6.5k rpm is n/a carby limit not the gearbox...correct me...
yes the engine is the limit....ok... short ratio need to counter with engine rpm to get the speed...
660 boxes are too short... when using with EJ block with limitation of 6.5k rpm how could u get speed with 660 boxes?... hehehe
longer 1.0 box ratio can be solve since u has a badass torquey engine from LOW rpm......with 6.5k rpm speed in 4th gear u already above 160kmh
but with 660 box, 6k rpm in 5th gear just around 140-145kmh if i recall correctly lah.. now my kancil already auto.... heheheEJ, OR ED stock factory RPM redline are 6500rpm..but actually ecu were set 7k rpm how fast u can destroy an engine which are modded and running beyond the limit...? even in stock form the engine can be destroyed in a minute running way above the limit of the engine design itself... hehehe.. plus originally the engine was made for normal aspiration... taking boost into the account ... would set another risk into engine??....... if u sayang the engine u just done.. just dont over rev.. as u stil using stock EF-JL ecu.. would enable u to rev up to 9k rpm b4 revcut.... u need to control ...running over rev with stock internal made for n/a which just have 7k rpm limit..... u might burnt the new main bearing and conrod bearing or any rotating part maybe not able to take the stress of another 2k rpm with boost
.. plus u just put the oil jet.. are u sure stock oil pump pumping enough oil to all rotating part which need lubricant???the reason there is performance internal part.. forged piston, crank balancing, hi performance main conrod thrust bearing..<--this one is in general..
