Springs and valves

[FyreDaug]

What do we have for aftermarket support for these? If theres nothing or its not worth it, what about other motor parts?

I have access to a shop where I went to highschool where I can measure the stiffness of the springs, so if I get something from another car I can be sure they are stiffer. I plan to have my motor up to 8000 safely.

Anyone know what springs will fit? I guess aslong as they are the same width/height they should fit right?

As for the valves, I dont think I need anything aftermarket, or anything from another car since these valves fit in the head fine. And Im pretty sure lightweight titanium or something is fairly expensive and not needed for only 8000.

make sure they can compress the same distance as stock to so they don't bind up.

I looked into these guys a few years back.

yaeh si valves shows part numbers for high performance "swirl valves" for our motors. they could probably set u up with the whole valvetrain though i would imagine...

they have stock numbers but if you want the swirls they have to be custom made. 30 bucks a vlave. I called them on it last week or the week before.

makes sense. i wonder if they know the limits of oversized valves on a20 heads!?!

that's not a bad price, considering new valves form honda cost $20 each.
