I have a set of Crower 63402A cams with Skunk2 cam gears that I am going to put in my car. I want to upgrade my valvesprings and retainers. I want to know if I put ITR intake valvesprings on the intake side and move my stock intake valvesprings to the exhaust side, and put either ITR or Crower retainers in, would that be sufficient? I plan on getting my ecu reprogrammed with a higher rev limit (somewhere between 8700 and 9200 rpm). Crower says that my stock valvesprings will be fine as long as I have the stock rev limit. If I can rev to 8700-8800 rpm using ITR valvesprings then I will do that. That will fit my budget a lot better that the Crower valvesprings and retainers. Any advice will be appreciated.

 

ITR retainers are the same as stock so no point in them.

 

Thanks. I wasn't sure if they were the same or not.

 

How do you like your crower cams????? I was thinking about going with CTR's in my 95 GSR but let me know

 

I haven't put them in yet. I plan to dyno it after I put them in. I'll be sure to post the results.
