DSM Ferrera High Pressure Double Valve Springs/Titanium Retainers/ Valve spring seats
I'm selling one of the two sets of Ferrea double valve springs / titanium retainers / and valve spring seats (not valve seats) that I bought directly from Brent Rau, brand new. This is the same set up that Brent runs in his 6 second Mitsubishi Eclipse. Ferrea is the highest quality spring and retainer combination out there, bar none.
Ferrea made this higher pressure spring setup for the DSM 4g63 application; I expect that they are also the same dimensions used in the 4g63 found in our Evos, but have not researched that, so you'd have to do your own checking for your application.
The Ferrea part numbers are:
FER S10031 dual turbo spring
E11005 Ferrea titanium retainers
SL1002 Ferrea Spring seat locator
"Ferrea valve springs are developed from high strength alloys, including premium grade chrome silicone steel These springs are manufactured with state-of-the-art equipment. Our springs are heat-treated and stress-relieved, which dramatically increases the spring's life. Strict quality control procedures and cycle testing ensures consistency from batch to batch. Ferrea valve springs provide teh stability needed for high lift, high rpm racing engines, while minimizing the load loss for today's aggressive valvetrain combinations.
We expanded our Springs offering to include many new designs and applications. Our goal is to provide the best possible valve-train combinations for all racing environments from circle track, drag racing, motorcycle racing and offshore marine racing.
Specs:
- Spring O.D. - 23.1mm
- Spring I.D. - 17.35mm
- Seat Pressure - 90 lbs.
- Open Pressure - 210 lbs.
- Rate Inch - 305 lbs.
- Coil Bind - 21mm
- Max Net Lift - 15mm
- Spring Material - Chrome Silicone
Ferrea "High Pressure" Dual Valve Spring Kit: Mitsubishi Eclipse 90-99
Includes Dual Valve Spring (#S10031), Titanium Retainers (#E11005), and Spring Seat Locator (#SL1002)"
The combination costs $ 650 - $725 through the mail order discount shops. This is the lowest I found with a quick google search: http://www.extremepsi.com/store/cust...cat=1417&page=
I'm offering these for $500 shipped..
