I bought the turbo and taka lines from HeavyThrottle, so I asked him and he said the taka lines should have it built in.ILikeMy240sx wrote:If you are using aftermarket SS lines, you would need a restrictor unless ofcourse it has one built in already.
If not, you can install one either on the block of the turbo. It doesn't matter where as long as it's somehwere in the oil feed line.
BTW, new GT2871Rs have a restrictor built in the turbo already.
