Actually kahit Hi-horse (140hp), blacktop(170hp) or silvertop(165hp) would be fine.
Magaan ang kotse mo kaya any of the three put into your engine bay would be an improvement. Budget lang talaga ang major factor mo. Word of warning though. lahat ng 4age ay high revving kaya don't expect much oomph down low in the rev range kailanagan galitin mo talaga ang makina kung gusto mo ma-feel ang arangkada. This is especially the case with the black and silver tops.

Pwede ka din mag hybrid na combo blacktop tapos silvertop na ECU. That will work nicely.

Syempre pagbili mo ng makina dapat may compression and leakdown test for all cylinders baka may tama and you will really have to replace all fluids, sparkplugs pati plug wires siguro just to make sure. Also dahil may milyahe na ang mga engine na ito pag nakarating na dito satin sa Pinas best to replace the timing belt as well.
