not sure if there are 4G63 N/A for pizzapie lancers but 4G63T meron, gaya ng sabi ni A121 evo 4 up salpak yan.
meron na yata gumawa sa isa sa mga forumer ng http://www.mymitsuph.com na 1st Gen 4G63T sa pizza lancer pero with a lot of modification sa engine bay kasi iba ang orientation ng 1st Gen 4G63T.
as for the mivec, mahirap ang spare parts nyan, meron din sa http://www.mymitsuph.com na naka pizza mivec pero binebenta na, don't know why.
and tama ulit si A121, both engines (2nd Gen 4G63T or 2nd Gen Mivec) will cost you 80K+ just for the engine, tranny and ECU, wala pa installation cost dyan pati iba pang additional na cost (e.g. suspension upgrade, brake upgrade, etc, etc.)
