Okay help me out here guys... Ive been aquiring alot of new parts recently to rebuild my head on my GSR. So far Ive got: Gaskets for EVERYTHING, New ITR LMA's, New Valve seals, New Timing Belt, and all fluids. On my car I already have installed the ITR cams/Valvesprings and Adj. Cam Gears. I need to buy some new valves(mine are slightly... shall we say "tweaked") and I dont have any first hand knowledge on them... I will post what I know here from research Ive done the last few months.

1. Flat faced valves could be better for N/A because of a .3 cr bump.
2. Oem/Omnipower/??? wont snap off in the engine like most aftermarket hardened ones because they are a diff alloy.
3. Inconel is desired, like the OEM valves have, because of Better High-Heat protection and smoothness... or a nitride coating of some sort.
4. All valves use OEM valve keepers.
5. Undercut stems improve flow by a small amount (cuz its thinner).

So which brands are KNOWN to bee good. I mean they all LOOK good... REV/Supertech/Crower/Toda/OEM ITR/Portflow/Manley/Skunk2/Omnipower...etc

Which ones really are the **** and why? I am looking for some REAL facts before I go drop this cash on them right now. Ive been workin my *** off on getting my car runnin like a champ... As soon as I pick up a set of these my head is off to Alaniz Technologies for a Stage1 and an Assembly/Rebuild.

Also... I was thinking of using my stock retainers. Im not going to be revving past ~8800 ever and I dont want to worry about Ti ones breaking/wearing down. How many of you with these have had them for more than a year or two without any issues?

Thanks

 

very interested... i want to know/learn too.

 

i have heard good things about supertech's valvetrain. p.m. earl he can help you with your needs

This is correct, Ive talked to Earl and he has decent pricing on these also... Ive heard good things about alot of brands from alot of people... but when I ask them why, they are like ...(mute)...

What valves are you all running up in those heads... c'mon now...

BUMP!

 

im just running .5mm oversized type r valves in my head

 

i have si valves over sized/undercut valves. i havnt dyno'd yet, but the engine pulls for a b18b.

 

Nice to hear that OEM is holding up well under boost and in built motors.

Bump.

 

Bump, Bump... Bump Bump it up! Thx

 

I used modified GSRs in my build with skunk2 valve springs and stock retainers (9k and no problems). I personally think ferreas are the best out there, but then again, they cost more too.

 

I keep reading good things about this Earl guy. Does he have a website?

Thanks

What do you mean by modified exactly, please elaborate.

I am hearing more and more about stock valves. Im sure for N/A they are cool, and alot of people boost on them... but for long term boost or "maybe" even a lil squeeeeze wouldnt something aftermarket be better?

Thanks for the input... keep it coming Honda-Tech, thou art my mentor...

 

I believe RLZ uses OEM ITR valves in a lot of the heads they do. If they're using them then that's saying a lot.
