192hp
utk e39, yg mcm aku tulis, m52b25 n m52b25tu ada 170hp
m54b25 ada 192hp.
so, jgn terperanjat kenapa certain bmw lama lagi byk hp, if banding kan cc yg sama. kenapa mcm itu? itu kau kena tanya bmw ag. aku bukan automotive engineer.
lagi best, utk e34, dia punya 530i ada pakai m30 n m60 punya enjin. yg m30 tu 188hp, yg m60 tu 218hp. haaaa, mcm mana tu, 2.5 m50 enjin lagi power drp 3.0......
so, wan520i, harap kau dah clear pasal kuasa kuda-kuasa kuda ni. ni semua tak penting. yg penting ialah, jgn pakai e46.....hahaha........kereta bodoh....
