Im rebulding my 93 FD and now im to the point to where i have to choose which apex seals to go with. Ive heard that there is no diffrence between 2mm & 3mm
and since this is my first rotary i wanted some more feedback. Im planing on boosting about 15psi on a single turbo with a big street port and a power FC for engine management. I still dont know yet if its going to be my daily driver.
So whats your take 2mm seals VS. 3mm seals? OEM or Afftermarket?
Thanx

 

you are going to get yelled at for not searching, there was a couple of threads on this earlier in the week

OEM 3 mm 2-piece for max durability

 

thanx i looked but couldnt find any thing.

 

There are alot of thoughts on which is better between 2mm and 3mm. I personally like OEM Mazda 2mm.

 

you didn't search too hard!

Another thing (I thought), was the clearances in the "rotor tips" you might need a wider apex seal to make up for the wear incured.

..normally it's for people looking to make power.

 

Oem 2mm or 3mm all the way unless u can afford ceramic

 

was looking in the range of 450whp would i be safe with say rotory sports double spring 2mm seal

 

Just use OEM seals. Good luck making 450rwhp at only 15psi on 91 octane....

Thread closed, there are a billion 2mm vs 3mm seal threads.
