negative... the ZEX 53900 is a stage 2 cam. your OEM valvesprings will work for a few thousand miles, but they will need to be replaced quickly. look here, then decide for yourself (ZEX 53900 is more agressive than crower stage 2)

go with the ZEX stage 1. $260 shipped from nipponpower.com. should be a solid 10-12whp bolt on.

 

how much is it to upgrade the valvesprings...........and this is such a newb Q but what exactly are they and how hard is it to get at them.

You're right, I meant the stage 1 cam, but I put the part number for the stage 2


As for the price of valvesprings, I just saw the Skunk2's for $230, so I imagine around that price range.

 

i personally dont believe that the zex stage 1 will offer that big of a hp gain, maybe 5 or so, but i dont think 10+. in all honesty if u are gonna put a cam in your car you should get all u can out of the cam, which usually means at least valvesprings and increase rev limit. valvesprings can be found for like about 150 for a set of crower or zex to like 250 for the skunk2&lt;- only my dumb *** would buy them . as for changing the valvesprings, its not really hard, it can get tedious and be a pain in the ***, and is much much easier if the head if off the block cause u dont have to worry about droppin a valve in the cylinder.

huh? go look at the specs again. intake lift on the ZEX stage 1 is as much as the crower stage 3. with some other bolt ons and more agressive fuel maps, i think 10whp is a reasonable estimate.

yeah, but you need TI retainers too. both are $277

OOOOO I was looking for that website...thanks man

I'm personally going to go with the Exospeed Street SV...not too aggressive and only $200 bucks...can't beat it PM ExospeedAMCRX on this board

 

From our opinion when we designed our cam, the SOHC VTEC doesnt really like SUper high lift that much. Its not like the DOHC VTEC which have a pretty good lift, the SOHC worked well with a decent lift and a matching Duration. A combination like that works real well on the street, reliable and also great for the track.

 

That is nice to get info from a sponsor because they probably would know more than I would def. What would you choose for a cam, springs, and retainers for a d16y8 ?

the intake lift is close, but the exhaust lift on the crower is much bigger than zex. also the intake duration on the crower is much larger than zex. i think it was import tuner that dynod the 59300 a while ago- got like 7 hp gain, but i think the engine was otherwise stock. while 10 whp is probably attainable, i think that somewhere around 5-8 is more reasonable.

i'd like to know the same...

what's wrong with skunk2 valves?

 

why would you spend the same amount of money for the stage 1 zex cam when you could just get the zex stage 2 59300 cam? Getting 10whp out of that cam is definantely pushing it. If you want that much power get the stage 2. Even then your probably gonna have to tune it well to get that much power. You will be fine with this cam and no valve springs as long as you don't rev past the stock redline. If you want to make the most potential power from this cam then you will need to raise your rev limiter and get the valve springs. I believe you can make power up to 7800rpms with this cam.

ok, i need to be more specific. i expect around 8whp from the cam, and a few more from retarding the cam timing 2deg. i also have another bolt on that i think will help achieve 10whp from the cam

Your point is?
I have had a reground cam in for 10k miles. Not a hint of a problem.

again, i'm going to have to disagree. you may be Ok for a while, but the springs will wear out very quickly. look at the specs.... why in the world would crower say that springs and retainers are required with their stage 2 cam if it didn't need it? again, the 53900 is nearly the same duration and more agressive lift than crowers' stage 2

again, lets go back to the original question in this thread. i believe that valvesprings and retainers are required for the stage 2, and that's why i recommended the 51900

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by ladysman &raquo;</TD></TR><TR><TD CLASS="quote">Your point is?</TD></TR></TABLE>

my point is that i'd prefer the longevity from a cold core. that and i'm willing to pay the extra $$ to buy a cam from a company (comp cams) that has been making cams for decades

I had our A6 cam in my motor for almost 100K miles. drove it everywhere for 3.5 years. Street raced every weekend and hit up every event i can go to. hit 13.6 first time out... and was still running strong at mid 13s 3 years later.
thats my testimony with using a reground camshft.

 

please keep this topic alive...i'm learning a hell lot about this head build up. Interesting debates guys!

again, great input directly from the sponsors

it must be one of those "import myths". i was always under the impression (based on input from others) that regrinds have potential to be very weak if ground too much.

 

they probably said that beacuse valvesprings are required to max the cam out to its full potential. Maybe they also want to get you to buy their valve springs and retainers?

Not a myth anymore.
