K24 retainer update

[wed3k]

So if the spring fits, the k24 retainer looks way lighter than the f22. i have measurements and weight but ill need to measure a f22 retainer and compare.

Whoa whats all this? Are we looking into K series valvetrain parts that might fit in our heads?

Any benefit to using the K24 spring and retainer? Pricing/stronger?

Hmmm . . . Might look further into this.

Last I looked the spring free length between the B/H/K were significantly shorter than the OE F22. Are you just talking about the retainers or the whole assembly?

I can weigh stock steel JDM K20A single spring retainers if you're interested I can get you the coil free length too.

just the retainer...it's a lot lighter. i was tempted on swapping a customer's retainers out with my f22 ones

good alternative for those who dont want to run titanium. titanium is good for performance but ive seen them fail from people who dont constantly check the condition.

Fred: there's no point on a k20 since those are harder to find. K24 heads are plentiful and i know for a fact that they are lighter and thinner.

Pretty neat stuff you've figured out. So basically both intake and exhaust retainers from any k24 head will fit into out F22A heads? Interesting...

i just need to check the spring diameter and im going to load that into my car before i forget tonight,

[wed3k]

oh, so it only saves 2 grams
9.7 vs 11.3grams

it'll work with the f22 spring.

[BIGsnorlax]

Well 2 grams is 2 grams ha
is that per retainer i assume? Ive never actually weighed mine ha

[wed3k]

yea
