GOOD USED,  gsl-se wide sump 17mm Mazda Engine oil pumps for Rx7 Rx3 Rx4 etc these will work on all early 12a and 13b front plates from 1974-1985. 

 

PLEASE LET ME KNOW IF YOU HAVE ANY QUESTIONS BEFORE BUYING. they are used the housings are perfectly good shape. If you need me to measure or confirm anything I will do it for you but I've already looked these over to make sure they meet spec, all 4 meet or exceed expectations for good used pumps according to mazdaspeed book specs.

 

I'm in the middle of building a spare 13B 6port turbo motor for my race car so I am selling off some of my older gems unfortunately.

The last pics show difference between early sump pumps these ate increasingly good if you are running oil jets or 1 or more oil coolers and also higher pressure regulators.

Anything above 9000rpm 90psi or 10 per 1000k rpm (minimum reccomended, i would run more 110-120) you will need this pump and need to modify front pump housing and e-shaft windows as well.

Anyway hard to find usually a out 300 all said and done with shipping

Offering these at much less.

Have 4 available.
