I am going to install this cam in a D16Y8 head and rev it to 7,500rpm. Do i need springs and retainers, because some people tell me that I am safe to use stock springs & retainers and others tell me that I have to get atleast the springs, so I do not kno what to do. Do you recommend it be safe to stay with the stock springs & retainers or upgrade both or just the springs?

i think you should get the springs and retainers. dont just get one and not the other. just my 2 cents. you should try asking one of the veterans like ryan89crx,transzex, or autoworks. they would deff know the right answer

I ran a stage 2 on my old car without upgraded valvetrain and hit 7,500rpms with no problems. You can do it, but I wouldnt recommend it. Its better to be safe then sorry.

If I'd be building engine with Stage 2 cam and such of low RPM limit, I might want to experiment with stock (preferably fresh) springs with titanium retainers. Ti retainers weight half of stock ones, and they'd increase valve float threshold a bit. Loosing some valvetrain weight is always good thing too.

Thanks for your help. Do they have to be crower or can they be another brand name?
they dont have to be crower but i think you should the crower springs and retainers anyway,cause they were made and tested using a crower cam,you get what im saying.

I understand what you say, but I do not have that kind of $$$, thinking on getting the springs and retainers from crespocams.com, although in tunerchoice.com they sell the crower springs and retainers for like $250 for both.

im going to run a Y8/A6 mini-me with a crower stg 2. Im going to use crower springs and stock retainers. Don uses OE retainers on his D15B with a Bisi level X and P29s without an issue.

Crowers retainers are made from a high quality titanium alloy, supposedly not wearing out as quickly as some other brands.
I read this on a honda-tech thread perhaps a few years ago. I have the Crower valve train myself, and it works great so far.
