the guy i bought the car from said the motor was rebuilt in 98 at 110,000 miles.
while im replacing gaskets on the intake manifolds i notice they are not the correct ones. i go to start the car and adjust the timing and got a loud squeal. the pulley hub and key are scared. im wondering if anything else was even done right. the car has 205,000 miles on it now and i know when i went to change out the clutch the pilot bearing was not there no needles just a metal sleave. the outer part of the bearing. i am considering my options i want to do a rebuild but id prefer not to use the s4 housings any suggestions?

 

the guy originally said 13brew housings were in the car once ive had the car for a while now a year i get around to looking at everything and its s4 housings i wonder if it was even rebuilt anyone know where i can find some good info on parts?

 

With that many miles, i would consider a rebuild or start saving?..

 

13B-REW manifolds cannot be used in an NA application - ever. Mainly because of the port misplacement..but yeah.

What kind of info are you looking for? There's lots of people who do quality rebuilds and porting on the forum, and lots of people who sell parts to do it yourself.

People who rebuild:
Rotary Resurrection (http://www.rotaryresurrection.com/)
Kahren (Name is Kahren on the forum, known for superior porting)

Companies who sell rebuilding parts:
Mazdatrix (http://www.mazdatrix.com/)
Atkins (http://www.atkinsrotary.com)
Rotary Aviation (http://www.rotaryaviation.com/)


While I have no personal experience, from what I have learned on this forum it seems that the only apex seal that is truely worthwhile is OEM Mazda seals. More expensive..but(arguably) best quality.

 

just what kinda rotors and housings would you use to get the most power and also i want to do a large street port

 

ok im thinking of keeping the housings and bridge porting the aux ports. doing a large street port on the secondary and primary ports and running s5 rotors. with some advice from bridgep0rted


and i know from the front stationary gear to the front cover are toast. they have scars that measure .9 into the outer edges. thrust bearings are torn. i will try and get pics up
