Hi , I was thinking about doing the following modifications to my engine , it's 1300cc engine , 1-rebore the engine to fit 1500cc high compression pistons 2-change the head gasket to a slim one 3-stroker kit 4-fast cam shaft 5-induction kit K&N 6-change the manifolds and the exhaust to a new racing HKS one 7-change the injectors to 1700cc. is it ok for my engine and should i apply a computer chip ? and should i change anything in the engine head , or the crankshaft or the drive shaft. and should i change the fuel tank or pump because the car will use more fuel ? what other modification does my mod recommend ?and also what are the throttle bodies should i apply them or something? and by the way i want to change the clutch plate to suit these mods and to suit driving in my country that has many peaks and hills and ups and downs so which plate suits the best . and i have another choice of changing the engine to 2000cc should i do that or not if it is ok with the mods i wrote please tell me if somthing is wrong or missing or shouldnt be done or should be replaced so i can go on with the modifications and if it doesnt bother if u suggest some trademarks for the parts please wright them .
