Any experiences using Supertech SPR-H1002D valve springs with Toda Spec B cams in a B18C-R?

I'm trying to find out from experiences if they work well together and how long you have been using them?

Don't have much experience with the 2D kit. The DR is plenty of spring for any cam you can find on the market. If you havn't already purchased the valvesprings, you might as well get the DR since they are the same price.

I don't remember what the seat pressure is of the original SuperTech springs, but we use them exclusively on our builds and havn't had trouble with any SuperTech products.

I believe the 2D has a seat pressure of 70lbs at 33mm, which should be good for TODA B's. DR's are 90lbs if memory serves correct.

Speak in inches, you havent crossed the candian border yet!

I am Canadian but inches is fine! My concern is that the Toda spec b need a softer spring because of the ramp up and down...toda springs have 190lbs at 12.5mm and Supertech 190lbs at 12mm? The seat pressure is 70lbs on the Supertech and Toda? Toda Coil bind is at 12.9mm lift and supertech is something crazy like 19.5mm or so!

I just want reliability cause I will be racing this engine 1hours a week for 4 months!

We have a ITR motor that we run Toda B's with supertech ValveSprings. I Pretty sure I am running the DR setup but i cant be 100% since its been a while since i put them in and have since bought more for other setups. Either one will work fine but you might as well get the DR set up since its not too much more if anything !

I'm curious, does excessive spring pressure cause cam and valvtrain damage like Toda claims?

psegs80

does anyone know the install height of the Supertech 2D springs? I know Toda's are 1.325" and Larry From Endyn Recommends 1.400" install height with the spec b cams?

psegs80

Martin from Supertech told me that the installed height is 33.50mm/1.319" which is close to Toda's 1.325"...my concern is that Larry from Endyn recommends 1.400" with the Toda spec b and c's cams?

are this valve springs you talking about are they the dual spring or the single?

psegs80

They are dual...I have had them in for the last 2 weeks and I haven't had any problems so far...Mustang dyno I made 203whp at 8400 with my spec b's

ENDYN

Larry from Endyn doesn't recommend using Toda spec B or spec C cams regardless of valve spring choice....
Any cams that regularly break valvetrain components and timing belts should be avoided...
