ok, alot of people email us on the choices of valvetrain for the D series everyday. So i hope this helps some until we finally get all the information on these choices on our site.

D16A6:
1. Isky Valve spring kit: (titanium ret, single valvespring) retainers weight half of what stock weighs.

D16z6/y8:
1. Isky: (single spring, titanium retainer)
2. Rev Valves: (single spring, titanium retainer)
3. Ferrea: (single spring, avail in titanium or alum retainer)
4. Zex: (single spring, titanium retainer)

hope this helps.. price comparison should be avail on our site soon.

 

Can't wait to see the prices and updates to the site. Keep up the good work and us informed!

 

thanks...
also FYI: there are other valvetrain companies out there that do stuff for imports but are manufacturing only for the B and H series, unfortunately nothing yet for D series from these other companies.

 

bump for Dseries power

 

finally we have valvetrain!

 

ok? i guess not that much interest? funny how we get alot of questions on it and no one notices here..

 

id be interested...im just waiting to see what the pricing will be.

i live in new york state...minimum wage jobs are even hard to find!

 

What are the differences between the Isky, Rev Valves, Ferrea, and Zex valvetrain? Is it mostly pricing or are there major differences in quality or application they are designed for?

 

Hayasa: they are all good brands..
as far as pricing, here is an estimated ranking from most expensive to more affordable:
Ferrea
Zex
Isky
Rev Valves.

 

Is there anybody that offers a dual spring set-up? Also are these just stock sizes or do they offer bigger valves? Thanks.

 

MOST of the cams out there for the D series dont really that high of a lift and are crazy enough to really need the Dual Springs. On the SOHC VTEC valvetrain, Ive known many racers using the stock valvetrain, since not even the wildest cam is that wild enough so the stock valvetrain can handle up to 8K.

On Valves, WE are almost done compiling the different valve choices for the D and B series. We are carrying Si Valves, Rev Valves, Ferrea, for the D series. All have the standard size as well as oversized valves.
