I am sure there is a million thread on what apex seal is good and not.
so far i have boiled down to Mazda OEM and RA Superseal which is the only one i can afford. i know its all in the tune. but i need that final push from someone

from what i read
the ra super seal is harsher on the housing and the oem will last longer.
i am a person who drive this thing 3k a year.
My plan
S5 t2 with n/a rotors
gt35r
stock ports
350-400whp.

If you get the super seals please use OEM Mazda springs. The RA ones I received all had different static spring height measurements and looked "cheap" to me.

i'd use turbo rotors and OEM seals.

y not n/a rotors? its a s4 n/a rotor.

I highly recommend OEM seals, my engine is about 8 years old and was a mazda reman, and I've overboosted it and knocked by accident several times and haven't had any problems at all. I'm frankly surprised it's still together.

we already have to tune the turbo motors really conservatively, raising compression just makes this worse.

^ is it true that if i use s4 n/a rotor, then i should use s4 t2 flywheel?

^if you are using a t2 transmission then yes

iTrader: (9)

One thing i found is when u buy aftermarket clutch/flywheel like act/cusco etc is that they dont specify wheather its for a s4/s5 t2 or n/a

ACT is turbo sized, most anything JDM is turbo sized as they never got non turbo FC's
If theyre NA it will usually say.
And it series doesn't matter as you have to supply the auto counterweight to bolt the flywheel too

i am getting confused with the counter weight. there was no counter weight when i took everything apart. just the flywheel

TougeMonster

iTrader: (1)

On a stock flywheel the counterweight is built into the flywheel
Aftermarket flywheels bolt onto a counterweight from an auto flexplate

^that made lot of sense.

does it really matter were u put the front and rear rotor aslong as u r installing new bearings?
