Under shim bucket kit qustion

[Jimmi The Kid]

I can see the TRD N2 uses 304' with 10,0mm lift on the intake and 272' 288' 300' and 304' with 10mm lift on the exhaust.

I think I will go for a set of 304' 10mm lift on both intake and exhaust. I know one who use the same setup on his smallport and it produce about 200hp @ crank at only 9000rpm.
I don't wanna build a really high revving engine, as the revs will kill it in a few time. Otherwise, I could buy the old Atlantic engine I was offered, but I dont wanna rebuild it every 2500km and it for sure not good for the street. The price is also a bit too much :wink:

What springs beside HKS and TODA ? And of course TRD which I can't even goo look how much they cost .

Are HKS good for 10mm lift ?

What about stories that some Supra/Celica valves can be used ?

Does anyone know what diameter/lenght/rate TODA/TRD/HKS valve springs are and help search for alternative solution ?

Thanks
