Question for the all motor guys:

Are all retainers pretty much the same? I hear stories of Titanium ones wearing or breaking, others saying to stick with OEM ITR ones, etc...

i'll be installing a set of Toda B's into a JDM R-motor soon along with Toda valvesprings.

retainer-wise, i'm thinking of going with just skunk2 ones. Anyone opinions on these pieces of flat metal that cost a lot?

thanks!

 

There is a large thread on titanium retainers, you can search for that or chromoly to find the thread.

just drill a hole thru a stack of nickels and you're set for $0.80.

LOL! perhaps if i use some Japanese Yen, i'll have some hardcore JDM retainers too

(the search seems to come up with vague opinions of retainers..)

anyone?

 

check out this link and read the Physical properties. that should say it all.

thanks for the link dood.

i was a bit confused cuz i didn't know that titanium would wear out faster than steel. however, i don't think i was asking about titanium retainers...but it's not that i'm not grateful so thanks for the link.

Thanks for your input dood!

 

are you asking if the titanium retainers are the same from company to company?

 

well, i was asking if there was any problems with the Skunk2 ones, or perhaps recommendations from personal experience?

 

just get some chromoly retainers and call it a day.

 

any particular brands i should stay away from?

 

Just thought I'd share some info here. 1) All Ti retainers are not created equal. 2) They will wear out faster then steel ones and many people have different opinions on Ti's life expectancy. A handful of companies make Ti retainers and Im sure they are all good and have a performance benefit, but they are not all machined equal.

Heres some info on the Skunk2 ones:


From the 2007 catalog:
Many enthusiasts may wonder why Skunk2 spends so much time and effort into designing valvetrain components with reduced weight. Why is it so important for us to chase after grams? Without getting into the mathematics we thought we would try to provide enthusiasts with a simple explanation. By replacing Stock valvetrain components with Skunk2 Valves, Valvespings, and Retainers reciprocating mass can be reduced by an average of 12-14 grams. 1 gram is equivalent to the weight of a paper clip, which may not seem like much weight, but at 9000 rpm, 14g result in a force of approximately 32kg or 70lbs. Reducing the force that the spring needs to control greatly improves valvetrain stability, high rpm performance, and power output. Skunk2 Pro-Series titanium retainers are CNC-machined in-house from certified medical grade titanium that is milled in the USA

 

^^ this is what I was wondering...do they all look the same or does each company have their own distinct "style"

here's the RM from m24x.com. from the picture you provided us...right off the bat the top of these look different than the skunk2's

 

some really good info here.

" 1 gram is equivalent to the weight of a paper clip, which may not seem like much weight, but at 9000 rpm, 14g result in a force of approximately 32kg or 70lbs. Reducing the force that the spring needs to control greatly improves valvetrain stability, high rpm performance, and power output. "

thats pretty awesome when you look at it... i wonder what would happen if you took a stock d16z6, no aftermarket parts what so ever, and just shaved grams here and there, balanced, and rebuild how much power it would make.. what kinda changes in the power band, etc..

intresting...

 

dinko - are those retainers made of Ti as well?

i thought Skunk2 had cromoly/steel retainers too?

guys, great info so far. keep the posts coming!!

 

my RM Ti retainers look more like the skunks than the ones that you have pictured there. they have a small radius in the top. heres the pic.
