hey guys,

i am having a problem with my engine. I changed out the alternator out due to the car not starting up and it is driveable now, but now the car won't rev past 5500 rpm now. Could it be rev limiting for some reason. Also while I was changing out the alternator I also changed the oem k20a2 intake manifold for the rbc manifold if that makes any difference. Have you guys dealt with this before?

you need to retune the motor after puting on the RBC IM. that is not just a bolt on part
