On racing beat they recommend higher oil pressure, so you do front and rear regulator, BUT with that done does the stock 12a pump put out 110 psi. Racing beat also says to swap the front iron and front cover for an fd one so you get the oil pump. Is this even necessary or is it a race engine thing. Im building a turbo 12a only running 5-10 psi boost im not looking for more than 300-350 hp what would you guys say

 

the pump will give pressure according what the regulators dictate. the stock pump will supply the pressure. use the FD rear regulator and either shim the stock front spring (M5 washers x 2, if i recall) or change it out for the FD one.
where do they say THAT???

 

Rotary tech tips page, i'm assuming that's a race engine setup

 

i have a feeling something got lost in the translation. an REW front housing would not be compatible with a 12A for a few reasons, and making it fit just for an oil pump is sort of silly.

 

I thought it sounded kinda weird, maybe it's something like fc 13b to an fd oil pump. still its sounds strange im assuming its race applications only where you might actually benefit from the supposed flow gain. I knew that it was an oil regulator thing not an oil pump because pumps of any kind dont have a "pressure output" its the amount they are able to flow and then the pressure is set through a regulator. but everything's different so i didn't know how well the 12a pump could handle 100 psi or more

 

they won Daytona a couple times with hardened rotors in an otherwise stock pump...
you want to start with the bigger pump, 8553-14-100, its 83-85 and some other older engines

 

is there a part number or a way to measure so I can see if I have the 17mm

 

8553-14-100 is the part number. to measure it you take it apart and measure it, the oil pump rotor width is the difference

width of these,
