The best bang for the buck is not buying them if you don't need them. If you are running a turbo, the turbo forum will likely tell you if you need them.

There was a thread a while back (in the NA forum) with the different manufacturers of springs. One was cheapest ($385.00) but wasn't suitable fort higher redline (according to another member, I didn't need to verify it, so you will probably want to if that is an issue).

If you are not raising the redline, I would just by the TWE springs with out retainers. They work, they are not that much more expensive than cheap springs, and you won't have to find a set that fits.

twe is titanium so they're lighter and can support a higher redline. it also can't hurt on a block like yours. good luck!

I'm using USDM STi springs/retainers on my DOHC heads. Cheaper than TWE and with the stock redline of 7k and reports of no problems spinning to 8k+....that's alot of bang for buck to me.

For reference: There is a slight difference in freelength between RS springs and STi springs, but the installed height is the same. STi cams have more lift than RS so coilbind is not an issue either. I however, don't have an ECU that lets me spin that high as of yet so I can't reap all of the benefits just yet.

TWE is the best and Rallitek.com sells them the cheapest (even cheaper than TWE themselves).

What turbo are you running and what redline? AS has been mentioned, for many of the guys running RS-T's you just don't need to do this. For higher power levels, they are worth the $$$, and TWE is going to be the best bang for the buck...
