Well heres my 2 Cents if ur breaking in a new motor then yes take it easy but we are talking about a modified motor as in built internals like pistons and piston rings and for the rings to seal properly they do need to heat up but that does not mean beat on ur car strech ur gears and always be shifting into different gears and at different rpms never be cruzing especially for the first 100 km i did my 1st oil change after 100km and all the small shaving from the pistons and s*** came out witch is a good thing after that i did the same thing and changed oil at 1000km and there was very lil metal shaving after that i did an oil change at 3000km and then 5000km but one thing do not use synthetic oil untill u have completly broke it in any questions you can pm me ive been there asked all the questions
