dont go for both go for a 3sgte i saw one fitted with in Peshawar it literally takes off flies and the maintenance is the same for the 3 of these engines, yes and if you want something more practical, which can be your daily driver, economical, easily available, easily maintainable , bolt on fit, and still be scary fast get a 1zz-fed and just buy yourself the official toyota trd super charger for it which fits with out modifictions . doing all this will save time, money,reduce issues faced as it is a common engine, it will give you less issues and parts are common due to se saloon and altis -2013 . that should be abreeze and then you can start worrying about the looks and not engines, power will be just enough for you to not have to upgrade too much likes brakes and the suspension and chasis will not need a brace i guess and due to the light weight of your car it should be very very very fast , and it wont sound like a thrasher is going off in neighbourhood when you start your car and drive buy ......atleast not due to the engine if you use the stock exhaust setup aswell, because the altis goes from 0-100 in about 9 seconds this should have roughly 160ish horseys ofcourse that is dependent on engine condition and other factors as well but in more general terms it should go from 0-100 in less then 8 seconds as per speculation could be faster then 6 aswell but faster then 8 seconds you will be able to beat most stock and normal cars in most imaginable circumstances barring the turbo civic which alot of people wont have and it should be fun for that reason so 1zz-fed + trd supercherger= minimum skill and time and money = maximum thrill in a ke-70:S
