i have been given an option to change engine to 3sgte ( 6 speed) forward. engine not in country at the moment to see but i hear its a clean engine.
currently using 4age20v.. i am satisfied , no troubles .
recaliberated speedometer adds up lot of top speed,, quite unusable for Pk use.
only difference is after swap car should get additional power in 3rd and 4rth gear and turbo tag at back:)
moving ,, from naturally aspirated to corolla turbo zone.
plus mileage will go down,, may become unpractical for long drives where fuel stations arent closely located as car's fuel tank is pretty small.,,, as is i can finish full tank in minutes if i want.
so far i think swap is waste for money.,, all ready car is above average family cars category in Pk where power/weight ratio matters.
