I am thinking of doing a full kms valvetrain upgrade so that i can raise my redline. If i got the kit, what do you think that i could take my jdm h22 up too? The kit says that its safe to take it up to 11,000 rpms. Is there anything else that i should do to make the motor safe to rev up to at least 9500 or 10000? Thanks

 

i have a fully built jdm h22a top to bottem built i can bring it up to 9 grand with n o problem

 

why do you want to rev that high?

 

so he can go 120 in second gear
