- Sun Jan 20, 2013 4:18 am #324478 good to know the supertechs can handle a boosted motor, my setup will be tame in comparison.
-D16Y8 block with D16A6 pistons, ~10.5:1 comp ratio,
-D16Y7 head milled .025in with a port n polish, Bisi lvl 2 cam shaft, AEM cam gear.
The setup should have ~10.5:1 comp ratio, the stock springs might be ok, but i don't wanna chance it.
Next payday looks like I'm gonna be ordering some supertech springs and retainers.
any other suggestions are welcome, since this really the first motor i'm building myself. :thumb:

If you get to stiff of a spring it can lead to premature wear on the cam and/or rocker pads.

That's why I said the specs matter more than brand.

I will agree with ya, the specs do matter, but tell me truthfully, if you had a choice between two identical springs, both in specs and price, but one was made by Blox and the other by Supertech, which would you choose?
Brands do matter a little. :lol:
