I'll be investing quite a bit of money into a new valvetrain for my little built D but not sure who to go with. Is anyone running there springs/retainers in there D series? I was also looking at there Stage 3 cam, I'll be using Hondata so the ECU modification isn't a problem. It's still will be street driven so im sure if I sould just stick with stage 2. Anyways any help would be appreciated, thanks,
Matt

 

I'm running Crower single valve springs and retainers, but you don't really need them for a boost application unless you want to rap out to 9k rpm or something. I just got a killer deal on them so I went for it. Also the z6 or y8 cam works just fine if not great I wouldn't waste the money on an aftermarket cam for F1

 

I'm going to be running a pretty decent size turbo, it shouldnt have any problems making power to 8500 which is about as far as I want to go. What are you reving out at with just the springs and retainers? Thanks for the information,
Matt

 

7200(factory rev. limiter)

 

i plan on getting the stage 2 cam with the spring and retainer kit , ive herd good things about it

 

We run a full ferrea valvetrain on our y8. Dual springs, .5 oversize nitrate coated valves and ti retainers.

 

6800

 

Thanks for the input guys, anyone else?

 

sorry not trying to thread jack. what if your ganna push over 10psi would a cam be benifical? i mean im ganna be running a fully build bottom with sleeves.

thanks

 

A cam would be beneficial, but its hard to say how much so, at most boost levels. What you want is a turbo grind with maximum duration. Dont worry about getting any extra lift. You can find excellent regrind companies that will do the work for $150.
