I have a full set of ttc performance valve springs that I bought when I did the build. These are for any 1gr-fe engine. Direct replacement of your stock ones. They are quite a bit stiffer and are highly recommended to anyone that is looking to make power in the forced induction world and these are a must to help prevent valve floating. They also make it a lot safer to rev higher. The stock springs won't be enough. Willing to trade or asking $300 shipped for the set of 24 valve springs. Valve springs have maybe 8k miles. These are the ones that TTC sold. They have been great but I just upgraded my entire valve train so I don't need these anymore.
That is where I got them from. cost me $450 shipped. Looking for $300 shipped obo or trade.
