performance side seals or springs?
Hi all. I did a little search with little to no results. I was wondering if there were any performance (upgraded) side seals or side seal springs? Currently my na-t s4 has a stuck side seal, and most the SS springs I have pulled out of my engines have been quite tired. I know that I need to use a FD corner seal springs, but are the FDs side seal springs better also?
Thank you.
Thank you.

awesome, ok thank you very much. I am going to guess that the apex springs are better also? Would it be wiser just to use a full FD rebuild kit?

Apex seal springs are the same. Since you have a n/a turbo, I would say your problem might not be only weak springs, but a weak oil pump. The n/a oil pump is smaller, and the rotors may not be getting cooled properly, causing all the side seal springs, and corner seal springs to fatigue and collapse. I would use a Turbo FC oil pump, and a 90-110psi regulator in your new rebuild to ensure a healthy engine.

Maybe I am wrong?

The job of the side seal is to compleat the job of a compression ring it does get a verry little amount of oil for lubercating..
The oil rings & oil 0-rings will hold back the rest of the oil from going into the chamber...
So if that engine was buring\useing oil it is not the side seals fault...

ok, that is what I thought. At first the idea of not getting enough oil sounded good but there was just something wrong. Ok, I think its just bad luck. I am still looking for a 13b-re! haha
Thanks all.
Thanks all.

The rotors are cooled only by oil squirted from the e-shaft oil jets to the inside of the rotor.
GtoRx7 was saying if your NA pump is dropping flow/pressure in the high rpms it will cause less oil inside the rotors to cool them and the rotor temp will rise and de-temper the delicate sideseal and cornerseal springs causing them to collapse.
