it is imposible to get a cg13DE or a CR14DE, and even if i could the cost of it would be higher than getting a KA24 or a GA16 or the GA16 or the SR20 and having it already tuned up the engine, this datsun cherry is my project for life so i'd like a modern engine but also tuneable with a good performance, just a quest what modifications would be required to fit the GA16 with its gearbox withing the datsun? keep in mind that my datsun is manual not automatic, and any cut and shut of the transmition i wont do it because there is no one experienced enough in my country so i could risk to do it, i know this for sure because of the tuning clubs im enrolled with but ive never tuned a datsun before but its my project
